在Noether不变变分原理的框架下，导出了两个非线性微极弹性守恒定律(Jk=0和Lk=0)，从而推广了前人关于偶应力弹性的结果。导出了线微极弹性力学的两个非守恒M型积分，并讨论了它们的值。并与相关工作进行了比较。
Two conservation laws of nonlinear micropolar elasticity (Jk = 0 and Lk = 0) are derived within the framework of the Noether theorem on invariant variational principles, thereby extending the earlier authors' results from the couple stress elasticity. Two non-conserved M-type integrals of linear micropolar elasticity are then derived and their values discussed. A comparison with related work is also given.
