Training summary and experience 1
In practice, I strictly follow the training procedures. As a fledgling college student, I will not relax my demands on myself. I hope that every task in the future can be treated with the original enthusiasm for learning. During this period of training, although I often feel bitter and tired, I have fun in suffering and happiness in being tired, and I have also shown great efforts and seriousness. The main content of this training is machine maintenance, but I have benefited a lot and felt a lot. What I feel most is as follows:
First, training is a test of an individual's comprehensive ability. If you want to finish your work well, you need not only profound basic knowledge of office, but also certain practical ability, operational ability, ability to deal with unexpected faults and proficiency in common office software. As a staff member, you also need to have strong expression skills, and be good at guiding yourself to think and adjusting the atmosphere of getting along with others. In addition, you should have strong adaptability, organizational management ability and strong perseverance.
Secondly, this training, I deeply realized the importance of accumulating knowledge. As the saying goes, if you give students a bowl of water, you have to have a bucket of water. I was deeply moved by this sentence. Office, I used to feel very easy to operate, but when my master asked me to complete a product statistics data and records, I was at a loss, feeling completely different from what I usually learned in computer classes, which also made me feel ashamed. Because I always thought that learning these things well had little to do with my major, but I didn't know that my job was not to specialize in one aspect, but to examine our comprehensive knowledge level. This internship has enhanced my confidence and courage in graduation and employment.
Training summary and experience II
How time flies! In a blink of an eye, a week's training life quietly passed, but the training process is still vivid.
During the training, I learned a lot, which not only gave me a new understanding of VB programming in theory, but also improved my practical ability. It's really what I have learned, and I have learned a lot about being a man, which has benefited me a lot. I personally felt the combination of theory and practice, which opened my eyes. It is also a preliminary test of what you have learned before! This training really benefited me in my future study and job hunting. I believe these valuable experiences will become an important cornerstone of my future success in a short week.
As a sophomore, after almost a year and a half of study in school, I have a rational understanding and understanding of programming. I have been busy studying theoretical knowledge at school, and I have no opportunity or corresponding experience to participate in the design and development of the project. So before the training, the program design was abstract to me, and I didn't know how to complete a complete program.
The project I am doing this time is personnel management system, including login, employee database, attendance database, salary database, business information and so on. At the beginning of the training, only a few simple interfaces were made, which is actually relatively simple. On the third day, the basic part of the code was written, but there were many problems during debugging. Moreover, sometimes due to thoughtlessness and carelessness, there will be big mistakes in the code. The teacher taught us many simple and practical skills. It also makes us realize that in order to complete a module comprehensively and completely, we must first design a good program, comprehensively analyze what will be used and consider possible situations. So under the guidance of the teacher, all the problems were solved smoothly.
There are many shortcomings in the writing of this program. Some functions may be incomplete and imperfect, but I feel that I have done it seriously and learned a lot from it. In the future, I will make up for my lack of knowledge points, learn to draw inferences from others and learn to master them. The most important thing is to get rid of careless and thoughtless habits. I think I will improve this program in the future and try to apply it to my life.
During the training period, it brought me not only an experience, but also a fortune in life. As the saying goes, what you get on paper is always shallow. It is not profound to study without applying theory to practice. Nowadays, college education is based on theory, and it is beneficial for me to have the opportunity to practice. I am about to graduate and go to the society. I believe this internship will help me to take part in the work in the future.
Although the hardships and smiles along the way have gained something, what we have learned is the beginning. New tests and choices must be constantly struggled and honed. Please don't let our young time leave too many regrets!
Training summary and experience 3
Engineering geology training for one and a half days, has been observing three stations. But because of the heavy rain before training, we finally went to two stops. One is the dense caves, and the other is the Conghua fault zone.
On June 27th, after the teacher talked about some matters needing attention when going out in the morning, we packed our bags and set off for the first stop of our investigation-Mishidong. First of all, the teacher explained the content of this practice and put forward four questions, so that we can carry out this practice purposefully. These four questions are:
1. Which of the three rock classifications is the rock here?
Second, what rocks are there here?
3. Why are the rocks here so broken?
4. What is the weathering degree of the rocks here?
With questions, we observe the rocks here. It is found that the rocks here are mainly shale and sandstone, and a few are magmatic rocks, but the rocks here are layered rocks. Because there are a lot of shale and sandstone in the rocks here, these two kinds of rocks are typical rocks in layered rocks. After the teacher's final summary, we understand that the rocks here are layered rocks, not only because of its large distribution of shale and sandstone, but also because of its bedding, which tells us that the rocks here are layered rocks.
