Chinese female professor breaks US blockade technology!The paper developed is harder than steel and can resist shells
The world-famous four great inventions of ancient China are the most profound treasures left by our ancestors in the long history .
Cai Lun, who invented papermaking, replaced the heavy bamboo slips with silk paper, and is recognized as the originator of modern papermaking . human beings all over the world.
And why is Professor Zhang Meiyun of Shaanxi University of Science and Technology known as the contemporary Cai Lun? After years of scientific research, such a kind of paper was born, which
broke people's cognition of daily paper . Daily paper is used for office or life, with different softness and strength, and it is also light and easy to carry. However, the paper developed by Professor Zhang Meiyun is on the harder side. The paper developed is more than 7 times harder than steel. If the superimposed layers are sufficient, its hardness can actually compete with the blocking strength of combat armored vehicles, and
can even resist Attack of high-intensity artillery shells .
The goddess professor refuses a million-dollar salary
After graduating from university in 1982, Professor Zhang Meiyun, like many fresh graduates at that time, also had great
ambitions and wanted to go to the first-tier cities to make his own achievements and achieve his own career, but her school He valued Professor Zhang Meiyun's excellent ability and enthusiastically retained her to teach at the school.
This was a very difficult choice for Zhang Meiyun, who was young at the time. Should he
give up the blue sky outside the school , or should he give up the school's repeated retention of him? In spite of her reluctance to her alma mater and her love for the papermaking business, she stayed in the school that nurtured her for four years and continued her teaching career.
Unexpectedly, she will stay here for 16 years. She devotes herself to the education of students
and plays the role of teaching and educating people with due diligence. Because of his outstanding achievements in education, in 1998, some companies even offered Zhang Meiyun to work with an annual salary of several hundred thousand or even one million. At that time, it was indeed tempting to be able to earn several hundred thousand per year.
We have no way of knowing whether Professor Zhang Meiyun is interested in this , but she has been a people's teacher for many years, and
it is indeed not rich compared with the salary offered by the company , but her later decision is to stick to her position and refuse a million-dollar salary. It can be seen that The professor's love for his career and his persistence in education.
At that time, Professor Zhang Meiyun
still took teaching and educating people as her career goal . Although she had not yet worked in the field of international cutting-edge scientific research, she still had very high requirements on herself. Even as an ordinary people's teacher, she constantly urged herself to improve. He not only strives to improve in terms of teaching and educating people,
but also has high requirements for his professional ability . Professor Zhang Meiyun firmly believes that since he has the responsibility of a teacher, he cannot live up to his own. Students' thirst for knowledge must also allow them to learn something.
In order to implement her strict requirements, Professor Zhang Meiyun did not let up for a moment. As soon as she had time, she learned to absorb relevant professional knowledge by herself, and she also had proper self-assessment for efficient study. Finally, Zhang Meiyun was promoted to professor in 1999. At that time, she was in her 40s. He
gave up the habit of studying , and was admitted to a doctoral degree through his own hard work.
Although she is a professor, she still demands herself as a student in her research field. She often says that in the field of papermaking, she is humble and humble and
needs continuous improvement to achieve perfection. Professor Zhang Meiyun's studious and dedicated spirit has always been in the school, inspiring her students and other teachers.
Break the US technology blockade
At that time, high-performance fiber paper materials, China's technology
could not achieve independent research and development and manufacturing . The initial research and development of materials started abroad. Many foreign companies have a long time in the research and development of materials. Among them, DuPont in the United States is the
The most technologically mature company . The high-performance fiber paper required by various industries in China needs to be imported from abroad.
In order to break through technical barriers and break the technological blockade of the United States, Zhang Meiyun exerted his high standards and
devoted all his efforts to research and development . For the sake of scientific research, she has been sitting at her desk for a long time. The long time at her desk caused her to suffer from a very serious lower cross syndrome. assist.
Once she got through the physical pain, she didn't care about her body at all, and
continued to focus on her scientific research career , often staying up all night or even doing research all night. She suffered from central retinal artery occlusion because of her inattentiveness to her physical condition for many years.
The condition caused her blindness in her right eye, so she had to be hospitalized, but after only two months of hospitalization,
she couldn't wait to return to work when her condition had not improved completely . The dissuasion of family members and doctors was useless. The stubborn Zhang Meiyun decided to return to work.
Fortunately, Huangtian
paid off. Zhang Meiyun and her scientific research team, who held their breath, worked hard day and night under the high-intensity research and development progress, and finally unlocked the password of high-performance fiber paper. Because of their success, China can finally produce its own high-performance fiber paper.
Since then, it will no longer rely on imports, and the field of using this technology has also benefited from this and has made great progress. Therefore, Zhang Meiyun and her team have also won numerous awards in China. The success of this research project
not only breaks the technical barriers of foreign monopoly industries , but also represents a national honor, representing China to speak to the world, and we can also do the technology research and development done by other countries.
A well-deserved scientific goddess
We always have admiration for people like Professor Zhang Meiyun. It is precisely because of the contributions of such excellent researchers that they truly
put themselves aside when conducting scientific research, so that foreign monopoly technologies will be taken one by one. Break, so that Chinese technology can be recognized, and even go to the world.
What makes Zhang Meiyun outstanding is that she has always adhered to her ideals and beliefs. In her philosophy, those who engage in scientific research
need to be able to defend poverty , withstand temptation, and be able to endure loneliness, not only to be indifferent to fame and fortune, but also to be low-key and pragmatic. "She didn't just
chant these as slogans , she did it all with her own practice.
Even though she has made such great achievements in the field of scientific research in China, Professor Zhang Meiyun still adheres to her
philosophy of life , and she
has continued to study hard for ten years . Apart from work, her life is like a calm lake, and she has never been shocked. Make waves.
At work, on the podium, she is a teacher who must
let her students learn real skills . On her desk, she is a scientific research worker who treats her with high demands, for the next one who needs her. Scientific research work continues to give silently,
burning its own light and heat . She is Zhang Meiyun, a Chinese goddess professor, and a well-deserved
"contemporary Cai Lun" .
