碰撞，匝链电路中由于磁通量而造成电伏减少的单位，等于穿过一载流线圈的磁通量与线圈匝数之积 A measure of the induced voltage in a circuit caused by a magnetic flux and equal to the flux times the number of turns in the coil that surrounds it.
韦伯磁通量的国际单位，等于当磁通量在一秒钟内被统一地减弱为零时在它联接的一圈电路内产生一伏特电动势时的磁通量 The SI unit of magnetic flux equal to the magnetic flux that in linking a circuit of one turn produces in it an electromotive force of one volt as it is uniformly reduced to zero within one second.
光度计用来测量光的性质、尤其是光的强度和通量的仪器 An instrument for measuring a property of light, especially luminous intensity or flux.
