| 1. | Time reversal t is not unitary .
时间反演T不是幺正的。 |
| 2. | Time reversal invariance is a very useful symmetry in subatomic physics .
时间反演不变性在亚原子物理中仍然是一种很有用的对称性。 |
| 3. | Time reversal t is not unitary
时间反演t不是幺正的。 |
| 4. | Time reversal principle and its application to passive communication were introduced
分析了时反法的理论基础，并对其用于浅海被动通信进行了仿真研究。 |
| 5. | Time reversal is a unique self - focusing technique for spatial and temporal focusing of sound in unknown environments
摘要时反法是一种新颖的自适应聚焦技术，它可以使声信号在未知环境下实现时空聚焦。 |
| 6. | In astrophysics , a white hole is a postulated celestial body that spews out matter , in other words an anti - black hole , or the time reversal of a black hole
在天体物理学中，白洞是一个假定向外喷吐物质的天体,换句话说就是一个反黑洞,或时间逆向流动的洞。 |
| 7. | This ruins the time reversal symmetry , so if you look at past history you don ' t get the white hole part of the solution but rather a black hole forming towards the end of the stellar collapse
这就破坏了时间反演对称性，因此如果你顺着倒流的时光往前看，你将看不到这个解中所描述的白洞，而是看到黑洞变回坍塌中的恒星。 |
