光电峰的FWHM与射线能量之比的百分数表示什么()。光电峰的FWHM(半高宽)与射线能量之比的百分数是用于衡量闪烁探测器区分不同能量射线能力的一个指标,这个指标就是能量分辨率的定义,所以B选项正确。
annealing temperature, the more FWHM reducing rate is, meaning that the change of microstructure is greater at higher temperature. Fig 1. The variation of FWHM for the surface of GCr15 steel after TSP with annealing time during annealing at different temperature. ...
