This text passes to the research of the gamma line drift regulation of Multichannel Gamma ray Spectrometer measurement, and does a flood of experiment put forward concrete dissolve gamma line drift influence of the data handles method
Through solve a least square problem
） Abstract： Because of the influence between environment temperature and instrument high-pressure variety etc
factor, It is appear the gamma line drift in the measurement of Multichannel Gamma ray Spectrometer
The same energy of gamma line measured in different time appears in different position
The gamma line drift is usually ineluctable
The serious gamma line drift measures to the outdoors the spot regardless still analytic diagraph in sample in indoors the result brings serious error margin
It’s demand proceed the data and overcomes the influence of the gamma line drift
成功的将最小二乘算法应用到比活度的求取、零点漂移和增益漂移的求取中
严重的谱线漂移无论是对室外现场测量还是室内样品分析的测量结果带来严重误差
