The solubilities in some solvents were investigated and solubilization abilities of OCC for water-insoluble drugs were evaluated. The results show that the degree of substitution of carboxymethyl groups and octyl groups are determined to be 115.9% and 58.0%, respectively. OCC are insoluble in organic solvents while show a much better solubility in water and formed opalescence solutions, which increased the solubility of paclitaxel up to 500 folds in water. The drug loading and drug encapsulation efficiency of OCC are 34.6% and 89.9%, respectively.

所制备的OCC羧甲基取代度为115.9%，取代主要发生在6位羟基上；辛基取代度58.0%，取代主要发生在2位氨基上；与壳聚糖相比，OCC分子间／内氢键作用减弱；OCC在常用的有机溶剂中不溶，但在水中溶解度增加，能够形成具有淡蓝色乳光的纳米胶体溶液，对难溶性抗肿瘤药物紫杉醇具有优越的增溶能力，使紫杉醇在水中的溶解度提高近500倍，载药量34.6%，包封率为89.9%。

In processing ceramic glaze, it boasts wide range of application,sound opalescence and fluidity as well as good wear resistance and whiteness and low radioactivity, thus cannot be affected by firing conditions while can prominently improve the combining property between clay and glaze and increase glaze surface's hardness, which also explain its popularity in ceramic production.

硅酸锆之所以在陶瓷生产中得以广泛应用，还应为其化学稳定性好，粒度细，分布合理，白度高，放射性低，因而不受陶瓷烧成气氛的影响，且能显著改善陶瓷的坯釉结合性能，提高陶瓷釉面硬度。

The critical point means such a state that all the differences between gas and liquid disappear completely,being a most important parameter of dividing the types of fluid and being widely verified in both theory and practice.Currently,four methods of determining critical point are summarized as follows:①laboratory measurement through examining critical opalescence or recording the bubble point and dew point curves;②empiric relation;③calculation of the bubble point and dew point curves by PVT software;and ④ direct calculation according to thermodynamic theories.

随后对临界点进行确定，临界点是气液一切性质差异均消失的状态，是区分流体类型最重要的参数，并得到了理论和工程应用的广泛验证，目前确定临界点大致有四种方法：①实验测定，通过观察临界乳光现象或记录流体的泡点和露点线；②经验关系式；③通过PVT软件计算流体的泡点和露点线；④利用热力学理论直接计算。

The saturated liquid densities of HFC227ea and the vapor-liquid coexistence curve were measured, the critical temperature and critical density were determined by the critical opalescence phenomenon, and then the critical pressure was determined by vapor pressure equation.

测量了HFC-227ea饱和液体密度和临界区的气液共存线，确定了HFC-227ea的临界温度、临界压力、临界密度；推算了HFC-227ea的饱和气体密度，并验证了其可信度；关联了饱和气液密度，提出了高精度的HFC-227ea饱和气液密度关联式；关联了临界区气液共存线，可精确再现HFC-227ea临界区性质，并根据临界幂定律导出了HFC-227ea的临界指数和临界幅值。

All lenses were classified using the lens opacities classification system Ⅲ based on four categories: nuclear color, nuclear opalescence, cortical cataract and posterior subcapsular cataract. ALs were measured 20 times with an IOL Master, 5 times with an IOL Master version 4.0, and 5 and 15 times with an IOL Master version 5.0 and the results were recorded.

IOL Master 5.0版相对于传统IOL Master采用了组合信号分析技术，将多个低信噪比（signal-to-noise ratio，SNR）的单次眼轴测量结果进行叠加组合，使噪音相互抵消，而反映黄斑中央凹位置的信号被放大，从而提高了SNR。

Heat-treating within the temperatures range 700 to 800℃, the transition temperature of heat-treated C-glass became higher with increasing heat-treatment temperatures and gradually approached the transition temperature of the B-glass without TiO〓; the appearance of the C-glass gradually changed from brown-violet colour to intense blue-violet colour and even to opalescence; and the phase separation morphology of TiO〓-rich phase gradually changed from an interconnected phase to a siliceous droplet phase embedded in SiO〓-rach matrix phase with increasing the heat-treatment temperatures.
