摘要

为了测量钢筋混凝土结构、金属围护结构等建筑物的电磁屏蔽效果，研制了一种便携式测量装置。本文介绍了它的工作原理、结构和参数。为了提高系统的性能，采用了光纤系统。用Matlab编写了测量程序。从一次时域测量中可以获得广泛的频率特性。最后给出了一个实例。

Time domain measure system of the magnetic shielding effectiveness

In order to measure the magnetic shielding effectiveness of buildings such as reinforced concrete construction, metal enclosure, a portable measurement device was developed. Its principle, structure and parameters are introduced in this paper. In order to improve performance the optic fiber system was used in the system. The measure program was written in Matlab. A wide range of frequency properties can be obtained from one time-domain measurement. Finally an example is presented.
