Like racing cars that swerve and hit each other on a circular track, the moons' speed relative to each other is low because they travel in nearly the same orbit.
这有点像是突然转向的赛车在环形赛道上相撞，月亮们也在同一轨道公转，所以他们之间的相对速度很小。
Vortex-induced vibration is limited amplitude response, but it occurs at low wind speed with relative large amplitude, which will affect the strength and fatigue resistance of the structure.
尽管涡振是一种限幅振动，但由于其发生风速较低，振幅相对较大，会影响结构的强度和疲劳，因此大跨度拱桥的涡振响应研究具有重要的意义。
The vortex shedding vibration will take place at the relative low wind speed because of arches blunt section.
并且，钝体截面的主拱在低风速下容易产生涡激振动。
The high compacting speed enables P/M parts to have higher properties and the possibility to make large P/M parts at relative low cost. A high potential in the broad application of HVC is expected.
其压制速度快，可使材料性能更加优良、生产更加经济化，具备用中小型设备生产超大零件的能力，具有广阔的应用潜力。
Its speed relative to the vertical conveyor is low, mainly used for horizontal or small Angle transport materials, transport distance is generally not more than 70 meters.
其转速相对于垂直输送机要低，主要用于水平或小倾角输送物料，输送距离一般不大于70米。
The utility model aims at providing an efficient and energy-saving DC brushless refrigeration compressor motor with controllable rotating speed and relative low cost.
目的是提供一种高效节能、转速可控，成本又较低的直流无刷制冷压缩机电机。
The regions of low speed development and the B regions of match mode on the relative carrying capacity of resources have a very good coupling.
低速增长区和过渡区大部分则与相对资源承载力匹配模式的B类地区具有很好的耦合。
