Catadioptric systems

The reflection and refraction of traveling wave are quite complicated at the sheath-crossing point of high voltage power cable, due to its remarkably noncontinuous surge impedance.

高压电缆的金属护套交叉互联导致行波在多个波阻抗不连续点产生了复杂的折反射行为,这对高压电缆线路的行波故障测距产生很大的影响。

The optical center and properties of lens mirror combinations are discussed according to the theory of the equivalent optical systems.

根据等效光学系统理论 ,讨论折反系统的光心及其性

First of all, the problems of the reflection and transmission of acoustic waves at the interface between fluid and rock with elastic-plastic deformations and between rocks in the presence of elastic-.

首先,研究了有静态弹性和弹塑性形变的流-固和固-固界面的弹性波折、反射问题。
