1、The principle of simulation of the statistics counting of radioactive nuclear decay based on the rejection method is presented, and the simulation is implemented with TC programming.───本文从原理上分析了采用舍选法进行随机抽样，得到符合放射性衰变统计规律的模拟计数值，并用TC进行了编程实现；
2、Factors influencing precise measurement of relative peak counting rates are discussed in time-series measurements over a dynamic range of 1000-fold radioactive intensities (10 half-lives).───对放射性强度跨越1000倍动态范围(10个半衰期)的跟踪测量中影响相对峰计数率精确测定的因素进行了讨论。
3、A radioactive source is used to bombard the rocks surrounding the wellbore with gamma rays. By counting the backscattered gamma rays, the density of the subsurface rock can be computed.───利用放射性源的伽马射线轰击井眼周围的岩石，通过对反散射伽马射线计数，可以计算出地下岩石的密度。
