摘要
本文介绍一种新的通过键盘人机对话、借助IBM PC微型计算机图形显示屏幕、直观地分析正电子寿命谱的方法,并编制出了实用程序。采用解析正电子寿命谱的务指数函数模型,从最长的寿命成分开始,由长到短逐一剥除:屏幕图象随之变化,获得的寿命谱参数作为IBM PC(Professio-nal)POSITRONFIT程序进行严格的拟合计算的初始值是足够好的。
A new method was developed for analysing the positron lifetime spectra on the graphical display screen of an IBM PC. The multi-exponential function model was used and the lifetime components of the spectrum were stripped one by one from the longest to the shortest while the graphics on the display screen were changing correspondingly, The obtained initial parameters of a lifetime spectrum are efficient and good enough to be used by the IBM PC (Professional) POSITRONFIT Program as input data.
