查询词典 speed limit

An "unround" or eccentric wheel is alleged to have led to wheel tyre failure of a German ICE at Eschede in 1998, causing a high-speed crash with heavy loss of life. The wheel is alleged to have had an eccentricity (difference between major and minor axes of the ellipse) of 1.1mm, against a limit of 0.6mm.

据称，1998年在德国Eschede发生的ICE列车高速碰撞，就是因为车轮不圆或缺陷造成车轮轮箍故障引起的，事故造重大伤亡。

When diesel/CNG dual-fuel turbocharge intercooling engine D6114 runs in dual-fuel mode, only diesel fuel is supplied when starting and idling, and when engine speed is beyond the preset value,electronic control system send out command to limit diesel fuel injection amount,and natural gas begin to enter into cylinder through mixer to take part in burning, at this time small a mount of diesel fuel shall play mainly a role of ignition,and engine load is changed by altering natural gas supply amount.

D6114柴油/CNG双燃料增压中冷发动机当以双燃料方式工作时，发动机起动和怠速只燃用柴油；当转速超过某设定值，电控系统发出指令限制柴油的喷油量，天然气经混合器进入气缸参与燃烧，此时少量柴油供给主要起引燃作用，发动机负荷变化则通过改变天然气供给量的大小来实现。

When you want to spinning the yarn which slubby length and space is very short,such as slubby length+slubby space≤5cm(the wide is double,it is longer when the wide is wider),the speed of the front roller is limit to not more than 200 rpm.

对于纺一些节长、节距都很短的竹节纱，也就是节长+节距≤5cm(指的是粗度2倍，如节粗更粗，相应长些)的情况下，限制要求为前罗拉速度不能大于200转。

Results indicate that radial distance of the bushing from the rotor center and the radius of the hemispherical bushing significantly affect wear rate,and minimzing both two values will result in lowest wear for micro-rotor systems in MEMS.However,it is noted that the bearing radius sets a lower limit on the hemispherical bushing radius since the bushings are located beyond the rotor inner radius.It is desirable to reduce their effects on friction and wear on micro-rotors by regulating the radius of the bushing and the radial distance of the bushing from the rotor center within permissive range of micro-fabrication.Severe wear exists with increasing applied load and rotating speed of the rotor.Stress distributions in the contact region are different from Hertz solutions due to the convergence stresses apearing on the uncontinuous curvature line and the contact pressures display symmetrical parabola in the contact region.

结果表明：在MEMS微转子系统中，微转子轴衬偏心距离和转子轴衬半径影响线磨损率，以两者减至最小为较理想，但须注意设计中轴承半径的限制，并使轴衬偏心距离大于轴承内半径；在转子加工制造许可的范围内，可以通过调整转子轴衬的半径和偏心距离来减少摩擦磨损对微电机的影响，随着转子所承受载荷和转子旋转速度的增加，其磨损严重；接触区的应力分布不同于经典Hertz解，这是由于应力集中出现在不连续的曲率线上，且接触区的接触压力呈现轴对称抛物线状分布。

These factors limit the rigidity and thickness of overlays, speed of operation and ease of use.

这些限制了涂覆层的刚度和厚度、操作速度以及易用性。

There are very very very few people like me willing to push the limit in such a fashion. I vividly remember once I held a camcorder and video-taped for two minutes in freezing condition while skiing at high speed. My fingers were so frozen that I had to go straight to the ski lodge in order to warm them up.

非常少的人会像我一样，愿意用这样的方式来推向极限，我清楚记得有一次，我在高速滑雪时，握著摄影机在冰冻的情况下录影二分钟，我的手指头都弄冻僵了，而必需直奔到滑雪小屋将它们弄暖。
