查询词典 gum-elastic

Tooth-correct, because of the reason of the Jiao tooth machine, majority all will the engine gum atrophies of linger effect, correct process in or the Jiao tooth uses tooth gold behind, the tooth gold can make the atrophic gum directly absorbed enough nourishment when contains and make atrophic gum reborn thus and shut to match appear because of tooth-correct of difficult see a gum of blind side, avoid bring because of the tooth-correct of the gum atrophy linger effect.

牙齿矫正，由于矫牙器的原因，多数都会引擎牙龈萎缩的后遗症，矫正过程中或矫牙后使用牙齿黄金，牙齿黄金在口含的时候可以让萎缩的牙龈直接吸收到足够营养，从而令萎缩的牙龈再生，闭合因牙齿矫正而出现的难看牙龈缝隙，避免因牙齿矫正带来的牙龈萎缩后遗症。

The latest research discovers, hangs the decrease that the body some growth hormones secretes or stops because of the adult brain, will cause mouth cavity and gum's absorption toward vitamin C's appearing a serious obstacle and bring mouth cavity and the gum serious malnutrition thus, the serious result brought by this kind of malnutrition, the reaction atrophies physiology degeneration in the gum phenomenon consumedly advance of reality, this is also though people for brush teeth to wait after mouth cavity sweep value, the gum atrophies to still and gradually present the root reason that the low age turns.

据最新的研究发现，由于成年人脑垂体某些生长激素分泌的减少或停止，会导致口腔及牙龈对于维生素C的吸收出现严重障碍，从而带来口腔和牙龈严重的营养不良，这种营养不良所带来的严重后果，反应在牙龈萎缩生理退化现象大大提前的现实，这也是尽管人们对于刷牙等口腔清洁重视之后，牙龈萎缩仍旧日趋呈现低龄化的根本原因。

The tartar is a gums various tooth week the harmful germ stirs up a ratio can not little"carry a body", because the gum atrophies, but be disgusted with making oxygen germ can stir up, spread under the gums, hit gum and tooth over a long period of time the week organizes of health;In the meantime such as front say of because of the malnutrition of gum, this eliminates that long under, then cause the adult mouth cavity resist the disease violate of ability, along with age growth but significantly decadent result, thus cause various gum burning, tooth week burning, tooth Sui burning symptom.

牙石是龈下各种牙周有害病菌滋生比不可少的"载体"，由于牙龈萎缩，而令厌氧菌在龈下得以滋生、扩散，长期侵袭着牙龈和牙周组织的健康；同时如前面所说的由于牙龈的营养不良，此消彼长之下，进而导致成年人口腔抵抗疾病侵害的能力，随着年龄增长而大幅衰退的结果，从而引发各种牙龈炎、牙周炎、牙髓炎症状。

From the UV spectra, it can be found that the aromaticity of acenaphthenyl groups in C_2 gum is the largest. But there are 30 carbon atoms in the conjugated structure of condensed aromatics in C_1 gum and C_3 gum, while 28 carbon atoms in acenaphthenyl groups in C_2 gum.

但是，在C_1胶、C_2胶和C_3胶三者中，C_1胶侧链上的四苯基苯基和C_3胶侧链上的菲式多苯基苯基都含有30个碳原子，而C_2胶侧链上的苊式多苯基苯基含有28个碳原子，比前面二者小2个碳原子，理应其芳香性在三者之中最小，但事实却恰恰相反。

So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。

So, by the Diels-Alder reaction of tetraphenylcyclopentadienone, acenaphthenecyclone and benzophenanthrenecyclone with the vinyl groups in C gum, three kinds of polymethylvinylsilicone oil with condensed aromatics are synthesized respectively: polymethylvinylsilicone oil with tetraphenylphenyl groups (called C_1 gum for short), polymethylvinylsilicone oil with acenaphthenyl groups (C_2 gum) and polymethylvinylsilicone oil with benzophenanthrene groups (C3 gum).

根据此原则，利用四苯基环戊二烯酮、苊式环戊二烯酮和菲式环戊二烯酮与C胶上的乙烯基进行Diels—Alder反应，分别合成了三种含稠环基团的乙烯基硅油：四苯基苯基乙烯基硅油(C_1胶)，苊式多苯基苯基乙烯基硅油(C_2胶)和菲式多苯基苯基乙烯基硅油(C_3胶)，并根据~1HNMR谱图上不同氢原子的积分面积计算了三种胶中稠环基团和乙烯基的含量。

It turns out that there is no synergistic interaction between xanthan gum and hydroxypropyl starch , CMCNa. Xanthan gum and guar gum ,locust bean gum ,konjak flour have great synergistic interaction. If two or three of them mix with proper proportion, the stability of salt tolerance will greatly improve and the co...

研究结果表明：黄原胶与羟丙基淀粉、CMC－Na复配无协同增效作用，黄原胶与刺槐豆胶、魔芋精粉、瓜尔豆胶有良好的协同增效作用，两者或三者按适当比例配合后，耐盐稳定性显著提高，用量比任一单一胶少，而且使用成本大幅度降低，因此复配食品胶在高盐食品中使用具有明显的优越性和广阔的应用前景。

English Synonyms: carob gum; locust bean gum, Cassia bean gum, carob gum long.

中文别名：角豆胶；洋槐豆胶，槐豆胶，长角豆胶。
