Biode-gradability of organic additives used for offshore drilling wes measured by using method of integrated oxygen consumption and biodegradable law, and the mechanisms were studied, while the intrinsic relation between biod.

The results suggeste that abiotic oxygen consumption of reservoirs at 70℃ is mainly the low-temperature oxidation of crude oil.

The consumption of dissolved oxygen mainly included bio-consumption, degrading of organic compound and the consumption of sediment, of which the sediment consume above 80 percent of the dissolved oxygen consumption.

By experimental study of Yangzhou ancient canal's silt samples,this paper ob- tains the following results:the relationship between silt oxygen consumption rate and flow ve- locity;the compute model of silt oxygen consumption rate in calm water and silt oxygen con- sumed material releasing rate;the simulation result of the running ship's influence on silt oxy- gen consumption.

Changes in hemodynamics and oxygen consumption in elderly patients undergoing upper abdominal surgery under epidural anesthesia combined with general inhalation anesthesia;

The observations of the effects of intraperitoneal CO_2 insufflation on respiration and oxygen consumption by using DATEX Ultima monitor;

OBJECTIVE The balance between systemic oxygen delivery /oxygen consumption was analysed and correlated to factors and changes during cardiopulmonary bypass.
