摘要

在现代Ge（Li）

能谱学中，多元素复杂能谱的分析，大都以绝对光峰效率的刻度为基础，通过孤立光峰的计算和应用放射性核素衰变纲图的知识展开的。但在天然环境样品的分析中，常因大样品的自吸收，衰变平衡态的严重破坏和

分支比数据的不齐全，这种以

衰变数绝对测量为基础的分析方法远不及相对比较测定方法简便有效。但在相对比较测定方法中，一个最常遇到的麻烦手续是能谱方程的求解，在没有电子计算机的条件下，往往会影响这类方法的广泛使用。本文试图提出一种方法，以通过响应矩阵的合理重构，绕过求解方程的麻烦，直接把包含

种核素的含量计算简化成一组简便的运算公式。

Abstract

A simple analysis method of Ge (Li) complex γ-ray spectrum of a mixture containing several radioactive nuclides is described. By reconstructing the response matrix of the standard spectrum

the concentration of each component can be determined. Applying this method to the relative comparison detection

it is possible to compute the concentration very easy by manual operations or

with the aid of an electronic computer

to save much time.
