least-squares fit meaning in Chinese
最小二乘法拟合
Examples
- By least - squares fit of the measured data of speckle correlation function to the obtained quantitative expression , parameters of random surfaces can be extracted
采用最小方差拟合的方法，将散斑相关函数的测量结果与所得到的表达式进行拟合，可以提取出随机表面参量。 - Experimental result , such as excitation potential in frank - hertz experiment , can be quantitatively presented with least - squares fit instead of the average method
通过具有教学普遍意义的“夫兰克赫兹实验”中原子定态能级分析，指出常用的平均法或“类平均法”的局限性。 - The parameters obtained by the least - square fitting deviate from the relations derived from ab formula , abc formula and harris formula , but are closer to relations deduced from ab formula and abc formula
由最小二乘法拟合计算出参数，讨论参数之间的关系，发现他们对ab公式、 abc公式和harris公式的预言存在不同程度的偏离。但相对而言， ab公式、 abc公式的预言较好。 - The least - squares fitting for regular surfaces , such as planes , spheres , cones , tori to 3d data points is researched . the efficiency of computing is improved greatly and the effect of singularities on fitting is avoided
研究了规则曲面的拟合算法，给出最小二乘法拟合平面、球面、圆柱面、圆锥面、圆环面等规则曲面的方法，这些方法的显著优点是提高了计算效率，避免了拟合过程中奇异点的影响。 - 3 j uttler b , felis a . least - squares fitting of algebraic spline surfaces . advances in computational mathematics , 2002 , 17 : 135 - 152 . 4 yang z w , deng j s , chen f l . dynamic implicit curve reconstruction based on approximate geometric distance
其中广义特征向量拟合模型能较好地反映目标形状的拓扑结构，距离函数则近乎完美地刻画了目标的几何信息，因此所得初始隐式曲线曲面能很好地适用于动态重构的迭代过程。
