(三)电气工业技术电机工程是各种工程中较为年轻的一门,但近年来发展的速度,应用之广,有凌驾其他各门工程之上的趋势。20世纪有电世纪之稱,有一定理由的。电机工程之主要基础是物理学中的电磁学,这门科学在19世纪时代已大致完成。电机工程之发展几乎全在本世纪之内。19世纪以前电学之发展约有列各端:(1)1747年富蘭克林(B Franklin)首创“一流体”说而将电分为正负两种。(2)1800年伏打(A.Volta)宣佈原电池之原理,首次獲得继续存在之电流。和电导及电容之发现共为18世纪电学上的三大发现。(3)1820年奥斯特(H.C.Oersted)首次发现电磁关系。(4)安培(A.M.Ampere)作一连串有價值的实验而发现电流与磁性现象间之数量关系,由是確立了动电学。(5)法拉第(M·Faraday)在此时期发现电动机之原理。(6)1826年欧姆G.S.Ohm)宣佈了欧姆定律。(7)1831年法拉第发现感应电动原理。(8)1865年麦克斯章(J.C.Maxwell)发表其著名的“电磁場之动態理论”。(9)1887年赫兹(H.R.Hertz)宣佈能产生并检示在太空中之以太振动而具有电
(III) Electrical Industry Technology Electrical engineering is one of the younger projects in various projects. However, the speed of development and its wide application in recent years have surpassed that of other projects. There is a certain reason for the power-century in the 20th century. The main basis for electrical engineering is electromagnetism in physics, a science that was largely completed in the nineteenth century. The development of electrical engineering is almost entirely within this century. The development of electricity before the nineteenth century included about the following: (1) B Franklin first invented “a fluid” in 1747 and divided the electricity into positive and negative. (2) A.Volta announced the principle of the original battery in 1800, for the first time to obtain the current continues. And the discovery of conductance and capacitance were three major discoveries in the eighteenth century. (3) H.C.Oersted first discovered the electromagnetic relationship in 1820. (4) A.M.Ampere made a series of valuable experiments and found that the number of current and magnetic phenomena, the relationship between the establishment of the electrokinetic. (5) M. Faraday discovered the principle of the motor during this period. (6) Ohm G.S. Ohm in 1826) proclaimed Ohm’s law. (7) Faraday discovered the principle of induced electromotive force in 1831. (8) J.C.Maxwell, 1865, published his famous “Theory of Dynamic Electromagnetic Fields.” (9) H.R.Hertz, proclaimed in 1887, capable of producing and detecting etheric vibration in space with electricity
