Taking the shell fabrics and adjuvants used for the winter dress as the example, based on the structure parameters test and dry-cleaning experiments with petroleum solvent and tetrachloroethylene, the sample performance before and after dry-cleaning, such as thickness, dimennsion contraction, crease recovery angle, drape coefficient bending stiffness and color difference and so on, is tested.

以冬季女上装常用面料和里料为例，在对其进行结构参数测试和石油溶剂、四氯乙烯干洗剂干洗实验的基础上，对试样干洗前后的厚度、尺寸变化率、折皱回复性能、悬垂性、刚柔性、色牢度等相关性能指标进行了测试，着重就干洗对服装面辅料性能的影响进行了对比分析和总结。

Using a phase equilibrium apparatus, the solubilities of anthracene and carbazole in dimethyformamide, N-methylpyrrolidinone, cyclohexanone, xylene, dichloroethane and tetrachloroethylene were determined and solubility curves were drawn, providing useful data for crude anthracene processing.

利用液固相平衡实验装置，测定了蒽和咔唑在二甲基甲酰胺、N-甲基吡咯烷酮、环己酮、二甲苯、二氯乙烷和四氯乙烯中的溶解度，并作出溶解度曲线，为粗蒽的分离和精制提供了有用数据。

A kind of blue encapsulated electronic ink microcapsule was prepared by in situ deposition method utilizing urea and formaldehyde solution as aqueous phase and tetrachloroethylene dissolved with oil solvent blue dye as oil phase under different pH condition and Polyvinyl Alcoholand gelatin as modifying agent,respectively.

以溶有油溶蓝的四氯乙烯为油相，以甲醛和尿素溶液为水相，分别利用明胶和聚乙烯醇作为改性剂，在不同pH条件下，利用一步原位沉积法制备出脲醛树脂微胶囊，方便快捷。

鞋油可用汽油或四氯乙烯润湿后，再用洗衣粉碱液擦洗去除。

Conclusion］The neurasthenia and lower serum albumin in workers were due to the bad ventilation in the laundries and the chronic exposure of workers to tetrachloroethylene.

结论］部分干洗房容积偏小，通风不良，作业工人长期接触四氯乙烯可能引起神经衰弱及肝功能损害。

ESCA results show that silica is coated on surface of the polymeric microspheres. SEM analysis reveals that when water was used as a solvent, uniform silica coating on the surface of organic microsphere can be obtained, and when the reactive time is 10 minutes, an uniform coating layer can be prepared. But when tetrachloroethylene was used as a reactive solvent, an inhomogeneous silica coating is found on the organic microspheres.

由化学分析电子光谱仪纵深分析可以得到，矽的前驱物是藉由披覆方式附著在有机微球表面；SEM分析发现以水为溶剂所合成出之披覆有二氧化矽的有机微球表面呈现均匀披覆效果，并且当反应时间为10min时表面均匀披覆效果最好；而以四氯乙烯为溶剂的系统所合成之微球则呈现不均匀披覆。
