The emission of N_2 in discharge gap is detected using optical emission spectrophy. The discharge reactor was put in lightproof box to avoid the disturbance from outside lights. A small hole was drilled in one sidewall of the box, and the fibre was mounted coupling to the inlet (1mm) into the hole. A tube with the inner diameter of 1.1mm was set in the front of the hole. In this way, only the light from a certain direction emitted from the discharge reactor could transfer into the inlet through the tube. The reactor could be moved in the vertical direction of the fibre, and the spectrometry can collect the total emission along the fibre inlet in single-shot measurement.

利用光学发射光谱仪对多针对板电晕放电中放电间隙内的N_2发射光谱进行测量，放电反应器置于暗箱中以避免外界对光谱测量的影响，将光谱仪的光纤耦合入口固定在暗箱侧壁的小孔内，小孔孔径为光纤耦合入口直径，在小孔前方安装孔径为1.1mm的细直管，只采集与光纤耦合入口在同一直线上的发光，避免放电区其它区域的发光被同时接收。

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.

这可以提高轴承的刚度，和主轴精密的径向引导，对于特别的运用，密排的圆柱滚子轴承被运用，圆柱轴承的图样在图。20和1.21展示圆柱滚子轴承图样由挡边的不知来区分，图样NU(图1.21b)在外圈有两个挡边，内圈无挡边，在图样N中内圈有两个挡边，外圈无挡边，图样NU和U所示的圆柱滚子轴承可制作浮动轴承因为滚子能够在轴向无挡边环上自由的移动，圆柱滚子轴承NG在外圈上有两个挡边，内圈上有一个，它们能够在某个方向上承受轴向力，图样NUP（图1.21d）被用来安装在一个保持经常扭转轴向力的固定轴承上。

文章针对本科定向生的教育特点，在《机械设计基础》课程教学中，就如何培养定向采煤专业学生的技能，从课程体系、教学方法、教学手段和实践创新等环节提出了一些改革措施，并进行了实践。

Based on the analysis of the geological tectonics setting and deep seated geophysical characteristics, the causative structure of the Yongdeng M S 5.8 earthquake on July 22, 1995 has been determined by the synthetical study of the faults in the earthquake area, focal mechanism solution, focal depths, meizoseismal region direction, post earthquake distribution, earthquake fissures and ground motion direction.

在分析地质构造背景和深部地球物理特征的基础上，通过对震区断裂构造、震源机制解、震源深度、极震区展布方向、余震空间分布、地震裂缝和地面运动方向的综合研究，确定了1995年7月22日永登5.8级地震的发震构造，探讨了形成该次地震的构造力学机制问题，认为该次地震是在局部构造应力直接作用下导致窑街—周家台隐伏断裂重新活动的结果

The position changes of mandibular molars were measured from mesiodistal direction and vertical direction, and the implant anchorage loss was evaluated by maxillary central incisor.

通过测量下颌第二磨牙在近远中方向、垂直向的位置变化，以衡量磨牙的位置改变。并通过下颌中切牙的位置变化，评价支抗强弱。

RESULTS AND CONCLUSION: The course of treatment was 10.4 months, and the velocity of mandibular second molar mesializing was 0.8 mm per month, with 8.5 mm in mesiodistal direction, there was no changes in the vertical direction.

结果与结论：疗程10.4个月，下颌第二磨牙平均移动速度为0.8 mm/月；平均近中移动8.5 mm，垂直向没有变化；磨牙长轴向远中倾斜角度为2.5°，下颌中切牙位置无改变。

"The helicopter went back and forth, flying over another group-in-hiding at mountain Phou Yeui," said Chue Chou Tchang. They called me and informed me that the helicopter was either a B8 or B12, which can load up to 50 people, and that helicopter flew 11 times back and forth, from the direction of village Na Khae to the direction of Muang Mek.

Also, Petrologic features, diagenesis and pore evolution features, and reservoir feature were worked and evaluated. The study direction of Neopaleozoic reservoir geology in this area was pointed out too.4.
