Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

The long axis of the low intensity isoseism of this earthquake is NW-trending, indicating the effect of the NW-trending west Wuyuan Fault.

包头西6.4级地震高烈度区等震线长轴呈NE向，与乌拉山北缘断裂接近，该断裂是包头西6.4级地震的发震构造。2次地震高烈度区长轴与低烈度区长轴走向相差近90 ，这是因为除发震构造外，烈度区还受一组与之交会的共轭断裂活动的影响。1989年大同-阳高6.1级地震，发生在从六棱山腹地向大同-阳高盆地延伸的NNE向大王村-西要泉断裂上，该断裂是大同-阳高地震的发震构造。

The product nearly can be applied to all fire occasions. For vertical turbine fire pump, it's suction immerges into water, the maximal suction height is 30m, it start up rapidly and run reliably. Especially it is suitable for engineering places that water level is below pump installation foundation such as docks, ocean platform, and so on.

立式长轴式消防泵采用独特的立式长轴结构，泵吸入口淹没于水中，泵安装面距液位高度最大可达30m，由于不存在引水问题使得可靠性大大提高，尤其适用于码头、海洋平台等消防水液位低于泵安装面的工程场所。

RESULTS: After root canal preparation, the mean value of the angles of canal curvature decreased from 36.21° to 21.98°, while the mean value of the radius of the canal curvature increased from 6.25mm to 11.35mm; the canal axes transported and intercrossed with the original axes at 2 points and created 3 intersection zones.

结果：根管预备完毕，根管弯曲角度均值从预备前的36.21°逐渐减小至21.98°，弯曲半径均值从6.28mm增大至11.35mm；根管长轴发生了偏移，与预备前原根管长轴形成2个交点，3个相交区。

Because of the secular perturbation variations of the ascending node right ascension, the argument of perigee and the mean angle caused by the initial deviations of the semi-major axis, the inclination and the eccentricity are linear time-variant, then the active biases of the semi-major axis, the inclination and the eccentricity can realized the self-stabilization design of the elliptical orbit satellite constellation, and so the configuration stability will be improved.

通过初始偏差对椭圆轨道卫星的长期影响分析可知，轨道半长轴、倾角和偏心率的初始偏差对升交点赤经、近地点幅角和平近点角的长期摄动变化是线性的，因此通过主动偏置轨道半长轴、偏心率和倾角能够实现椭圆轨道星座构型的自稳定设计，从而提高其构型稳定性。
