| 摘 要： | 采用椭球坐标系经推导求出了均匀电场中电介质椭球内和椭球外的电势分布，获得了椭球体内极化场强的数学表达式，并计算了极化场强方向与外电场方向的夹角，明确指出文献1]中关于椭球体内极化场强方向与外电场方向严格相反的结论，必须附加一定条件才能成立．

| Abstract: | By means of ellipsoidal coordinates and with strict derivation, this paper has obtained the solution for the distribution of potential internal and external the dielectric elipsoid, and also has obtainted the solution of the polarization field strength in the dielectric ellipsoid, we have calculated the angle value of polarization vector with the external field and firmly hold that the document1]'s conclusion:the direction of polarization field strength with that of the external field holds strict anti parallel must be supplemented with additive certain conditions. |