Sandstone: More than 50% of the grain size is 0. 074~2mm sand cementation. According to grain size, it can be divided into coarse-grained, medium-grained, fine-grained and silty sandstone; According to its main detrital composition, it can be divided into timely sandstone, feldspathic sandstone and lithic sandstone. , sandy structure and bedding structure. We found more sandstone siltstone and feldspathic sandstone here. As the name implies, the texture of shale is like a page of homework paper, which becomes like this under strong pressure.
Because the place we observed this time was next to a newly-built expressway, which was dug out of the mountains and the rocks were bare. During this period, there was plenty of rain, and the rocks near the vegetation have become soil and completely weathered. From top to bottom, the weathering degree of rocks is getting lower and lower, and there is only slight weathering near the foundation. The reason why the rock is so broken is because of the activity of the rock stratum, the action of internal stress and external stress, and also because the integrity of the rock stratum was destroyed shortly after construction.
Finally, we also measured the incidence, but because of operational reasons, our data are biased and cannot be recorded as experimental data.
On June 29th, we went to the second stop-Conghua Fault Zone for observation. This time, the problem is similar to last time. The rocks here are three types of metamorphic rocks, including mylonite and rhyolite. There are also magmatic rocks distributed in it, and we found that rocks similar to shale are also distributed in it, and later it was known that it was schist.
Because there was a lot of rain during this period, the rocks there were severely eroded by rain, which was lightly smashed with a hammer, and serious rhyolite was crushed into mud by hand, so we basically broke the samples by hand this time. Most of the rocks here are severely weathered and severely damaged by rain, which affects our observation.
It is located in the Conghua fault zone, where the crustal activity is intense, the rock strata change greatly, and man-made destruction, so the rocks there can not be crushed and used, but become mud and sediments. Next to the battlefield, the raw materials are the rocks there. After returning to school, we observed the rocks beside the school path, which were limestone. The magic of nature makes these ordinary rocks graceful and become a beautiful landscape in our school.
The training time is not long, and I don't know enough about geology. However, we are majoring in road and bridge, so we don't have to study as thoroughly as environmental geology. We just have a basic understanding of the proportion of geology in our road and bridge construction, which is the basic part. I paid attention to the parts of the expressway when I went out. After the road is completed, the roadside should be protected to reduce the probability of landslide accidents, which is related to the geological trend.
Through this training and the last survey training, I understand that our road and bridge major is not easy. It is not only limited to building roads and bridges, but also to learn how to coordinate with nature and make way for building bridges while minimizing the damage to the environment. This geological training has also brought us closer to nature, let us see the scenery that we can't see or pay attention to at ordinary times, and see the wonders of nature and the beauty in rocks.
Training summary and experience 4
Electronic and electrician training is an important practical teaching link in vocational education. Through practical training, let us know the basic knowledge of manual welding and radio, so that we can master welding tools, requirements and methods, welding methods in modern electronic technology, reading, testing and use of common electronic components, basic working principle and maintenance methods of radio. Let us know the working characteristics and simple maintenance methods of electronic products, and cultivate our professional skills in obtaining electronic assembly technology. Through the study of basic theory, it is of great significance for us to learn to use basic knowledge, train basic skills and enhance practical ability.
I. Main contents of training:
1, manual welding practice
The essentials of welding technology can be summarized by "five steps": preparation before welding, heating of weldment, melting of solder, removal of solder and removal of soldering iron.
Before soldering, we should remove the oxide layer on the surface of the component and bend the pins of the component. With tweezers, the left hand clings to the resistor and clamps the pin of the component, so that the bent part of the pin has a gap of more than two millimeters from the component. Some components should be bent according to the corresponding hole spacing on the circuit board because of the large hole spacing.
Manual welding practice is mainly about the use of electric soldering iron. Before using the soldering iron, be sure to pay attention to that the plug of the soldering iron must be plugged into the socket of the right hand, not the socket of the left hand. If you are left-handed, put it in your left hand. Before electrifying the electric soldering iron, straighten the wire of the electric soldering iron first, and check whether the insulation layer of the wire is damaged, so that the wire cannot be wrapped around the hand. After electrifying, the electric soldering iron should be inserted into the soldering iron holder, and check whether welding head will touch wires, schoolbags or other flammable items. Do not touch the heated metal part of the electric soldering iron with your hands during and after heating, so as to avoid scalding or electric shock. Sponge on the soldering iron frame should be cleaned in advance. When using an electric soldering iron, the welding head should be tinned first to protect the welding head, and the welding head will be white after tinning. Excess tin on the welding head can be wiped off the sponge with water on the soldering iron rack. When using the soldering iron, the soldering iron cannot melt the solder when the temperature is too low, or the solder joint is not completely melted, which becomes unsightly and unreliable. Too high will "burn" the soldering iron (although the temperature is very high, you can't get tin). In addition, the welding time should be controlled. If the soldering iron stays too short, the solder will not completely melt, forming "virtual soldering", while if the soldering time is too long, it will easily damage components or tilt the copper foil of the printed circuit board.
