spline fit curve meaning in Chinese

试配曲线
样条拟合曲线

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
首先在三维绘图软件ug中对螺旋桨及叶片进行三维建模,由于螺旋桨的造型不同于一般零件的cad造型,故在造型过程中同时采用了曲面造型,特征造型和实体造型几种方法,先由型值数据生成样条曲线,再由样条曲线扫掠生成平滑的曲面,最后通过圆整?延伸得到螺旋桨的三维模型。
