526th Examination Institute and Uranium-235

Hearing Chang Ruiqing's request, Xu Shuzheng began to talk about business. I saw him with a stern face: "Yaoru, the old man is now a member of the Chinese Progressive Party, and it is not my business to come to Xuzhou to elect this political member, but the task assigned to me by the Progressive Party. ”

Chang Ruiqing's face turned slightly red, and the other party was referring to Sang scolding Huai and saying ziji, but in a blink of an eye, he calmed down as usual, picked up the teacup and took a sip, and replaced it with a smiling face like a spring breeze.

"The teacher is really joking, the student Zhidào teacher can't bear to leave the Beiyang lineage and fly high alone. Otherwise, with the talent of the teacher, how can the current status be above Wu Ziyu, right? He paused, changed his words and said: "But this time, the teacher does not have to be in a dilemma between the future of Beiyang and his own future, the student means that he wants to fight with the Progressive Party, and now the Kuomintang is determined to part ways with our GCD, so that the chief officials of the central organs will have to run away more than half, whether the teacher and the Progressive Party are willing to work together with us?" ”

It turned out that it was to win over the Progressive Party and the Beiyang Yu Mai!

Xu Shuzheng's expression was slightly excited, but he still tried to keep his face tight and not laugh. Except for a few people who have taken refuge in Chang Ruiqing, they have been in the wild for six or seven years. Although he said that Shime was unofficial and light, he was looking forward to the day when he could appear on the stage and become addicted to the sub-official.

But come to think of it, the shelf that should be held still has to be served.

It was a long time. Xu Shuzheng just smiled and looked at Chang Ruiqing without saying a word, and Chang Ruiqing just sipped tea silently. The room was quiet until the end. Only then did he hear Chang Laohu cough, nodded at Xu Shuzheng, and said with a smile: "Although the old man is a big idler who eats, drinks and has fun, but he has been watching the general trend of the world for a long time, and there are still people who are foolish." Brother Zheng again, the younger brother said that he didn't listen to much, the world at the moment. It's the GCD and the Kuomintang that are fighting! No matter how much it falls into the hands of the Progressive Party, the princes of the Progressive Party still want to do something, and there is only one member of the Communist Party. And it is necessary to unite the strong and strong family, otherwise this day in the opposition is really not able to survive the end......"

He really said this to Xu Shuzheng's heart, the Kuomintang took the initiative to go into the opposition because of great ambitions, and was ready to lie on the salary and try the courage for more than ten or twenty years to fight in the post-Chang Ruiqing era. But what is the Progressive Party trying to do? This party was established on the basis of the Beiyang system and the Beiyang Foundation. The backbone members are all very old. After more than ten or twenty years, he is still not in the world.

Xu Shuzheng smiled bitterly and nodded towards Chang Ruiqing: "Yaoru, the old man is also a good intention, but the support rate of Zhongg is clearly there, and with the help of the Méiyou Progressive Party, this year's election is also ten percent sure, right?" ”

Chang Ruiqing nodded, his eyes revealed a little helplessness, and said in a deep voice: "Of course you can choose." But it's hard to say whether we can do things well, and our country is very difficult to manage. ”

Xu Shuzheng was stunned. Asked rhetorically: "Zhong G is also full of talents, and Brother Yaoru is even more of a dragon and phoenix among people, can't he leave the Kuomintang?" ”

Chang Ruiqing shook his head with a smile and said: "The teacher praised it falsely, the Central G and the Kuomintang do have a lot of talents, and the state affairs have been thriving in recent years, relying on the concerted efforts of the elites of the two parties, but after the country enters the democratic constitutional government, it can no longer be used to govern the country by the party, otherwise once a party interest group is formed, it will be difficult to clean up in the future." ”

Xu Shuzheng looked at Chang Ruiqing in a daze, his eyes rolling, trying his best to ponder the meaning of Chang Ruiqing's words. After a long while, he still shook his head slightly to show his puzzlement.

