摘要翻译：
现有的生命表法需要先计算年龄别死亡率，不仅计算步骤多且复杂，而且引入多次近似带来误差。本文将生命表的死亡概率重新定义为在某一时期出生的一群人在较晚时间的平均死亡概率。在此定义的基础上，提出了一种新的寿命表计算方法，该方法与传统的寿命表具有相同的意义。利用日本人口数据对该方法进行验证，结果表明，该方法与出生婴儿的预期寿命相吻合，最大相对差异不超过0.1%，平均相对差异不超过0.03%。本文所述生命表的理论和方法简单易懂。所需数据易于统计，计算简便，所得结果准确可靠。它应该是一个非常有应用价值的人口统计方法。

英文摘要：
The existing life table method needs to calculate the age-specific mortality first, not only has too many and complicated calculation steps, but also introduces the multiple approximation to bring error. This paper redefines the probability of death for the life table as the average probability of death of a group of people born in a certain period at a later time. Based on this definition, a new method for the life table is proposed to obtain the life expectancy, which has the same meaning to that from the traditional life table. Using the Japanese population data to verify the method, the results show that it is consistent with the life expectancy of the birth of the baby, the maximum relative difference is no more than 0.1%, and average relative difference is less than 0.03%. The theory and method of life table described in this paper are simple and easy to understand. The needed data are easy to obtained from statistics, and the calculation is easy, the results obtained are accurate and reliable. It should be a very valuable demographic method for application.
