Hydrates are crystalline, non-stoichiometric, clathrate compounds, and are formed from certain guest molecules when contracted with water at favorable temperature and pressure conditions.

水合物是一种非化学计量的笼形结晶化合物，由客体分子物质和水在一定温度和压力条件下形成的结晶状物体。

Gas hydrates are defined as the crystalline solid, or clathrate hydrates, which are formed by some types of low mass molecular gases, such as methane, carbon dioxide, and hydronitrogen et al, with water under relatively high pressure and low temperature conditions.

天然气水合物是一些具有相对较低分子质量的气体如甲烷，二氧化碳、氮气等在一定温度和压力条件下与水形成的内含笼形孔隙的冰状晶体。

The gas appears to be clumpy, forming thousands of comet-shaped knots each spanning about twice the size of our solar system.

这些氢分子云气的分布不均，聚成了数以千计的彗星状纠结，每一个的大小大约是我们太阳系的二倍大。

Then a new way was defined to prove that the unique set of sequences equivalent to context-free languages can be obtained by mixed self-assembly of mole-cules with 1-,2-,3- sticky ends,which is a supplement for Winfree's theory that the self-assem-bly of dendrimer nanostructures is equivalent to context-free language.

另一方面，文中定义了一种新的通过上下文无关语言通过自装配产生线性语言的方法，即证明了等价于上下文无关语言的特定序列集能通过1-，2-，3-粘头分子的混合自装配产生线性语言，同时，这是对Winfree关于树状纳米结构自装配等价于上下文无关语言理论的一个较好的补充。

In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

在化合物2中，我们引进了硫原子在冠状醚中，则应对电子密度较低之金属有较好的结合能力，实验结果显示了此分子对铜离子有相当好的选择性和结合能力，萤光增加可达60倍；同时由红外光吸收光谱和核磁共振光谱滴定实验可确知，香豆素衍生物上的两个羰基对金属离子的选择性及结合上扮演相当重要的角色。

层状类钙钛矿结构有机-无机杂合物是由有机、无机组元在分子尺度上组装而成的一类新材料，其结构和能带具有可设计可控性，因此应用前景广阔。

The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

从自扩散系数、横向弛豫和质子距离等NMR测定参数推测，在浓度为0.26 mmol/L（318 K）的N，N′-双-α，ω-丙烷溴化铵(16-3-16)溶液中形成了近似球形的胶束，胶束表面的带正电荷的铵基极性头呈锯齿状排列以减弱分子间静电排斥力的影响。

The dimerization of methylene blue in organized molecular assemblies including micelle, O/W microemulsion and lamellar liquid crystal was investigated.
