Cooking alters food in three important ways. It breaks starch molecules into more digestible fragments. It "denatures" protein molecules, so that their amino-acid chains unfold and digestive enzymes can attack them more easily.

烹饪对食物产生了三方面的影响：它将淀粉分子转变为更易消化的微粒；它改变了蛋白质分子，瓦解氨基酸链从而使消化酶更容易附着其上；它通过加热使食物变得更软。

But anisodamine can cause interdingitation in DPPG/DPPC mixture, that is, the DPPC phospholipid molecules can produce an interdigitated structure with the DPPG phospholipid molecules interdigitating.

当DPPG／DPPC摩尔比为2：1或1：1时，其脂酰链末端插到对面分子层第八个碳原子的位置。当DPPG／DPPC摩尔比为1：2时，就不能发生交插而呈完全的非交插状态。

First by confining and concentrating molecules, then by selecting and arranging those molecules, minerals may have jump-started the first self-replicating molecular systems.

矿物首先圈住分子加以浓缩，接下来是筛选并联结这些分子，因此也许便催化产生第一个有复制能力的分子系统。

The yield of glycolysis is 2 molecular of ATP plus 2 molecules of the reduced coenzyme NADH2 for each molecules of glucose respired.

每分子的葡萄糖可以转化成2分子的 ATP 和2分子的还原型辅酶 NAPH2。

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。

Most of water-soluble cyanine dyes have -SO3H and –COOH in their molecules, which will influence the biomolecules' functional characters. A new kind of water-soluble cyanine dyes with several cations in molecules were designed and synthesized, preparation conditions of intermediate and dyes were researched and optimized, the yield of dye is 25%. The novel kind of cyanine dye are water-soluble , spectrum characters was researched , all the dyes were charactered by 1H NMR and TOF-MS, spectrum in different solvent of novel dyes were focused on, one of the kind dyes show higher fluorescence quantum yield than the result reported. Because of several cations in the structure, it is promising when used in DNA assay and other bio-assay field.

大多数水溶性的菁类荧光染料分子结构中都带有-SO3H和-COOH等基团，过多的阴离子的引入容易造成对生物分子的功能属性的影响，本论文设计并合成了分子结构中带有多个正电荷的水溶性的一类新型菁染料，考察并且研究了中间体和染料的合成条件，最终的目标产物产率达到25％，染料通过了质谱和核磁的表征，新型的染料具有良好的水溶性，研究了新染料在多种溶剂的的光谱性质，其中一种染料的在水中的荧光量子产率比文献报道得到了提高，由于富集了正电荷，这类菁染料在DNA标记等生物中有一定应用前景。

For physisorption of organic molecules on chemically inert graphite, the interaction between the adsorbates and the substrate was very weak, which provided an opportunity to image the molecules with a minimum of substrate perturbation.

有机分子物理吸附在惰性基底石墨上时，分子和基底之间的相互作用很弱，吸附分子的STM图像反差主要由分子本身的性质决定。

Heating at different temperatures, the quantity of the desorbed water molecules is different, and without complexed water molecules, the cation H〓 can react with o-Ps.

在不同温度烘烤下，脱去其络合水分子的数量是不同的，而脱去络合水的阳离子H〓会与o-Ps发生化学反应。