Chang Ruiqing laughed and said: "The so-called political party is just a group of politicians forming a party and wanting to govern the country with the concept of ziji. ”

"Isn't this just ruling the country with the party?" Xu Shuzheng interjected.

Chang Ruiqing still shook his head: "A political party can manage the country, but it cannot replace the government, and politicians can lead the government, but they cannot turn all bureaucrats into politicians, let alone all politicians into bureaucrats, otherwise democratic constitutionalism cannot be implemented." ”

"Yaoru refers to the difference between the elector and the examiner, right?" Xu Shuzheng patted his forehead and said with a smile: "The civil official examination system exists in Yuan Gongbao's shihou. ”

Chang Ruiqing clapped his hands and smiled: "Yes, yes, it is the selection officer and the examiner...... In the past few years, the national government was a coalition of the Kuomintang and the Communist Party, and there was no distinction between shime election officials and examination officials, and most of the lower-level officials were filled by party members of the two parties. Recently, students are planning to establish a civil service examination selection body that is independent of the government and directly responsible to the Legislative Yuan and the Senate, called the Examination Yuan, and wants to ask teachers to be the president of the Central Examination Yuan. I wonder what the teacher thinks? ”

That's killing two birds with one stone!

Xu Shuzheng said in his heart: "Use an examination institute to pull the Progressive Party away from the Kuomintang, and let the relatively independent Progressive Party temporarily control the examination institute that has the power to select civil officials, so as not to be controlled by the GCD bosses, and the civil officials elected by Shihou are all GCD members." However, this also shows that Chang Ruiqing is indeed sincere in promoting democratic constitutional government in China, at least for now. ”

But Xu Shuzheng is also an old fox who has been up and down in the political arena for many years, and he was ruthlessly deceived by Chang Ruiqing again, of course he won't Chang Ruiqing say shime, he will believe shime.

Xu Shuzheng's words changed: "According to the old man, it is not good to govern the country with the party now, bureaucrats at all levels might as well use party people, they and Yaoru brother are all yiti of the same heart, with them, Yaoru's status is as safe as Mount Tai." ”

Chang Ruiqing said angrily: "It is feasible to govern the country with the party in the short term, but the price is to make the party and the bureaucracy merge into one, and turn it into a ruling machine that monopolizes power, making it impossible to implement democratic constitutionalism. Both the students and the China and G are dedicated to the country and the nation, and will never ruin the future of the country and the nation for the sake of the interests of one party and one faction. ”

Xu Shuzheng nodded: "This is a good statement, but it is a half-truth." Brother Ruguo Yaoru really wants the old man to come out and be the dean of this exam, shouldn't he be honest? Besides, there are méiyou people here, and there are shime words that can't be said? ”

Chang Ruiqing laughed lightly. said calmly: "The student's arrangement is indeed for the long-term peace and stability of the country, and of course there are some selfishness. In fact, this party was founded by the students, and the students could not understand its temperament and temperament all too well, but once it was allowed to monopolize the power of civil service appointments and completely integrate with the bureaucratic system, it would not be able to control it. ”

That sounds like some truth. Since Yaoru still recognizes me as a teacher, then I can't agree to it. It's good that our Progressive Party got the Examination Institute. Yaoru can also firmly control the party, government, and military, and the deal will be profitable for both parties. ”

Xu Shuzheng said and held up a finger, "But I have one more request." ”

"Teacher, just come."

"A single examination institute may not be able to convince the bigwigs of the Progressive Party, and it is almost the same to add a hypocritical president."

"Who does the teacher want to be president?"

"How is Old Duan Zhi?"

Chang Ruiqing nodded heavily. "Zhi Lao is highly respected. is the best candidate for the president, and the matter is decided. ”

The deal was finalized, Xu Shuzheng didn't stay for a moment, got up and arched his hand at Chang Ruiqing, and left freely, while saying: "The old man still has to go to Tianjin to discuss with Duan Zhi and Liang Rengong, so he will leave first." ”

……

"Chairman, Professor Li Yijing has arrived at the mansion. Do you want to see you now? ”

Chang Ruiqing and his father Chang Laohu sent Xu Shuzheng all the way outside the mansion before returning to Ziji's study. I saw Zeng Qi standing there with a name in his hand.

