composite vector
解釋
合成矢量-
While two ( or more ) electromagnetic waves of the same frequency, same direction of vibration, same phase or constant phase difference superpose in space, the amplitude of composite wave is vector sum of the amplitude of each wave
由兩個（或兩個以上）頻率、振動方向相同、相位相同或相位差恆定的電磁波在空間疊加時，合成波振幅為各個波的振幅的矢量和。 -
In order to improve dynamic performance of the control system in the assembly robot, according to acpmsm ( ac permanent magnet synchronous motor ) vector control model and the control idea about preview control, the paper presents a kind of control strategies that is composite of a primary pid ( proportion integral dif - ferenfial ) with a preview feed - forward compensation, its compensation is equivalent to linear combination of future adjacent difference, the simulation results show that it can not only improve the system tracking performance effectively, but also implement easily
摘要為了提高裝配機器人控制系統的動態性能，依據交流永磁同步電機矢量控制模型，從預見控制的思想出發，提出了一種在原有pid基礎上外加預見前饋補償的控制方法，這種控制方法的前饋補償項取未來幾項目標值一階差值的線形組合，並模擬驗證了該控制方法對提高系統跟蹤性能的有效性和簡單可行性。 -
Finally enzyme is covalently immobilized. the reclaimed efficiency of immobilized enzyme that is prepared by this vector is over 76 %, but others are between 45 % and 65 %. it shows that activated magnetic polymer composite microspheres is an efficient vector that can be applied immobilization field
通過這類載體制備的固定化酶的酶活回收率在76以上，而由一般載體制備的固定化酶的酶活回收率在45 - 65之間，這表明活化后的磁性高分子復合微球是一類可以應用於酶固定化領域的高效載體。 -
A composite rotor flux observer is applied to induction motor vector control system, which makes the system avoid to be influenced by the alteration of rotor resistance
摘要採用基於電壓模型及電流模型的復合磁鏈觀測器，避免了矢量控制時異步電機工作溫升引起的轉子電阻變化所帶來的磁鏈觀測不準確問題。 -
A new system of nonlinear equations can be formed from the variation gray of same point in multiple images and the optimum solution of the system can be obtained, so that the normal vector at that point of the surface can be defined. then we can get the surface height at the point by applying composite numerical integration. according to variational calculus and finite difference method, the fitted surface is further iterated and modified, so the reconstruction error can be reduced
根據多幅圖像上固定位置一點灰度值的變化列多個非線性方程，通過求解該非線性方程組，確定出各選取點的法向量；然後通過復化積分確定選取點的高度值，並利用變分和有限差分思想對所得表面進行進一步的迭代和修正，以減小重構誤差。
