time-reversal invariance

This paper discusses the nonconservation of parity in the weak interactions and explains this point by giving examples. It also discusses the problem of the violation of CP invariance in the decay of K0 mesons and that of the breakdown of the invariance under the time-reversal transformation.

本文首先讨论在弱相互作用中宇称不守恒问题，介绍若干个宇称违背的例子，进而讨论在K~o介于衰变中CP违背和时间反演不变性破坏的问题。

The time invariance is a crucial property of systems in the course of Signals and Systems.

在“信号与系统”课程中,时不变性是系统的重要性质.

An affordance is invariance for environment and it is a relation among space, time and action.

某个可供性是环境的不变量，是关于空间、时间和行动之间的一种联系。

Invariance under translation in time leads to conservation of energy.

在时间平移下的不变性导致能量守恒.

Details are as follows: ( 1) The content has described the basic theories and methods of VSP three-component polarization analysis and has reviewed the traditional VSP polarization analysis. ( 2) The superiority-inferiority of time-shift and time-invariance has been compared and analyzed.

具体内容有：（1）阐述了VSP三分量偏振分析的基本理论方法，对常规的VSP偏振分析方法进行了回顾总结。（2）对比分析了时变和时不变偏振分析的优缺点。

Second, to describe, for the first time in a book, recent results of Smirnov in conformal invariance.

来描述，这在一本书的第一时间，最近的结果斯米尔诺夫在形不变性。
