工程電磁場

前言

本書是著名的McGraw-Hill教育出版公司于2001年在美國紐約出版的《工程電磁場》教科書，適用于工科本科第一學(xué)期課程，也很適用于我國高等學(xué)校進(jìn)行“工程電磁場”課程的雙語教學(xué)。原書（1958年第1版）作者是美國普渡（Purdue）大學(xué)的Hayt教授，經(jīng)幾次改版，現(xiàn)在第6版增加了合作作者Buck教授。本書自第1版自起一直是美國在電磁場方面的暢銷書。全書行文生動(dòng)流暢，十分精練，敘述概念非常準(zhǔn)確。作者在序言中就說明了其寫書的原則是注重物理概念的理解和解題能力的培養(yǎng)，所以寫得很有特色，主要體現(xiàn)在以下幾點(diǎn)：1.建立新概念，提出新問題、新內(nèi)容，做到由淺入深，循序漸進(jìn)，從正反兩方面分析比較。例如講到用流線描繪點(diǎn)電荷的電場分布時(shí)，用了四個(gè)圖加以比較討論，使初學(xué)者印象深刻；又如講矢量分析一章時(shí)，先說明在研究電磁場的初級(jí)課程中，不用矢量分析理論也可以，只是存在缺點(diǎn)和局限性，再提出用矢量分析的必要性和優(yōu)點(diǎn)，然后進(jìn)入主題，這樣可提高學(xué)生的學(xué)習(xí)興趣和緊迫感。2.講解新的物理結(jié)構(gòu)模型時(shí)，先從廣泛意義上日常普遍接觸觀察到的現(xiàn)象入手。例如講解電容時(shí)，先說明只要兩個(gè)導(dǎo)體中間隔以介質(zhì)，有電位差，導(dǎo)體上就會(huì)有電荷儲(chǔ)存，就產(chǎn)生了電容作用，體現(xiàn)了電容的本性。進(jìn)而再講述有特殊結(jié)構(gòu)的電容器和電容的計(jì)算方法及儲(chǔ)能公式等。這樣從感性認(rèn)識(shí)出發(fā)，由表及里，達(dá)到理論高度，符合認(rèn)識(shí)規(guī)律。

章節(jié)摘錄

插圖：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.
