current pulse的用法和樣例：
例句
- A current pulse is sent through the coil.
有一電流脈沖送入線(xiàn)圈。 - Now a voltage can be applied to the device and no current will flow until one of the superconducting films absorbs a photon, generating quasiparticles.
我們可以先在裝置上施加電壓，不讓電流通過(guò)，直到超導體薄膜吸收光子，產(chǎn)生的準粒子跨越絕緣層而引發(fā)電流脈沖。
