上曲线 meaning in Chinese
u er curve
upper curve
Examples
- The interpolation , approximation and other things for curves on smooth surfaces with computer are studied
本文研究光滑曲面上曲线的计算机表示、插值与逼近等。 - Is put forward , followed by the construction of nurbs curves on quadratic surfaces , and the interpolating curve restricted on general surfaces
进一步给出了用nurbs表示的任意曲面上nurbs曲线构造，揭示了曲面上曲线的连续性。 - Following that , when the image set is . , based on constructing the mapping : g : d , the origin problem is transformed into the general interpolation curve construction on ft2 . thus a efficient method in the construction of a curve restricted on smooth surfaces
通过建立映射g ： dcw ‘一w ’ ，使像集即为曲面二，将曲面z上的曲线构造转化为通常w ‘上曲线构造，提出了一种二维流形上曲线构造的有效方法。 - In this paper we analyze the revolver of the curve revolving around the straight line , discuss the calculations of the area and volume of the revolver , get two integral formulas of the calculations of the area and volume , and illustrate the application of the formulas with examples
摘要针对数学分析中平面上曲线绕平面上任意直线旋转一周而形成的旋转体进行分析研究，运用微元分析法，对旋转体体积及旋转体与过该直线的截平面相交所得面积进行讨论，得到相应的积分公式，并举例说明公式的应用。 - This report is composed of two main parts , one concerns some geometric inequalities about curves and an application of the minkowski ' s support function , the other deals with the perimeter - preserving flow of closed convex curves in the plane and an application of the curve shortening flow on surfaces
本文主要由两个部分组成，第一部分涉及曲线的一些不等式以及minkowski支撑函数的一个应用；第二部分讨论欧氏平面上闭凸曲线的保长度流和曲面上曲线缩短流的一个应用。
