After talking for a few days, I have been indifferent to her. I suspect that she is a little romantic and eager to work. -"In Memory of Forgetting". (3) [unfamiliar]: unfamiliar; vulgar person
I know nothing about electronic computers. I am really separated.
1 name gap: there is a gap between two people.
(2) Feelings are not connected, and they don't understand each other: they have not heard from each other for many years and are separated from each other. Our thoughts have nothing to do with our feelings.
(3) the shape is unfamiliar; Amateur: I'm really confused about this technology. Battery is one of the most important applications of diaphragm;
It is mainly to separate the positive and negative plates of the battery to prevent the short circuit caused by the contact between the two electrodes and let the ions in the electrolyte pass through.
Taking lithium ion battery as an example, the performance of separator is explained:
1, good chemical stability-electrolyte is an organic solvent system, and the diaphragm material cannot react or dissolve with it;
2. The tensile strength and breakdown strength are high, meeting the requirements of winding assembly;
3. Higher porosity to increase current density and uniform pore size distribution to avoid local overheating caused by uneven current density;
4, good wettability to electrolyte and high liquid absorption rate, which is beneficial to improving ionic conductivity;
5. It has lower closed-hole temperature and higher membrane breaking temperature, which ensures the safety of the battery. In the structure of lithium battery, the diaphragm is one of the key internal components. The performance of the separator determines the interface structure and internal resistance of the battery, and directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the comprehensive performance of the battery. The popular description of diaphragm is porous plastic film, which is a kind of high value-added material with the highest technical barrier among lithium battery materials, accounting for about 20%-30% of the cost of lithium battery. The main reason for the high price of diaphragm is that some key technologies for manufacturing diaphragm are monopolized by Japan and the United States, and the indexes of domestic diaphragm, especially high-end diaphragm, have not reached the level of foreign products. The technical difficulty of diaphragm lies in the engineering technology and matrix material of pore-making. The engineering technology of pore-making includes diaphragm pore-making technology, production equipment and product stability. Matrix materials include polypropylene, polyethylene materials and additives.
1, melt stretching method
The preparation principle is that the polymer melt crystallizes in a high stress field to form a layered structure arranged in parallel perpendicular to the extrusion direction, and then the so-called hard elastic material is obtained through heat treatment. After the polymer film with hard elasticity is stretched, a large number of flakes are separated and microfibers appear, thus forming a large number of microporous structures, and then the microporous film is made by heat setting. American Celgard diaphragm and other commodities.
2, thermally induced phase separation method
A method for preparing microporous membrane by thermally induced phase separation. It uses high polymer and some small molecular compounds with high boiling point to form homogeneous solution at higher temperature (generally higher than the melting temperature of high polymer), and then solid-liquid or liquid-liquid separation occurs when the temperature decreases, so that the polymer-rich phase contains additive phase, and the additive-rich phase also contains polymer phase. After stretching, low molecular substances can be removed to make interconnected microporous membrane materials. Japanese goods such as Tonen. The literary inquisition in the early years of the Qing Dynasty was not mentioned again until the end of the Qing Dynasty. The most exciting thing is that there are several people in Nanshe [2] who organize and print a collection of posthumous works for the victims; There are also some international students who are trying to withdraw their certificates from Japan [3]. It was not until Meng Sen's "History of Mind Series" [4] came out that we learned the details. Everyone always thought that the curse of words began with criticizing the Qing Dynasty. However, this is not entirely correct.
Over the past year or two, the story of the Palace Museum doesn't seem to be very convincing [5], but it has printed a good book for us, for example, Archives of Wen Prison in Qing Dynasty [6], which is nothing more than Feng Qiyan's Notes on Yi Shi's Two Classics in February of Qianlong's forty-eight years.
