但是，上述这些新型功率开关器件也存在一些弱点，如电压与电流的过载能力弱，当工作参数超过其安全范围是，非常容易损坏。因此给电路结构的设计与制造提出了新的要求，并且需要快速而有效的保护措施

According to a posterior source the rebuilding of the Church in Bethlehem is attributed to this emperor. This same source says that the Emperor himself was not "satisfied" with the job carried out by his architects who had pulled the Constantinian church down, damaged during the Samaritan uprising, and built in its place a new one. The Emperor found that this new church was "dark" and he even accused the architect of wasting the Empire's money. So much was his dissatisfaction that the architect was executed!

The principle of a transferring spark source and its critical components are introduced and the electroacoustic specifications of the source are also given.

介绍了用于井间地震的传输式电火花震源的工作原理及其关键部件，并给出了其电声技术参数。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。
