| 8. | On condition that the volume of particle is equal , the effective permittivity of penny shape particle is the biggest , that of the needle shape is second , and the spherical shape is the last . when the thicker of shell is constant and the radius of core is bigger , the effective permittivity is less . the effective permittivity will change acutely when the thicker of shell is close to the radius of core ; with the radius of core increasing , the effective permittivity of core - shell type particle will approach that of no shell type particle
在相同的形状下(如便士形和针形) ，粒子的大小对于等效介电常数没有影响；对于核壳形夹杂颗粒复合材料，当壳的厚度一定时，随着核的半径的增大，复合材料的等效介电常数越来越小；当壳的厚度和核的半径较接近的时候，复合材料的等效介电常数将会发生急剧的变化；随着核的半径的不断增大，核壳型颗粒夹杂复合材料的等效介电常数将逐渐的趋近于没有壳的夹杂颗粒复合材料的等效介电常数。 |
