22、 1.4 mhz 的频带，经过深入的研究，IE实在股数相同的情况下，所用的李兹线由多股46 AWG的细线组成时，效果最好。具体一点说，假定有两条同样是 660股的李兹线：第一条用660条46 AWG的导线组成；第二条用660条38 AWG的导线组成。虽然第二条线粗得多，它的总表面积比第一条线大很多，但是用在不同频带的时候，效果不一样：用在850 khz - 1.4 mhz频带的电路里时，第一条线的效果比第二条线的效果更好。用在50 khz - 100 khz 频带的电路里时，第二条线的效果比第一条线的效果更好。这是实验的结果，原因是很复杂的。 不同频率的电流在通过同一种多股导线的时候，产生的电

23、磁场不同， 当然会影响到各种电磁参数而有不同的结果。以上资料是生产李兹线的公司实验的结果，在理论上怎样解释这种现象，我还没有找到答案。有趣的是：李兹线的集肤效应并非单纯与导线的总表面积有关，而是与组成李兹线的股线粗细、通 过的电流的频率也有关系。从第4帖所举的例子看：两条同样是 660股的李兹线，一条用660条46 AWG的导线组成；第 二条用660条38 AWG的导线组成。第二条线粗得多，它的总表面积比第一条线大很多，但是这 两条线对不同频率的电流效果不一样。提供这些资料只是觉得有趣。46 AWG的李兹线是很难买得到的，我们也不要走火入魔。除非有意 深入研究，否则在可能的条件下，以自己能够得
