摘　　要：运用数学 ,从流体力学原理上分析了流体机械发生空蚀时出现的高温、高压、高浓度化学活性物质与自然界温度、气压及机械结构的关系 。From point of view of hydrdynamics the article analyzed mathematicaly the relations between phenomena,occured during cavitation erosion,such as altithermal,high-pressure,high concentrated chemic active substances with parameters of enviroment temperature and atmosphere pressure as well as mechanical construction features of machinary.Besides,methods against the cavitation erosion were postulated.
