摘要
本文就环境温度、太阳辐射、经济状况三个外界环境因素对人类平均寿命的影响进行了统计分析和连接向量图分析。结果表明三种因素都与人均寿命相关。经济状况与寿命正相关,太阳辐射和环境温度与寿命呈现负相关。
The statistics and linked vector graph are used to study that human average l_1fespan is affected by three factors of the environmental temperature, sun-radiation and enconomic condition. Human 1ifespan correlated negatively with sun-radiation and eviron mental temporature, and positively with eco-nomic condition.
