本文引入终寿区间成数计算出1981年贵州男女简略寿命表。并对男女死亡概率.存活概率,期望寿命分别进行了比较。结果,死亡概率除20～25岁,45～50岁组外,存活概率除55～60岁,60～65岁组外,期望寿命除1～5岁组外,各年龄组男女之间差异均有高度显著性(P<0.01)。 In this paper, the life span of Guizhou and the simple life table for men and women in 1981 is calculated by introducing the final life span number. And the probability of death of men and women, survival probability and life expectancy were compared. As a result, the probability of death was 20 to 25 years old, and that of the 45 to 50-year-old group was 55 to 60 years old, except for the 60 to 65-year-old group. The difference in life expectancy was between 1 and 5 years old for all age groups. It was highly significant (P<0.01).
