Characteristics of carbonate gas pool and multistage gas pool formation history of Hetianhe gas field, Tarim Basin, Northwest ChinaScience China Press., Co. Ltd. - Tập 47 - Trang 146-152 - 2002
Xinyuan Zhou, Chengzao Jia, Zhaoming Wang, Qinghua Wang, Wei Yang
Hetianhe is a big carbonate gas field which is found and demonstrated in the period of “Chinese National Ninth 5-Year Plan”. The proved reserve of Hetianhe gas field is over 600×108 m3. Its main producing layers are Carboniferous bioclastic limestone and Ordovician carbonate composed of buried hill. The former is stratified gas pool with water around its side, and the latter is massive gas pool wi...... hiện toàn bộ
Synthesis of carbon nanotube array using corona discharge plasma-enhanced chemical vapor depositionScience China Press., Co. Ltd. - Tập 48 - Trang 534-537 - 2003
Mingwei Li, Zheng Hu, Xizhang Wang, Qiang Wu, Yinong Lü, Yi Chen
A corona discharge plasma-enhanced chemical vapor deposition with the features of atmospheric pressure and low temperature has been developed to synthesize the carbon nanotube array. The array was synthesized from methane and hydrogen mixture in anodic aluminum oxide template channels in that cobalt was electrodeposited at the bottom. The characterization results by the scanning electron microscop...... hiện toàn bộ
Effects of coagulation on submerged ultrafiltration membrane fouling caused by particles and natural organic matter (NOM)Science China Press., Co. Ltd. - Tập 56 - Trang 584-590 - 2011
YongHong Li, Jun Wang, Wei Zhang, XiaoJian Zhang, Chao Chen
Natural organic matter (NOM) and particles in source water are responsible for the majority of ultrafiltration (UF) membrane fouling that occurs during drinking water treatment. This study was conducted to (1) understand the UF membrane fouling phenomena caused by NOM and turbidity-causing particles and (2) investigate the effect of coagulation pretreatment on the alleviation of membrane fouling. ...... hiện toàn bộ
High resolution stalagmite δ18O records over the past 1000 years from Dongge Cave in GuizhouScience China Press., Co. Ltd. - - 2005
He Yaoqi, Wang Yongjin, Kong Xinggong, Cheng Hai
Based on MC-ICP-MS U-series dating and stable O-isotope analysis results, a 4–5 years resolution monsoon record over the past 1000 years has been established for two stalagmites from Dongge Cave, Guizhou. The high resolution oxygen isotope record serves as a proxy for variations in rainfall of Asian southwest monsoon over the Yunnan-Guizhou Plateau. A close relation of the δ18O record with the Δ14...... hiện toàn bộ
Indoor environmental quality and the prevalence of childhood asthma and rhinitis in Wuhan area of ChinaScience China Press., Co. Ltd. - Tập 58 - Trang 4223-4229 - 2013
Ming Zhang, ESheng Zhou, Xin Ye, YueXia Sun, Jan Sundell, Xu Yang
Indoor environmental quality is suspected to be at least part of the cause of the increasing prevalence of childhood asthma and allergy. This study is part of the China, Children, Homes, Health (CCHH) project, which was designed to identify the risk factors indoors that are associated with prevalence of asthma and allergy among children in China. A cross-sectional questionnaire study was carried o...... hiện toàn bộ
Relative dielectric constant from dry rocksScience China Press., Co. Ltd. - Tập 44 - Trang 2286-2293 - 1999
Xiangyun Wang, Huadong Guo, Chao Wang, Peirong Chen, Yangshen Shi
Relative dielectric constant is an important physical factor in the theory of microwave remote sensing and electromagnetic transmission. This note reports the results of detecting relative dielectric constant from 197 rock samples. The regular pattern of the relative dielectric constant varying with microwave spectrum is revealed. The relative dielectric constants, correlated with the type, densit...... hiện toàn bộ
