Examples
- Anchored navigation . you navigate from a fixed reference point that you mentally sense
导航术：你的精神感觉能将你引导到固定的参考点。 - Geographic axis : man - made arbitrary north - south fixed reference that determines lines of longitude and latitude , and the geographic north and south poles
地理轴：人们制定的北南固定的参考，它们测定经纬线以及地理北极和南极。 - This book is designed to be used on court during practice sessions and matches as a quick fix reference guide for common tennis problems
这一本书被设计使用在练习课和比赛中的球场上,针对常见的网球问题,作为一个很快的修正参考指引, 。 - The idea behind the experiment is simple : put a spinning gyroscope into orbit around the earth , with the spin axis pointed toward some distant star as a fixed reference point
实验背后的原理十分简单：将转动的回转仪放在环绕地球的轨道，转轴指向远处星体，作为固定基准点。 - Kinematic analysis : by denavit - hartenberg method , space geometry relationship of each pole relative to fixed reference frame can be described with equal index transform , also do space relationship of two adjacent poles with 4x4 equal index . so equivalent equal index transform matrix can be deduced from them . when sportive equations and sportive coordinate frame of workpiece exercise point are set up , the coordinate values of exercise point can be got , the pose and situation of two manipulators are analysed , in the end each joint valiable and its velocity , acceleration are worked o ut
运动学分析：利用denavit ? hartenberg法，用齐次变换描述各个杆件相对于固定参考系的空间几何关系，用一4 4的齐次变换矩阵描述机邻两杆的空间关系，从而推导出等价齐次变换矩阵，建立两机械手运动方程，确定工件作业点随动坐标系，求出作业点坐标，对两机械手的位姿进行解析，求出两机械手的各关节变量及其速度、加速度值。
