孙以谏研究员，1954年10月毕业于合肥工业大学（现称）地质系，早年从事煤田地质研究，1963年始，专事X一射线结晶矿物学至今。他长于将数学方法应用于造岩矿物品体结构变化的研究。1984年在全国首届X一射线结晶矿物学会上，被选为委员及造者矿物组组长，并决定将他作为国际结 Professor Sun Yi-Jian, graduated from Hefei University of Technology (now called) Department of Geology in October 1954 and engaged in coalfield geology research in his early years. From the beginning of 1963, he specialized in X-ray crystalline mineralogy. He is longer than research that applies mathematical methods to the structural changes of rock-producing minerals. In 1984, at the first X-ray crystallographic mineral society in China, he was elected as the leader of the committee and the maker of minerals and decided to treat him as an international knot
