| 1. | The vector product is said to be anticommutative .
可以说矢积是反交换的。
|
| 2. | An axial vector may itself enter into a vector product .
轴矢量自身可参与矢积。
|
| 3. | 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。
|
| 4. | Instead , a custom facing ratio is computed using a vector product utility node in the shading network
相反地，一个特定的分形比率是在材质网络里使用一个积向量功能节点来计算的。
|
| 5. | The vector product node named matrixmult uses a point matrix product operation to multiply those coordinates by the worldinversematrix of the sphere ' s shape node
那是，在球中心的一个点需要去返回一个0 , 0 , 0的数值，不管球在空间的哪个地方。
|
| 6. | The implementation in this paper packs 4 cons 4 * 1 consecutive elements from a matrix column into a texel and thus performs a small number of 4 * 4 matrix by 4 * 1 vector products in a shader
每次从矩阵中取出4个元素放入一个到文理单元的一个元素中， 4 4的小规模矩阵乘法就转变成了4 1的向量乘法。

| 7. | 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。
