晶闸管开关电路在低压电器电寿命试验中的应用与分析

采用晶闸管开关电路对较大过程试验电流进行无触点式非物理分断,替代机械开关实现了试验电路中陪试品的功能,极大地降低了产品试验站的硬件投入和人力维护成本,提高了测试效率。分析采用软件滤波的方式实现了波形的优化处理,解决了实际中的问题。最后通过试验,验证了该改造陪试电路的可行性和相应软件滤波方法的正确性。

Notes on Multi-linear Variable Separation Approach

The multi-linear variable separation approach method is very useful to solve (2+1)-dimensional integrable systems. In this letter, we extend this method to solve (1+1)-dimensional Boiti system, (2+1)-dimensional Burgers system, (2+1)-dimensional breaking soliton system, and (2+1)-dimensional Maccari system. Some new exact solutions are obtained and the universal formula obtained from many (2+1)-dimensional systems is extended or modified.
