Mr. Feng Duan, a famous physicist, metal and crystal material scientist and educator in China, academician of China Academy of Sciences, the first dean of the Graduate School of Nanjing University and professor of physics, died in Nanjing on 19: 4 15 at the age of 98. Academician Feng Duan promoted the development of nano-materials science in China, made important contributions to the development of physics and materials science in China, and won many national natural science awards.

First, brilliant achievements in physics. He has been engaged in scientific research for 78 years and won many awards, including the National Natural Science Award, the National Science and Technology Progress Award and the Chen Jiageng Prize in Mathematical Science. His most outstanding contribution is in condensed matter physics, and he is one of the pioneers in the study of crystal defects in China. Later, the textbook Metal Physics was published, which became the first monograph in this field in China and was widely used by universities and research institutes. Later, he devoted himself to the field of nano-research, and wrote two heavy books, Introduction to Materials Science and New Theory of Condensed Matter Physics.

Second, brilliant achievements in art. He is excellent not only in scientific research, but also in artistic writing. He can write good poems, especially poems for his wife. In fact, he was born in a scholarly family since he was a child. Who is his father Feng Zupei? The last scholar? . Under the influence of his father, his artistic cells have been greatly improved. Whenever it comes to his wife's wedding anniversary, he will write a poem for his wife, which makes people envious and shows that they love each other very much.

1990 on our wedding anniversary, Feng Duan wrote many poems in Beijing, one of which was? Looking for a bosom friend, looking for a beautiful woman to unify. I'm glad that Qingqing has a good eye for pure jade and pure crystal. ?

In the spring of 2005, Mr. and Mrs. Feng Duan visited Tianmu Lake, and Feng Duan improvised "Celebrating the Golden Wedding": Sauvignon Blanc in April, cherry blossoms weeping willows. Fifty years later, swimming hand in hand, your head is still as affectionate as it was then?

20 15 April 1, about Feng Duan and Chen? Diamond wedding? The couple collaborated on a song "Ode to Diamonds", which contained several lines: In the Spring and Autumn Period of 1960s, they loved each other deeply, and they held hands to tide over the difficulties. Now the white hair grows old together and lasts forever. ?

The death of Academician Feng is undoubtedly a great loss in the field of physics in China. May Mr. Feng be immortal, and your footprints will be pursued by our descendants.
