一、請將下列英文譯為中文：（20 分） Significant Features. Electric propulsion drives offer a number of important advantages which, in certain applications, more than overcome the inherently higher first cost, increased weight and space, and the higher transmission losses of such systems. The ease and convenience by which propeller speed and direction are controllable in an electric drive are among its foremost features. This control can be effected from a number of remote locations, and thus put directly in the hands of the vessel navigator or operator. The electric control system lends itself to any desired speed of response and to the incorporation of time constants or limits, so that the machinery is not subjected to abusive or dangerous operation. The electrical connection between the generator and the propulsion motor provides a freedom of installation arrangement not offered in a mechanical drive system. The prime mover and its generator can be located wherever desired and constitute a mechanically independent engine-generator set. The propulsion generator sets are usable as a source of power for other functions when not being used for propulsion. Cargo pumping, fire-fighting, cargo-refrigerating, and dredge- pump driving are illustrative of such supplemental service.
