Based on this requirement, this paper introduced steerable filters: generated a pair of even and odd filtered images by convoluting a quadrature pair of steerable filters with a source image, and then through continuously varying their phases over time, it gave the vision of an object in motion without changing its position. created the animation conveniently in this way.
基于这种需求,将定向滤波引入到非真实感动画中:利用一对正交的定向滤波核与源图像进行卷积运算,产生一对奇偶滤波图像,并通过不断改变其相位得到一系列运动的图像,使图像内的物体在实际位置并不发生改变的情况下,产生视觉上的动画效果,从而方便地生成非真实感动画。

Ostwald ripening is a key mechanism in the destabilization of emulsions (for example, by creaming and sedimentation).
同时最近几年,Banfiled又提出了一种新的晶体生长机制也能形成单晶结构,oriented attachment,多个取向不一致的单晶纳米颗,通过粒子的旋转,使得晶格取向一致,向后通过定向附着生长使这些小单晶生长成为一个大单晶,当然定向附着的过程出难免会出现一些位错和缺陷,这种生长机理形成的单晶的特点同Ostwald ripening不同,OR形成的单晶大多是规则的,给材料本身晶体结构相关,而OA形成的单晶结构在形貌上则没有限制,任何形状和结构的单晶材料都能通过此机理形成。

Firstly, this thesis makes an introduces on the developement of PMSM servo system based on DSP. According to the control theory of AC PMSM servo system, this paper analyzes the coordinate transformation, the rotor magnetic field orientation and the current control strategy of AC servo system. The control strategy is i_d=0. The system is orientates towards rotor magnetic field. Then the mathmatic models of PMSM in d-q coordinate are set up.

The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.
脱颗中的组胺等物质会引起毛细血管壁通透性的增加,进而引起组织液流动速度的增加和肥大细胞表面的切应力加大,这样会进一步促进肥大细胞的激活,从而释放更多的活性物质,这些物质一部分被静脉端毛细血管吸收进入血液,另一部分则随着组织液的定向流动向远处,并进一步刺激远处的毛细血管和肥大细胞,而组织液的定向流动途径和传统的经络线走向基本吻合,在宏观上就构成了循经感传现象。
