基于心射投影和旋转倒易坐标系.提出了一个绘制各种投影图和衍射谱的计算机方法,导出了相应的公式,编排了计算机程序(采用BASIC语言).本法的优点是同一程序可用来绘制极射和心射投影图、X射线Laue谱、电子衍射谱等.此外,该程序还可用来绘制各种复杂图谱,如孪晶图谱、高阶电子衍射谱等.利用这些图谱可以方便、迅速地进行各种晶体分析工作,例如确定晶体的对称性、分析任意倒易截面上的结点分布、标定X射线和电子衍射谱以及研究基体和孪晶的位向关系、确定孪晶的类型等.本程序适用于任意晶系和任意参数(任意基圆半径、照相距离或仪器常数).本程序实际应用表明,其结果是令人满意的.
Based on the projection and rotation reciprocal coordinate system, a computer method for drawing various projection images and diffraction spectra is proposed, the corresponding formulas are derived, and the computer program (using BASIC language) is arranged. The advantage of this method is that the same program is available X-ray Laue spectrum, electron diffraction spectrum, etc. In addition, the program can also be used to draw a variety of complex maps, such as twinning spectra, high-order electron diffraction spectrum, etc. The use of these maps can be easily , Quickly carried out a variety of crystal analysis work, for example, to determine the symmetry of the crystal, analysis of arbitrary reciprocal cross-section of the node distribution, calibration X-ray and electron diffraction spectra and the relationship between the substrate and twin to determine the twin Type, etc. This program is suitable for any crystal system and arbitrary parameters (any base radius, distance or instrument constant.) The practical application of the program shows that the results are satisfactory.
