- By least - squares fit of the measured data of speckle correlation function to the obtained quantitative expression , parameters of random surfaces can be extracted
采用最小方差擬合的方法，將散斑相關函數(shù)的測量結(jié)果與所得到的表達式進行擬合，可以提取出隨機表面參量。 - Experimental result , such as excitation potential in frank - hertz experiment , can be quantitatively presented with least - squares fit instead of the average method
通過具有教學普遍意義的“夫蘭克赫茲實驗”中原子定態(tài)能級分析，指出常用的平均法或“類平均法”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
由最小二乘法擬合計算出參數(shù)，討論參數(shù)之間的關系，發(fā)現(xiàn)他們對ab公式、 abc公式和harris公式的預言存在不同程度的偏離。但相對而言， ab公式、 abc公式的預言較好。 - 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
研究了規(guī)則曲面的擬合算法，給出最小二乘法擬合平面、球面、圓柱面、圓錐面、圓環(huán)面等規(guī)則曲面的方法，這些方法的顯著優(yōu)點是提高了計算效率，避免了擬合過程中奇異點的影響。 - 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
其中廣義特征向量擬合模型能較好地反映目標形狀的拓撲結(jié)構(gòu)，距離函數(shù)則近乎完美地刻畫了目標的幾何信息，因此所得初始隱式曲線曲面能很好地適用于動態(tài)重構(gòu)的迭代過程。
