Both of the methods are critical to decrease the error of the slewing ring's ball track of grinding formation.

该方法是减小回转支承滚道磨削误差、提高滚道轮廓精度的关键技术之一。

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.

另外，提出了轨廓分区法全面计算轮轨接触状态法，在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下，可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量，以此来判断轮轨的真实接触状态：正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮，并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力，从而使仿真结果更接近于车辆在实际线路上的运行状态。

Roller outer surface of the bus is basically a straight line, and with the roller axis line intersecting, usually truncated cone.

滚子外表面的母线基本上是直线，并与滚子轴心线相交，一般为截圆锥体。

And a screwy algorithm based on digital image from mono-view is presented. This algorithm needs the four-region sign with the screwy boundary labeled on the surface of columniform targets. Then the length of the intersecting lines of the object's axis and the screwy boundary are gained by means of digital image processing, such as gray histogram balancing, Susan edge detection and Hough transform. Finally, the object's rolling angle is accurately gotten in shooting range.

该方法通过在圆柱形目标表面涂上边界为螺旋线的四区域标志，综合运用直方图均衡化、Susan边缘检测以及Hough变换等数字图像处理技术，从光测图像中得到各个时刻目标中轴线与螺旋线的相交线段的长度，由此可高精度测出空间目标的滚转角，从而有效地解决了靶场试验中空间目标滚转角的测量难题。

According to the calculated result, the metal flowing law, von Mises stress and the formed outer diameter of involute spline were forecasted; also the errors between the simulation result and the object dentiform of involute spline were analyzed.

根据数值模拟的结果，讨论了齿形误差及其成因；揭示了滚轧过程中金属流动规律和应力变化情况；分析了冷滚轧前轴坯直径与成形后花键最大外径的关系，提出了轴坯直径的修改建议。

Pan joined lard and ginger juice, wine, water, first remove the nests waiting for a minute roller, and the people of Dictyophora, mushrooms, chicken roll cook until chicken cooked wheat after the release bowl, adding bird's nest ham silk.

锅加入猪油、姜汁、料酒、水，先将燕窝下锅滚片刻捞出，放人竹荪、香菇、鸡肉滚煮，待鸡肉熟后倒出放人碗内，加人燕窝火腿丝。

Needle roller bearing of the rigid because of its small and roller diameter than tapered roller bearings are much better, and the development of double row bearings company disnature rigid needle roller bearings so that it can be used with copper sleeve bearing.

滚针轴承的刚性因其滚子直径小而给比圆锥滚子轴承好好多，而且轴承公司斥不天的单列错位的滚针轴承使其刚性可以与铜套滑动轴承相媲美。

The ball went distally instead of to himself,opposite to his wish.

与他的愿望相反的是，那个球不是朝他滚来而朝远处滚去。

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

研究结果表明：集装箱平车以160 km/h的速度与动车组等速交会时，在隧道内会车时车载集装箱中部压力变化幅值是在明线会车时的3.46倍；在明线和隧道内会车时，集装箱列车受到的侧向力和侧滚力矩均与交会列车运行速度近似成平方关系；因隧道内压力分布一维特性较强，集装箱平车交会侧与非交会侧压力相差并不大，因此，在明线会车时集装箱平车受到的侧向力和侧滚力矩均比隧道会车时的大，大约是其1.1倍。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
