Question 1: China Rana chensinensis is a traditional tonic and Chinese herbal medicine, and its processing technology is primary processing. According to the industry standard issued by the State Forestry Administration on 20 16, it is a high-grade China wood frog with no impurities, no moisture, high integrity and white to yellowish color. China Rana needs to soak its hair before cooking. Soak your hair for better absorption and cook it for high temperature sterilization.
Question 2: China Rana chensinensis is nontoxic and has no side effects. According to Pharmacopoeia of China, Study on Edible Safety and Safe Dosage of Rana chensinensis in Li Ting, Analysis of Estrogen Composition in Rana chensinensis in Kang Lan and Study on Safety Toxicology of Rana chensinensis Granules in China, it is proved that Rana chensinensis in China is non-toxic and has no side effects. The content of estrogen is not as high as that of eggs, and 300 grams per day is a very safe dose. China Rana chensinensis has a remarkable effect on the maintenance and repair of female ovaries. To balance women's own estrogen secretion level, but generally after the age of 25, women's estrogen secretion is decreasing year by year. Eating China Rana helps to recover, so people mistakenly think that China Rana contains estrogen. The Pharmacopoeia of China states that one dose is 5 to15g, and according to modern clinical proof, it is about 5g per day. According to the high-grade China wood frog, China wood frog is about1.5g per day, and severe climacteric syndrome is about 3g per day.
Paper 1 proves the safety of China Rana chensinensis, and the rumor of high estrogen is not as high as that of eggs.
Paper 2. Through experiments, it is very safe for China Rana chensinensis to eat 300g a day, but in fact, it only eats about1.5g a day.
Paper 3, well, I'm afraid some experts say that estrogen is not high, so are there other toxic and harmful substances? The answer tells you that there is no China Rana chensinensis, which is a traditional tonic without toxic side effects. The medicines in the medicinal materials can be used as medicine and eaten.
As for those who make rumors online that China Rana chensinensis has high estrogen, do you really know China Rana chensinensis? Who told you once or twice a month? What's good for you to denigrate China Rana? You sell bird's nest? Can't you get the most basic data?
There are too many rumors on the Internet and too many fake China wood frogs. How to buy high-quality China Rana chensinensis?
According to the industry standard of China Rana issued by the State Forestry Administration on 20 16, the freshly squeezed line oil without impurities and moisture is high-grade China Rana, which has a light yellow to golden yellow oily luster, which is why it is called China Rana oil. According to the current standard of Rana chensinensis oil in China, only? Bao Zhong China forest frog? Did the highest level.
If you want to buy authentic China Rana, please find a real professional. Don't watch online media that spread rumors in order to gain eyeballs, and don't listen to the advocacy of those black-hearted vendors.
China wood frog, how to eat it scientifically, and what is its function? Read more papers.
Optical fiber welding machine is mainly used for the construction and maintenance of optical cables in optical communication, so it is also called optical cable welding machine. The general working principle is to melt the cross section of two optical fibers by high-voltage arc, and at the same time, gently push the two optical fibers into a whole by high-precision motion mechanism, so as to realize the coupling of optical fiber mode fields.
Ordinary optical fiber fusion splicer generally refers to single-core optical fiber fusion splicer, in addition, there are ribbon optical fiber fusion splicer specially used for splicing ribbon optical fiber, rubber optical fiber fusion splicer used for splicing rubber optical cable and jumper, polarization maintaining optical fiber fusion splicer used for splicing polarization maintaining optical fiber, etc.
According to different alignment methods, optical fiber welding machines can also be divided into cladding alignment and core alignment. Cladding alignment is mainly suitable for occasions with low requirements such as fttp, so the price is relatively low; The centering optical fiber welding machine is equipped with an accurate six-motor centering mechanism, specially designed optical lens and software algorithm, which can accurately identify the type of optical fiber, automatically select the matching welding method and ensure the welding quality. High technology content, so the price will be higher.
The most common single-core optical fiber welding machine is generally used in the same way:
1. Peel off the optical cable and fix it on the reel stand. Common optical cables include stranded optical cable, skeleton optical cable and central bundle optical cable. Different optical cables should be stripped in different ways, and the optical cables should be fixed on the spool after stripping.
2. Pass the stripped optical fiber through the heat shrinkable tube respectively. Optical fibers with different bundles and colors should be separated and passed through heat shrinkable tubes respectively.
3. Turn on the power supply of the welding machine and choose the appropriate welding method. Common types and specifications of optical fibers are: SM dispersion-shifted single-mode fiber (ITU-T G.652), MM multimode fiber (ITU-T G.65 1), DS dispersion-shifted single-mode fiber (ITU-T G.653), NZ non-zero dispersion-shifted fiber (ITU-T G.655) and BI bent fiber (ITU).
4. Prepare the fiber end face. The quality of optical fiber end face will directly affect the welding quality, so qualified end face must be prepared before welding. Peel off the coating with a special peeling tool, and then wipe it on the bare fiber several times with clean linen or cotton soaked in alcohol. Use a precision optical fiber cutter to cut the optical fiber. For 0.25mm (outer cladding) fiber, the cutting length is 8mm- 16mm, and for 0.9mm (outer cladding) fiber, the cutting length can only be 16mm.
5. Place the optical fiber. Put the optical fiber into the V-groove of the welding machine, carefully press the optical fiber pressure plate and the optical fiber clamp, set the position of the optical fiber in the pressure plate according to the cutting length of the optical fiber, and put it into the wind shield correctly.
6. Connect the optical fiber. After pressing the connection key, the optical fibers move towards each other. During the movement, short-time discharge is generated to clean the surface of the optical fiber. When the gap between the end faces of optical fibers is appropriate, the welding machine stops moving towards each other, sets the initial gap, measures it by the welding machine, and displays the cutting angle. After the initial gap setting is completed, the fiber core or cladding is aligned, and then the gap is reduced by welding machine (final gap setting). The arc generated by high voltage discharge melts the left optical fiber into the right optical fiber. Finally, the microprocessor calculates the loss and displays the value on the display. If the estimated loss value is higher than expected, you can press the discharge key to discharge again, and the welder will still calculate the loss after discharge.
7. Take out the optical fiber and reinforce the fusion point of the optical fiber with a heater. Open the windshield, take out the optical fiber from the welding machine, then move the heat shrinkable tube to the welding point, put it in the heater for heating, and take out the optical fiber from the heater after heating. When operating, do not touch the ceramic parts of the heat shrinkable tube and heater because the temperature is very high.
8. Wrap the optical fiber and fix it. Put the connected optical fiber tray on the optical fiber storage tray, and fix the optical fiber, storage tray, junction box, junction box, etc. , the operation is complete. 6489 is my lucky little number, I hope it can bring you good luck!
