The photodissociation study of the molecule CH3ONO not only provides some useful information for an understanding of the bondbreaking processes in polyatomic molecules, but also probes a wide range of dynamic interaction responsible for the dissociation of polyatomic molecules.

CH_3ONO的光解研究不但可以提供一些有用的信息来理解多原子分子的断键过程，还可以探测多原子分子解离的动力学相互作用。

Methyl bromides, in C_(3v) symmetry, have been extensively studied at their first absorption A-band because the behavior of these molecules can be used as a prototype for depicting numerous types of photodissociations in a variety of polyatomic molecules.

例如，有很多研究报道了C_(3v)对称的溴甲烷等分子在第一吸收带的光解，这是因为其光解行为可以作为理解其它多原子分光解的原型。

In comparison with normal IgG, the hydrophobic groupsof SLE IgG molecules resided at the positive electricity regions and were exposed more to the surface of lgG molecules.

同正常人相比，SLE患者血清IgG园二色谱中213nm处负峰的椭园值比正常人的高出近一倍，IgG分子中的疏水基团处于正电区，并且趋向于分布在蛋白质分子的表面。

This displays the molecular mechanism heredity in the nucleus. DNA is composed of chain-trend ribose and root molecules of phosphoric acid, and basic pairs of molecules linked in double chains.

本展品所展示的是存在于细胞核内具有遗传特性的分子结构模型，主要由组成链走向的核糖和磷酸根分子以及双链之间互连的碱基分子组成。

With the increase of pressure, the hydrogen bond strength between water molecules increases, while self-diffusion coefficient decreases. With the increase of temperature, the hydrogen bond strength between water molecules decreases, while self-diffusion coefficient increases.

模拟结果表明，随着压强的增大，水分子间的氢键作用增强，扩散系数减小；随着温度的升高，水分子间的氢键作用减弱，有序程度下降，扩散系数增大。

A semipermeable membrane is one through which the molecules of a solvent can pass but the molecules of most solutes cannot.

半透膜允许溶剂分子通过，而大部分的溶质无法通过。

The contact mode AFM could be used to "sweep" the slipcover and expose the mark. As an example, in situ observation of the bovine serum albumin adsorption film on highly ordered pyrolytic graphite was described. When the marks, atomic steps on HOPG, were covered by BSA molecules, contact mode AFM could "sweep" the BSA molecules away.

以对高序热解石墨（Highly ordered pyrolytic graphite，HOPG）表面牛血清白蛋白（Bovine serum albumin，BSA）吸附的原位观察为例，在BSA膜覆盖HOPG表面的原子台阶后，采用接触模式AFM扫描，将BSA"扫"开，露出HOPG原子台阶作为标记，对图像上的结构进行精确定位。

There are two independent molecules of ZnL or Co(IIL and two water moleculesin one asymmetric unit of complex 1(or 2), the crystal structure of CuClL_1·2H_2O consistsof one molecule of CuClL_1 and two water solvate molecules in the asymmetric unit,while the ZnL·CH3OH (4) comprises of one molecule of ZnL and a methanolmolecule in per unit.
