摘要
本文对文献所载的弹性体拉格朗日方程的推导方法作了进一步的讨论,并从欧拉方程出发,给出了另一种推导方法。
In the paper further discussed is the inferring method of Laglange equation of elastic bodies expounded in Document (1) only to give another inferring method of it, and it is inferred with the indirect method of variation principle, or from Euler equation.
