文摘

插图:



A vector quantity has both a magnitudeI and a direction in space. We shallbe concerned with two- and three-dimensional spaces only, but vectors may bedefined in n-dimensional space in more advanced applications. Force, velocity,acceleration, and a straight line from the positive to the negative terminal of astorage battery are examples of vectors. Each quantity is characterized by both amagnitude and a direction.
We shall be mostly concerned with scalar and vector fields. A field (scalaror vector) may be defined mathematically as some function of that vector whichconnects an arbitrary .0rigin to a general point in space. We usually find itpossible to associate some physical effect with a field, such as the force on acompass needle in the earth's magnetic field, or the movement of smoke particlesin the field defined by the vector velocity of air in some region of space. Note thatthe field concept invariably is related to a region. Some quantity is defined atevery point in a region. Both scalar fields and vector fields exist. The temperaturethroughout the bowl of soup and the density at any point in the earth areexamples of scalar fields. The gravitational and magnetic fields of the earth,the voltage gradient in a cable, and the temperature gradient. in a soldering-iron tip are examples of vector fields. The value of a field varies in generalwith both position and time.

序言

本书是著名的McGraw-Hill教育出版公司于2001年在美国纽约出版的《工程电磁场》教科书,适用于工科本科第一学期课程,也很适用于我国高等学校进行“工程电磁场”课程的双语教学。原书(1958年第1版)作者是美国普渡(Purdue)大学的Hayt教授,经几次改版,现在第6版增加了合作作者Buck教授。本书自第1版自起一直是美国在电磁场方面的畅销书。全书行文生动流畅,十分精练,叙述概念非常准确。作者在序言中就说明了其写书的原则是注重物理概念的理解和解题能力的培养,所以写得很有特色,主要体现在以下几点:
1.建立新概念,提出新问题、新内容,做到由浅入深,循序渐进,从正反两方面分析比较。例如讲到用流线描绘点电荷的电场分布时,用了四个图加以比较讨论,使初学者印象深刻;又如讲矢量分析一章时,先说明在研究电磁场的初级课程中,不用矢量分析理论也可以,只是存在缺点和局限性,再提出用矢量分析的必要性和优点,然后进入主题,这样可提高学生的学习兴趣和紧迫感。
2.讲解新的物理结构模型时,先从广泛意义上日常普遍接触观察到的现象入手。例如讲解电容时,先说明只要两个导体中间隔以介质,有电位差,导体上就会有电荷储存,就产生了电容作用,体现了电容的本性。进而再讲述有特殊结构的电容器和电容的计算方法及储能公式等。这样从感性认识出发,由表及里,达到理论高度,符合认识规律。
