【摘要】 微型计算机系统是由各分系统、部件组成的，因此，作为电磁设备的微型计算机，其电磁辐射是通过这些分系统和部件共同作用的结果。现有的文献大多是将微机作为一个整体来研究其辐射特性；本文通过对微机系统各组成部分信号的产生和流向进行分析，寻找各分系统、各部件可能产生的辐射。在此基础上，对各部件的电磁辐射进行实际的测量，再将理论分析与实际测量结果进行比较、分析、处理，从而对微机各部件产生电磁辐射的特性和机理有较深入的了解。 另外我们通过理论分析与试验，对降低微机电磁泄漏的方法进行了一些探讨，并取得较明显的效果。更多还原

【Abstract】 The Personal Computer System is a kind of electromagnetic equipment. And it is composed of many independent components and subsystems. Thus, the electromagnetic radiation from the computer system is contributed by the components and subsystems together. So far, in many existing documents, the computer is considered as a whole for it’s radiating characteristics. But we study the computer’s radiating characteristics by analyzing the circuit configuration of its differential constituted parts. In my thesis, the study starts from analyzing different kinds of signal’s production and flowing paths in the computer system. On the basis of this, the possible radiating sources of the computer’s differential parts are predicted and measured. Furthermore, we compare the theoretical analyzing results with measured ones. As a result, we get more knowledge about the electromagnetic radiating mechanism of different components in computer system.In addition, some effort on experiments and theoretical analysis is made to decrease the magnitude of electromagnetic radiation from computer. It shows that the effect of radiation is obviously reduced.更多还原
