本文介绍了一种应用“数字内插和蚀峰”原理，从ＮａＩ（Ｔｌ）整体测量γ谱中自动生成连续本底的计算方法。用此模拟本底来代替测量“本底人”的本底。该方法已用ＢＡＳＩＣ和ＦＯＲＴＲＡＮ－７７语言编写出运算程序ＡＴＢＫ，分别在ＴＲＳ－８０和ＣＯＰＡＭ－ＰＣ－２８６Ｓ微机上做了运行和试验。通过自编的转换程序ＲＥＡＤ，使ＡＴＢＫ与ＮＤ－ＡＳＡＰ谱分析软件相联合，组成了一个人体测量数据自动分析系统。 In this paper, we introduce a method to automatically generate continuous background from the γ spectrum measured by NaI (Tl) using the principle of “digital interpolation and erosion”. Use this simulation background instead of measuring the background of the “background person.” The method has been written in BASIC and FORTRAN-77 language program ATBK, TRS-80 and COPAM-PC-286S were done on the computer running and testing. Through the self-made conversion program READ, ATBK and ND-ASAP spectrum analysis software combined to form a human measurement data analysis system.
