有效电流是指把一个直流电流和一个非直流电流分别通入两个相同的电阻器件，如果在相同时间内它们产生的热量相等，那么就把直流电流的值作为非直流电流的有效值。
对行之有效的进程之一涉及拆除的部分飞机和淹没在一个特别温和的解决方案，通过它的电流是通过坦克的碎片。
One of the proven processes involves partially dismantling the aircraft and submerging the pieces in tanks of a special solution through which a mild electric current is passed.
该系统产生的电流为直流电，所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。
The system generates a direct current, so using it to power DC devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.
因此尽管电流刺激法在试验室的效果不错，科学家仍在寻找其它有效方法。
So while that works in a lab and it works well, they are looking at other ways of doing it.
