摘要: 介绍了计算弛豫时间的数据拟合原理、拟合误差估计及拟合优度的统计度量,在此基础上,用NDP一FORTRAN386语言自编了拟合程序SIMFIT,该程序能提供不同的拟合方法和多种拟合函数供使用,并能显示拟合曲线和拟合误差,特别适用多指数弛豫的数据拟合。

关键词: 弛豫时间, 拟合, 误差估计, NDP-FORTRAN386

Abstract: The data fit theory of relaxation time measurement is intriduced in this paper.The formulas of error estimates and statistical measure of goodness-of-fit are given.On the basis of these,a program SIMFIT is written in NDP-FORTRAN 386 language.Different fitting methods and fitting functions can be used in this program.The fit curve and fit error can be displayed on the screen.

Key words: Relaxation time, Fit, Error estimates, NDP-FORTRAN 386
