修饰

The excitation and fluorescence spectra were taken with leaves and the relevant molecule samples prepared in thelaboratory,including Chla,pheophytin Aand pheophorbide A.

为此我们从海带里提取Chla，然后采用分子修饰的方法对Chla分子进行一步步修饰分别生成脱镁叶绿素A和脱镁叶绿素甲酯一酸A。

Using two methods combined(urea and phosphation modification, urea and pH modification) to modify SPI, when urea concentration was 3mol/L, at pH 10, it had the largest adhesive strength, and good water resistance ability.

采用尿素变性和磷酸化、尿素和pH变性两种方法复合修饰SPI，与单一的化学修饰方法相比，尿素浓度为3mol/L、pH为10时，所得到的胶粘强度最大，耐水性也很好。

In order to improve the electrocatalytic activity of the anode in the Direct Methanol Feul Cell, three kinds of transition metal substituted phosphomolybdic acid modified platinum electrodes were prepared, and the electrochemical behavior in the sulphuric acid solution of transition metal substituted phosphomolybdic acid modified platinum electrodes and their electrocatalytic effects of methanol oxidation were studyed. The anti-poison effect to carbon monoxide of the prepared electrodes were studied by the carbon monoxide adsorbing.

为了提高直接甲醇燃料电池阳极催化活性，本文研究了三种过渡金属取代磷钼酸修饰铂电极在硫酸溶液中的电化学行为及对甲醇的电催化氧化作用，并利用一氧化碳吸附实验评价了三种过渡金属取代磷钼酸修饰铂电极的抗一氧化碳毒化性能。

While in photoreduction of Cr , the titania-modified MCM-41 photocatalysts were more photoactive than the titania-silica composite (25％ TiO〓).

在光催化降解苯酚中氧化钛修饰MCM-41的光催化活性虽然不及结晶的锐钛矿相纳米氧化钛，但是仍具有较高的催化活性；在光催化还原Cr到Cr反应中氧化钛修饰MCM-41的光催化还原性明显高于部分结晶的TiO〓-SiO〓（25wt％TiO〓）复合氧化物。

The aim of this thesis is to create a new series of covalently bonded inorganic-organic hybrid materials based on polymolybdate clusters by exploiting appropriate metal cations or organic ligands as linkers according to the concept of crystal engineering.

本论文得到的化合物均不溶于水和常见的有机溶剂，因而大部分被用来作为化学体修饰电极的修饰材料，详细地研究了它们的电化学性质。

A stable, water-insoluable film was prepared by oxidative electropolymerization of pyrogallol in pH7.0 phosphate buffer solution, anti modified on a glassy carbon electrode surface by electrochemical method. The modified electrode was exploited for the selective preconcentration of Cu at a certain potential. The preconcentrated Cu was firstly reduced at a certain potential and then was determined by differential pulse stripping voltammetry.

采用电化学方法在pH7.0磷酸缓冲溶液中，将邻苯三酚氧化电聚合制成稳定的水不溶性膜修饰在玻碳电极表面，将制得的膜修饰电极在一定电位下选择性预富集铜，并用差分脉冲溶出伏安法测定。

Replacing premodification with postmodification in English language can weaken the disabilities attached to personality.

在英语中，用后修饰语取代前修饰语的形式，能够弱化人格的残障属性。

In Chinese, premodification is normally used while postmodification is rarely used.

汉语一般使用前修饰语，不使用后修饰语。

The premodification structure of expressions about human disabilities labels or defines the whole personality be a kind of 'disabled person', automatically giving prominence to the attributes of disabilities and negatively influencing our cognizance of personality with disability or handicap.

表达&残障属性&的前修饰语结构，把被修饰的整个人格标注为或定义为特定的&残障人&，自动突出了人格的&障碍&、&残疾&属性，消极地影响人们对有残障属性的人格的认知。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
