上海有色金属研究所有一台D/max-ⅢA型x光衍射仪,内有一块MC6800微机模板可对仪器实现几种固定的程序控制,并输出2θ四种形式的数据。通过与上海科大合作,研制了接口硬件,使D/max-3A衍射仪与TRS-80微机联用,可将D/max-3A的输出数据存入TRS-80微机的磁盘,并能被BASIC程序调用和处理。该所采用取向分布函数法计算立方晶系材料的结构。此法根据东北工学院梁志德三维取向分布函数法的理论,并结合具体的实验条件和微机计算方法,将算得的极点密度与求晶面百分数的方法相结合。就铝材而言,传统方法仅能测七个反射面的极点密度,而
Shanghai Institute of Nonferrous Metals has a D / max-ⅢA x-ray diffraction instrument, which has a MC6800 computer template can be achieved on the instrument several fixed program control, and output 2θ four forms of data. Through the cooperation with Shanghai University of Science and Technology, the interface hardware was developed so that the output data of D / max-3A can be stored in the disk of TRS-80 microcomputer by using D / max-3A diffractometer and TRS-80 microcomputer, Program calls and processing. The orientation distribution function method is used to calculate the structure of the cubic system material. According to the theory of three-dimensional orientation distribution function method by Liang Zhide of Northeast Institute of Technology, this method combines the calculated pole density with the method of calculating the percentage of crystal plane by combining with the specific experimental conditions and computer calculation method. In the case of aluminum, the conventional method can only measure the pole density of seven reflecting surfaces
