Power cables have many advantages and occupy less land. Generally, it is buried in soil or laid in indoor, ditch and tunnel. The insulation distance between lines is small. High reliability. It is less affected by climatic conditions and surrounding environment, stable transmission performance and high reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less maintenance. It's less likely to shock.

传统的使用习惯上，示波器的接地方式就是那根长长的接地夹线。这种接地方式，确实是一种简单方便的接地方式，但是却并不是一种严谨的、准确的接地方式。接地夹线示意图由于地夹线比较长，其会形成一个寄生电感Lgnd，随着夹线的增长，这个电感也会增大，而这个回路电感会和示波器探头的输入电容Cin产生谐振。这就导致示波器的幅频特性变得不平坦，导致测量不准确。下图为使用接地夹时的等效电路。接地夹线等效电路图下图为用该等效电路仿真出的频谱特性曲线：频谱特性曲线图可以看出，在60MHz以上的频率，幅度已经产生了超过3dB的过冲，而到达100M左右时，过冲到大幅度。

如果你有一定PLC理论基础的，或者是本科毕业甚至研究生毕业系统学习过PLC全部基础知识还不能操作PLC的同志。别人说一些专业名词你大概能听明白怎么回事。这个时候你就更有基础，节省时间先把那些基础书籍与找个PLC自己动手编个小程序，哪怕是一个起保停电路，下载到PLC中运行一下。这个阶段要解决的问题是：结果与理论是否一致，如何巩固专业理论，熟悉PLC外围线路如何不同方法怎么接，plc编程软件程序有多少种不同编程思路，怎么使用实现同一种功能目标。
