要：随着越来越多的电气、电子系统出现并应用在我们的生活中，我们也便越来越频繁的被迫使着去面对一个问题――电磁干扰。由于各类电气、电子系统在工作的同时不可避免的会产生电磁骚扰，因此怎样才能使得在同一空间内工作的电气、电子系统能达到电磁兼容以实现良好工作便成为了我们不得不认真研究的一个课题。With the rapid development of electrical and electronic products in context with the living, we are obligated to face up a very serious problem engendered from the extensive uses of those products, - “The Electromagnetic interference”. It occurs and impacts on each other when various electrical and electronic systems working. Therefore, the solution about how to achieve the integrated electromagnetic compatibility in one spatial area becomes a subject for us to research and discuss potentially.
