Alternating current is different from direct current in that it constantly changes its direct of flow.
交流电与直流电的不同之处在于交流电不断地改变其电流流动方向。

If you have a fairly reliable and constant, high-volume flow of water then an Alternating Current (AC) supply is a possibility.
如果你有一个相当可靠的水和持续不断的，体积流量然后一交流电流(AC)电源的可能性。

A new computational scheme was developed to solve a three-dimensional model of a periodic flow reversal reactor by ADI alternating direction implicit method.
