结构光性矿物学是矿物学的一个新分支,它的任务是研究矿物(主要的透明矿物)的光学性质与其化学成份和晶体结构之间的关系。早在本世纪二十年代初期,著名的科学家尼格里就预言:“总有一天,人们能够从晶体的化学成分和结构计算出晶体的光学性质来,这是一项基础性的工作,很有意义。希望物理学家、化学家和矿物学家来个竞赛,看准先解决这个问题”。尼格里的预言算不算矿物学中的“歌德巴赫猜想”呢?我们姑且不论,但是可以肯定,这是一个十分棘手的问题。六十多 Structural phototropism is a new branch of mineralogy whose mission is to study the relationship between the optical properties of minerals, the major transparent mineral, and their chemical composition and crystal structure. As early as the early twenties of the 20th century, the famous scientist Nigel predicted: “One day, one can calculate the optical properties of crystals from the chemical composition and structure of the crystal. This is a basic work. Meaningful.I hope physicists, chemists and mineralologists come to a contest, spotted the first solution to this problem. ” Does Nigri’s predictions count as “Goldbach’s conjecture” in mineralogy? Let’s just ignore it, but it is certain that this is a very difficult issue. More than sixty
