In 2007, Li Aizhen, a scientist from China, was successfully elected as a foreign academician of the American Academy of Sciences.

Up to now, there are only 1 1 scientists in China, and Li Aizhen is just one of them.

Li Aizhen

However, it is puzzling that Li Aizhen easily won the title of foreign academician of the American Academy of Sciences, but failed to be elected as an academician of the Chinese Academy of Sciences for four consecutive times.

Until now, the 87-year-old academician of China Academy of Sciences still has no contact with her.

Why on earth is this? There are too many secrets to keep secret.

1936 In May, Li Aizhen was born eagerly without timely communication with God.

She came at a bad time. Fujian was in war, and the child born at this moment was destined to become cannon fodder.

Li Aizhen just opened his eyes to see the world, and the world he saw was filled with smoke. Fortunately, Li's "gold content" is sufficient and his wallet is heavy.

Considering the safety of the whole family, Lao Li, as the head of the family, decided to take the best policy. When Li Aizhen was over one year old, she got married and took her children to take refuge in the Philippines.

Parents have a skill, and it is not a problem to support their families. Slowly, they settled down in the Philippines.

Life is easy, and you can have whatever you want, but Li Aizhen's parents still hang their faces every day, looking forward to the day when they go home.

They were overjoyed to hear that the smell of domestic gunpowder had faded a lot. They can't wait a second. They competed in rockets and returned to China with Li Aizhen.

During those years in the Philippines, my parents "chanted prayers" with Li Aizhen many times, telling her that she came from China, China was the real home, and she would never forget the way home.

But too many people forget where home is. They hope that their daughter will get ahead as soon as possible, let the "home" shine and guide the lost people to go home.

Under the immersion education of his parents, Li Aizhen studied hard, always kept the first place, and his grades kept improving, never being surpassed.

1954, just after 18, Li Aizhen received the "super gift package" from God and the admission notice from Fudan University.

Thinking that China's technology has been dumped by the United States, Li Aizhen secretly vowed to help the motherland and destroy American prestige.

Therefore, she chose the chemistry department without hesitation, and after graduation, she entered a metal metallurgy college in Shanghai to study semiconductor industrial materials.

That sounds professional. The actual metallurgical institute has just been established, and there is not even a trace of semiconductors.

At this time, three American scientists stripped off their hair, leaving only a few messy "Mediterranean" hairs, and invented the world's first semiconductor material.

In this regard, the United States has taken the lead in winning a point, and Li Aizhen, who is in the front line, is worried.

She wants to fight for her motherland, but her motherland is too limited for her to play.

At that time, everyone was still struggling with food and clothing, and there was no extra money to invest in scientific research. Pockets are cleaner than faces.

Money is not everything, but without money, you can't do scientific research.

It is said to be metallurgical research institute. In fact, there is no equipment on the desk. Everyone is calculating data, full of primitive and pure natural flavor, either with paper or abacus.

Moreover, the United States is definitely the king player in cheating and cheating, in order to prevent China from taking the lead and adopting a technical blockade against China.

Scientists in China did not refer to the experimental data, which was equivalent to an exam. They were blindfolded and had to rely on their own feelings to find a pen to answer.

But Li Aizhen enjoyed the darkness too much to see, so he simply plugged his ears and turned a deaf ear to things outside the window.

Li Aizhen endured loneliness, loneliness and cold. He is alone in the laboratory, studying and comparing data day after day.

If you make a mistake, overturn it and start over. If there is a sign, you will speed it up. There will be no entertainment all year round.

Li Aizhen

This life lasted for 22 years, and Li Aizhen changed from a young woman to a middle-aged woman.

With her help, China Semiconductor made a big step forward from scratch and gradually improved.

However, at this juncture, Li Aizhen suddenly left this big stall and decided to go to the United States for development.

At that time, China semiconductor rushed slowly, and only the back of American semiconductor could be seen.

Scientists in China are ecstatic, and are preparing to step on the gas pedal to the end, and then "drift around the corner" in front of the United States, overtaking in the corner.

As a result, at this time, the United States showed its cards to everyone and disappeared.

They invented molecular beam epitaxy technology, and with this technology, semiconductor research and development in the United States is even more powerful.

Zou Yuan, an old expert, thinks that it is impossible to win behind closed doors according to the current situation of the country.

Know yourself and know yourself, and you won't fight a hundred battles, so he proposed to send a person to study in the United States, and then return to China to display her fists and feet after she has developed 18 martial arts.

And he has a suitable candidate, that is, his favorite pupil Li Aizhen.

Experts think alike, and everyone agrees with Zou Yuan _, but they begin to play the devil's advocate for the candidate he proposed.