"Professor Li?" Chang Ruiqing took it

Mingtie glanced at it and said with a smile: "It turned out to be Mr. Li Zemin, please invite him in, and let Xun'er bring three cups of coffee." ”

Zeng Qi answered, turned around and left, and after a while, he led a middle-aged man with a sharp head and a slightly ugly appearance walked in.

"Mr. Zemin, come in, come in and talk." Chang Ruiqing seemed to attach great importance to this professor, and personally stood at the door of the study to welcome him in.

Zemin is the name of Professor Li, his big name is Li Fuji, a native of Wuxian County, Jiangsu, born in Shanghai in 1881, graduated from Nanyang College at the age of 20, won a scholarship to study mechanical engineering in the United Kingdom, and then went to Germany to continue his studies, engaged in spectroscopy research, has a doctorate degree in advanced physics, is the first Chinese student to study physics abroad and obtain a doctorate. At present, Dr. Li Fuji is the director of the Institute of Physics of the Academia Sinica, and is also a professor of the Department of Physics at the Central University in Nanjing.

The reason why Professor Li came all the way to Xuzhou to meet Chang Ruiqing is inseparable from his research topic in the Institute of Physics. He is now working on a very unpopular research topic, which is to study the isotope of uranium using a mass spectrometer that the British physicist Aston had just invented! Since uranium is still a chemical element of low value, it is used for other purposes than porcelain production and méiyoushime, so the big names in the international physics community are also studying the isotopes of uranium. However, the Institute of Physics of the Academia Sinica accepted the instruction to study the isotopes of uranium at the beginning of its establishment, and it was Chang Ruiqing, who was the chairman of the Military Commission at the time, who issued this instruction!

"Report to the chairman, our research has finally come to fruition!"

Unlike most of the big intellectuals of this era, Li Fuji, a talented man in Suzhou, was very willing to save his life for Wudou Mi because of the family's great financial pressure (he had nine younger siblings and a pair of parents to take care of him). He will never raise any objections to the research tasks arranged by the above, which is the main reason why he was able to squeeze out several more famous Belarusian physicists and become the director of the Institute of Physics.

"Really? Mr. Zemin, thank you so hard. When Chang Ruiqing heard the news, he immediately showed a surprised expression, took Li Fuji's hand and asked with a smile: "How many isotopes of uranium are there?" What is the natural abundance? And what is the atomic weight? ”

Hearing these three very professional questions, Li Fu was slightly stunned, and then introduced with a smile: "At present, we have discovered two natural isotopes from ordinary uranium metal, one of which has an atomic mass of about 238 and a natural abundance of about 99%; The other has an atomic mass between 234 and 235 and a natural abundance of about 1%. ”

Lee's work apparently did not lead to the ultimate success of Méiyou, who measured the precise atomic mass of uranium-238 and uranium-235. Also méiyou measured their natural abundance, and even méiyou found uranium, the third natural isotope of uranium, uranium-234. However, Chang Ruiqing felt extremely excited, and kept saying words of praise and praise.

Between words. Chang Ruiqing, Li Fuji and Zeng Qi Yijing sat down in the study, and Sun Yuexun also brought the freshly brewed coffee.

Picking up the coffee cup and taking a sip, Chang Ruiqing said again: "Okay, very good, Mr. Zemin, the work of the Institute of Physics is very good!" He turned to Zeng Qi and said, "Write it down, and give all researchers in the Institute of Physics a 10% salary increase as a reward." A one-time bonus of 50,000 Chinese dollars will be distributed by Mr. Zemin. ”

Li Fu hurriedly excused himself and said: "Chairman of the committee, these are all things we should do, it took four years. It took millions of dollars to achieve such a result, which is really a shame on the trust of the chairman. ”

"You guys are doing a great job, I'm very mǎnyi." Chang Ruiqing waved his hand and interrupted: "Mr. Zemin, in the next step, I hope that the Institute of Physics can carry out research on the large-scale separation of uranium-235. What do you think? ”

"Separate uranium-235?" Hear this request. Li Fuji was a little dumbfounded for a moment, it is one thing to use a mass spectrometer to separate a very small amount of uranium metal, but it is another thing to separate uranium-235 on a large scale, and the difficulty of the latter is many times greater than that of the former! Moreover, what is the atomic mass of this isotope of uranium, and why did Chang Ruiqing call it uranium-235?

