性别对人口寿命影响的数学模型研究

用统计学原理研究分析了性别对人口寿命的影响，建立了数学模型，并且用模型测得人口在现代生活环境下，男性人口寿命一般情况下最高达１０５岁，女性人口寿命最高达１０９岁偶而可高于这个数值．这与某些研究人口寿命的学者的观点相一致，与细胞老年学研究的结果相吻合［１］．男女性别对人口寿命的影响结果可用“男女人口基期死亡率的对数之差与男女年龄组间死亡的递增对数的平均值的比值的５倍”的数学模型来表示．

RESEARCH OF THE MATHS PATTREN OF SEX INELUENCING THE POPULATION LIFE-SPAN

In this peper, the principles of statistics are used to analyze the life-span affected by sex and set up the maths pattern. And the pattern is used to measure that under common circircumstances the life-span of the male sex is 105 yesrs and the female sex 109 years, occasionally higher than the numerical value under modern life conditons. This is in keeping with the opinions of some scholarsl who are studying the population life-sawn and also tsllies with the research of cell gerontology. The result of the human life-span affected by sex Can be expressed by the maths psttern that is 5 times of the ratio of logarithm difference of death rate of male and female during the base Period and the average value of logarithm of the death increase rate average value of lOgarithm of the death increase rate between the age gtoupe of male and femle.
