应用化学

As their sizes are smaller than the bulk exciton Bohr radius, theyexhibit many unique optical, electrical and chemical properties, giving rise tonumerous potential applications in physics, chemistry, biology and medicine.

由于粒子的尺寸比体相材料激子的波恩半径还小，因此表现出非常独特的光、电和化学性质，在物理，化学，生物，医药等许多方面有着巨大的应用价值。

We can find from the research that the IR and XRD spectrogram shows the exists of H_3BO_3 on the surface of cellulose;there is H~+ released form the solution and the complexation proportion of the boric acid-glucose in the solution is 1:1, the boric acid-mannitol is 1:2 and the boric acid-N-methylglucamine is 1:2;and the half experienced mathematics model experiment on analyzing PH shows that the cellulose's adsorption of the boracic acid is mainly chemical adsorption with a proportion of 1:1 while physical adsorption with the H~+ released during the reaction plays a role as assistance.

研究结果表明，通过IR和XRD谱图分析，表明纤维素上吸附了H_3BO_3；硼酸和葡萄糖、甘露醇、N-甲基葡萄糖胺在水溶中络合比分别为1：1，1：2，1：2，同时溶液中有H~+释放出来；应用半经验数学模型分析pH值-浓度吸附实验，表明纤维素对硼酸主要以化学吸附为主吸附比为1：1，以物理吸附为辅，反应过程中释放出H~+。

Methods Serum TNF-2 and NO/NOSlevels were determined in 42 patients with children broncho pneumonia both before and after treatment as well as in 35 controls.

方法分别应用放免法和化学法测定了42例小儿支气管肺炎患者血清NO/NOS和TNF-2含量，并与35名正常儿童作比较。

Methods Thirty-two normal eyes from dead people aged 20 days to 84 years and 2 AMD eyes from corpses were examined by using histochemistry stains to identify characteristics of lipid deposition in the Bruch?

应用组织化学染色的方法，对32例尸体正常眼球(20天～84岁)及2例尸体患AMD病眼进行研究，检测其Bruch膜及RPE中的脂类沉积。

Because of special chemical and biological compositions in buckwheat, it has a broad application prospect in food and medical industry.

由于它的化学和生物学成分独特，目前在食品和医药方面的应用前景十分广阔。

Firstly, quantum chemical method was employed to investigate the mechanism of cationic ring-opening polymerization of tetrahydrofuran and butylene oxide.

本文首先应用量子化学方法分别探讨了四氢呋喃和环氧丁烷的阳离子开环聚合反应机理。

Subjection of nature's forces to man, machinery, application of chemistry to industry and agriculture, steamnavigation, railways electric telegraphs, clearing of whole continents for cultivation, canalization of rivers, whole populations conjured out of the ground—— what earlier century had even a presentiment that such productive forces slumbered in the lap of social labor ?

自然力的征服，机器的采用，化学在工业和农业中的应用，轮船的行驶，铁路的通行，电报的使用，整个整个大陆的开垦，河川的通航，仿佛用法术从地下呼唤出来的大量人口，——过去那一个世纪能够料想到有这样的生产力潜伏在社会劳动里呢？

Monte Carlo simulations of phase equilibria for lattice polymer systems with chain length r=1,2,4,8 are carried out in the canonical ensemble. All chain molecules are introduced into the cell regularly upon initiation, followed by being perturbed through the repta-tion, end - rotate, crank - shaft and L - flip motions.

应用修正的Widom试验粒子方法在三维立方格子中计算了链节数分别为r=1，2，4，8的链状分子在不同温度、密度下的剩余化学位，然后运用热力学关系计算了以上系统在不同温度、密度下的化学位、压力和压缩因子，并求得系统的相平衡曲线和临界点。

In recent years, with the development of various good catalysts especially the ruthenium alkylidenes bearing N-heterocyclic carbene ligands, the RCM reaction has been applied widely in the synthesis of complex organic molecules, biological molecules and natural products etc. The Nobel Prize in Chemistry 2005 goes to Yves Chauvin, Robert H.

近二，三十年来，随着各种性能优良的催化剂的不断发展，尤其是含氮杂环卡宾配体的钌催化剂的出现，关环复分解反应在合成复杂有机分子，生物活性大分子以及天然产物等方面已得到了极为广泛的应用。2005 年的诺贝尔化学奖分别授予了 Yves Chauvin，Robert H。

Platinum and rhodium catalyst are applied largely and widely, because these two kinds of catalysts are so efficient for hydrosilylation that they were researched since a long time ago. Very recently, N-heterocyclic carbene Pt and N-heterocyclic carbene Rh complexes were used as catalysts in hydrosilylation.

最近，铂和铑的卡宾金属配合物作为催化剂应用于各种不饱和化合物的硅氢加成反应，表现出非常优良的催化性能和稳定的物理化学性质，受到了化学工作者们广泛的关注。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
