Under the base of it, also considering the characteristics of the multi-channel multistage rimfire gas switch, much study and experiments of the surface flashover along the PMMA insulator and the PMMA housing of the switch were done. Following conclusions were drawn: After introducing PMMA insulator among the board electrodes, the voltage of the discharging of the SF6 drops by 30%. With increasing of the pressure of SF6, voltage of the discharging descends more sharply. With PMMA spacer, the dispersing of the discharging voltage of the gas gap increased as compares to the unbridged gap, such increases in value of the discharging voltage become more obvious with the gas pressure increased.

本文对SF6气体中的沿面放电及影响因素进行了分析，在此基础之上结合边缘点火多级多通道气体开关的沿面绝缘结构特点，经过大量理论分析和电场计算，对有机玻璃支撑绝缘和有机玻璃外筒进行了沿面放电研究，研究结果表明：板电极间SF6气体间隙引入有机玻璃绝缘子后，间隙放电电压平均下降约30%，随气压增大放电电压下降趋势增大，引入有机玻璃绝缘子后放电分散性明显增大，随气压增大，放电分散性呈增大趋势。

Methods: 7 calf lumbar spine specimens (T13~S2) were biomechanically tested under pure moment of 10Nm loading with Tenor pedicle screw system as the fixation device. Range of motion and intradiscal pressure were measured in all unfused segments and compared among the control group, the single-segment-fixed group (L45) and the double-segment-fixed group (L3~L5), and the correlation analysis and comparison between the increments of kinematic index and intradiscal pressure were performed.

The numerical results show that:(1) the throughflow wake is considerably influenced by the tip clearance. The low-kinetic-energy fluid accumulated in the shroud/pressure side of the unshrouded impeller, but in the shroud/suction region for 0.0 tip clearance;(2) there possibly exists an optimum size of the tip-clearance which is not the zero tip clearance to make the flow loss minimized.

研究结果表明，(1)NASA低速大尺度离心压缩机半开式叶轮的低速尾迹区在压力面与轮盖的角区，而相应的闭式叶轮的低速尾迹区聚集在轮盖的中心位置；(2)数值实验表明，叶顶间隙并非越小越好，可能存在一个最优间隙，使得叶轮流动损失最小。

Gap acceptance theory is one of calculating the capacity method of unsignalized intersections. Both Critical gap and follow up time play great role in that method.

间隙接受理论是计算公路无信号交叉口通行能力的主要方法之一，临界间隙和随车时距是其中2个重要参数。

On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.