Feng Qiyan is a student in Linfen County, Shanxi Province. When Wen Qianlong paid a visit to the Tailing Mausoleum [7], he was wandering on the road with a book in his mind, intending to make progress, only to be arrested first for "acting suspiciously". This book, based on the Book of Changes, is actually a nonsense book, which is not worth copying here, but it has a long autobiography-like article at the end, but it is very special-
"Again, I'm here. I don't want to do anything, and there's nothing to ask, but an unfinished business, please tell your majesty the reason. My name is Feng Qiyan. I have tasted my aunt Zhang Sanjia. When I meet my daughter, I can marry her, but my hatred is not enough to do this. This girl is my daughter, and she is seventeen years old. She is the second daughter of Zhang Shoutuan, director of Dongguan Pure Cattle Factory. I went to my fifth aunt's house again, and I could marry her when I saw my daughter, but my hatred was not enough. This woman's name is Xiaofeng, and she is thirteen years old. Although she is not a mandatory figure, she is the second daughter of Du Yue, the Sheng Rui in downtown JD.COM. If you use your majesty's power to send a servant, choose a fast horse, drive to Linyi every day and ask the Linyi local official,' Is there Zhang Shoutuan in the promotion of Dongguan Chunniu factory director?' If so, then this matter will be harmonious. Ask again:' Is there a Aduyue in Dongcheng Shengrui?' If so, then this matter will be harmonious. If these two things are in harmony, the minister's wish will come true. However, here I am. I don't know if your majesty's words are true, but will it be stronger with such things? I mentioned it during my special speech. "
Is there any malice in this? But I was fascinated by the popular story of gifted scholars and beautiful women at that time and wanted to become famous in one fell swoop. The son of heaven is the matchmaker, and my cousin hugs me. Unexpectedly, the fact ended badly. Yuan Shoudong, governor of Zhili, intends to play the crime of "reading the first book, dare to mix the scriptures in front of the Lord, and use the last word, which is especially arrogant." The crime of nuclear feelings is more serious than the ritual conflict. Feng Qiyan committed a crime and was sent back to Heilongjiang and other places to be enslaved. As soon as the Ministry returned to Japan, it removed the tattoo as usual. " This talent is the last one to go through customs, baby.
In addition, although this case is not so elegant, it is not reactionary. Some are reckless; Some are crazy; Some country songs are pedantic and elegant, so I really don't know the taboo; There are ignorant people who really care about the royal family. And fate is probably very tragic, either in the year, genocide, or beheaded immediately, or "beheaded" [8], but still can't live.
These things, on the one hand, let us feel the cruelty of the Qing Dynasty, and on the other hand, let us feel the pity of the dead. But on second thought, it's not that simple. The reason for these tragedies is only to "separate".
Manchu itself is strictly divided into master and slave. When a minister plays things, he must be called a "slave", while the Han people call him a "minister". This is not because it is a "Chinese Emperor" [9], and it is treated specially. Tin is famous for its reputation. In fact, it is different from the "slave" in Manchu, and its status is lower than that of "slave". Slaves can only follow, not talk; Of course, it is impossible to comment or praise yourself. This is "unexpected" [10]. For example: Master, some corners of your robe are broken. I'm afraid it will be more serious if we drag on. You'd better repair it. The speaker thinks he is loyal, but in fact he has committed a crime, because there are others who are allowed to say such things, and not everyone can say them. Nonsense means "wanting to do something wrong" and of course "culpable of punishment". If you think that you are "loyal and responsible", it is only your own confusion. There was an examination question in the late Qing Dynasty: On Xiang Yu Napoleon. One came from the countryside to take the exam. Without thinking, he immediately wrote with a wave of his brush: "Xiang Yu pulls a thousand pounds, but the wheel is broken ..." The result of the court exam is not difficult to imagine, and this person only got the last place. In a few words, the image of an ignorant and reckless juren is vividly portrayed. In the early 1980s, when I read this story in a Chinese newspaper run by Lu Xun's hometown, I couldn't help laughing. Because I am young, I stop laughing and don't think deeply. After a long time, you will forget.
I joked with my friends the other day and told the story again. A friend's face is serious and to the point, but ignorance creates a barrier. I admire my friend's unique insights and incisive words. Looking back on my own experience, there are also a few bumps, which have been bumpy so far. I remember a few years ago, the author talked with my friends about Liu Bannong, the founder of vernacular Chinese. I said that my husband was very talented and invented the female "she". My friend said no, but I couldn't tell the origin of "her". The fight turned red and broke up in discord. The author has met face to face many times, and friends are no longer friends. This may be the cause of the diaphragm. Visible diaphragm is so terrible!
