The methodology to perform friction force microscopy experiments for contacting brushes is presented: Two polymer brushes that are grafted from (a) substrates and (b) colloidal probes are slid to show that, by using two contacting immiscible brush systems, friction in sliding contacts is reduced compared to miscible brush systems.

本书根据作者多年来在叶轮机械与流体力学相关领域的积累和研究成果提炼而成。主要内容包括流体基本属性、基本方程组的推导、网格生成的代数法与微分法、网格量的计算、模型方程的分类及求解特征、差分及其稳定性分析、有限体积法的基本原理、不可压缩N-S方程的离散计算、边界条件的实施、代数方程系统的迭代法、动-静子耦合流动模型与算法，以及并行编程基础等。本书注重理论体系的完整、系统和实用性，将抽象的理论与具体实例相结合、数理基础与当前热点相结合，强调研究思路与解决方法的贯通，既可作为教学用书，也可供科研参考。

A novel optical polishing process, called “Convergent Polishing”, which enables faster, lower cost polishing, is described. Unlike conventional polishing processes, Convergent Polishing allows a glass workpiece to be polished in a single iteration and with high surface quality to its final surface figure without requiring changes to polishing parameters.
