三个坐标轴都反演了,一个“真正”的矢量(就比如三个单位矢量)当然也会跟着变了。不变的必然是“赝”的。或者这么说,真矢量一定要跟着

• 叉积依赖于手征性。而手征性在空间反演或镜像反射下必然改变,关于反演有三种操作:一维反演(即镜像反射),二维反演,三维反演(即空间 -marketreflections- ♂ (412 bytes) () 12/13/2011 postreply 21:30:53

• 所谓空间反演,用应力张量做例子,就是施加的外力变为原来的等大反向。由于不是运动,不存在时间反演 -marketreflections- ♂ (5083 bytes) () 12/14/2011 postreply 05:50:55
