Reverse-phase chromatography was employed for chiral separation of tropine acid enantiomers on the cellulose tribenzoate chiral stationary phases coated on a small-particle spherical silica support in an eluant system consisting of a mixture of alcohol and water.

摘 要：以乙醇-水流动相，用纤维素-三作为手性固定相对外消旋体托品酸进行了高效液相色谱手性分离考察了不同比例的乙醇-水流动相、不同流速以及用不同醇类酯化对托品酸酯在手性色谱柱上的色谱行为。

This conclusion is derived can get a reverse inference - the same type of animals of different species evolved in different environments formed.

这个结论逆向推导又能获得一个推论——同一类动物的不同品种，是在不同环境下进化形成的。

Since I joined the institute, my efforts have been mainly contributed to set up the RNA platform with the large-scale zonal gradient ultracentrifuge isolation system and reverse-phase HPLC system. At the meantime, I set up the in vitro translation system as the working method to study the ribosome and the translational factor LepA(EF4) functionally and structurally.

同时，主持所RNA平台建设，在此基础上建立了大规模密度梯度分离技术平台、反向HPLC的RNA分离技术平台，在实验方法上建立起了蛋白质体外表达平台，在体外研究翻译过程的每个步骤、每种因子，从微观上认识蛋白质翻译过程的机制。

Then,two geologic models were designed,including layered model and interface undulated model,which were used to carry out post-stack reverse time migration by spectral element method on forward modeling results in anisotropic and isotropic medium.

设计了层状和界面起伏两个地质模型，分别在各向异性介质和各向同性介质条件下对正演模拟结果进行了谱元法叠后逆时偏移。

Intimal areas were measured using morphometric analysis of perfusion-fixed vein graft specimens, and intimal thickness was calculated using circumferential measurements. The SMC proliferation was studied by the immunohistochemical detection of proliferating cell nuclear antigen. Expression of MMP-2、MMP-9 mRNA in vein grafts and unoperated control Vein grafts was detected by reverse transcription polymerase chain reaction. Substrate gel zymography was used to determine the proteolytic activity.
