脫氧作用

Episodes of deoxygenation were found in 13 cases during monitoring. 13例病例在監(jiān)測過程中出現(xiàn)發(fā)作性腦氧合降低。

The said purifier mainly is used for final deoxygenation of molten steel. 該凈化劑主要在鋼液終脫氧時使用。

Deoxygenation yield of reaction was high up to 84% by radical mechanism. 通過自由基反應歷程以30%25過氧化氫高效率地去除了底物結(jié)構(gòu)中的羥基,收率達到84%25。

The mechanism of reductive deoxygenation of pentose and the modified procedure were discussed in detail. 并重點討論了五碳糖還原脫氧合成法的機理和改進的方法。

Algal blooms, heavy growth of aquatic plants, algal mats and deoxygenation are common symptoms of eutrophication. 水藻滋生、水生植物大量生長、藻類雜生以及水中游離氧的減少都是富養(yǎng)化的基本特征。

And then advice on choosing the methods of deoxygenation of boiler supply water is given . 在此基礎(chǔ)上，找出它們的優(yōu)缺點，提出了鍋爐給水除氧方法選用的建議性意見。
