摘要
本文通过定义生命线概念引出以场论方法描述人口动态发展过程。提出回溯期望寿命概念和计算方法;某年度死亡人口平均死亡年龄和期望寿命之间的数学关系式;以及生育模式和多年前出生人口之间的关系;并探讨了消除人口周期性生育高峰的控制方法。
In this paper, we define the concept of life line and present a model describing the development process of population using the methed of field theory. We also introduce the concept of reviewed life expectancy and its calculation formula. The mathematical relation between average diedages of died pople and the life expectancy in a year, and the relation between recent year's birth models and the number of people that were torn some years ago are also given.Finally, we study how to control the birth rate so as to even the cyclic peak birth rate,
