shell type core 中文意思是什麼
shell type core
解釋
殼型鐵心-
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
在相同的形狀下（如便士形和針形） ，粒子的大小對于等效介電常數沒有影響；對于核殼形夾雜顆粒復合材料，當殼的厚度一定時，隨著核的半徑的增大，復合材料的等效介電常數越來越小；當殼的厚度和核的半徑較接近的時候，復合材料的等效介電常數將會發生急劇的變化；隨著核的半徑的不斷增大，核殼型顆粒夾雜復合材料的等效介電常數將逐漸的趨近於沒有殼的夾雜顆粒復合材料的等效介電常數。 -
