Based on the background information on the part of the existing strategy adopted by the Beijing Gas Group, this paper conducts a detailed analysis of strategic issues of this group company by using such analytical tools as SWOT Matrix, Boston Matrix and Portor's Five Forces Model. The author discusses the status in quo of global gas market and domestic market, the internal environment of the group company, and the structure of gas industry. The major strategic problems of the group company are summarized on the basis of above-analysis, including the obsolete thoughts of decision makers, the weak management system of human resources, the deviation on building corporate culture, and the teetering on information processing.

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。

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.
