矢量积 meaning in Chinese

cross product
outer product
vector product

Vector products arise frequently in this book in a number of contexts .
在本书的许多场合中经常要出现矢量积。
The best scheme was chosen after analysis and comparing and the structure was designed . at same time , the kinematics analysis was conducted , coordinate transformation matrix using d - h method was set up , and the kinematics equation direct solution and inverse solution was deduced , the velocity jacobian matrix was constructed using vector product method , and the values of displacement and velocity of some special point including the wrist point were calculated . secondly , the working space of the robot was analyzed and the axes section of practical working space was drawn
首先，作者针对机器人的设计要求提出了多个方案，对其进行分析比较，选择其中最优的方案进行了结构设计；同时进行了运动学分析，用d - h方法建立了坐标变换矩阵，推算了运动方程的正、逆解；用矢量积法推导了速度雅可比矩阵，并计算了包括腕点在内的一些点的位移和速度；然后借助坐标变换矩阵进行工作空间分析，作出了实际工作空间的轴剖面。
