立方晶系晶体在常见合金相、夹杂物中几乎占二分之一.因此,编制立方晶系电子衍射自动检索程序是十分必要的.该程序能够计算晶面间距,标定与各衍射斑点相对应的晶面指数及晶带轴指数,而且,在上述基础上还给出可能的物相及晶格类型.该程序采用BASIC语言,可在PC—1500袖珍计算机上运行. The cubic crystal system in the common alloy phase, inclusions accounted for almost half of the Therefore, the preparation of cubic crystal diffraction automatic retrieval program is necessary. The program can calculate the interplanar spacing, calibration and the corresponding diffraction spots Crystal plane index and belt axis index, and, based on the above, gives the possible phases and lattice types.The program uses the BASIC language and runs on a PC-1500 pocket computer.
