潜溶剂

In gravure printing ink often choose those that will in not more than normothermic or alkanones, the chemonucleolysis of solid and semisolid material, and forms a transparent or light-coloured solation liquid as solvents, cosolvents or sub－.

在凹印油墨中常选用那些能在常温或不高于沸点的情况下，溶解分用固体和半固体物质、并形成透明或浅色溶液的液态物质作为溶剂、助溶剂或潜溶剂。

Aim To investigate the combined effect of cosolvent and cyclodextrin on solubilization of insoluble drugs.

目的 研究潜溶剂和环糊精对难溶性药物的联合增溶作用。

The validated mathematical model can be used to explain and predict the combined solubilization of the two insoluble drugs in different cosolvent systems.

该数学模型可以用于解释和预测潜溶剂和环糊精对难溶性药物的联合增溶作用。

The results showed being a cosolvent of PVF,γ-butyrolactone could decrease obviously the melting temperature of PVF, and prevent effectively the thermal degradation of PVF.

实验结果表明，γ-丁内酯作为PVF的潜溶剂可以显著地降低PVF的熔融温度，有效地阻止加工过程中PVF的热降解。

It is both a chemonucleolysis bidentata resin eucaryote such as solvents, dilution is also thinner and sub－ ureplasm of cosolvents.

它既是溶解树脂等高分子物质的真溶剂，也是起稀释作用的稀释剂和起潜溶作用的助溶剂。

Through XRD analysis, as the temperature of cosolvent and mass transport goes up, the wave peak intensify of tin dioxide becomes more obvious. By means of SEM, tin dioxide particulates are found evenly distributed on the matrix and the quantity of particulates become higher with the increasing cosolvent concentration. The size of particulates is about 30-50nm.

经XRD分析，复合材料中二氧化锡之波峰强度随潜溶剂浓度与质传温度之增加越趋明显；SEM观察则发现，二氧化锡颗粒析出物系均匀分布於基材内，且析出物的含量随潜溶剂浓度增加而增加，析出物的尺寸约30-50nm。

Through visible wavelength and the UV spectrum analysis, the transmittance is found declined as the mass transport and the cosolvent concentration increases and the cut-off wavelength tends to shift to long wavelength.The FTIR spectrum analysis shows that tin dioxide particulates and PMMA has no obvious surface bonding. Therefore, no new absorption peak is found and so do the change shown on the wave shape.

经由可见光及紫外光穿透光谱分析，发现其穿透率随质传温度及氯化锡/甲醇潜溶剂浓度增加而下降，且截止波长有往长波长移动的现象；经红外光光谱分析，析出的二氧化锡颗粒与PMMA并没有明显的界面键结，故并无新的吸收峰出现，波形改变不明显。

The study investigats the mass transport and hydrolysis behavior for poly in various concentrations of methanol/ tin chloride (SnCl2·2H2O) cosolvent between 40℃ to 60℃. Furthermore, by using the successfully manufactured poly/ tin dioxide nano composites, the mechanical, optical and thermal properties are investigated.

中文摘要本研究系探讨在不同质传温度(40℃~60℃)下，聚甲基丙烯酸甲酯於不同浓度之氯化锡/甲醇潜溶剂(0g/100g、3g/100g、5g/100g、7g/100g及9g/100g)中的质传及水解行为，并利用成功制得之聚甲基丙烯酸甲酯/二氧化锡奈米复合材料，进一步探讨奈米复合材料之光学性质、机械性质及热性质。
