The liquified petroleum gas is the domestic and foreign recognition clean energy, also is one of national key promotion important substitution clean energy.Because the liquified petroleum gas system has the craft to be simple, the disposable investment is small, the time limit for a project short...
3，By taking such issues into account China can set an example to other biomass-rich nations and combine sustainable rural development with reductions in greenhouse gas emissions.通过解决这些问题，中国可以为其它生物质资源丰富的国家树立一个榜样，把农村可持续发展和温室气体减排结合起来。
The core 8 and the plate 13 are fastened together by a hollow rivet 12. When used in an electro - magnetically operated valve in a gas safety device, the assembly is secured to a support 16 by rolling portions 17 thereof over the edges of the plate 13.LUIGI DE STEFANI,PIER...
As an example of Chuandong Gas Field, this study get an improved application by converting formation pressure-time curve to water head-time curve on the basis of trial injection test and groundwater flow theory, that is, Bernoulli equation and Theis equation for unsteady groundwater flow. 展开...
and to a lesser extent, natural gas) are associated with emissions of particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and a variety of organic contaminants such as mercury and volatile organic compounds (VOCs)... KV Stackelberg - 《Encyclopedia of Environmental Health》 ...
aFor example, in the cause of greenhouse effect gases, (CH4) growth rate second only to carbon dioxide and water vapour, it had an important role on changing the atmospheric structure. Z.B. in der Ursache der Gewächshauseffektgas-, (CH4) Wachstumsrate an zweiter Stelle nur zum Kohlendio...
Nomatter how language develops, it is a symbol of a nation. 英国英语和美国英语在词汇上有所不同。例如,美式英语单词“subway"gas"" pants" 和“apartment"在英式英语中是"underground"petrol""trousers"和“flat"。每个国家都有自己的语言,但在我看来,语言的变化与不同国家的政治制度和文明的多样性有关,...
CH$_2$S was produced by low pressure thermolysis of a gas flow of C$_3$H$_5$SCH$_3$/Ar (560$^irc$ C) and CH$_3$SCl/Ar (1150$^irc$ C) in the entrance of the multipath white cell (optical path length 32 m). At a total pressure of 0.15 mbar, 40 scans were recorded ...
The carbonate rock formations have obvious dual media characteristics, fracture development and good physical conditions, which are the main seepage channels and storage spaces for gas after the reconstruction of underground gas storage. The carbonate st
