X6 3?,large specific surface area and adsorbent capacity However,most molecules and hydrated ions can not enter the aperture pass because of their size over the aperture diameter of palygorslote except less simple ones Furthermore,Palygorskite adsorbs water molecule choosingly In most cases the absorbing of palygorskite is by its outside surface that works in the form of colloid and ion exchange other than i...

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。

This may be overcome, as suggested in the present investiga- tion by assuming that the vicinal actions are due to the interactions of various chemical bonds in the molecule with the chromophoric electron.

指出旋光度應由分子中各化學鍵，而不是分子中各原子對於生色團電子的微擾作用來計算，兩者的主要不同點在於是否考慮鍵的多極矩。

The molecule has a typical D-π-A structure with terminal units of electron donor and accepter groups. The triphenylamine group, as the electron donor, is connected to the oxadiazole group which is the electron accepter through the cinnamene group.

该分子具有典型的D-π-A型推拉电子结构，三苯胺基团作为给电子基通过苯乙烯共轭链桥接到吸电子基1，3，4-恶二唑基团。

The dissertation is focused on the research of organic supramolecular self-assembly and molecule folding. It consists of four parts. In the first part, three new model molecules for investigating intramolecular coaggregation behavior have been designed and synthesized. Fluorescence studies reveal that intramolecular coaggregation of these molecules take place with the increase of the solvent polarity because of hydrophobic-lipophilic interaction .

本论文主要对有机超分子自组装和分子折叠做了一些研究，共分四个部分：第一部分中，我们设计并合成了一个新的研究分子内自簇集的模型，用荧光光谱法对该模型进行了研究，研究表明，在促簇能力较强的溶剂体系中，这一类模型分子可在疏水亲脂作用的驱动下发生分子内自簇集而形成卷曲的构象。

The CA125 is an epitope on a large mucin glycoprotein molecule of greater than 1 million Daltons,normal expressed on the coelomic epithelium,including ovarian surface.By now,CA125 assay has been used for monitoring response to primary treatment,detecting clinically occult ovarian cancer at the time of recurrence,as well detecting primary disease in early stage.The CA125 level is abnormal in over 90%of advanced stage ovarian cancer,but it is not increased in about 50%of the patients with stageⅠdisease.

卵巢癌肿瘤标记物中最常用的是CA125，它是体腔上皮正常表达的一种抗原蛋白，晚期卵巢癌中，超过90%病例CA125升高，而在Ⅰ期卵巢癌中，大约有50%病例CA125正常，因此血清CA125敏感性和特异性不能满足筛查指标的要求。

Each chromosome is made up of a tightly coiled strand, a molecule of DNA.

每一个染色体是由一个紧紧缠绕链，一个分子的DNA 。
