汉语拼音：gǎn kàng

电路中由于存在电感对交变电流的非电阻性的阻碍作用。用符号x璴表示。x璴＝2πfl。在电感l一定时，交流电频率f越大，感抗越大，所以电感元件有阻交通直”的作用。单位为欧姆。

• The superelectrons present an inductive impedance.

  超导电子表现出一种感抗.

• When the core is displaced, the inductive reactance of the secondary coil is unbalanced.

  当铁芯移动时, 次线圈的感抗就不平衡.

• The shield return should be as short as possible to minimize inductance.

  为了减小感抗,屏蔽体的泄放路径必须尽可能地短.

• Inductance is the property of a circuit that opposes any change in steady state current circuit.

  感抗是线路中在稳定电流状态下反抗产生改变的线路性质.

• This choke must be large in value, and provides a relatively high impedance at audio frequencies.
