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。

So to speak, control high-income groups strictly , reduce low-income groups strugglingly and develop middle-income groups vigorously.

最后，针对收入分配差距影响经济增长的两个环节，提出解决我国的收入分配差距问题要从减少现存的收入差距问题和提高政府的转移支付效率入手，严格控制高收入群体，努力减少低收入群体，大力发展中间收入群体。

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。

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。

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

特别是，最近邻格点之间的跃迁积分的变化与碳纳米管的曲率紧密相关，因此实际上，理想金属型 zigzag 碳纳米管本身具有微小能隙，而施加比 armchair 碳纳米管小的多的压缩量，就可以使金属型 zigzag 碳纳米管在费米能处打开相当的能隙。

Reformed surgery had the following features: We firstly resected the uterus and then dissected the pelvic lymph node. Urinary bladder gap and rectum gap were opened. After exposing the route of ureter, we excised the uterus artery at the point between the ureter and the uterus artery. Cardinal ligament and uterosacral ligament were cut off by electric knives.

However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.
