1.
Then the peak-to-total ratios in the NaI(Tl) detector to various γ-ray were calculated, and the results are fit in well with the experiment data.
利用能峰展宽参数计算不同能量γ射线的峰总比,结果与实验值相符,验证该计算方法可用于NaI(Tl)探测γ能谱的模拟。
2.
The source, such as point, plane and disc were measured in several source-detector distances for the research on invariability of the peak-to-total ratio, and the curve of peak-to-total ratio was presented.
测定了点源、面源和盘状源在距HPGe探测器表面不同距离上的峰总比,研究了探测器的峰总比随样品形状和测量几何条件的变化规律,验证了同一探测器不同测量条件下峰总比基本不变的特性,给出了所使用HPGe γ谱仪的峰总比曲线。
