The separation is based on the differential migration of the micelle and the surrounding water and the differential distribution of the solute between the mi celle and aqueous phase,therefore,the separation mechanism is very similar to th at of micella electrokinetic chromatography.

这种分离方式是基于胶束和水相在色谱过程中的不同迁移以及溶质在胶束和水相间的不同分配而实现的，其分离的机制与胶束电动色谱(mic ellar electrokinetic chromatography，MEKC)十分相似。

Differential On FWD cars, the differential unit is normally part of the transaxle assembly.

差速器 在前轮驱动车辆上，差速器装置是变速驱动桥上常见的装配。

Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.

首先根据构造的移动最小二乘曲面计算采样点的表面几何属性，然后根据协方差分析确定点元在其切平面上的椭圆表示，最后采用椭圆加权平均滤波从远到近单遍绘制各点元，此外，根据表面几何属性确定点模型的轮廓线，实现了点模型的非真实感绘制。

Some conclusions are drawn as follows: The total tendency of socles is basin-shaped settlement which is bigger in the middle position socles than the peripheral position socles before the pile foundation underpinning. Pile foundation underpinning augments the differential settlements. After soil excavation, middle position socles rebound obviously owing to unloading action, which lessens the differential settlements between middle and peripheral position socles.
