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。

Objective To study the pathogenesis and clinical symptoms of patient with central type of interˉvertebral disc protrusion manifested intermittent claudication as the mainly clinical presentation,so as to reach the early diagnosis and treamtmet in time.Methods In58cases,X-ray film,lumbar discography,CT examinations were done to confirm the diagnosis,then total laminectomig was performed to reveal the vertebal body without involving small arˉticular process.Intervertebral tissue was excised via duralotomy approach in2cases in remaining56cases,through right and left longitudinal syndesmotomy to resect the nucleus pulposus of lumber intervertebral disc.Results In58cases treated by operation,the operative findings were in according with the X-ray and CT examinations ofpre-opˉeration.
