The paper introduces the technologies to recover dilute ethylene in FCC dry gas from refinery,including pressure swing adsorption,conjugation absorption separation,intercooling oil absorption,advanced recovery system,and membrane separation,and makes a comparison among the technologies.

介绍了炼厂催化裂化干气稀乙烯的回收技术，包括变压吸附、配合吸收分离、中冷油吸收、先进回收系统、膜分离技术，并对这几种技术进行了比较。

When different materials mixed,the mixture will have a mixed melting point of mixture ,and the mixed melting point of mixture is different from the intersoluble solutions.we separate the intersoluble solutions by different melting piont of intersoluble solutions when separate temperature is flexible temperatureThese intersoluble solutions different in melting point, the method would make the high melting point material became solid while the low melting point material still be liquid by adopting cryogenic treatment with stirring so as to meet the requirement of purifying these two solutions.

这种分离方法的特点是利用两种互溶性物质具有不同的熔点，通过低温处理，并同时加以搅拌，震荡，使高熔点物质和低熔点物质形成固液混合体，再对固液混合体进行离心分离得到高熔点的固体和低熔点的液体，从而达到浓缩、提纯两种物质目的。

All compounds have been isolated from Inula cappa for the first time.

所有化合物均为首次从该植物中分离得到，其中1~8，11~12为首次从该属植物分离得到。

Although most workers have found that samples containing ionizable components usually are best separated with mobile phases that have a pH less than or equal to 3 , some separations may be impossible at a low pH because components of the sample are unstable at a low pH; protonated basic compounds are eluted too soon; and required band spacings are unobtainable.

尽管许多工作者发现含有离子化组分的样品在流动相pH值低于或等于3的时候有最佳的分离，但许多样品不可能在低pH下分离，因为样品中组分在低PH下不稳定、质子化的生物碱洗脱太快、和不能达到要求的峰间距。

The influence of concentration and pH of the mobile phase on the separation and detection was investigated. The elution and separation were carried out with an isocratic mobile phase containing 10 mmol/L NaOH. A quadruple-potential waveform used for the detection was optimized. The detection limit of neomycin was down to 27 ng/mL.

考察流动相浓度和pH对色谱分离和检测的影响，确定色谱分离的最佳流动相条件为10 mmol/L NaOH溶液，并优化新霉素的测定电位和电极的活化电位，获得脉冲安培的最佳四电位检测模式。

According to the chromatograms, we choose the several peaks which are more abundance as the characteristic peaks. Additionally, to compare the isocratic elution and gradient elution two systems, we find that it is obviously better to use the gradient elution.

另比较以等位冲提及梯度冲提方式进行高效能液相层析仪分离的结果，发现使用梯度冲提的分离效果明显较好。
