摘要: 介绍粉末谱数值计算的基本手续。推导了更具综合性和普适性的数学形式,作为计算机拟谱的前提。陈述程序中的若干考虑:所有跃迁吸收合成总谱时的权重处理,四极矩作用的涨落对单线展宽有贡献,而且这种效应对中心跃迁及伴线的影响各不相同。强调一套描述共振吸收的参数获得是基于对全谱型的最佳拟合以及在场强变化情况下各特征峰移动行为的符合。

Abstract: The basic procedure for the digital calculations of the po-vier pattern has been introduced. As a premise of computer simulations a mathematic formula' tion withmore synthesis and universality has been deduced. Following considerations are accepted in our program the weight treatment of the combination of absorptions of all transitions resulting in the total spectrum, the fluctuation of the quadrupole interaction gives rise to a broadening of single lines, this effect delivers different effects to the central transition and satellites. It is emphasized that a set of parameters describing the resonance absorptions are obtained by an optimum fit with the all-over pattern and the coincidence of those shifting behaviours of characteristic peaks as the external field changing.
