摘要
本文把阳光辐射对混凝土坝温度的影响问题抽象为偏微分方程初边值问题,并证明了其广义解的存在性。
The present paper presents the initial and boundary value problems of partial differen- fial equations from the influence of radiation of sunlight on the temper ature of concrete dams.It proves the existence of the solution in the wider sense,and provides the theoretical basis of mathe- matics and the approximate method for solving the problem of the influence on the temperature.
