With the help of the obtained normal canonical entropy, we studied the phase transition and showed that when the thermal capacity is emanative, there are no plural numbers at this point in the normal canonical entropy, which shows that the phase transition is of the second order.

利用所给出的正则熵，对黑洞的相变进行讨论，得到当黑洞的热容量出现发散时，正则熵在该处并不出现复数，由此认为此相变为二级相变。

The impact of temperature,pH and ionic strength on the volume phase transition of the hydrogels is studied.The result shows that the volume phase transition temperature of ionizable and thermosenstive copolymer hydrogels depend upon the hydrophilic/hydrophobic character of the comonomers...

结果表明，疏水基末端端基的疏水程度决定凝胶体积相变的速率，随着疏水性单体甲基丙烯酸酯烷基链的增长，凝胶的疏水性增强，凝胶的相转变pH向低pH处迁移；温度高于LCST时，分子间的氢键作用减弱，疏水基团间的相互作用加强，凝胶发生体积相变。

In this paper, we primarily study the synthesis, characterization, character of luminescence, structure phase transition and metalline phase transition under high pressure of nanocrystalline zinc sulfide.

本文以纳米硫化锌为主要对象，重点研究了合成、表征、发光特性、高压下结构相变和金属化相变，同时，辅以氮化镓和硅化铁等典型的半导体纳米材料的高压相变研究，讨论了纳米尺度对相结构稳定性的影响。

The phase transition temperature range of the self-crosslinked PNIPAM hydrogel microspheres was very narrow, and they had nearly noncontinuous phase transition behavior.

自交联PNIPAM水凝胶微球的相转变温度范围很窄，接近非连续体积相转变行为。

The results showed that PPC was a thermotropic liquid crystal and displayed the cholesteric banded texture. The reaction conditions had the distinct effects on the propoxy content and liquid crystal property of PPC, with the reaction temperature and content of propionyl chloride increased, the degree of substitution of propoxy increased at the beginning, then trended to steady. The transition temperature and range of liquid crystalline phase were changed with the DS of propoxy, as the DS of propoxy increased, the melt point decreased, and the liquid crystalline phase transition temperature range of PPC get wider.

结果表明，产物PPC具有明显的热致液晶性能，且呈现出胆甾型液晶的彩色条纹织构；反应条件对产物丙酰基含量和液晶性能有显著影响，随反应温度提高和丙酰氯用量增加，产物丙酰基的取代度先增大，后趋于稳定；其相转变温度和温域随丙酰基取代度改变而相应变化，随丙酰基的取代度增大，产物的熔点降低，液晶温度范围变宽。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。
