众所周知,反射率是不透明矿物一个很重要的光学常数,在各家的鉴定表中都被置于首要地位。由于它在不透明矿物鉴定工作中如此重要,因而岩矿鉴定人员对显微光度仪的需求特别迫切。虽然国外生产的显
It is well-known that reflectivity is a very important optical constant for opaque minerals and has been given the highest priority in the individual identification tables. Because of its importance in the identification of opaque minerals, the needs of rock miners for the spectro-photon are particularly pressing. Although significant foreign production
