摘要

介绍了一种测定合成蓝宝石主介电常数的机械作用法。它是基于对悬浮在均匀电场中的球体所经历的耦合的测量。当频率为50 Hz时,测量值为[垂直]= 79±05,[平行]= 65±04,这些值与其他方法得到的值相当。该方法一般适用于各向异性晶体,并建议稍加修改,可用于相应的电导率测定。

The measurement of the principal dielectric constants of sapphire by a mechanical action method
A new mechanical action method for the determination of the principal dielectric constants of synthetic sapphire is described. It is based on measurements of the couple experienced by a sphere of the material suspended in a uniform electric field. The values were found to be [perpendicular] = 79 ± 05 and [parallel] = 65 ± 04 when measured at a frequency of 50 Hz, and these values compare favourably with those obtained by other methods. The method may be applied to anisotropic crystals in general, and it is suggested that with slight modification it may be used for the corresponding electrical conductivity determinations.
