approximate approach meaning in Chinese
近似法
Examples
- Study on data approximate approach of spiral surface profile
螺旋曲面廓型的数值拟合方法研究 - ( 2 ) the theory basis and realization methods of the computer simulation approximate approach are discussed in this paper
( 2 )研究了计算机模拟逼近法的理论依据和实施的技术方法。 - 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
计算机模拟逼近法既能以图的形式展示机构位置、速度加速度的方位变化，又能得到与解析法非常相近的求解精度，又不需推导繁琐的解析公式。 - 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。 - Using the method of parabolic regularization , we first study the existence of the optimal control of nondegenerate systems governed by where and jn is mollifying sequence in r . by de giorgi - nash ' s technique , we obtain some uniformly estimates of solutions of regularizing prob - lem , from compactness , we prove the existence of the optimal control of degenerate system by a approximate approach
利用抛物正则化方法，我们首先研究了非退化系统最优控制的存在性，其中而j _ n是r上的软化子。利用degiorgi - nash技巧，对正则化问题的解可以得到一些一致估计，利用紧性，通过一个逼近过程我们得到了退化系统最优控制的存在性。
