The specific advantages, such as efficiency and the absence of dragtorque, are maintained in this process, with costs remaining relatively Iow.
而干式离合器特有的优点，如高效率和无阻力矩将继续保持下去，同时成本仍可维持在相对低的水平。

As most of the power loads of the existing merchant ships are driven by the alternating current induction motors, it is necessary to study their dragtorque mechanical characteristics.
现代民用船舶的大多数动力负载由交流异步电动机驱动，因此，对其负载阻力机械特性的研究很有必要。
