关于螺线管各分段自感和段间互感的分析

Discussion on the Self and the Mutual Inductance of the Component Parts of Solenoid

螺线管是由各分段或各单匝线圈串联而成的,某分段或某匝线圈所匝链的磁链是其自感磁链与别的线圈对其总互感磁链之和。其中自感磁链对各匝线圈来说是相等的,与线圈的具体位置无关。而线圈所获取的总的互感磁链则与该线圈的具体位置有关:线圈越靠近管子的中间,获取的互感磁链就越大;越靠向管子的两端,获取的互感磁链就越小。至于自感系数和互感系数则与相应磁链的特点一样。

Solenoid is composed in series of many small solenoids or single-turn coils.The flux linkage of one single coil is the sum of its self--inductance flux linkage and the mutual inductance flux linkage of the others.The self--inductance flux linkage is equal to each other, nothing to do with the specific location of the coil.But the mutual inductance flux linkage is different： the ability to obtain the mutual inductance flux linkage is stronger, when more close to the middle of the coil, and get more weak when closer the two ends of the tube.Self--inductance and mutual inductance have the same characteristics of the corresponding flux linkage.
