执行“蕴含”布尔操作的一种（逻辑）门电路。

A gate that performs the Boolean operation of implication.

正如在第二章里所描述的，操作员通过这个命令，能把一个物理设备分配给一个逻辑设备名。

The operator can assign a physical device to a logical device name through this command, as describe in the second chapter.

布尔代数中的一种运算，它同时对两个二进制数字进行如下操作：如果一个数或二个数为1，则结果为1；如果二个数均为零，则结果为零。它的逻辑算符是OR

An operation performed in Boolean algebra on two binary digits simultaneously in a way that the result is one if either one or both digits are a one, or zero if both digits are zero. The logic operator is the OR operator.

一种实现逻辑“或”算法的门电路或机械器件。当在其多通道输入端有一个或多个输入时就产生一个输出信号。“或”门实现逻辑“或操作”的功能。同ORelement。

An electrical gate or mechanical device which implements the logical OR operator. An output signal occurs whenever there are one or more inputs on a multichannel input. An OR gate performs the function of the logical"inclusive OR operation".
