例如石松屬和卷柏屬,植物體上具有雙行較大的側生葉,還有1行或2行較小的生於近軸面或遠軸面的葉。An optimizing arithmetic for calculating the best - fit sphere is also proposed, the result shows better accuracy is reached comparing to " three points method ", from 107. 8umrms to 25. 66umrms. during interferometric optics test with null lens, " nonlinear errors " of the testing coordinates will be introduced. a method based on ray - tracing, nonlinear fitting and coordinate transferring is proposed to eliminate these errors
在ccos控制模型及理論計算方面,提出了一種適用於高次離軸非球面最接近球面計算的優化演算法,經計算,某矩形離軸非球面最接近球面半徑的求解精度較傳統的「三點法」有了較大的提高,理論加工余量由原來的107 . 8umrms降低到25 . 66umrms ;提出一種基於磨頭與工件的相對位移量的控制模型,並且開發了阻尼卷積迭代演算法,引入「虛擬加工」的概念進行迭代求解和參數評價。
