lastly, using the compactly supported radial functional to take the place of the polynomial function, local radial point interpolation method, is presented in this paper 最后,本文采用緊支距離基函數(shù)取代多項(xiàng)式基函數(shù),提出了局部徑向點(diǎn)插值方法,這是一種真正意義上的無網(wǎng)格方法。
(6 ) the number of fuzzy rules could directly be calculated and does not need be testified by using the formula proposed in the paper for multivariable polynomial function (6)對多變量多項(xiàng)式函數(shù)情形,本文給出的模糊規(guī)則條數(shù)的計算公式,不再需要進(jìn)行檢驗(yàn),可以直接用于計算所需模糊規(guī)則條數(shù)。
pythagorean hodographs exhibit remarkably attractive properties for practical use . for example, their arc length is expressive as a polynomial function of the parameter, and their offsets are rational curves ph曲線呈現(xiàn)出非常優(yōu)良的實(shí)際應(yīng)用價值,例如它的弧長可表示為曲線參數(shù)的一個多項(xiàng)式函數(shù),其等距線是有理的。
a polynomial function of 3-sat to area minimization was given in a pubilshed thesis, this could prove the area minimization is a np-complete problem . but this must be discussed in there cases : k 5, k = 4, and k = 3 原有的證明是利用3-sat問題規(guī)約到面積優(yōu)化問題,但是要分別對k5、k=4和k=3的情況分別討論,證明過程比較復(fù)雜。
and compared to the vertical wetting front, the rate of horizontal wetting front was 1.22 times higher . different models were used to fit the movement of wetting front, it is found that the polynomial function was a good model 粘質(zhì)(土婁)土,由于質(zhì)地細(xì)小,在滴灌速率為2.67lh時,濕潤鋒徑向移動速率遠(yuǎn)大于垂向移動速率,前者是后者的1.22倍。
