| 摘 要： | 用蒙特卡罗方法模拟计算了闪烁晶体的长度以及源到探测器之间的距离对能谱探测效率的影响，避免了实际测量时的盲目摸索。模拟结果表明：光电峰效率与闪烁晶体的长度有关，但对源到探测器的距离变化不敏感。

| Abstract: | The influences of the length of flashing crystal and of the distance betweenthe source and the spectrometer upon spectrometric efficiency are simulated by theMonte-Carlo method to avoid notarget try in real measuring. The simulation resultsshow that the efficiency of photoelectric crcst is relative to the length of flashing crys-tal, but not sensitive to the distance between the source and the spectrometer. |