He thought for a moment, shook his head, and said, "Chairman...... This work relies on the scientific research strength of our Institute of Physics, and I am afraid that it is done by the méiyou method. And uranium-235 is almost méiyoushime practical value, can't you invest a lot of money in research? ”

A disappointed expression flashed on Chang Ruiqing's face. Said thoughtfully: "Mr. Zemin, you don't have to worry about the funds!" There will be enough funding to fund your research. As for the method of separating uranium-235. I have an idea for you to follow. ”

"Uh, please advise the chairman." Li Fu suddenly had a black line in his head, and he slandered for a while, this Changda dictator took the wrong shime medicine? I actually pointed fingers at physics research!

"According to Mr. Zemin's research, the uranium-235 atom is about 1.3% lighter than the uranium-238 atom, so if the two atoms are in a gaseous state, the uranium-235 atom will move slightly faster than the uranium-238 atom, and the two atoms can be separated slightly. Therefore, the key to separating uranium-235 is two points: first, to find a way to vaporize uranium metal; Second, we can make a machine to separate the gasification of uranium-235 and uranium-238, even if the abundance of uranium-235 can only be increased by yidiǎn points each time, and we can obtain uranium-235 with higher abundance after repeated gasification and separation. ”

Hearing Chang Ruiqing's "gas separation method", Li Fuji's belly immediately turned into admiration, but the look on his face gradually became solemn: "The chairman's idea should be feasible in theory, but ...... However, with the current level of scientific research at the Institute of Physics, I am afraid that it is still the Méiyou method to create a device that can separate uranium-235 gas. As for finding a way to turn uranium into gas, it should be possible to find it in two or three years as long as we do it at all costs, but the equipment for separating this gas is not something we can make. ”

Chang Ruiqing touched his chin thoughtfully, "Is it not the level of domestic manufacturing?" If you need shime equipment, just import it. ”

"It's not a question of imported equipment, it's about inventing separation equipment...... Our Institute of Physics can be méiyou genius in this area. ”

Chang Ruiqing said unrelentingly: "Where is such a genius? We asked him to come over at any cost. ”

"I'm afraid not." Li Fuji shook his head and said with a wry smile: "The physics world is not the business world, money is definitely not everything, and people who fall into the eyes of money cannot be outstanding physicists." ”

"The Méiyou problem cannot be solved with money, but also by cooperation between Tongguo countries to find a solution." Chang Ruiqing seems to be determined to make a high concentration of uranium-235. "We can work with the Germans, Jinháng, who have a lot of experts in this area," he said. Next month I will be visiting Europe and I will be there in person with German Chancellor Adolf. Hitler discussed the matter. ”

"Germany should have talents in this area, but ......" Li Fu thought for a few moments, and then said: "As far as I know, the most studied in the isolation of isotopes is the British Cavendish Xu Shi Yàn Researcher Francis. Aston. He invented the mass spectrometer used to study isotopes of uranium, and in 1913 he succeeded in isolating isotopes of neon and measuring atomic mass. Ruguo can get his help to separate the uranium...... The probability of success with 235 is much higher. ”

"British?" Chang Ruiqing's mind turned quickly, Ruguo The British Empire had the atomic bomb before the Second Shijiè War, where will the history of this time and space evolve? Don't care about nàme, in short, Ziji must have an atomic bomb in his hand. Thinking of this, Chang Ruiqing said to Zeng Qi: "Mu Han, go and send a telegram to Gu Weijun and ask him to find a way to arrange for me to visit London, well, in the name of participating in the London Navy Armaments Conference."
