dissolved oxygen content 中文意思是什麼
dissolved oxygen content
解釋
溶解氧量-
The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish. the factors of dissolved oxygen concentration, fe2 + concentration, ph, p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal, and the correlation of residual manganese and oxidation - reduction potential was also discussed. as the iron content of water was high, experiment results showed that the reaction was zero order, as the iron content of water was low, the reaction was first order. the time needed for the cultivation of biological manganese removal was 60 70 days. the filter operated at the filtration rate of 8 10m / h, silica sand of effective size 0. 95 1. 25mm filled the filter to a depth of 1200mm
試驗結果表明，成熟后濾砂表面濾膜的x射線衍射圖譜與mno _ x ? 5h _ 2o （ x = 1 . 86 ）的x射線衍射圖譜一樣，濾膜成熟后的結構在進水物質不發生變化的情況下不發生變化;合適的碳磷比對生物除錳有明顯的促進作用，試驗條件下的投磷量不會對出水造成二次污染;生物除錳需要亞鐵的參與，亞鐵的存在除了能夠促進微生物分泌胞外酶並刺激其活性外，還通過鐵離子的變價傳遞電子，催化錳離子的氧化反應，從而促進對二價錳的降解。 -
The stratification is very obvious in the vertical profiles of chlorophyll and dissolved oxygen, with high content in the subsurface layer when thermocline exists
在溫躍層存在季節，黃海冷水團水域的葉綠素和溶解氧含量出現次表層最大值現象。 -
Simulate experiment, which rice wine was aerated and added with h2o2, and the content analyses showed that the oxygen dissolved in rice wine reacting with amyloses, proteins and tannin may produce the visible turbidness ( oxidizing sedimentation )
通過向酒體中通入空氣和添加過氧化氫等模擬實驗和成分分析表明，酒體中的溶解氧可與多糖、蛋白質和單寧等作用形成渾濁（即氧化沉澱） 。 -
In this paper, based on the experi ment and research data of the injected water quality in lunnan oil field in many years, the actual situation of the injected water in lunnan oil field is analyzed and discussed and the chemical indices ( content of the iron, dissolved oxygen, sulfide, carbon dioxide and oil and corrosion rote ), the bacterial index, the phys ical indices ( content and particle diameter of the suspended sub stance ) and the compatibility of injected water with formation water, etc. are evaluated one by one
文章立足於多年來輪南油田注入水水質的實驗研究數據，對輪南油田注入水現狀進行分析討論；對化學指標（鐵含量、溶解氧、硫化物含量、二氧化碳含量、含油量、腐蝕率） 、細菌指標、物理指標（懸浮物含量、懸浮物粒徑）和注入水與地層水配伍性等進行逐一評定。 -
Must be softened and treated to make sure that is free from suspended solids and non - carbonate hardness, has a low carbonate hardness, is practically free from oil and dissolved oxygen and has a low dissolved silica content
必須經過軟化和處理保證沒有懸浮固體和非碳酸鹽的硬度，有低碳酸鹽硬度 -
The results suggested that the dissolved oxygen in fresh grape wine gradually decreased after wine - filling into the barrel and its content in wine reached a steady level three months later, the dissolved oxygen content in wine varied with the liquid depth ( the deeper point in the barrel, the less of the dissolved oxygen content, however, the change trend were the same ), and for the barrels made of different wood materials, there was difference in the dissolved oxygen content in the initial three months during wine storage and such difference disappeared three months later
結果表明，新鮮酒入桶后，酒中的溶解氧逐漸減少， 3個月後達到穩定值；在橡木桶中，距液面深度不同的葡萄酒中的溶解氧含量不同，愈深含量愈低，但溶解氧的變化趨勢一致；在桶貯的初始3個月內，不同板材製作的橡木桶中酒的溶解氧含量有差異， 3個月後趨於一致。 -
