普適弛豫定律

前言

Fifty years ago, I was sitting in a class at Jiaotong University inShanghai,  China  taking  a  course  called  " DIELECTRICPHYSICS" lectured by the late Professor Chen Jidan. I was oneof the thirty students sitting in his class taking the course. Thiswas the first time DIELECTRIC study was introduced toChinese Universities. Since then, dielectric study became one ofthe major concerns of the science and technology community ofChina in developing its electrical and electronic engineering.Fifty years past, thousands of students, graduate students,professors, scientists and engineers have been engaged in thestudies and applications of dielectrics in this country. In the pastfifty years, the Xi'an Jiaotong University, Shanghai JiaotongUniversity, Electronic Science and Technological University,Shandong   University,   Zhongshan   University,   SichuanUniversity, Nanjing University,  Tongji University and theShanghai Institute of Ceramics, the Beijing Institute of Physicsof the Chinese Academy of Sciences were heavily involved indielectric studies and gave their various contributions to thedevelopment of dielectric study in China.  Now,  China isprobably one of the most important countries in dielectric studiesamong the list of the ex Soviet Union and the United Kingdom.Late  Professor  Chen  was  the  pioneer  and  founder  ofDIELECTRIC studies in China. The staidness, sureness andsolemnness of his academic attitude are the invaluable treasureof the Chinese dielectric community. I would like to take the chance of writing this preface to pay my sincere respect to the late Professor Chen.

章節(jié)摘錄

DIELECTRICS AND INSULATORSThe use of electrical insulation is as old as the science and technologyof electrical phenomena; it goes back at least a century and a half,while the recognition of specifically electrostatic manifestations ofelectrification goes back to antiquity. Systematic investigations ofdielectric properties may be traced back to the 1870's.The accumulated experimental and theoretical material is vast andfrom an early stage on it was possible to discern two essentiallycomplementary approaches to this wide-ranging subject- the studyand development of insulators and of dielectrics. In this classifi-cation, insulators are materials used to prevent the flow of currentwhere it is not desired, especially in the context of electrical andelectronic engineering, and the principal interest in them lies inachieving the lowest possible electrical conduction coupled with themaximum resistance to destructive breakdown in high electric fields.Other factors such as long life, low cost, chemical inertness and the ability to withstand elevated temperatures may be added to the long list of technical specifications which must be met by modern insulating materials working sometimes under extreme external stresses. It is understandable that engineers and materials scientists searching for insulating materials suitable for specific applications were less concerned with the detailed physical mechanisms gov- erning the behaviour of these materials, provided that their char- acterisation in terms of clearly defined parameters could be achieved reliably and simply. This order of priorities remains true to this day and the chief emphasis in electrical insulation science falls on the synthesis of materials and their characterisation. By contrast with the insulation aspect, dielectric phenomena are at once more general and more fundamental - after all, insulators are dielectrics - and are concerned more intimately with the micro- scopic mechanisms of dielectric polarisation and include, especially, the transient behaviour under time-varying electric fields.
