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
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
Second generation YBCO coated conductors: A reviewScience China Press., Co. Ltd. - Tập 49 - Trang 2435-2439 - 2004
Yanwei Ma, Liye Xiao
The advance in first generation Bi-2223 HTS wire has enabled the demonstration
of superconducting power cables, magnetic energy-storage devices, transformers,
fault current limiters and motors. However, the low irreversibility field (H*)
prevents application of Bi-2223 at 77 K in any significant field. Worldwide
activities are therefore, focused on developing a second-generation HTS
technology bas... hiện toàn bộ
