English translation for "open curve"

开曲线

Example Sentences:

	1.	Experiments shows it is an effective approach to recognizing open curves 实验表明这种方法能够有效地解决开曲线的形状识别问题。
	2.	Aim at lacking a kind of method for drawing intersecting lines efficiently in the petrochemical engineering construction , invented a kind of compasses that can draw the opening curve on the non - flat container wall 摘要针对石油化工设备建造中，缺乏一种高效的器壁开孔画曲线方法的问题，研制了一种能在非平面器壁上画开孔曲线的画线规。
	3.	At last , a better idea is presented : in fact , the problem of computing the shape distance between two open curves can be changed to the problem of a functional extremum , therefore , we can get the shape distance through solving an euler equation 本文在最后还证明了这样一个结论，两条平面开曲线的形状距离的计算问题可以转化为一个泛函的极值问题，于是通过解一个欧拉方程就可以求出两条开曲线的形状距离。
	4.	In this paper , we study the numerical solutions of these problems using galerkin boundary element , especially for the problem with open boundary such as the problems exterior to an open segment or an open curve in the plane . since the equivalent boundary integral equation for two dimensional laplace equation has constraint condition 因为把二维调和方程的边值问题转化为等价的边界积分方程时带有约束条件，用galerkin边界元方法求解带约束条件的变分方程，在数值离散时，我们采用lagrange乘子法处理约束条件。
	5.	A curve is regarded as the trace of a moving body , the force acting on which decides the shape of the curve . through some necessary shape transformation , the shape distance or shape difference between two open curves can be valued by comparing their mechanical causation . therefore , the purpose of recognizing open curves is reached 曲线可以看成是物体运动的轨迹，那么物体在运动过程中所受到的力就决定了曲线的形状，将两条曲线适当地变形之后，通过比较各自的形状形成的力学原因，就可以计算出它们的形状差异或形状距离，从而达到曲线形状识别的目的。
