a其次,他们禁止人们随意向河流中排放生活垃圾。去使水中氧量增多,长出危害水质的水生物。 Next, they forbid the people at will to discharge life trash to the rivers in.Makes in the water the oxygen quantity to increase, is long the harm water quality the water biology. [translate] ...
This provides sufficient resident time of the water in a quiet zone to permit the generated oxygen gas to transition into the dissolved state prior to reaching the top of the resident time housing. An outlet is provided at the top of the resident time housing. Treated water having a high ...

A float is located in the tank to selectively control the introduction of compressed air into the tank by activation of the air compressor when the water level reaches a preselected high point as the water in the tank absorbs oxygen from the air pocket above the water level. The float also...
Free Ways to Increase Your Oxygen Level With oxygen being the third most abundant element in the universe, after hydrogen and helium, and oxygen is the most abundant element by mass in the Earth’s crust (20.8%), you would think we would have plenty of oxygen available....
These results strongly infer that highland Phyllotis have evolved a metabolic strategy to economize oxygen when performing energy-demanding tasks at altitude. This study provides compelling evidence of adjustments in fuel use as an adaptation to high-altitude hypoxia in mammals. 展开 关键词:...
This invention deals with an apparatus and method for the industrial production of a new form of hydrogen, oxygen and other gases possessing a higher specific density and a greater energy content that its corresponding conventional gas before processing the convention gas through the apparatus.收藏...
