Analyses of spectral structure and surface tension of solutions suggest that the hydrophobic hardrocarbon chain of surfactants was partly included in the apolar cavity of β-CD and the part with the polar head group of hydrocarbon chain located outside the cavity coiled over the top of β-CD, providing an effective protection for RTP.

组成测定表明溶液中形成了稳定的1：1：1/1-BrN：β-CD：AS三元包合物。光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内，未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护。

In order to know more about the microcosmic structure of the important biochemical model molecule formamide in aqueous solution, the Optimized Potentials for Liquid Simulations-All Atom model were used in the molecular dynamics simulation for the aqueous solution of FM in the whole concentration range. The radial distribution functions of the solutions were obtained. The interaction between water molecule and FM molecule was analyzed and calculated.

为了解重要的生化模型甲酰胺在水溶液中的微观结构，采用全原子力场在全浓度范围内对甲酰胺溶液进行了分子动力学模拟，得到了溶液的径向分布函数，分析计算了溶质和溶剂分子间的相互作用，对甲酰胺和水分子的氢键缔合情况进行了分析。

Silicon phthalocyanine dihydroxide was prepared from silicon phthalocyanine dichloride through two methods. The first was alkali treating that meaned silicon phthalocyanine dihydroxide was treated in the ethanol solution containing sodium methylate .The second was acid treating meaned precipitating its solution in concentrated sulfuric acid into ice water. The product yield of the second method was 77.0％, which was higher than the method of alkali treating.

此外将合成的二氯酞菁硅采用两种方法转化为二羟基酞菁硅，第一种方法是碱处理法即将二氯酞菁硅在甲醇钠的乙醇溶液中回流得到，最高收率为53％第二种方法是酸处理法即采用二氯酞菁硅的硫酸溶液在冰水析出的方法转化为二羟基酞菁硅，其中酸溶析出法收率为77.0％。

We found that the time coefficients of POTT 、POTTOT and POTPyOT in solution are the same (~0.6ns) due to Intersystem crossing.However, the decay ISC time coefficient is 2.0ns for POTPy. We propose that rotation of the single bond between adjacent thiophenes enhances the rate of ISC. The results of these compounds in PMMA films and theoretical calculations confirm this mechanism.

在动力学量测方面，POTT、POTTOT及POTPyOT在溶液的结果是相似的，系统间转换过程的衰减时间常数都是~ 0.6 ns，然而在POTPy溶液中~ 2.0 ns，我们推测噻吩与噻吩之间单键的旋转运动加速了系统间转换的过程，而这个假设将由PMMA薄膜及理论计算的结果来加以证实。

Sperm of Anguilla japonica remained immotile when the semen was diluted in NaCl,KCl or glucose solution which isotonic or hypotonic to the seminal plasma.The sperm became motile in media containing NaCl,KCl or glucose if the osmolality was higher than that of the seminal plasma.

日本鳗鲡的精子在低于或等于精浆渗透压（≤766.1 kPa）的溶液中不运动，在一定渗透压范围内（1 021.4～3 830.4 kPa），超过精浆渗透压的溶液可激活精子。

PAA/PVA IPN hydrogels were prepared by a sequential method by which acrylic acid firstly. polymerizes and cross-links in PVA/water solution with UV irradiation,then PVA physical cross-linked hydrogels are formed in cross-linked PAA networksby freezing-thawing. The orthogonal test design method was used to optimize theexperimental conditions based on the mechanical and swelling properties of thehydrogels. The effect of the PAA and crosslinking agent contents on the microscopicmorphology of the PAA/PVA IPN xerogel was investigated by transmission electronmicroscopy, and on the mechanical properties of the hydogels was studied bymeasurements of mechanical properties.
