摘要: 本文简要地讨论人口系统稳定性中临界妇女生育率的离散和连续两种计算公式的关系, 并对连续型给出了一种较好的离散化计算公式.用具体数学说明几种公式在计算中的差异, 从而看出从离散方程导出的离散公式在应用时较为直接方便,与实际更为贴切.Abstract: This paper discusses briefly the relationship between formulas of both discrete and continuous expressions for critical fertility rates of women in stability theory of population systems. The better one of discrete formulas derived from continuous equations is given. The differences of formulas are shown with numerical results. Thus we can see that the discrete formula derived from discrete state equations is rather direct and available for applications.