Different countries and languages will create obstacles; Different nationalities and beliefs will also create barriers; Differences in culture, literacy and knowledge, even the size of age, will also create barriers. Diaphragm is really terrible, because it will breed distance again soon. When friends have a distance, they will break off contact; With the distance between colleagues, there will be disunity; When there is a distance between husband and wife, they divorce. Imagine the distance between countries and regions, between units and departments. What will happen? From this, it is not difficult to see that the diaphragm will cause all kinds of unpleasantness, some make people fall into meditation, some make people sigh, and some make people cry.

[1] This article was first published in1July 5, 934, the first issue of Shanghai Xinyulin, signed by Du.
[2] "Nanshe" Literature Group was founded by Liu Yazi and others in Suzhou on 1909. The society advocated the anti-Qing revolution with poetry. After the Revolution of 1911, its members were disintegrated invisibly in 1923. Collected works of victims of literary inquisition in Qing Dynasty compiled and printed by members of Nanshe Society, such as Wu Jiming's Collection, Dai Bronfu's Record and Legacy Record, as well as handwritten family instructions for Lv Wancun, are mostly included and edited in the National Essence Series.
[3] In the late Qing Dynasty, some students studying in Japan collected the works of adherents of the late Ming Dynasty from Japanese libraries, such as Ten Days in Yangzhou, A Brief Introduction to Jiading Slaughterhouse, Zhu Shunshui Collection, Zhang Cang Water Collection, etc. After printing, it was imported into China to advocate the anti-Qing revolution.
[4] Meng Sen (1868-1937) was born in Wujin, Jiangsu, and was a historian. He studied in Japan and later served as a professor in the history department of Peking University. Series History of Mind, three episodes, published in1916-1917, all of which are textual research. There are Zhu Guangdan's case, "Justine's Classic Examination of Jiangxi Proposition with Irony" case, "Ziguan" case and "Random Records" attached to the third case (Henan, Shandong, Shanxi Wei). When discussing the murder of Wang Xihou's factor officer, he said: "The man of Xihou is also a pedant wearing a headscarf, just like Dai Mingshi, and he has absolutely no intention of being humble and incorruptible. Dai is proud of ancient prose and Wang is proud of science. Both of them like writing. I've been writing for a long time and I've learned everywhere. So in the next season, I can't wait to catch its legacy, and the reason why Dai was killed is also. In the word book, Kangxi Dictionary is a family statement, among the few. The reason why this king was born is also. "
[5] refers to the theft and sale of cultural relics in the Palace Museum. The Palace Museum is an institution that manages the buildings, antiquities and books of the Forbidden City and its subordinate areas in the Qing Dynasty. 1932- 1933 When Yi Peiji was the dean, many antiques were stolen and sold, so Yi Peiji was accused.
[6] Archives of Wen Prison in Qing Dynasty was compiled by the Literature Museum of the Palace Museum and published by the National Peking Research Institute. The materials come from the archives of the Ministry of Military Affairs of the Palace Museum, Zhu Pi's memorial and palace records. The first series was published in May 193 1. For the case of Feng Qiyan, see the eighth edition of Archives of Literary Prison in Qing Dynasty (1published in July 933).
[7] The mausoleum of Yong Zhengdi (Yin Zhen) in the Qin Mausoleum is located in Yixian County, Hebei Province.
[8] The legal system of the Qing Dynasty: prisoners sentenced to death but not executed immediately are temporarily remanded to the autumn trial (in mid-August every year, the Ministry of Punishment and officials discuss the trial books of various provinces in detail and request a ruling), which is called "waiting for prison" and is different from "waiting for prison".
[9] "Huang Yanzhi" refers to the Han nationality. Yanhuang, the legendary ancient emperor of China, Yan Di and Huangdi.
[10] For the sentence "unexpected", see I Ching Chuang: "A gentleman can't think of it."
[1 1] Kang Youwei (1858— 1927), a native of Nanhai, Guangdong Province, was the leader of the Reform Movement in the late Qing Dynasty. After the failure of the Sino-Japanese War of 1894-1895, the Qing government signed the treaty of shimonoseki with Japan on 1895. Kang Youwei and the mainlanders in Beijing at that time wrote to Emperor Guangxu, demanding "rejecting peace and moving the capital to reform", which became the prelude to the Reform Movement of 1898.
