In this paper, based on the flexible multibody dynamics model of the virtual axis hybrid polishing machine tool, the differential — algebra hybrid equations is calculated by the Newton- Raphson method. The variety of the moving displacement, the velocity and the acceleration for the moving platform, leg, slider on the 3- PTT parallel mechanism and the pose curve of the series mechanism are obtained.

25°N——50°N，110°E——145°E一带大气环流(200hPa)的年际变化与华北相应各月降水的年际变化有显著的正相关关系：(25°N——50°N，110°E——145°E)一带200hPa位势高度正异常，华北相应各月降水偏多，反之，当为负异常时，华北相应各月降水偏少。

A hybrid method is proposed to study microcosmic characteristics of nanofluid multiphase flows in a lattice Boltzmann approach. Multicomponent lattice Boltzmann model on fine mesh is used in regions where physical parameters, such as density and velocity change tempestuously, otherwise a single component one on coarse mesh is used.

It indicated that the multiple-layered films were mainly composed by C-F, C=C and Si-O bonging, a little Si-C and Si-F bonding were also existed because of history effect. The bondgap were calculated as 2.7eV. The dielectric constant of the multiple-layered films was close relative to the thickness of the covering layer-SiOx, so the thickness had better be reduce. The bonding configurations of multiple-layered films had no evident changes after 400癈 annealing, the thickness raise very little and the dielectric constant increase 8%. Compared with one-layered a-C:F films prepared in the same conditions, the SiOx/a-C:F/SiOx multiple-layered films had a better thermal stability.

结果表明，多层膜主要由C-F，C=C，Si-O键构成，由于器壁的历史效应，薄膜中还存在少量Si-C和Si-F键；多层膜的光学带隙经计算约为2.7eV；多层膜的介电常数与包层SiO_x厚度有很大关系，应尽可能减小SiO_x厚度；在经历200-400℃的N_2氛围中退火后，多层膜的红外结构没有发生太大的变化：膜厚度稍微增大，介电常数只增加了8％，与同样制备条件下沉积的单层a-C：F薄膜相比具有较好的热稳定性。
