sound coupling

As the key point of the sound reflection and sound transmission, the acoustic coupling analysis received extensive concern.

而对于声反射和声透射的研究也使得声振耦合问题得到人们的关注。

The article puts forward the innovative thought on this question, use the photoelectrical coupler to isolate coupling, utilize the fine characteristic of the photoelectrical coupler and advantage of BTL circuit's great power output, under the output power of 400W, nearly replay the sound undistortedly.

本设计采用光电耦合器隔离耦合，利用其优良特性和BTL电路大功率输出优点设计的音频功率放大器，在400W的输出功率下，几乎能不失真地重放声音。

Random Dynamic Analysis of Piezoelectric Intelligent Trusses What we did in the paper paves a sound foundation for further research on the stochastic control of the mechanical-electric coupling of piezoelectric intelligent trusses.

压电智能桁架随机动力特性研究本文的工作为进一步进行压电智能桁架机电耦合系统随机控制打下良好的基础。

The approach is sound since it removes the tight coupling between types of objects.

该方式比较合理，因为它消除了对象类型之间的紧密耦合。
