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。

I do not know whether the recall, China Central Television has reported that after the National Day in Tiananmen Square, remnants of chewing gum everywhere, 40 million square meters of Tiananmen Square, actually 600,000 chewing gum residues, and some less than one square meter of the ground, as many as nine of chewing gum stains, chewing gum crowded Tiananmen Square, scarred and sacred and solemn form a strong contrast.

不知大家是否记得，中央电视台曾经报道，国庆节后的天安门广场，随处可见口香糖的残迹，40万平方米的天安门广场上竟60万块口香糖残渣，有的不到一平方米的地面上，竟然有9块口香糖污迹，密密麻麻的口香糖斑痕与天安门广场的神圣和庄严形成了强烈的反差。
