The temperature and 压力影响 pressure have different effect on absorption cross-section. Using 0 引言 deuterium as a continuum near UV light source, we have studied the absorption characteristic of SO2 from absolute 中国的火电在能源结构中约占总装机容量 pressure 0.01MPa to 0.4MPa with a resolution 0.5nm(FWHM) 75%，每年耗煤5亿吨左右。在今后相当长的时期内， under temperature 300K and 403K. The SO2 absorption 我国仍将以煤炭发电为主，火电厂SO 、烟尘等排 cross-section will decrease with the total pressure increasing 2 when SO2 partial pressure is constant. The SO2 absorption 放量均居全国各行业首位，排放的SO 占“两控区”
