電動力學講義

內容概要

　　本書精選電動力學的基本內容，以講義的形式按課堂教學順序組織成46講。內容包括矢量分析、靜電場、靜磁場、麥克斯韋方程、物質中的電磁場、電磁波的傳播、輻射理論和相對論力學等。各講內容均衡、簡練，公式推導詳細，附思考問題，突出重點，減輕閱讀困難。
　　本書重點解決課堂教學的“程序化”（將科學體系變?yōu)橹v授的時序）問題，可直接用作教師教案，組織課堂講授；在適當增加內容之后，本書可作為普通大學本科或師范院校物理系電動力學課程的教材；本書還可作為參考閱讀資料，幫助提高科技英語水平。

作者簡介

　　鐘學富，1939年生，四川新都人，畢業(yè)于四川大學物理系理論物理專門化。曾任中國科學院半導體研究所副研究員，碩士生導師。1987年赴美為訪問學者，在密蘇里大學堪薩斯城分校物理系從事固體理論研究?，F居美國。
　　單獨與合作發(fā)表中英文物理論文約30篇。主要成果包括確立半導體中一類光轉化雜質模型，經實驗證實并獲中國科學院科技成果二等獎；首次提出在晶體場計算中考慮傳導電子貢獻，此概念被用于修改穆斯堡爾效應中的電場梯度公式。另外在《中國社會科學》、《哲學研究》、《光明日報》、《自然辯證法研究》等刊物發(fā)表涉及信息論和物理學的哲學問題的論文約l0篇。近年來陸續(xù)出版《物理社會學》、《社會系統(tǒng)》、《休閑哲學》等專著，嘗試將自組織及相關理論應用于社會研究，發(fā)展社會科學的演繹理論。

章節(jié)摘錄

版權頁：插圖：The fact that a charge experiences some force from another charge impliesthat there is "something" surrounding the charge. We call it ".electric field". Itwill be explained later that the electric field （also other physical fields） maystore energy, and possess mass, momentum and angular momentum that arecharacteristic of matter. Thus the electric field should be considered as amatter. In fact, modern physics considers field and particle as two aspects ofthe same entity, although in classic theory, the field is only considered as acontinuous medium, which supports and propagates the interaction between twoobjects in space.However, Einstein went further from the classic concept of field than justto reject an old concept of action at distance. He emphasized that the field isrelated to the space and time, i.e., if no signal can propagate in "vacuum", orany interaction must propagate in some kind of field （thus the speed ofpropagation is limited）, then we can conclude that if there is no field, there willbe no space. In fact, the field is everywhere, or nowhere is absolutely empty.In this case, space （and time） is no longer a simple container of events andprocesses, but is determined and affected by the processes proceeding in it. Theidea is the foundation of modern theory of relativity.
