A method with quadratic curve precision for determining knots 二次曲線精度的節(jié)點(diǎn)計(jì)算方法
Quadratic curve in higher geometry 高觀點(diǎn)下的二次曲線
However , the quadratic curve is only c ? continuous , while the cubic ' s is c1 continuous 還給出球面上等距節(jié)點(diǎn)二次和三次b樣條曲線的插值方法。
There was a quadratic curve relation between unit cost and yield . the unit cost was the lowest when the yield was about 400 kg / mu 且小麥生產(chǎn)的單位成本與產(chǎn)量之間呈極顯著二次曲線關(guān)系,產(chǎn)量為400kg /畝左右時(shí),單位成本最低。
The paper expounds the algorithms of generating quadratic curve . using quadratic curve and cubic bezier curve enforces the smooth of curves 論文闡述了幾種二次曲線生成算法;說明如何應(yīng)用二次曲線和三次bezier曲線擬合改善曲線的光滑性。
Polynomial , transcendental function , new quadratic curve , b - spline and nurbs have been used in expression of hull molded line , trapezoidal method , simpson method have been used in static calculation 在船體型線的表達(dá)方面有多項(xiàng)式、超越函數(shù)、新二次曲線、 b樣條函數(shù)、非均勻有理b樣條函數(shù)等。
7 . a high - speed photography software system was designed , and was used in the straw throwing experiment . the results show that the trace is similar to the quadratic curve predicted by theory 7設(shè)計(jì)了由圖像預(yù)處理模塊、運(yùn)動(dòng)目標(biāo)提取模塊、運(yùn)動(dòng)目標(biāo)跟蹤模塊以及跟蹤結(jié)果數(shù)據(jù)保存模塊組成的土槽高速攝像軟件系統(tǒng),并將系統(tǒng)應(yīng)用到秸稈拋撒試驗(yàn)的軌跡研究中。
4 . the results indicated that the applied nitrogen amount had a quadratic curve relation with grain yield . yield and profit increased with the amount of nitrogen applied under a certain amount of nitrogen 田間試驗(yàn)結(jié)果表明,施氮量與產(chǎn)量呈二次曲線關(guān)系,在一定的施氮量范圍內(nèi),產(chǎn)量和經(jīng)濟(jì)效益都隨施氮量增加而提高,超過施氮量閾值,增加施氮量,產(chǎn)量和經(jīng)濟(jì)效益下降。
In order to verify the feasibility of ann , adopting same training sample the author establishes quadratic curve model and index model of tourism foreign exchange income and cubic curve model and index model of total inbound tourist quantity 為了驗(yàn)證人工神經(jīng)網(wǎng)絡(luò)模型的可行性,筆者用同樣的訓(xùn)練樣本分別建立了旅游外匯收入二次曲線模型、指數(shù)曲線模型和入境游客三次曲線模型、指數(shù)曲線模型。
