This has proven to be an annoyance to those nearby- albeit less disruptive  than the aircraft's main powerplants running.

事实证明，这对附近的人来说是一种烦恼——尽管比飞机的主要动力装置运行时的破坏性要小。

However, engineers looking at the aircraft realized that the engines' casing, rather than the size of the powerplants as a whole, was the problem.

然而，查看飞机的工程师意识到问题出在发动机外壳上，而不是整个动力装置的尺寸上。

An inability to imagine how all these things are connected, how what we burn in our powerplants and car engines pumps out carbon dioxide that goes up into the sky.

无法想象所有这些事情是如何相互关联的，我们在发电厂和汽车发动机中燃烧的东西是如何排出二氧化碳并进入天空的。

As a result, newer jets and their larger, high bypass turbofan engines  could have their spare powerplants transported in a variety of purpose-built freighters.

因此，较新的喷气式飞机及其更大的高旁通比涡轮风扇发动机可以使用各种专用货机运输备用动力装置。

This is especially worrying to governments, as infrastructure is increasingly computer-driven, like powerplants, the electrical grid, traffic lights, water treatment plants, oil refineries, air traffic control, and lots of other key systems.

这尤其令政府担心，因为基础设施越来越多地由计算机驱动，如发电厂、电网、交通信号灯、水处理厂、炼油厂、空中交通管制和许多其他关键系统。

The company also uses the 757 to test most of the  engines it produces, including the HTF series, TFE731, and TPE 331- powerplants that are used  in both military and corporate aircraft.

该公司还使用 757 测试其生产的大部分发动机，包括用于军用和公务机的 HTF 系列、TFE731 和 TPE 331 发动机。
