（８２）~Ｓｅ的２νββ衰变寿命是双β衰变中第一个直接测量到的实验结果．本文利用双核子机制以及简化的壳模型波函数计算给出了８２Ｓｅ的２νββ衰变寿命的理论值，适当地调整壳模型计算中的参量，可获得与实验符合较好的理论半寿命。
The 2νββ decay lifetime of (82) ~ Se is the first direct measured double-β decay. In this paper, the theoretical value of the 2νββ decay life of 82Se is given by using the dual-nucleon mechanism and the simplified shell model wave function. The theoretical half-life in good agreement with the experiment can be obtained by properly adjusting the parameters in the shell model calculation.
