The current is called direct current , with electrons flowing along in one direction 如果电子朝一个方向运动,则电流为直流电。
Effects of changes in electron flow on the cyanide - resistant respiration in tobacco callus 改变电子流量对烟草愈伤组织抗氰呼吸的影响
In this case the potato provides phosphoric acid , which enables a chemical reaction causing electrons flow from copper to zinc 在我这个装置中,土豆提供了磷酸,磷酸通过化学反应让电子从铜逃向锌。
Conventional cells , including ones used onboard the space shuttle and in some prototype automobiles , obtain the electrons for their electron flow by pulling them off of hydrogen atoms 包括宇宙飞船和某些样品汽车所用电池在内的常规电池,都是从氢原子中取得电子,以此来获得产生电流所需的电子。
For the self - magnetic field mid with relatively simple structure , the stability of self - magnetic field generated by electron flow is obtained by adjusting the diode gap and the delay time of bipolar pulse . under the combined effect of self - magnetic field and electrical field in the diode , stable and dense anode plasma was produced 对于具有简化结构优点的自磁绝缘离子二极管,通过调节阴阳极间距保证电子流造成的自磁场稳定形成,同时控制合适的双极脉冲延迟时间,电磁场共同作用形成了稳定的稠密阳极等离子体。
