to turn down the gas

Sereepisut also hopes the change would help police save energy and reduce greenhouse gas emissions by encouraging officers to turn down air conditioners at police stations, Pongsapat added.

据介绍，舍里披素警长还希望此举能减少警局办公室内空调的使用，以节省能源和减少温室气体的排放。

Turn the gas down or wait for the charcoal to become low-burning embers. (Oven roasting and baking are done at lower temperatures so fewer HCAs are likely to form.)

请把煤气关小或者直到木炭快烧完才烤(用烤箱烘烤时，温度越低，可能产生的杂环胺就越少)。
