焊接结构在使用过程中,会发生应力腐蚀、电化腐蚀等问题,还会作为接地、避雷等设施的载体,研究它作为电介质的行为特性,有利于深入了解钢结构发生电学失效的机理。而等效电路是研究电介质的常用方法,文章总结了电介质中的基本等效电路及常用电路,研究等效电路的频谱特性,并建立了介质中不同极化与等效电路的对应关系。可以应用本文的结论,进一步阐释金属结构在电学作用下的宏观特性。

In the process of using welded structure, stress corrosion can occur, such as electrochemical corrosion problems, but also as a carrier of grounding and lightning protection facilities, research it acts as a dielectric properties, and insight into mechanism of steel structure of the electrical failure occurs.Commonly used method of equivalent circuit is the study of dielectric, this article summarizes the basic equivalent circuit and commonly used in dielectric circuit, study on equivalent circuit of frequency characteristics, and the establishment of different polarization corresponds to the equiva- lent circuit in media relations.You can apply the conclusions of this article, to further explain macroscopic properties of metal structures subjected to electr...
