The experiment shows lower surface tension and the emulsification of the complex is equivalent to OP-10 on rape oil and better than OP-10 on transformer oil.

结果表明，复配后的体系有较低的表面张力，对菜油的乳化性与烷基酚聚氧乙烯(10)醚相当，对变压器油的乳化性优于烷基酚聚氧乙烯(10)醚。

The oxygen transfer theory,can't be used to predict the reaeration coefficient of the rivers due to some undetermined parameters such as liquid film thickness ,the mean time of travel,surface renewal rates.

氧传质理论因存在不确定的参数(象液膜厚度，旋涡在界面的停留时间，表面更新率等)而不能用来预测河流复氧系数。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

HCV NS3C/NS4 protein fused with E. coli thioredoxin was expressed insolubly although thioredoxin is a highly soluble fusion partner. NS5B-dc21 protein was soluble, which is a truncated version of NS5B, while NS5AB protein was insoluble, which needed resolubilization and refold procedures.

HCV NS3C/NS4蛋白是以硫氧还蛋白融合表达的方式获得的，尽管硫氧还蛋白有很强的助溶作用，该蛋白依然不可溶形式存在；NS5B—dc21蛋白通过C末端疏水序列的删除，获得了可溶表达；NS5AB蛋白以不可溶形式表达，需要复性。
