Tracking relative motions within the volume , though , is tough ; it requires distance and velocity measurements of high precision 在本域中，要追踪星系的相对运动仍十分困难，因为在距离和速度的测量上，需要很高的精准度。
Also , the motion between the earth and the platform , atmosphere disturbance and so on make the images blurred and degraded 另一方面，由于光照大气及平台和地球之间的相对运动，也使成像产生模糊和降质，降低影像分辨率。
In general , the force opposing motion is slightly greater before one surface starts moving over another surface than after movement has started 一般来说，在一个平面开始移动之前这种相反的力会比较大，而相对运动后就不那么大了。
When two gear do relative motion , one drives the link to one direction , the other one drives the link to reversed direction 两个齿轮做相对运动时，小齿轮利用齿轮的部分推动杆子往一边，另一个小齿轮也利用齿轮的部分推动杆子往反方向。
In addition , relative motion between flying - around satellites is analyzed and formations of non - flying - around case and complex case are discussed 另外，还分析了绕飞编队中环绕卫星间的相对运动，讨论了几种非绕飞编队以及复杂构型的编队。
Considering an engagement in space terminal intercept , the analytical solution of the equations is obtained in closed form through valid linearization 考虑空间末段拦截的具体情况，在相对运动方程进行线性化处理的基础上可以得出运动方程的解析解。
The extracting method of the relative velocity , the miss distance and the miss time parameters of the target in miss - distance measurement system is investigated 摘要研究了脱靶量测量系统中靶弹的相对运动速度、脱靶量、脱靶时刻等参数的提取方法。
The process and parameters are also be applied to the surface treatment of the push rod in hydraulic mechanism , where there is relative motion between push rod and seal 该工艺及参数也适用于推进杆与密封圈有相对运动的液压动力机构对其推进杆表面的处理过程。
This system plays an important role in the relative movement between the west pacific plate and eurasian continental plate . thus , the paleozoic structures had been modified 此断层系列对于西太平洋板块与欧亚板块之间的相对运动起重要作用，于是古生代构造带被改造。
The slides and slideways of a machine tool locate and guide members which move relative to each other , usually changing the position of the tool relative to the workpiece 车刀与车刀作相对运动，车刀的滑块和滑道用于对各车刀进行定位和导向，通常也可改变车刀与工件的相对位置。
