The mechanical force is generated through current flow in one or more windings on a magnetic core or cores , hence the term electromechanical relay.
机械力造成的刺激继电器触点的操作原则的工作。在一个或多个绕组对磁芯或核心，因此，长期的机电式继电器通过电流流动产生的机械力。
At high speed, asphaltene plugging is more serious with increase of flow rate. The damage degree of asphaltene plugging is higher in low permeability core than in high one.
在较高流速下，随速度升高，沥青所造成的孔喉堵塞更加严重，在低渗岩心中沥青堵塞引起渗透率伤害程度大于高渗透岩心。
