伽玛常数是核物探许多参数中一个最基本的参数。对于诸如平衡系数,射气系数,质量吸收系数……,人们不仅在理论及实践上进行了相当程度的探讨,而且还给出了规范性的测量方法。可是,至今我们尚未看到有关伽玛常数进行的研究工作,这就导致取值混乱及存在某些原则性问题。由于伽玛常数的特殊地位,如果我们不去解决这些问题(例如针对性的取值 The gamma constant is one of the most basic parameters in many parameters of nuclear exploration. For such as the balance coefficient, the radio coefficient, the mass absorption coefficient ..., people not only in theory and practice conducted a considerable degree of discussion, but also gives a normative measurement method. However, so far we have not seen any research on gamma constants, which leads to confusion of values ​​and some problems of principle. Due to the special position of the gamma constant, if we do not solve these problems (for example, the targeted value
