  • fit : vt （ tt ）1 適合。2 使適合，使適應使（服裝等）合身使合格，使勝任〈美國〉使準備（投考）。3 為…提...
  1. This process is as follows : firstly, the data of different section contour and of section line have been obtained by reverse - engineering ; secondly, non - uniform b - spline approximation algorithm is used to fit the discrete data ; then the data have been optimized and reduced by adopting adaptive sampling of key points of the fitted curve based on vertical distance, sequently the adaptive sampling data is transformed into the format of the. ibl file of the famous 3 - d design software pro / e. therefore we reconstruct the surface and a model is generated ; lastly, the effectiveness of the adopted algorithm and modeling approach are demonstrated by the experiments

    建模型的過程中，首先運用逆向工程測量方法，獲得曲面物體上不同截面輪廓線的測量數據點列，接著對測量數據點進行平滑處理，用最小二乘法求解基於數據點列的控制多邊形，以非均勻三次b樣條曲線擬合截面輪廓曲線；然後利用基於垂距的數據采樣演算法，對擬合曲線上的數據點進行重新采樣，達到優化數據點的分佈及減少描述曲線數據量的目的。
  2. It offers the idea according to problem faced, considering the good character of the ends, the ajusted cubic b - spline curve is used to fit ship lines. it finds out the control vertexs according to a sequence of given points, and then, through particular formula, each point in the curve could be worked out. it smoothes lines with the method based on small - paramter

    針對面臨的問題，提出了自己的思路，在數學計算方法上，由於三次準均勻b樣條曲線良好的端部性質，這里用它來擬合船舶型線，首先根據所給的初步型值求出其控制頂點，然後根據相關公式進行插值便能得到曲線上的所有插值點。
  3. According to the relation between gear wear and its vibration, continuous wavelet transform is introduced to estimate the wear condition, the energy values of continuous wavelet on scale fit a spline which is much like that of the wear course of the gear

    最後，將基於連續小波變換的信號處理方法引入變速箱齒輪的磨損估計。根據信號的連續小波變換的能量譜對尺度的積分值，擬合得到齒輪的磨損過程曲線。
  4. As the basic concept, the first step is to modeling by ug. there is different model between propeller and commonly hardware, so we must be use curve modeling, at the same time, characteristic modeling and entity modeling in the whole process. first, we apply offset data for spline fit curve, then scanner smooth curve face

    首先在三維繪圖軟體ug中對螺旋槳及葉片進行三維建模，由於螺旋槳的造型不同於一般零件的cad造型，故在造型過程中同時採用了曲面造型，特徵造型和實體造型幾種方法，先由型值數據生成樣條曲線，再由樣條曲線掃掠生成平滑的曲面，最後通過圓整?延伸得到螺旋槳的三維模型。
  5. The experiment shows that its results are close to ones of cubic - spline function, and fit to the criterion of jtj011 - 94 requirement

    公路平面線形實例設計表明，三次埃爾米特插值函數用於公路平面線形設計中，能夠滿足路線設計規范（ jtj011 - 94 ）的要求，其設計結果與三次樣條函數設計結果接近。
