In designing schematic diagrams, it may be necessary to compromise between detail that is necessary to make the diagram self-explanatory, and simplicity that is essential for ease of reading and understanding.

A. Schematic diagram designers may make a compromise so as to add more details to make the diagram self-explanatory and keep its simplicity at the same time for ease of reading and understanding.

B. In designing schematic diagrams, it may be necessary to pay attention to both detail that is necessary to make the diagram self-explanatory, and simplicity that is essential for ease of reading and understanding.

C. Detail makes the diagram self-explanatory. Simplicity makes it easy to read and understand. It is necessary to consider both of them and make a compromise if needed when designing schematic diagrams.

An “emergency” however, almost always involves a failure that requires immediate and rapid response, such as a total powerplant failure, fire or smoke, or rapid cabin decompression.

A. 不论怎样的“危机”大多数总是会出现需要马上快速反应的故障，比如全动力故障，着火或烟雾，或者客舱的快速释压。

B. 可是一个“危急情况”几乎总伴随着故障，需要立即快速反馈，比如一个动力装置故障，着火或烟雾，或快速客舱减压。

C. 然而，“紧急情况”几乎总是涉及需要立即和快速响应的故障，如整个动力装置失效，火灾或烟雾，或座舱快速失压。

Electrical Power system is about units and components which generate, control and supply AC and/or DC electrical power for other systems, including generators and relays, inverters, batteries, etc.

A. 电源系统讲的是发电、控制和向其他系统提供交流或直流电的组件和部件，包括发电机、继电器、变流器、电瓶等。

B. The total time resets to 0 when the button is held on for two seconds.

C. The remained time resets to 0 when the button is seen down for two seconds.

Outlets along the side walls and the center of the ceiling divide the air for symmetrical supply.

A. 空气沿着侧壁和顶板中央流出，分开并同时供气。

B. 出口在侧壁边缘和顶板中央分离空气，以便全面供气。

C. 沿侧壁和顶板中央的出口将空气分开均匀供气。

The cooled air from the air cycle machine can no longer hold the quantity of water it could when it was warm. A water separator is used to remove the water from the saturated air before it is sent to the aircraft cabin. Foggy air from the ACM condenses and coalesces the mist into larger water drops in the water separator. The water collects on the sides of the separator and drains down and out of the unit, while the dry air passes through.

A. 从空气循环机出来的冷却空气与其没被冷却时比不再能承载那么多的水。水分离器被用来把水从饱和的空气中除掉，然后空气再进入座舱。来自于空气循环机的水雾装的空气在水分离器中凝结成大水滴。水在水分离器中越来越多然后排出空气循环机，而干燥的空气继续向后流。
