Because of the low thermal conductivity of coal and the slow rateofdistillation, coking is a slow process.
因为煤的导热性低、蒸馏的速度慢，所以炼焦的过程较慢。

The effects of operation conditions , such as the temperature and flow rateof solution and the width of air-gap on membrane permeability were studied by air-gap membrane distillation.
利用气隙式膜蒸馏实验对料液温度、流率及气隙宽度等操作条件对膜渗透性能的影响进行了测试和分析。
