本文就冰晶体的结构及其在静场中的电极化进行了讨论,并应用Kirkwood统计理论计算了冰的静态介电系数ε_s,T=268K时,计算值与实验值相符合。介电系数是综合反应介质内部电极化行为的一个主要的宏观物理量,概括了电极化各种微观过程,从而使我们对固体的介电性质可得到进一步的理解。
In this paper, the structure of ice crystals and their electric polarization in static field are discussed. The static dielectric coefficient ε_s of ice is calculated by Kirkwood’s statistics theory. When T = 268K, the calculated values agree well with the experimental data. Dielectric coefficient is a major macroscopic physical quantity that synthesizes the internal polarization of the reaction medium. It summarizes various micro-processes of electrodeposition so that we can get a better understanding of the dielectric properties of the solid.
