They give off a lot of heat into the atmosphere, and for some of you may understand the heat island effect in cities, where the urban areas are much more warm than the adjacent rural areas, but we also have problems that, when we lose power, we can't open a window here, and so the buildings are uninhabitable and have to be made vacant until that air conditioning system can start up again.
它们向空气排出大量的热 所以你们中的某些人能够理解城市中的热岛效应 就是城市的温度相比相比于附近的郊区和农村 的要高的多 但是我们仍然有些问题 当我们失去了能源之后 我们不能开窗 所以 这些建筑将不再适合居住 所以必须空置出来 直到空调系统重新启动
