approximation value meaning in Chinese

近似值

Application of approximation value to revise diagnosis matrix in fuzzy diagnosis process
贴近度对模糊诊断矩阵的实时修正应用研究
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
最后针对现有算法对带有方向的纹理合成效果差，无法直接合成纹理图像的难点，本论文首先提出了非正平行纹理与正平行纹理的概念，分析了它们之间的内在联系，引入了两个角度参数来描述纹理的朝向，采用傅立叶频谱法分析纹理的方向特性，并提出了纹理主方向的概念，本论文引入离散逼近的方法来求解出纹理主方向的近似值，这样我们就能用一种间接的方法合成简单的结构性非正平行纹理。
