Party member, an outstanding producer in China, an outstanding leader of China Democratic League, an outstanding scientist, educator and social activist, Vice Chairman Chinese People's Political Consultative Conference, a member of the Presidium and Faculty of China Academy of Sciences, and a vice chairman of China Association for Science and Technology, died in Tokyo on the evening of 1985 12 at the age of 74. The death of Comrade Hua is a great loss to the cause of science and technology of our party and people. The people of the whole country are deeply saddened by the loss of a great scientist.

Comrade Hua19101012 was born in an urban poor family in Jintan county, Jiangsu province. 1924, he graduated from junior high school in Jintan County and entered Shanghai China Vocational School. Because of his poor family, he left school a year later and became an apprentice in the small grocery store run by his father. During this period, he taught himself mathematics in his spare time. 1929 worked as chief accountant in Jintan middle school and began to publish papers in Shanghai Science magazine. His paper "Why the solution of Su Jiaju's algebraic quintic equation can't be established" attracted the attention of Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University. 193 1 year. On the recommendation of Professor Xiong, he went to work in Tsinghua University. It took him only eight years to go to Cambridge University in England as an administrator, teaching assistant and lecturer. 1938, he was appointed as a professor of Kunming National Southwest Associated University. Under extremely difficult living conditions, he taught during the day and worked tirelessly under the vegetable oil lamp at night, and wrote the famous book "On the Base". However, under the Kuomintang rule, this masterpiece could not be published, so it had to be published abroad, and it was not officially released in China until after liberation. 1in the autumn of 946, forced by the white terror, he left the United States and successively served as a researcher at Princeton Institute for Advanced Studies and a tenured professor at the University of Illinois. 195O, in response to the call of the motherland, comrades resolutely returned to Beijing from the United States. He has served as Professor Tsinghua University, Director of the Institute of Mathematics of China Academy of Sciences, Chairman of the Chinese Mathematical Society, Member and Deputy Director of the Department of Mathematics and Physics of China Academy of Sciences, Director and Vice President of the Department of Mathematics of the University of Science and Technology of China, Director of the Institute of Applied Mathematics of China Academy of Sciences, Vice President of China Academy of Sciences, and Dean of the Institute of Optimization Methods and Economic Mathematics of China. He devoted his life to the development of science in the motherland, especially to the study of mathematics.

Comrade Hua is a contemporary self-taught master of science and a famous mathematician at home and abroad. He is the founder and pioneer of China's research on analytic number theory, canonical group, matrix geometry, automorphic function theory and multiple complex variable function theory. His famous academic paper, Theory of Functions of Multiple Complex Variables in Typical Domains, has done pioneering work in the field of mathematics and won the first prize of China Science in 1957. His research achievements have been named Fahrenheit Theorem, Brouwer-Gadang-Hua Theorem and Hua-Wang (Yuan) Method by international mathematicians. Comrade Hua left us 200 academic papers and 10 monographs in his life, 8 of which were translated and published abroad, and some of them have been included in mathematical masterpieces of this century. He also wrote more than ten popular science works. Because of his outstanding achievements in scientific research, he was elected as a foreign academician of the American Academy of Sciences, an academician of the Third World Academy of Sciences, an honorary doctor of Nancy University in France, the University of Illinois in the United States and the Chinese University of Hong Kong, and an academician of the Bavarian Academy of Sciences in the Federal Republic of Germany. His name has been recorded in the annals of internationally renowned scientists. Comrade Hua is the pride of the scientific community in China, the pride of the Chinese nation and the pride of one billion people in China.

Comrade Hua was also the earliest scientist in China who closely combined the research of mathematical theory with production practice and made great contributions. Since the late 1950s, he has stepped out of his study and classroom and entered the vast industrial and agricultural production practice. He creatively applied mathematical methods to the field of national economy, screened out the "optimization method" with the content of improving production technology and quality and the "overall planning method" with the content of dealing with production organization and management problems (referred to as "double method"), and wrote two popular science books, namely "optimization method and its supplement" and "overall planning method and its supplement" in plain language. For more than 20 years, Comrade Hua has traveled all over the country in 26 provinces, municipalities and autonomous regions to publicize the "double laws". He organized and led the broad masses of workers, peasants, soldiers and engineers and technicians to participate in the popularization of "double methods", which made the "double methods" widely popularized and even applied to the research of national key construction projects, which not only achieved remarkable economic benefits for saving energy, increasing production, reducing consumption and shortening the construction period, but also cultivated a scientific and technological team serving the national economy. Comrade Mao Zedong spoke highly of this scientific innovation of Comrade Hua. 1964 and 1965, he wrote to Comrade China twice, congratulating him on "aiming high" and "working hard, not for individuals and serving the people". "During the ten years of turmoil, when comrades in China were persecuted by the counter-revolutionary groups of Lin Biao and Jiang Qing, comrades stood up in a fearless spirit, protected comrades in China, and supported him to continue to engage in the research and promotion of' double laws'. 1982, Comrade Hu Yaobang wrote to Comrade China, fully affirming his application of mathematical theory to production practice, calling on "more comrades to take part in tackling key problems of new technologies and new processes, and push forward China's four modernizations", and * * * built the "Tower of Babel" in China.

