In reverse engineering, the character of surface border curve in complex contoured product is the key factor affecting the outlook designing quality of product. 在逆向工程中,复杂外形产品的曲面边界曲线的品质,是影响产品外观设计质量的关键因素。
In order to realize the higher precision of image measurement, this paper deeply studied the typical sub-pixel location arithmetic at border of image, presented sub-pixel location arithmetic based on Gauss Curve fitting and interpolation in the gradient direction. The decision came to sub-pixel level. 为了进一步实现更高精度的图像测量,还深入地研究了典型的亚像素定位算法,提出了在梯度方向上进行高斯曲线拟合插值的亚像素边缘定位算法,使测量精度达到亚像素级。
: We discuss the damage border ourve of product fragility and the absorption curve of absoption material in the paper. And they are used in the design dimension of absortion material. 运用产品易碎性损坏边界曲线及缓冲材料的缓冲曲线推导出缓冲材料的设计尺寸及在设计中的应用。
On the basis of this, the initial boundary curve is faired by use of B-spline fitting technology and the offset curve of the initial border curve is constructed. 然后又通过B样条曲线拟合技术对初始边界曲线进行了光顺,并求出光顺后边界线的切矢及法线方向,进而构造出边界曲线的等距线。

Border disease: a review damaged bounds of products packaging with cubical nonlinearity by 3-D curve surface 立方非线性产品包装损坏边界的三维曲面表示
-Economical recoverable reserves refer to the petroleum and natural gas cumulative production with economic value from underground in the border of the profit and loss curve. 经济可采储量是指在一定技术经济条件下,在盈亏边界值内从地下采出的有经济价值的原油和天然气液的累积(年)产量。
The collision rule and border is designed. The results of the curve of the temperature response in thermoacoustic engines, which is logical, shows the assumption is feasible. 2. 设计了相应的碰撞规则、边界处理方法,模拟所得的热声发动机的温度响应曲线结果合理,表明了模拟的假设可行。
