...、力学,宇宙是如何随时间演化的 "力学--无论经典力学还是量子力学--的宏愿就是要告诉我们宇宙是如何随 时间演化(time evolution)的。因此,力学必须描述行星围绕太阳的运动,以 及电子围绕原子核的运动。

After a long time evolution,the system finally reaches a stable state at which the magnetization and the equal time spin-pair correlation are periodic oscillating functions with the equal period as the external field.
我们发现,系统经过一个驰豫过程而趋于稳态,在稳态时磁化强度和等时对关联的时间演化曲线是与外场等周期的周期函数。
