摘要
采用椭球坐标系经推导严格地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 ,以及极化场强方向与外电场方向之间夹角大小的表达式 ,并通过编制程序计算作出了该夹角的大小随外电场方向的变化关系图 ,还分析了此夹角和椭球体的三个半轴之间的关系 ,指出了某些文献的不妥之处 .
The solution for the distribution of potential internal and external the dielectric ellipsoid has been obtained by means of ellipsoidal coordinates, and has obtainted the expression of the polarization field strength in the dielectric ellipsoid, calculated the included angle value of polarization vector and the external field vector, making programe to compute to get the relation shetch between them and have discussed the result and hold that some document′s conclusion is not right.
