hydroxyl oxygen 中文意思是什麼
-
Deoxy sugar a sugar in which oxygen has been lost by replacement of a hydroxyl group ( oh ) with hydrogen ( h ). the most important example is deoxyribose
脫氧糖：羥基被氫原子置換導致失去氧的一類單糖。最重要的脫氧糖就是脫氧核糖。 -
For example, poly ( xylylviologendibromide ) and 4, 5 - bis ( 4 - methoxyphenyl ) - 2 - ( 4 - nitro - pheny ) imidazolium acetate di - hydrate ( c23h20n3o4 + c2h3o2 - 2h2o ), the hydration or dehydration of the crystal structure is related to the color charge of the crystal. the thermochromic schiff bases are the other family of compounds that show a self - isomerization induced by an intramolecular proton transfer from the hydroxyl oxygen to the imine nitrogen through the o - h. . n hydrogen bond, and they were observed thermochromism
利用液相法合成了兩種具有熱色性新的有機水合物， x射線單晶衍射確定了這兩種水合物的結構，利用uv 、 ir 、原位升溫紅外、原位升溫紫外、 tg - dsc探討了它們的變色機理。 -
The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment, and at the same time, the gel content had extreme value with the change of the dose rate. the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment, narnely rough degree increasing. their number and deepness increased with increase of dose. and this phenomenon is the most obvious when the dose rate was 8. 5kgy / s and the dose was 400kgy. at the same time some containing oxygen groups, including hydroxyl group, carbonyl group and carboxyl group, were introduced into the fiber surface which was exposed to the air
研究表明， uhmwpe纖維經電子束輻照處理后，纖維的拉伸斷裂強度隨劑量率的增加呈下降趨勢，凝膠含量隨著劑量率的變化存在極值。纖維表面出現了不規則的微裂紋和凹痕，隨著劑量的增大，電子束對纖維表面的刻蝕程度增加，在本研究中以劑量為400kgy劑量率為8 . 5kgy s時刻蝕效應最為明顯。同時，在空氣中進行輻照時，纖維表面被引入了一些含氧基團，包括羥基、羰基和羧基。
