1·In early days, there used to be electromechanical relay of induction disk-type.

在早年，曾是感应盘式机电继电器。

2·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。

3·The Z4 was electromechanical (relay-based), supported 64 words of memory, and ran at a whopping 40hz (at 4kw of consumed power).

z 4是机电式的(继电器式)，支持64个存储字，且运行高达40hz(消耗功率为4kw)。

4·Because the functions of electromechanical devices are easily described, their performance wills ever as a basis for presenting a description of relays and relay systems in general.

由于机电型继电器的功能容易描述，这里借用对机电装置性能的说明代表对继电器和继电系统进行总体描述。
