By analysising the DO of biological floating bed system, we have built the dissolved oxygen equilibrium equation. 通过对生态浮床系统内溶解氧(DO)(DO)的来源与去向的分析,建立了适用于生态浮床系统的DO平衡方程式。
If all the dissolved oxygen is used, an anaerobic without air decomposition process occurs. 如果耗尽了溶解氧(DO),就会发生厌气性分解过程。
Advantage is taken of the reducibility of oxygen in the polarographic determination of dissolved oxygen. 在极谱测定溶解氧(DO),则利用了氧还原性这个优点。
The organic matter may partially decompose, using up the dissolved oxygen in the sediment. 这些有机物质可能部分的溶解,用尽溶解在水中沉积物中的氧气。