After all, Li Aizhen's parents are overseas Chinese in the Philippines. If she goes to America, she will stay there. Didn't China lose his wife and soldiers, and send a man to the United States for nothing?

To say the least, even if she didn't cheat, her age was there. She is 44 years old, and her learning ability is definitely not as good as that of young people.

If we can return to China in the future, everyone will be happy, and we are afraid that her head will come back empty. Isn't this a waste of time?

In this regard, they strongly opposed it and sent Li Aizhen to the United States to persuade the top leaders to think twice.

Li Aizhen also knows that if you don't go to the United States to learn something, maybe China will fall behind in the future.

She knows nothing about her abilities. Besides, after so many years, she is not only old, but her brain will never lose to others.

This kind of mood can only be understood by those who sleep next to her. In order to help Li Aizhen, the husband did not hesitate to pledge his personality.

He promised that if his wife didn't return to China, he would let them deal with him without complaint.

Li Aizhen

Of course, his words don't carry much weight, and everyone will just watch the fun when they come out.

Finally, Zou Yuan _ stood up to defend the students. He said that he had full confidence in the student's character, and she could not have second thoughts.

She won't let him down, let alone the motherland!

Zou Yuan _ pushed through the crowd, Li Aizhen was able to go abroad smoothly and was sent to Carnegie Mellon University.

There, she studied extension techniques with Professor Milnas for 26 months.

For foreign scientists, local scientists scoff, thinking that China's science and technology can't stand the big waves, and there is no need to do these useless things.

From time to time, they made a few sarcastic remarks, trying to stimulate Li Aizhen to give up early, but Li Aizhen didn't fall for it.

She pretended not to understand and continued to bury herself in the experiment. When she didn't respond, they got bored and had to hold back their anger.

It is not that she is not angry at these personal attacks, but that she has no time to be angry.

Li Aizhen

She is only 26 months old. If she wants to pack all her knowledge here, she must race against time and break one second into two.

Following Professor Milnas, Li Aizhen was an eye-opener, and even visited the legendary Bell Laboratory to see the molecular beam epitaxy technology with his own eyes.

Knowledge knows no borders, and Professor Milnas has nothing to hide. He tried his best to impart what he had learned in his life to Li Aizhen.

Professor Milnas occasionally gives her a small stove to make up lessons for her.

At that time, the outside world was colorful, but Li Aizhen's life was just a laboratory.

She even stayed in the laboratory for three months to solve a difficult problem.

Li Aizhen

When other researchers saw it, they all candidly admit defeat and had to sigh that China people were really not to be taunted.

1982, it's time for Li Aizhen to return home, and the United States is worried.

Li Aizhen's ability is obvious to all. If we put her back in China, it will be tantamount to releasing the tiger into the wild, which will do no harm to American scientific research.

They tried their best to keep Li Aizhen.

They promised that as long as Li Aizhen stayed, whatever the conditions, they would be absolutely satisfied.

Holding an annual salary of one million, living in a high-end villa and enjoying the same treatment as local scientists.

For Li Aizhen, they are sure to win. In the face of such temptation, anyone can't help but "yield" when they see it.

Unfortunately, they underestimated her patriotic feelings, and Li Aizhen didn't buy it at all.

Li Aizhen

She made it clear that although she was penniless and lacked money and housing, she preferred her motherland to herself.

If she was engaged in scientific research to make money, she could have chosen other fields to relax.

Of course, she is engaged in scientific research and really "has other plans." The plan is that the motherland can climb higher peaks with the help of scientific research.

And in this great career, she tried her best to make a stepping stone, which is enough.

1982, when the deadline came, Li Aizhen didn't cheat, so she got on the plane home as scheduled, and the United States could only watch her leave.

After returning home, Li Aizhen rolled up his sleeves and prepared to develop "molecular beam epitaxy technology" belonging to China.

As a result, the domestic equipment is not strong, which makes her research and development progress like a turtle.

Li Aizhen was unconvinced. She gave up all social activities and soaked in the laboratory, competing with the data one by one.

She firmly believes that as long as she doesn't lose heart, she can grind iron bars into needles.

She said: "Our country should have its own technology, and a group of scientists should work hard for the country, regardless of personal gains and losses."

She is willing to be a part of it, burning her own life and illuminating the way forward for the motherland.

1989, our own molecular beam epitaxy equipment was finally developed successfully.

At this time, Li Aizhen was 53 years old. Even if she was not a little girl, she still smiled like a child when the molecular beam epitaxy equipment was successfully developed.

The research and development here has just produced results, and the United States has made new moves.

