本文介绍的简略寿命表计算程序(CASIOfx-3600P)采用了1981年WHO推荐使用的美籍教授蒋庆琅的公式,并以1982年邛崃县男性简略寿命表计算为例,说明了实际操作步骤。通过已知各年龄组(x～岁)的实际人口数(_nP_x)和实际死亡数(nDx)算出年龄死亡率(_nM_x=nDx/nPx)(我国一般取_1a_0=0.15,_4a_1=0.4,5～岁组及以后年龄组_na_x=0.5),在1_0=100000的条件下,即可用该程序算出死亡概率_nq_x、生存人年数_nL_x并据此算出各年龄组预期寿命。
The simplified life table calculation program (CASIOfx-3600P) introduced in this paper adopts the formula of the American professor Jiang Qingyu recommended by the WHO in 1981. Taking the calculation of the simple life table of the male in Shexian County in 1982 as an example, the practical operation steps are explained. The age mortality rate (_nM_x=nDx/nPx) is calculated from the actual population (_nP_x) and the actual death count (nDx) of each age group (x to year old) (China generally takes _1a_0=0.15, _4a_1=0.4,5 The age group and later age group _na_x=0.5), under the condition of 1_0=100000, can use this program to calculate the death probability_nq_x, the number of years of existence_nL_x and calculate the life expectancy of each age group accordingly.
