非稳定解 meaning in English

unsteady solution

Then , use galerkin principle to put the stability equation in order for the special function the mathieu standard form , and utilize the boundary of the mathieu solves ’ steady area and unsteady area , namely special relationships of and , draw the discrimination equation of losing the magnetoelastic steady critical state
然后，应用galerkin原理将稳定性方程整理为特殊函数马丢方程的标准形式，并利用马丢方程的稳定解区域与非稳定解区域的分界，即系数和的本征值关系得出了磁弹性最低失稳临界状态的判别方程。
