Although it is the earliest-issued thesis on the study of computer radiation safety, people paid little attention. In 1983, a Swedish scientist published a pamphlet named Compromising Computer, in which the radiation leakageof computer was mentioned once again. In 1985, a Netherlandish scholar named Ike issued his study report on electromagnetic radiation from video display units of computers at the Third Conference on Computer Communication Safety Protection. At the same time he demonstrated how to use a black and whiteTV set to receive signals from a computer with radiation leakage. His report caused a great reverberation in the world. From then on people began to treat this problem seriously.

这是最早发表的研究计算机辐射安全的论文，但当时没有引起人们的注意。1983年，瑞典的一位科学家发表了一本名叫《泄密的计算机》的小册子，其中再次提到计算机的辐射泄漏问题。1985年，荷兰学者艾克在第三届计算机通信安全防护大会上，公开发表了他的有关计算机视频显示单元电磁辐射的研究报告，同时在现场作了用一台黑白电视机接收计算机辐射泄漏信号的演示。

电路 2 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。
