寿命与遗传及环境的关系

The Relationship of Human Life-span Heredity and Environment

该文根据现代遗传学，分子生物学，医用生物学及其它有关学科的知识，对影响人类寿命的种种因素概括为“遗传因素”和“环境因素”两大类。并认为人类寿命主要是由遗传因素决定的，但是，在后天的工作和生活中，只有充分注意环境因素，遗传决定的寿命才能充分表达。

In the light of knowlege of Modern Genetics,Molecular Biology,Medical Biology and other relevant science,the paper analyses some factors affecting human life-span,and clarrifies them into two groups:“hereditary factors” and“environmental factors”.The authors think that human life-span is mainly determined by heredity, and that only when environmenal factors are considered fully in life,human life-span determined by heredity can be fully expressed.
