轨道速度

The influence of train running speed, wheel-rail friction coefficient, vehicle load, track geometric irregularity, partly load, gauge and the shape of wheel tread on derailment was emphasized.

论文重点分析了车辆运行速度、轮轨摩擦系数、车辆载重、轨道几何不平顺、偏载、轨距大小、车轮踏面形状等因素对脱轨的影响。

He returned to the front in 1918, taking an inch-thick diary to record what he saw.

日记的厚度减慢了子弹的速度，使得子弹偏离了轨道。

Experience up to 4 G's as you are propelled at 50mph through 4 inversions.

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

作为星球内航空器，女妖不需要大马力的引擎来脱离周转速度或在星球轨道上作战，因此技术人员安装了两个经济型的涡轮风扇发动机取代引擎。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

设计师们为女妖战机量身打造了一套经济型双涡轮喷射引擎，因为作为只在行星大气层内作战的飞行器，其并不需要高性能的引擎来达到在既定轨道战斗所需的能量以及逃逸时所需的速度。

This system works with straights and arcs, as opposed to splines, for a fast and accurate method of laying down track.

这一系统使用直轨和弯道来代替花键以提高轨道铺设的的速度和精确性。

Passenger flow models for walkway, upward stairway and downward stairway which illustrate passenger speed/density relationships have been built using statistical method based on the collected data at different types of passenger facilities in urban railway transit hubs.

然后针对北京市几个主要轨道交通枢纽进行了大量乘客交通流数据的观测和采集，建立枢纽内进站通道、出站通道、换乘通道、上行楼梯和下行楼梯处的速度-密度关系的交通流解析模型，得。。。

Supply and demand contradictions, the transport volume, high-speed rail track traffic

供求矛盾突出，大运量、高速度的轨道交通脱颖而出

It can be seen from this article that the two methods have demonstrated the working capacity for calculation of frictional force and thermal load on surface of a hypersonic winged flight vehicle, which moves in dense atmospheric layers on a trajactory with stationary values of velocity head.

由文可见，对于在稠密大气层内，沿轨道运行头速度恒定的高超声速有翼飞行器，能够用本文所采用的两种方法计算其表面摩阻和热载荷。

The effective distance of measuring device on vehicle is from 5mm to 25mm. Through the simulation tests, if the space of track mark is 0. lm, the instrument can measure the speed ranged from 0 to 600km/h with an accuracy of ±0. lm/s.

对车载测速仪，其有效作用距离为5mm-25mm，经模拟测试，若轨道检测标志间距以0.1m计算，测量速度范围为0-600Km/h，测量精度为±0.1m/s。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
