3 . the solution for the distribution of potential internal 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 the included angle value of polarization vector and the external field vector and we have discussed the result and hold that the direction of polarization field strength with that of the external field don �� t always strict antiparallel
