Solar trough systems use a series of curved mirrored troughs to focus the sun's energy on a pipe filled with a heatexchangefluid (oil).
太阳能槽式系统采用了一系列的弯曲镜像槽，是集中针对于管内液体转化热能的太阳能量(石油)。

Exergy loss in an air separation unit mainly derives from the compression and expansion processes of fluid, heatexchange, rectification and throttling.
空分设备有效能损失主要存在流体的压缩与膨胀、热交换、精馏及节流减压等。
