3. However , the computer simulation approximate approach not only clearly indicates the changes of mechanism position , velocity and acceleration orientation by means of figures , but also obtains the closely same accuracy of the analytics without the boring calculation
   計(jì)算機(jī)模擬逼近法既能以圖的形式展示機(jī)構(gòu)位置、速度加速度的方位變化，又能得到與解析法非常相近的求解精度，又不需推導(dǎo)繁瑣的解析公式。
4. Lastly , aiming at the poor results which all current algorithms do for directional textures , and cannot synthesis texture directly , aiming at the particularity of this kind of textures , we bring forward the conceptions of non frontal parallel textures and frontal parallel textures . by analyzing texture ' s direction through fourier spectrum , we introduce the conception of main direction , and solve the approximation value of texture ' s main direction by discrete approximated approach . by this way , we can synthesis indirectly simple structural non frontal parallel textures
   最后針對(duì)現(xiàn)有算法對(duì)帶有方向的紋理合成效果差，無(wú)法直接合成紋理圖像的難點(diǎn)，本論文首先提出了非正平行紋理與正平行紋理的概念，分析了它們之間的內(nèi)在聯(lián)系，引入了兩個(gè)角度參數(shù)來(lái)描述紋理的朝向，采用傅立葉頻譜法分析紋理的方向特性，并提出了紋理主方向的概念，本論文引入離散逼近的方法來(lái)求解出紋理主方向的近似值，這樣我們就能用一種間接的方法合成簡(jiǎn)單的結(jié)構(gòu)性非正平行紋理。
