With the aid of an invariable parameter K~*, the invariability of M and N related to parameters r and s respectively was found as function of K~*, thus, the invariable parameter method for calculating the mosaic size and microdistortion was proposed. This method may be not only simplified the calculation by the conventional Rezak method but also overcome the complexity of not yet solved Cauchy square and other five methods. The diagram and formula of M_1 and N_1 given as a function of K~* would ease tc resolve the physical broadening into m and n. It seems to be quite available for on-line or off-line calculation. 收稿日期: 1986-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 白埃民 何崇智 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/137 1 Klug, H.P.; Alexander, L.E., X-Ray Diffraction Procedures for Polycrystalline anti Amorphous Materials, 2nd ed., Wiley, New York, 1974, p. 618． 2 Jones, F.W., Proc.
