摘　　要：人口生命表作为人口统计学的一项重要分析技术,简明而直观的反映了人口数目因死亡而变动的过程,而死亡概率是生命表中一个最重要的元素,它的精确程度将直接影响着生命表质量的高低。大部分的文献都认为指数死亡概率比伐尔死亡概率精确,本文的观点恰好相反,我们认为,伐尔死亡概率比指数死亡概率要精确。The population life tables, an important analytic technique of demography, intuitively reflect theprocess of change of population number because of death. Probability of death is the most significantelement for the life tables. Its accuracy has a direct influence on the quality of the life tables. Quite a fewdocuments are known as that Exponential Dead Probability is more accurate than Farlle DeadProbability. But this paper depicts an entirely different point of view： Farlle Dead Probability is moreaccurate than Exponential Dead Probability.
