Characteristics of carbonate gas pool and multistage gas pool formation history of Hetianhe gas field, Tarim Basin, Northwest China
Science China Press., Co. Ltd. - Tập 47 - Trang 146-152 - 2002
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...
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
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. ...
Identification of the thick-layer greigite in sediments of the South Yellow Sea and its geological significances

Rapid assessment of acid phosphatase activity in the mycorrhizosphere and in arbuscular mycorrhizal fungal hyphae
Science China Press., Co. Ltd. - - 2000
Structure characterization of melt drawn polyethylene ultrathin films

Indoor environmental quality and the prevalence of childhood asthma and rhinitis in Wuhan area of China
Science China Press., Co. Ltd. - Tập 58 - Trang 4223-4229 - 2013
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...
Relative dielectric constant from dry rocks
Science China Press., Co. Ltd. - Tập 44 - Trang 2286-2293 - 1999
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...
Biological effect of rare-earth elements on anti-oxidation enzymes in wheat under acid rain stress
Science China Press., Co. Ltd. - Tập 44 - Trang 146-149 - 1999
Based on pot-culture experiments, the biological effect of rare-earth elements
(REE) on antioxidation enzymes of wheat under acid rain stress was studied. The
results show that both acid rain and REE can affect the activity of
anti-oxidation enzymes of wheat to different extents. Under the acid rain
stress, anti-oxidation enzymes (CAT, SOD) of wheat showed single peak curve with
the decrease of pH...
Precise orbit determination for Jason-1 satellite using on-board GPS data with cm-level accuracy
Science China Press., Co. Ltd. - Tập 54 - Trang 196-202 - 2009
The joint US/French Jason-1 satellite altimeter mission, launched from the
Vandenberg Air Force Base on December 7, 2001, continues the time series of
centimeter-level ocean topography observations as the follow-on to the highly
successful T/P radar altimeter satellite. Orbit error especially the radial
orbit error is a major component in the overall budget of all altimeter
satellite missions, in ...
