摘　　要：理论认为处于平衡态下系统各部分间的宏观运动形式象刚体一样，本文我们把这一理论推广到有相对论性运动的系统和超流体系统，消除了原理论不适用于超流体的误解。A theorem regarding the macroscopic motion of systems states that under thermal equilibrium the only possible motions are those of a rigid body. We show that this is true even for relativistic movements of the system. However for systems like superfluids relative motion between different components can take place even while maintaining thermal equilibrium. We generalige the theorem so as to eliminate the inconsistency that the ekisting theorem contradicts this.
