极性

In order to examine the electroviscous effect of polar fluids on the friction factor for the laminar flow in microchannels, the numerical investigations were conducted, and the results were compared with the experimental data available in literature.

采用数值模拟方法确定极性流体电黏性对于微通道内流动摩擦系数的影响，并与文献中的实验结果进行了比较。

The numerical simulation results indicate that whether the electroviscous effect should be considered is determined by the ratio of channel hydraulic diameter to the Debye thickness. Smaller ratio leads to greater electroviscous effect.

数值模拟结果表明：极性流体电黏效应的影响是否可以忽略，要根据通道当量直径与双电层厚度的比值r来决定，比值越小电黏影响越大。

It was found that exogenic gene could start-up the expression of neural stem cell specific marker, nestin, and raise neural polar changes on ES cell.

发现外源性ibeB基因的转染能启动ES细胞表达神经干细胞标志蛋白nestin，并使ES细胞发生神经细胞样极性变化。

The fatty acid synthetase inhibitor is extracted from fleeceflower vine with polar organic solvent and/or water, preferably 40-60 % concentration ethanol solution.

本发明的脂肪酸合成酶抑制剂是用有机溶剂或水或有机溶剂与水的混合物，从中药首乌藤中萃取出的物质。所述的有机溶剂为极性有机溶剂，其中，优选的是乙醇，最优选的是20％-70％的乙醇，更优选的是40％-60％的乙醇。

The study of coal wetting heat effect, zeta protential and adsorption of frother on coal/water showed that the frother is of collecting performance again.

研究表明，煤炭浮选非极性捕收剂对起泡剂的起泡性能具有显著的影响，具体效果与化学组成、浓度及配比有关，这一点对于煤炭浮选用药具有重要的意义。

The S type of CMS is a gametic sterility type, and its pollen sterility was considered to be associated with the expression of R region in the mitochondria.

其中两个含有完整R区的BamHI片断已被克隆测序，结果表明在这两个片断中cox1和cox2分别位于R区上游，但与之位于不同的极性单链上。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

The asymmetric esterification of glycidol catalyzed by lipase was carried out in a nonaqueous medium. The effect of the replacement of water necessary for the function of lipase with water-mimicking solvent on the resolution was investigated.
