摘　　要：针对通常高纯锗探测系统的γ谱软件不能对包含正电子湮灭峰的重峰区间进行正确的拟合编写一软件 。The usual commercial softwares of γ-ray spectrum analysis could not accurately fit the multiplet region with positron annihilation peak,because the positron annihilation peak is greatly different from other peaks.This leaves a blind region in γ ray spectrum analysis.A method is proposed in the paper to solve the problem from our practice, and a software package is developed correspondingly.
