The adsorption behavior of polydisperse polymers at solid-liquid interfaces was studied by the method of Monte Carlo simulations based on the lattice model, and effects of the polymer chain length in systems of both average and normal distributions on the adsorption layer thickness were evaluated.

在格子模型基础上用MonteCarlo方法模拟研究了多分散高分子在固液界面的吸附行为，重点考察了平均分布和正态分布两种不同链长分布形式的高分子在固液界面吸附层厚度的分布规律，模拟结果与概率统计模型计算的吸附层厚度分布趋势一致。

One analyst says Google is well on its way to establishing itself as the first port of call for academic researchers, although it does not yet represent a threat to Reed Elsevier's Scopus, a full text-linking abstract and indexing database.

一位分析师表示，Google正使自己成为学术研究员首先光顾的地方，虽然它尚未对Reed Elsevier开发的 Scopus构成威胁。Scopus是一个完整的文本链接摘要和索引数据库。

Terminal oxidative inhibitors, such as KCN, Salicylhydroxamic acid , antimycin A and NaN〓, can cut off electron transport chains of cytochrome pathway and alternative pathway, marked decreased BADH protein levels. Oxidative phosphorylation uncoupler 2, 4-dinitrophenol had a similar negative effect on BADH gene expression, and exogenous ATP and ADP increased the BADH levels. These results, in conjunction with the terminal oxidation results, indicated that ATP could be a critical component in BADH gene expression.

2.2 末端氧化抑制剂KCN、SHAM、抗霉素A和NaN〓能打断呼吸链，阻断电子传递，使BADH蛋白的表达量明显降低，说明末端氧化同样参与BADH基因表达的调节：末端氧化影响基因表达的实质就是ATP的影响，线粒体磷酸化解偶联剂DNP明显降低BADH蛋白的含量，而外源的ATP和ADP对BADH基因表达的正效应作用最大。
