Geometrical Error due to the divergence of X-ray beam was analysed in an Ω& goniometer with stationary slit for residual stress measurement. 本文分析了准聚焦常规法应力测定中由于X射线有一定发散度造成的测量误差,并给出了修正方法。
In this article general formulas are derived which account for the influence of X-ray geometry, the nonideal adjustment of goniometer and the parameters of recording system on the centre of gravity, on the mean-square width and on the Fourier coefficients of the line profile. 本文研究X射线衍射仪的各种工作条件对干涉线纹的重心位置、均方宽度和傅里叶系数的影响,得出了普遍的公式。
This paper briefly introduced the technology progress in X-ray source, goniometer, optics, sample holders, accessories, detectors and software of polycrystal X-ray diffractometers in recent years. 简要介绍了近几年来多晶X射线衍射仪的光源、测角仪、样品台、光学系统、附件、检测器和应用软件方面的技术进展和用途扩展情况。
