In this study, we use Computer Aided Diagnosis Axiogragh recorded condylar movement of normal occlusion and Angle class two division one subdivision malocclusion with mandibular retrusion every twenty-five during mandible open and close, protrusion and retrusion, and medio-free movement. Then we analysis the deference in order to find out the characteristic of condylar movement of Angle class two division one subdivision malocclusion with mandibular retrusion and the change regularity among befor and after functional appliance treatment.

本研究以正常牙合和下颌后缩型安氏Ⅱ类1分类错牙合各25名为研究对象，采用髁突运动轨迹轴图描记仪(Computer Aided Diagnosis Axiogragh)记录其下颌在开闭口、前伸后退和侧方运动时髁突的运动情况，对比分析下颌后缩型安氏Ⅱ类1分类错牙合的髁突运动轨迹特征及其功能矫治前后髁突运动轨迹的变化。

A non-singular single integral mathematical model is adopted to calculate the external intermittent and alternative longitudinal magnetic field acquired by single axisymmetrical and cylindrical hollow coil t which is coaxial to electrode and excitated by a revisable pulsed current of square wave t in austenitic stainless steel GTA welding.

针对奥氏体不锈钢外加纵向磁场的气体保护钨极电弧焊接时，与电极同轴的单个轴对称空心圆柱线圈在双向脉冲矩形励磁电流作用下产生的间歇交变纵向磁场，采用无暇点单积分磁场的数学模型，对＊TAW焊接外加间歇交变纵向磁场进行了数值计算，该方法具有模型简单、计算速度快和精度高等优点并讨论了该间隙交变纵向磁场的分布、磁场的均匀性及其纵向分量与径向分量的比率等规律及其对焊接行为的影响，认为横磁分量将削弱GTAW外加纵向磁场的有利作用，影响磁控电弧的焊接质量

The strength degradation of single crystal sapphire is mainly attributed to the rhombohedral twinning via c-axis compression.

白宝石高温强度的降低主要是由于c轴方向受到压应力时产生r面双晶所引起的。

Firstly, this paper based upon coordinate transformation in vector space, the resolution principles of ship's swinging in three rotative axes of a hull – mounted array sonar are developed. The analytical results are used as the rules to control and stabilize the attitude of the array sonar so as to isolate the swinging of the ship.

本文首先根据矢量空间坐标变换的原理，分析了船舶摇摆运动在声纳基阵转动轴上的分解原理，得出了控制和稳定声纳基阵姿态不受船舶摇摆影响时所需的控制规律。

Shafted,standard version A,the sum of the pressure at ports A and B may not over 70

当承受脉冲载荷压力超过32MPa时，我们建议使用标准的A型花键轴，A

Yes! if every business card printing and membership card production unit and after every post processing unit in using AC servo shaftless, there would be no more than those.

是的！如果每一个制卡和会员卡制作单元和每一个后加工单元在采用交流伺服无轴传动时，就没有以上所阐述的问题。

Business card printing and membership card making adopts shaftless, servo-motor and business card printing and membership card making roll direct connection when changing the product is only required to enter a password in the man-machine interface business card printing and membership card to make up for long.

制卡和会员卡制作部分采用无轴传动，伺服电机与制卡和会员卡制作版辊直接连接，在更换产品时只须在人机界面上输入制卡和会员卡制作周长。

Machine is started; the skiving spindle turns when the safety door is closed and the start pedal item

确保机器开始后，剥胶心轴转动时，安全门关闭并开始踏板是按下的。

When the turn-table slewed, the hydraulic motor transmitted power output which enabled pinions on the output shaft to revolve.

进行回转时，液压马达输出动力，通过回转减速器减速后带动输出轴上的小齿轮旋转，小齿轮与回转支承的齿圈啮合，由于回转支承的齿圈与车架刚性连接，因而回转减速器带动与之相连的转台回转。

The table base with the table backand forward is Y. The spindle head going up and down is thedirection of Z axis feed. The Z motor takes with brake. when thepower is cut off, the motor stops in order to prevent the spindlehead fall down because of self-gravity.

工作台底座带工作台前后运动为Y轴方向。Z向进给为主轴头的上下运动，并且Z向电动机是带制动器的，当断电时，Z向刹紧，以防主轴头因自重而下滑。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
