| 摘 要： | 以γ射线为例,通过做思想实验和推导计算的方法,分别讨论了三种不同效应———光电效应、康普顿效应和电子对效应中γ射线吸收的频率限,并利用其中的矛盾深入探讨了这三种效应之间的关系,总结出了统一处理光吸收问题的方法和一些结论。

| Abstract: | Taking gamma ray as an example,the authors discussed frequency limits of three different gamma ray absorptions: photoelectric effect,Compton effect and electron pair effect.Some thought experiments and several calculations were carried out for the porpuse of finding the relationship of these three effects and some antinomies of the frequency limits.In conclusion,the method was summarized for dealing with gamma ray absorption. |