From 65438 to 0995, Bell Laboratories developed the world's first quantum cascade laser, which once again set a new record in the field of semiconductor lasers.

The United States celebrated all over the country, and Li Aizhen began to lose sleep again.

She knows that now is not the time to rest, and she must catch up with the pace of the United States and pull back a city.

So she went back to the lab, squeezed her sleep time and fought day and night.

Six years later, it was the turn of the United States to open its eyes, and Li Aizhen developed a 5-8 micron band semiconductor quantum cascade laser.

At the age of 65, she broke the record of "zero breakthrough" of such lasers in Asia and helped China to make a beautiful turnaround.

Prior to this, only the United States and Europe had this technology, and it was completely unexpected that China could catch up with others.

It stands to reason that she has contributed so much to the country and naturally has an honor.

However, in a roundabout way, Li Aizhen was defeated as an academician of the Chinese Academy of Sciences for four consecutive times.

For decades, Li Aizhen single-handedly broke through the difficulties of scientific research, and even Alfred Y. Cho, the world's "six-crown academician", was deeply admired.

Alfred Y. Cho

He never stingy praise, crazy to Li Aizhen blowing rainbow fart:

"Few laboratories in the world can do it. Most of the people in these laboratories have worked in Bell Laboratories.

Li Aizhen's independent production is a great contribution of China. "

Indeed, others, Qi Xin, made concerted efforts, and their strength was broken. In many cases, Li Aizhen only had himself, and a person silently created the world out of nothing.

He has published more than 250 papers, has 2 invention patents1and won a silver award in the national invention exhibition.

Without her, China didn't know that he would have his own laboratory for molecular beam epitaxy of semiconductor microstructure materials, solid source molecular beam epitaxy and gas source molecular beam epitaxy.

However, with so many achievements, you can't get an academician of the Chinese Academy of Sciences.

Li Aizhen

As early as 1999, Li Aizhen participated in the selection of academicians of the Chinese Academy of Sciences, and the result was stuck in the referee before reaching the final.

At that time, the government required academicians under 60 to have two referees, and those over 60 to have six referees.

However, each recommender has only two recommended places. For the future, everyone generally leaves opportunities to the younger generation.

In this way, Li Aizhen couldn't find six referees, so he passed by the academician of Chinese Academy of Sciences.

In the following years, Li Aizhen, like a demon, fought and lost many times, losing four times in a row.

In 2007, when the new academician of Chinese Academy of Sciences was selected, Li Aizhen concealed his application and continued to work in the laboratory.

On New Year's Day, her classmates called her to pay New Year's greetings, but no one answered at home. After looking around, they found that Li Aizhen was still in the laboratory.

It was suggested that although it is difficult to be selected over 65 years old, she should give it a try. Maybe she will be wrongly selected.

Li Aizhen

At that time, there were even seven academicians who co-opted to recommend her for three consecutive times, but Li Aizhen felt that it was not that important whether he was selected or not.

And she doesn't want to add pressure to other academicians for personal reasons. "I always let them down, and I feel guilty."

Someone was keen for her, shouting gross, and Li Aizhen hurried out to set up a stall:

"I don't have any dissatisfaction. I only remember what the country gave me, and I never remember what the country didn't give me. "

In a short sentence, it highlights the ideological pattern of a scientist.

Although Li Aizhen was not elected to the Chinese Academy of Sciences for three transgressions and four times, it did not prevent him from becoming famous abroad.

In 2007, Li Aizhen, 7 1 year-old, was elected as a foreign academician of the National Academy of Sciences.

Li Aizhen

When she received the notice, her father didn't know who recommended her.

This move by the United States undoubtedly warmed Li Aizhen's heart.

The people who ate melons began to worry, and Li Aizhen was heartbroken. It is estimated that he will fly to America to heal.

But Li Aizhen didn't leave enough time for rumors to ferment. She immediately stood up and gave everyone a reassurance:

"I can become a foreign academician, relying on the support of the platform, project research funds and scientific research environment provided by the motherland.

I come from an overseas Chinese family, and overseas Chinese know the meaning of the word motherland best. These two words have always been in my heart.

I'm not leaving. This is my place . where am I going? "

Li Aizhen

Li Aizhen has worked for the country and the people all his life. Even if she is a nobody all her life, she has no regrets.

Compared with her own income, she sincerely hopes that the country can take more and stand higher, which is the biggest reward for her.

Even without the title of academician of the Chinese Academy of Sciences, the glory of our motherland today is indispensable to the light of Li Aizhen.

Li Aizhen is an indelible page in China's scientific research, which cannot be erased or forgotten.

May she live a long life and witness the prosperity of the motherland with the people of China! Text/Thursday
