中文摘要：

利用提出的远离稳定线附近的原子核β-衰变寿命的指数规律理论计算公式，对N =82附近快中子过程中等待点核素的β-衰变寿命进行了理论计算，比较了所获得的计算结果与最新的理论结果和实验结果并加以讨论。研究表明，相对于理论复杂和计算时间长的微观理论计算而言，利用考虑壳效应的远离稳定线的原子核β-衰变寿命指数规律理论计算公式能较快且准确地得出快中子俘获过程（R过程）等待点核素的β-衰变寿命。这能为R过程核素合成网络计算研究提供有效可靠的重要物理输入，并对今后天体中核素的合成研究具有重要意义。

英文摘要：

Based on the exponential formula of β--decay half-lives for nuclei far from stable line, the half-lives of nuclei around N = 82 （R-process waiting point nuclei） are calculated. The results are compared with recent theoretical and experimental data. It is shown that compared with the complicated and time-consuming microscopic calculation, the exponential formula including the shell effect can give the results ofβ--decay half-lives for R-process waiting point nuclei quicker and better. The results can be used as reliable inputs for the network calculation for nuclei synthesis in cosmos.
