 電磁 標題:請問一下介電常數與電極化率的物理意義不同在哪?? 1:monkeyparty榮譽點數2點(研究所)張貼:2007-11-13 15:02:10: Permittivity介電常數 符號 ε Permittivity is a physical quantity that describes how an electric field affects and is affected by a dielectric medium, and is determined by the ability of a material to polarize in response to the field, and thereby reduce the total electric field inside the material. 單位In SI units, permittivity is measured in farads per metre (F/m). Electric susceptibility電極化率 The electric susceptibility χe of a dielectric material is a measure of how easily it polarizes in response to an electric field. This, in turn, determines the electric permittivity of the material and thus influences many other phenomena in that medium, from the capacitance of capacitors to the speed of light. electric susceptibility χe無單位是一個純量 在我做報告時~這兩個雖然是一定不一樣的~可是好像都是材料對場的極化能力~ 實在不知道該怎麼去解釋兩個名詞的差別 希望老師能幫我解惑一下~這兩個物理的意義到底差在哪邊~感謝老師 如果我問題還有不詳細的地方~請老師指導
