摘　　要：符合法和计数相加法是级联衰变核素活度的两种测量方法。文章分析了两种方法的原理、联系和区别。在此基础上,提出了相加法和直接计数相加法,并指出,相加法和符合法在数学上是等价的,直接计数相加法和计数相加法是等价的。The coincidence method and count-summing method were normally applied to determine the activity for β-γ nuclides. The principles, relation and difference of two methods were discussed in the paper. The summing method and the direct count-summing method were also brought forward.
