用于对放射性矿石进行取样的γ能谱仪,应该具有很高的稳定性。通常所采用的稳定方法是,用不同的基准信号源,对谱仪的放大电路进行全部稳定或部分稳定。在轻便谱仪中,基准信号源必须满足下述基本要
Γ spectrometer used for sampling radioactive ore should have high stability. The usual method of stabilization is to use a different reference signal source to fully or partially stabilize the amplifier’s amplifier circuit. In light spectrometer, the reference signal source must meet the following basic requirements