Comrade Hua is an outstanding representative of intellectuals in China. He has gone through two different times, old and new, and changed from a patriot to a fighter. In his early years, he participated in the anti-Japanese democratic and patriotic movement led by China's * * * production party, and was a close friend of the martyrs of Li Gongpu and Wen Yiduo. 1in the spring of 946, he was invited to visit the Soviet Union and wrote "Visit to the Soviet Union in March" to express his yearning for socialism. The birth of the new China, more inspired his patriotic enthusiasm. Seeing "the dawn of the motherland", he gave up the generous treatment of tenured professors in the United States, broke through the heavy blockade and returned to the embrace of the motherland. On the ship crossing the Pacific Ocean, he wrote to his classmates studying in the United States: "In order to choose the truth, we should go back;" For the sake of the nation, we should go back; In order to serve the people, we should also go back ... and fight for the construction and development of our great motherland! "He is patriotic, fearless and pure, and he is praised by the broad masses of the people and all patriotic intellectuals. In the long-term scientific research work, especially in the process of combining scientific research with production practice, Comrade Hua studied Marxism-Leninism and Mao Zedong Thought hard, improved his ideological and political consciousness, and strongly urged China to join the * * * production party and fight for the cause of * * *. During the ten years of turmoil, although he was in adversity, he did not shake his faith in the party. Since bringing order out of chaos, I have sincerely supported the line, principles and policies of the Party since the Third Plenary Session of the Eleventh Central Committee, and I am in a good mood and refreshed. 1979, under the cordial care of the CPC Central Committee, he gloriously joined the China * * * Production Party and realized his long-cherished wish. In his reply to Comrade Deng's congratulatory message, he wrote excitedly: "The sea doesn't donate a drop of water, and the red furnace cultivates sand into gold, and the four turn to the top soldiers." "Cross knife regardless of the bald head, the horse nearly young and strong, not in the name of party member. "This fully shows the firm belief and noble sentiment of a fighter. He regards joining the Party as a new starting point for his way forward and demands himself more strictly. Despite his old age and infirmity, he finally recalled the manuscript stolen during the ten-year catastrophe with amazing perseverance and made new development, and wrote the Mathematical Theory of Large-scale Optimization of Planned Economy, which not only described the previous research results completely, but also made new progress.

Comrade Hua is also a famous social activist. He is a member of the 1st to 6th the NPC Standing Committee, vice chairman of the 6th China People's Political Consultative Conference and vice chairman of China Democratic League. He cares about national affairs, actively participates in national political life, and makes suggestions for economic construction and the development of science, culture and education. He took an active part in NLD activities and made important contributions to the development of NLD work, the expansion of the patriotic United front and the reunification of the motherland. In recent years, he has visited abroad many times, made many friends, and engaged in the great unity of intellectuals in China. He often used the poem "There is a bosom friend overseas, and heaven remains our neighbourhood" to inspire overseas Chinese to make contributions to the four modernizations of the motherland, the third cooperation of the country and the great cause of the reunification of the motherland, and made valuable contributions to strengthening friendly cooperation and scientific and cultural exchanges between China and people of other countries. Comrade Hua is a great mathematician who promotes the progress of China's scientific career and a model for a generation of China people to become self-taught. Comrade Hua lived a glorious life and fought for the people. In order to revitalize China and human progress, he devoted his life to the scientific cause of the people. The road he took was, first of all, a bright road for China intellectuals to advance in this century. Comrade Hua has added new wealth to the scientific and cultural treasures of China and the world, and left us a rich spiritual legacy. He is an example to our people, especially the younger generation. Comrade Hua is self-taught, diligent and realistic, brave in pioneering and forging ahead. He went to school for nine years and only had a junior high school diploma. Eventually he became an outstanding scientist at home and abroad, and his success depended entirely on hard self-study. Even in his later years, his prestige and position in the academic circles were already high, and he still insisted on reading and writing. He has never been superstitious about genius, thinking that "genius comes from accumulation, and cleverness lies in diligence". As a warning to himself, he put forward the famous saying that "the old tree is easy to empty, the old man is easy to loose, and the scientific way is to keep it empty and loose, and I am willing to be loyal to it all my life." Shortly before his death, he wrote: "You don't know wisdom until you are white, and you should work hard for the future. Diligence is a good medicine, and one point of hard work is a talent. " This is the secret of Comrade Hua's success.

Comrade Hua loves the motherland, the party and serving the people wholeheartedly. He often said: "Science has no national boundaries, but scientists have their own motherland." His enterprise's love for the socialist motherland and his love for the Party are organically linked. As long as the Party needs it, he is willing to cook soup and make a fire. He took "serving the people wholeheartedly" as his motto and used it as a yardstick to measure all right and wrong. He dissolved his thoughts, behaviors, pursuits and ideals in the highest interests of the motherland, the party and the people, and was worthy of being a noble producer. Comrade Hua carefully supported the younger generation to grow sturdily. He attaches great importance to discovering and recommending outstanding talents. He is the initiator and organizer of the mathematics competition for middle school students in New China, guiding teenagers to love science from childhood, entering the field of mathematics research, and supporting them to become a new generation of mathematicians in China. Comrade Hua worked hard for the four modernizations to the last breath. Ten years ago, Comrade Hua suffered from myocardial infarction for the first time. After he was discharged from the hospital, he left such a poem: "A strong man died of cold, and I don't care about some scars. Attack the Millennium old demon, strive for a hundred generations of new styles, and throw yourself generously! " /kloc-in the autumn of 0/982, he was overworked because he wrote day and night. He suffered a second myocardial infarction and was admitted to the hospital. He earnestly asked his assistants to stick to the direction of serving the national economy and promote the development of applied mathematics in solving practical problems. On June 3rd this year, he led a group of middle-aged business backbones to Japan for academic exchange. /kloc-on the afternoon of 0/2, he died of a heart attack while giving an academic report to the Japanese mathematics community. Our beloved Comrade Hua gave his precious life for the four modernizations of the motherland and for strengthening the friendly cooperation between the Chinese and Japanese people and scientific and technological personnel, realized the grand oath that "the greatest hope is to work until the last moment of life" and fought for the cause of * * *. Comrade Hua said goodbye to us forever, and the Chinese spirit will exist forever.
