上个世纪90年代以来,世界范围内信息产业革命风起云涌,大大推动了包括传统工业在内的全球技术革命,从根本上改变了传统工业"徒手操作、粗大笨重、尘毒危害、振动噪声"等落后的状况,以自动化、信息化、机械化、密闭化和遥控化逐步取而代之,从而从本质上改善了劳动条件,减少了各种危害因素对劳动者在作业过程中安全和健康的危害. 相似文献

主持人语 :包括各类人员、各种物资在内的应急"资源",是企业在突发情况下开展应急处置工作的基础。但在实践中,一些企业的应急"资源"配备并不合理,比如有些方面的"资源"可能存在"过剩",有些方面的"资源"却又存在"短缺",有些"资源"可能完全"无用武之地",而有些必要"资源"又完全没有配备,这显然会严重影响应急处置工作的开展。 相似文献

Unregulated emissions from a diesel engine equipped with vanadium-based
urea-SCR catalyst 总被引:1,自引:1,他引:0
The present work is aimed at the study of number-size distribution of particles,volatile organic compounds(VOCs),and carbonyl compounds(CC) or carbonyls emitted from a 4-cylinder turbocharged diesel engine equipped with a vanadium-based urea selective catalytic reduction catalyst.The engine was run on an electric dynamometer in accordance with the European steady-state cycle.Pollutants were analyzed using an electric low pressure impactor,a gas chromatograph/mass spectrometer,and a high performance liquid chromatography system for the number-size distribution of particles,VOCs,and CC emissions,respectively.Experimental results revealed that total number of particles were decreased,and their number-size distributions were moved from smaller sizes to larger sizes in the presence of the catalyst.The VOCs were greatly reduced downstream of the catalyst.There was a strong correlation between the conversion of styrene and ethyl benzene.The conversion rate of benzene increased with increase of catalyst temperature.Formaldehyde,acetaldehyde,acrolein and acetone were significantly reduced,resulting in a remarkable abatement in carbonyls with the use of the vanadium-based urea-SCR system. 相似文献
