Chapter four. Two glucosamide-based trisiloxane Gemini surfactants which were connected with the short carbon chain dialcohol diglycidyl ether spacer were synthesized and their properties were determined. These compounds were structurally characterized by their 1H and 13C NMR spectra and elemental analysis.

界面性能通过K12表面张力仪测定，在临界聚集浓度CAC为1一3、10一5时可以显著地降低水的表面张力值至约21 mN/m，比连接基为低碳链二缩水甘油醚的略低，其CAC值随着乙氧基数的增加而增加，其CAC值比相应的单体低1~2个数量级，而且有两个CAC值。

The dissertation contains three chapters: Chapter One Phonetic Study On Tones and Tone Sandhis At first, the author introduces the traditional dialectological description and analysis on the tones and tone sandhis of the Shanghai dialect.

先介绍传统方言学对上海方言声调的描写与分析，再用现代语音学的方法，对上海方言的单音节声调和两类双音节连读变调的声学特性（基频F0和时长）作出描写和分析。

By polarized FT-IR spectra and Grazing Incident-IR spectra the molecules in the LB films were found to show apparent dichromism.

掠角反射红外光谱与透射红外光谱比较及偏振红外光谱实验发现LB膜中分子取向表现出了明显的二向色性，显示在MⅢ和PⅠ的LB膜中介晶基取向趋于垂直于膜面，表面压力升高时更是如此。

Results In dioestrous mice, many iNOS+ cells were found in the stroma of endometrium. There was no obvious differences between the immunized mice and the control mice. In the uterus on 3 day of pregnancy, however, there was obvious difference about the iNOS quantity in uterus between the immunized and the control mice. There was strong positive reaction on the epithelia of endometrium and the endometrial gland in the lamina propria in control mice, while the staining of iNOS in the uterus of SA-30 immunized mice was very weak, only a few of iNOS+ cells were observed in the myometrium.

结果 SA-30免疫后对间情期小鼠子宫内的iNOS没有明显影响，无论是免疫组还是对照组，在子宫内膜基质中均有大量阳性细胞分布，两者无明显差异；在妊娠第3d时，对照组的小鼠子宫中有较多iNOS表达，阳性标记主要集中在内膜上皮及固有膜中的子宫腺上，经SA-30免疫的小鼠子宫中，iNOS表达则显著减少，整个内膜标记极弱，只在子宫肌层内有少量iNOS阳性细胞分布。

结果 SA-30免疫后对间情期小鼠子宫内的iNOS没有明显瘙痒影响，无论是免疫组还是对照组，在子宫内膜基质中均有大量阳性偏瘫细胞分布，两者无明显瘙痒差异；在妊娠第3d时，对照组的小鼠子宫中有较多iNOS表达，阳性标记主要集中在内膜上皮及固有膜中的子宫腺上，经SA-30免疫的小鼠子宫中，iNOS表达则显著减少，整个内膜标记极弱，只在子宫肌层内有少量iNOS阳性偏瘫细胞分布。

As can be seen in Fig. 5, dipropyl ether will be recovered in the distillate using 1-pentanol, N,N-dimethylformamide and 2-ethoxyethanol as entrainers and butyl propionate is the only entrainer studied that inverts the volatility of the azeotropic mixture.

从图 5可以看出，使用1-戊醇、N，N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收，丙酸丁酯是唯一与共沸混合物挥发性相反的共溶剂。

Dipropyl ether will be recovered in the distillate using 1-pentanol.

使用1-戊醇。N.N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收。

Chapter 1: The reactions of methylenecyclopropanes with phenylsulfenyl chloride or phenylselenyl chloride give cyclobutene derivatives along with ring-opened products in good total yields at 0 °C in various solvents. The reactions of methylenecyclopropanes with diphenyl diselenide give the di-phenylselenyl substituted ring-opening products which can be transformed to 2,5-dihydrofuran derivatives under the oxidation with hydrogen peroxide at room temperature.

在第一章中，我们发现亚甲基环丙烷类化合物在0℃时即可很快与苯硫氯或苯硒氯发生反应生成取代环丁烯类化合物和正常的开环产物；而与二苯基二硒的反应则需加热到150℃以上才能进行反应，生成的二苯硒基开环产物在双氧水氧化下可以转化为取代二氢呋喃类化合物。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
