A modified peec model was introduced , in which the integral definition of vector magnetic potential and the lorentz gauge are used to expand the integral equation to derive the peec 摘要提出了一種改進(jìn)的部分元等效電路模型,它以矢量磁位的積分表達(dá)式和洛侖茲規(guī)范代替了矢量磁位和標(biāo)量電位的積分表達(dá)式,對積分方程進(jìn)行展開。
The vector magnetic potential of a system consisting a line electric current and an infinite long magnetic dielectric column is calculated with the method of separation of variables and method of images , it is pionted out that the vector magnetic potential of a system consisting a line electric current and a magnetic dielectric plane , an ideal paramagnetic column , a superconductor column , and a line electric current in homogeneous magnetic field can all be deduced from our calculation 摘要用鏡象電流法和分離變量法計(jì)算了線電流與無限長磁介質(zhì)圓柱系統(tǒng)的磁矢勢,指出線電流與無限大磁介質(zhì)分界平面、線電流與超導(dǎo)體圓柱、均勻外磁場中有磁介質(zhì)圓柱系統(tǒng)時(shí)的磁矢勢都可以由線電流與磁介質(zhì)圓柱系統(tǒng)的磁矢勢的極限情形給出。
