有效电感 meaning in Chinese

effective inductance

3 . the distance of metal wire and ground is smaller , the effective permeability leff , quality factor q and resonance frequency srf is also smaller ; the coil turns increases leff will increase , the q value and resonance frequency srf will drop ; the line width increases leff will drop , resonance frequency srf will increase and the q value is nearly invariable ; the via size , the pad layer size and thickness is little effect the effective permeability leff and resonance frequency srf but seriously influence q value
3金属导线离地的距离越小,有效电感值leff 、品质因子q 、自谐振频率srf也越小;线圈圈数增加, leff增加, q值和自谐振频率srf下降;线宽增加, leff下降自谐振频率增大q值几乎不变;通孔大小、覆盖层的大小及厚度对有效电感值leff和自谐振频率srf没有多大影响,但对q值影响较大。
