And adsorption of jack bean proteins onto the amphoteric resin was studied in this paper. The amphoteric resin was in innersalt form. The results of adsorption experiments show that when the proteins are adsorpted into the amphoteric resin in the neutral phosphate buffer solution, the diffusion coefficient of protein is near twofold in 0.4 mol/L NaCl phosphate buffer solution than that in solution without salt, and the adsorption capacity of protein also rises at the same ti...

通过盐浓度对吸附的动力学和热力学影响的研究，结果表明，在中性磷酸盐缓冲液中，两性树脂吸附刀豆蛋白，有盐( 0 。4mol/L Na Cl)的比无盐的扩散系数提高将近一半，且吸附量增加，其吸附等温线的效率在最初始部分高于无 Na Cl时的；随着盐浓度( 0～ 1 mol/L Na Cl)的提高，树脂对蛋白的吸附量也变大，盐浓度提高时树脂膨胀体积的增大与蛋白吸附量的增加呈线性关系，内盐型两性树脂对大分子蛋白质的吸附作用与小分子高价离子的相似，同样是通过内盐键破裂吸附。

After a century, the kinetic theory of gases was also won the rapid development of .1857, the Clausius for the first time clearly statistical concepts, derived gas pressure, volume and temperature inter-correct relations, but also in 1858 introduced the concept of .1859 free path of molecular motion, the Maxwell velocity distribution law is derived, established the mathematical theory of transport processes .1868, the Boltzmann velocity distribution law was introduced in the gravitational field .

此后一个世纪，气体动理论才又获得飞跃发展。1857年，克劳修斯第一次清楚地说明统计概念，导出了气体压力、体积和温度间的正确关系，还于1858年引入分子运动自由程概念。1859年，麦克斯韦导出了速度分布律，建立了输运过程的数学理论。1868年，玻耳兹曼在速度分布律中引入重力场。

In the point of view of interacting forces among micro-particles in liquid pure substance and according to argon model and theorems and rules in semi-metal structure theory of organic molecules created by one of authors, a new theoretical equation of the liquid molar volume V at the normal boiling point to pure substance is proposed.

The 0°K relaxed structures of grain boundaries in Cu and its alloys (Cu-Ag, Cu-Bi) were simulated with molecular dynamics method by using a five-parameter potential and constant volume assumption.In these cases, the results showed that the atomic distribution was periodic in the two directions paralled to the grain boundary and it was mirror-symmetric in the direction perpendicular to the boundary.

本文采用五参数对势和固定体积的假定，应用分子动力学方法模拟了零温下纯Cu、Cu-Ag和Cu-Bi合金的晶界弛豫结构，计算结果表明，在上述情况下，原子分布在平行晶界面的两个方向是周期性的，在垂直晶界面的方向是镜面对称的。

The specific imprinted sites could selectively rebind the template, resulting in the slower permeation of the template. And the size effect means that the smaller the size is, the faster the template transports.

特异性识别位点会选择性地识别模板分子，从而使其渗透速度减慢；尺寸效应主要体现在底物蛋白的体积越小其渗透越快。

Because of attraction between water molecule and carbonium ion, the severe contract in system volume brings about activation volume effect (the most negative A〓 observed in this work is 407cm〓mol〓), which produces subtle relationship between reaction kinetics and pressure in a certain operating region.

反应过渡产物正碳离子及水合正碳离子与近临界状态水分子之间强烈相互吸引导致反应活化体积出现极负值现象（本实验所测极值为-407cm〓·mol〓，这使得水解动力学参数对反应压力存在敏感依赖关系。

The contribution of electrostatic interaction to the transfer volumes is predominant. The reduction in the electrostriction with increasing the concentration of salts was confirmed by the decreased hydration number.

氨基酸两性离子端基和阴阳离子间的静电作用对迁移体积的贡献是主要的，静电作用削弱了两性离子带电中心对周围水分子的电致收缩效应，造成氨基酸的理论水化数随盐溶液浓度的增加而减小。

And the emeraldine salts (ES2) of polyaniline were prepared by emeraldine base form of polyaniline doped with different acid dopants at room temperature. The structure and morphology of ES1 and ES2 were characterized by Fourier transform infrared spectrometer, Ultraviolet-Visible spectrophotometer and wide angle X-ray diffactometer, respectively.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
