查询词典 oxides

IGCC, which would first gasify coal then generate power with gas turbines, can reach efficiencies of 45 percent, and would emit few particulates or oxides of sulfur. IGCC could thus help China take full advantage of its plentiful coal supplies while minimizing air pollution.

该技术可先将煤气化，然后再驱动燃汽轮机，效率可达45%，也可减少粉尘和二氧化硫排放，借此中国可以最大限度利用充分的煤炭供应同时减少空气污染。
