今利用两种聚醚型有机硅表面活性剂DC-193和DC-190，对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究，分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

Translation - urea characteristic The urea is one kind of achromatic color, tasteless, the odourlessness acicular or the orthogonal prism build crystallizes, in the actual production is granulated for the white or the tint; The granularity may be possible to be small greatly according to enterprise's characteristic; When heats up to 132.7℃ starts to melt, the solid urea density is 1.335g/cm 3, dissolves in the water and the few organic reagents, the urea assumes the alkalescency, may live the salifying with the acid function, when the temperature surpasses 60℃, the urea in the acid, the alkalinity or the neutral solution has the hydrolisis.

问题补充：尿素是一种无色、无味、无臭的针形或正交棱柱体形结晶，实际生产中为白色或浅色颗粒状；粒度则根据企业的特点可大可小；当加热到132.7℃开始熔化，固体尿素密度为1.335g/cm 3，溶于水和少量的有机试剂，尿素呈微碱性，可与酸作用生成盐，当温度超过60℃时，尿素在酸、碱性或中性溶液中发生水解。

It was showed, the acid value and the peroxide value increased with heating time in normal condition.

The results showed that there were five kinds of anthocyanin with possible acyl groups in the purple napiergrass.

结果显示，紫色狼尾草之花青素有五种成分，可能含有乙醯基，在pH 1-8之条件下，5 ℃贮藏三个月时以pH 1及2最为稳定，若在90 ℃加热12小时后，则在pH 2下稳定性最佳。

The total flavonoids content of peanut hulls of different sources were evidently different,those peanut hulls contained more total flavonoids from Shandong province,higher maturity and raw. This suggested that attention should be paid to the choice of peanut hulls as medicine materials. 3.The optimized extraction technology conditions considering the two indices of total flavonoids andβ-sitosterol were: the peanut hulls were extracted by 95% acohole 6 times of the hulls weight refluxing for 2 hours first,and extracted by 70% acohole 4 times of the hulls weight refluxing for 2 hours at the temperature below 80℃successionally,then the concentrate was dried vacuumizedly with the additament of starch 2% of the concentrate weight after the extracts were fitrated,united and concentrated. 4.The dried extract powder possessed high hygroscopy and low fluidity,but the weight variation of capsule contents could comply with the requirement of CP if it was mixed with dextrin and granulated by sieving 40 meshes using 95% ethanol as the wetting agent,and filled into capsules after dried below 60℃.The critical relative humidity of the granules was about 63%.

不同来源的花生壳总黄酮含量有较大差异，山东产区、成熟度高的及未经炒制的花生壳总黄酮含量较高，提示作为药材时应注意选择； 3、兼顾总黄酮及β-谷甾醇的最佳提取工艺为：先以95%乙醇6倍量加热回流提取2小时，再以70%乙醇4倍量80℃以下回流提取2小时，提取液过滤、合并、浓缩，加2%淀粉60℃以下减压干燥； 4、浸膏粉吸湿性大，流动性差，但加糊精并以95%乙醇为润湿剂、过40目筛制粒，60℃以下烘干后填充胶囊，可保证装量差异符合要求；颗粒临界相对湿度约为63%。