We carried out cube welding and practice plate welding operations. In practice, we should constantly sum up, grasp the heating time and the amount of tin delivered, and lay the foundation for the assembly and welding of electronic kits.
2. Assembly of electronic kit
(1) Identification and detection of components: There are many components in the electronic suite, including diodes, triodes, resistors, capacitors, electrets and so on. Before assembly, the components should be identified and tested to see whether their nominal values are close to the measured values and to determine whether the components meet the requirements. It should be noted that the resistance should be distinguished according to the color change, the anode and cathode of diode and electrolytic capacitor, the connection order of three pins of triode and so on.
(2) Welding of printed circuit board: Assemble the components on the circuit board according to the circuit diagram, and then weld.
(3) Electronic product debugging: If the debugging is unsuccessful, check where the problem lies and then solve it; If the debugging is successful, the test is completed.
Second, the training income.
1, have a preliminary and systematic understanding of electronic technology theory. Through the practice of electrical and electronic engineering, I learned the welding skills of common components and circuit components, the design, production and process flow of printed circuit board diagram, the working principle and function of components, and accepted the basic welding training of electronic engineers, which made my basic welding technology and debugging ability get preliminary training and exercise, thus promoting my comprehensive mastery of electrical and electronic technology and comprehensive development of knowledge and ability, laying the foundation for future study and work after graduation.
2, their hands-on ability has been greatly exercised. During the internship, I exercised my hands-on ability and improved my ability to solve problems. For example, when the telephone was assembled and debugged, it was welded at first, but my diode stopped working when it was connected to an external circuit. Later, I remembered that there was no difference between installing two polyester capacitors, so I changed the positions of the two capacitors and it was fine.
3. More specific gains:
(1) learned how to read the resistance with the color ring, and then used a multimeter to verify whether the reading is consistent with the actual situation, and then nailed the resistance on paper and marked the data to improve the welding speed in the next step;
② Know what rectifier diodes, zener diodes, switching diodes and light emitting diodes are; Learned how to measure diodes and how to identify the positive and negative poles of diodes; When measuring the rectifier diode, the diode can be connected to the buzzer of the multimeter, the red contact pin is connected to the positive electrode, and the black contact pin is connected to the negative electrode, thus measuring the DC voltage. If it shows 0, it means a short circuit. If 1 is displayed, it means open circuit or reverse direction;
③ Learned how to measure the magnification of triode with multimeter and how to identify the three pins of triode "B", "E" and "C";
(4) Learn to recognize and read capacitors, and ceramic capacitors have no positive or negative electrodes; The long leg of electrolytic capacitor is "+"and the short leg is "-".
⑤ Know what electret, synchronous crystal oscillator and other components have never been touched before.
6. Understand the welding principle, technology and skills.
⑦ Understand the general production process of electronic products.
I have improved my teamwork ability. For example, when assembling a telephone, I often need someone to help me hold down the circuit board or hold the tin absorbing board. Several students on the phone always help each other and discuss problems when they need help. These processes have greatly cultivated my ability of unity and cooperation.
Third, practical experience.
1, when welding, put the soldering iron at the solder joint for a while before sending it to solder wire. After the tin wire is melted, put the tin wire opposite the soldering iron to weld a better solder joint.
2, sharpening the knife does not mistake the woodcutter. When I first assembled the electronic suite, I was anxious to insert the components into the circuit board according to the schematic diagram and then solder them. The night before I made the electronic kit for the second time, I took out the instruction manual and read the previous instructions carefully, only to find that there was a suggested installation order and a special instruction that the electrolytic capacitor should be installed horizontally to prevent the cover from being difficult to cover. I took out my incompletely soldered circuit board and saw it. Fortunately, only one electrolytic capacitor was welded, and other welded components were not welded in the order recommended in the manual. That night, I studied the schematic diagram for more than two hours before I figured out how to install it. From this incident, I deeply realized how important it is to be prepared. Most people were in a hurry to weld, so they didn't read the instructions carefully. I followed everyone in a hurry to weld, wasting more time. In the future, we will definitely pay attention to making full preparations first, so as to know fairly well and improve efficiency.
3. Be careful and patient in everything you do. Both the welding operation and the assembly of electronic kits require patience and care. When welding, two solder joints are welded together carelessly, which is easy to cause short circuit, so we need to be extra careful. There are many dense solder joints on the circuit board when assembling the electronic kit. Without enough patience, it is impossible to complete the assembly task.
