目的：评价肝移植术后患者血清总胆汁酸水平、胆酸，鹅脱氧胆酸比值在肝移植术后发生排斥反应及肝功能延迟恢复时的变化规律。

Iminodiacetic acid and aspartic acid reacting with t-butyloxycarbonyl anhydride in the basic solvent system of 1,4-dioxane-water gave better yields than those from conventional t-BuOH/H 2O system method,while glutamic acid in both solvent systems of 1,4-dioxane-water and tetrahydrofuran-water also gave better yield.

其中Boc酐法反应条件温和，操作简便，试剂易得且经济，是实验室制备Boc保护的氨基酸的常用方法。常规Boc酐法多采用叔丁醇水和四氢呋喃水的溶剂体系。我们用常规Boc酐法制备Boc 亚氨基二乙酸时，多次重复，收率总是低于 5 0 %，对天冬氨酸和谷氨酸进行Boc化时也有类似情况。

We synthesized polynitrobenzenes by oxidation of polynitroanilines by peroxysulfuric acid (hydrogen peroxide dissolved in sulfuric acid, it is also known as Caro's acid) several years ago.

我们曾在若干年前用过硫酸(过氧化氢溶于硫酸中，亦称卡洛氏酸)氧化多硝基苯胺而合成了多硝基苯类(硝基数3至6)。

In addition, in-situ infrared spectroscopy provides the information about the nature of the surface acid and base sites. For example, Lewis acid and base sites on metal oxides are coordinatively unsaturated metal cations and oxygen anions, respectively, while Brinsted acid and base sites are the hydroxyl groups on the surface.

结合原位红外光谱，还能够详细地了解表面酸碱中心的性质：金属氧化物表面的Lewis酸中心和碱中心分别是表面配位不饱和的金属离子和氧负离子， Brinsted酸中心和碱中心则是金属氧化物表面的羟基。

In two series experiments by-pass nitrogen, amino acid passage to the abomasum, rureen metabolic parameters and nitrogen utilization were studied respectively.

利用四头装有瘤胃和皱胃瘘管的阉公羊以及四头未装瘘管的阉公羊进行两系列实验，测定通过瘤胃蛋白、皱胃氨基酸通过量以及瘤胃消化代谢和氮的利用。

The purity identification was made by SDS-PAGE,absorption spectrum and amino acid analysis.

SDS-PAGE电泳结果显示提取纯化的Ⅱ型胶原蛋白与S igm a公司的产品一致。
