摘要
本文介绍了适用于非金属的正电子湮没辐射一维角关联实验谱的图示拟合方法及其在微机IBM-PC/XT上实现的软件。软件采用了多高斯组分的数学模型,避免了非线性拟合时必须输入拟合参数初值的困难。拟合过程直观、简单、易于掌握。
This paper introduces the plot fit methods and the software used on an IBM-PC/XT mictrocomputer, in which the sums of Gausslans mathematical model are used for nonmetallic systems. The software not only avoid the difficulty of having to input the initial parameters when fitting, but also simplefies the procees for solving angular correlation spectrum.