4. I enjoy the sense of fulfillment and accomplishment brought by the electronic and electrical practice. Since the first class, I have been full of enthusiasm for this course and have been very focused. I am very keen on welding cubes, practicing circuit board welding or assembling electronic kits. Once I start, I can forget the passage of time. After every step, I am as happy as a child and enjoy the "sense of accomplishment" and "sense of accomplishment" brought by this course.
It is not difficult to do anything as long as we put our heart into it. When I first got the components of the test electronic suite, I had a headache, because I knew almost nothing about other components except resistors. I took out a bunch of capacitors and diodes, but I couldn't tell what capacitors and diodes were. When checking the bill of materials, many things don't know what it is, so we have to look at the model specifications on the bill of materials in an attempt to find information in the nominal values of components. After the first lesson of assembling the kit, I haven't completely checked the components. I was worried about whether I could finish the assembly task in the next class. In order to complete the task, before the second assembly class, I compared the telephone in the dormitory, studied the instructions carefully, and judged what many unknown parts looked like according to various information. The second assembly class, finally assembled. I almost jumped with excitement when I heard the telephone ring.
6. Practice makes perfect. When the circuit board was first soldered, the soldered points were very unqualified, either round or adjacent points stuck together. Later, I learned and asked questions from students with good skills, and soon mastered certain skills. The better I weld, the more confident I am. Finally, when assembling the electronic kit, you can be skilled in welding.
Training summary and experience 5
How time flies! In a blink of an eye, my long-awaited training week is over. After two weeks of practical training, I learned a lot of knowledge. Looking back, I really gained a lot these days. Under the patient guidance and encouragement of the teacher, the internship task was successfully completed and the expected goals and requirements of the internship were achieved as a whole. This internship gave me a comprehensive and systematic practice opportunity, which consolidated my theoretical knowledge and enhanced my practical operation ability. From practice, I further realized the importance of disassembly and assembly of CNC machine tools for our CNC maintenance specialty. In my future work, it is not enough to have theoretical knowledge, but also to be able to apply theory to practice. The teacher's requirements for us are: we must complete all the internship links with a serious and rigorous attitude and a highly responsible spirit.
On the first day when the teacher went to the training room, he told us about the discipline and related events in training. The teacher began to explain to us the basic knowledge of fitter maintenance and the importance of CNC maintenance. In order to let us know how to do better in the future training, the teacher particularly stressed the need to take notes during disassembly and asked us to keep a training diary every day. In this training, I learned a lot, such as patience. I used to be in a hurry to get things done, so we had problems with the first assembly and added two nuts after the assembly. Accurate assembly is required. If it is not accurate, it will easily lead to safety accidents and cause great economic losses or death. At first, we were all very active, but later, when the number of demolitions increased, we felt a little bored. Then I thought maybe we were just beginning to feel fresh. So I patiently drew, when we assembled the spindle box spline, it always failed to fit, and then it caught fire, but the more fire it got, the more it failed to fit. Later, I calmed down and put it together. From this incident, I understand that patience is really important.
Confidence is also important. Without self-confidence, it is difficult to achieve great things. Celebrities have said that confidence is the key to success. It is impossible for our CNC maintenance major to learn future faults or problems in school. We can only succeed if we are bold and cautious and do it boldly and confidently on the basis of understanding the principle.
What I learned deeply from this training is how to use new tools. We are now in an era of rapid development. Whether we can use the new tools correctly and effectively will largely determine whether we can succeed. Secondly, it is our attitude. If we don't have a good attitude towards our work, no matter how high our ability is, it's hard to be recognized. It is attitude that determines everything.
In this training, what I have learned most is the combination of theory and practice, and practice is the only criterion for testing truth. Theoretical knowledge is important, but theory without practice is empty talk. Only by truly combining theory with practice and applying theory to practice can we better display our talents. I used to think I could read and understand. After this training, I finally understand that what has not been practiced does not belong to you. As the saying goes, "it is better to believe in books than to have no books." We should read good books, not dead books. What society needs now is people with strong hands-on ability, not people with good theory, which is even more important for our higher vocational students. The goal of our school is to train people with first-class professional skills.
During the training, I feel that I also have many shortcomings, such as my work attitude is not positive enough and my study is not serious enough. I believe that through my efforts, I will definitely get rid of these shortcomings in the future I firmly believe that through this period of internship, the practical experience gained will benefit me for life, and will be constantly verified in the actual work after graduation. I will continue to understand and appreciate what I have learned in my internship, and apply my theoretical knowledge and practical experience to my future practical work to fully demonstrate my personal value and life value. Strive to realize my ideal and bright future. How can you see a rainbow without experiencing wind and rain! "I believe that my firm confidence and my firm will will will surely realize my beautiful ideal and embark on my own road to success.
