摘要
利用微积分的基本知识,在推导出椭球体转动惯量的基础上,给出温度对椭球体转动惯量的影响.认为在一般情况下温度对一般类刚体材料的密度影响极小,可以忽略,在计算时可以考虑使用与温度无关的函数来表示密度,但在应用到工业等项目时,则需要考虑与其具体环境的变化相适应来选取函数计算.
Using the basic knowledge of differential and integral calculus, the moment of inertia of ellipsoid is deduced, and the influence of temperature on it is given. It is considered that the temperature on the general effect of the density of rigid material is minimal and it can be neglected; functions which are independent of temperature can be used to represent the density in calculating. However, when applied to industrial and other projects, when selecting function, whether it can adapt to specific changes in the environment need to be considered.
