product n. 1.產(chǎn)物,產(chǎn)品;制品;產(chǎn)量;出產(chǎn)。 2.結果,成果。 3.創(chuàng)作,作品。 4.【化學】生成物;【數(shù)學】積,乘積。 natural products 天然產(chǎn)物。 agricultural products 農(nóng)產(chǎn)品。 residual product 副產(chǎn)物。 40 is the product of 5 and 8. 40是5和8的積。
The vector product is said to be anticommutative . 可以說矢積是反交換的。
An axial vector may itself enter into a vector product . 軸矢量自身可參與矢積。
Vector products arise frequently in this book in a number of contexts . 在本書的許多場合中經(jīng)常要出現(xiàn)矢量積。
Instead , a custom facing ratio is computed using a vector product utility node in the shading network 相反地,一個特定的分形比率是在材質(zhì)網(wǎng)絡里使用一個積向量功能節(jié)點來計算的。
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,在球中心的一個點需要去返回一個0 , 0 , 0的數(shù)值,不管球在空間的哪個地方。
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 每次從矩陣中取出4個元素放入一個到文理單元的一個元素中, 4 4的小規(guī)模矩陣乘法就轉變成了4 1的向量乘法。
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,作者針對機器人的設計要求提出了多個方案,對其進行分析比較,選擇其中最優(yōu)的方案進行了結構設計;同時進行了運動學分析,用d - h方法建立了坐標變換矩陣,推算了運動方程的正、逆解;用矢量積法推導了速度雅可比矩陣,并計算了包括腕點在內(nèi)的一些點的位移和速度;然后借助坐標變換矩陣進行工作空間分析,作出了實際工作空間的軸剖面。
