原始曲线 meaning in Chinese
primary curve
virgin curve
Examples
- Really , all you have to be able to do is manipulate the points that make up the original line , which will be drawn iteratively
实际上，必须要做的全部工作就是操纵构成原始曲线的点，原始曲线会迭代地绘制出来。 - Using " identity " idea and anomaly criterion of slave function , remain curve and original curve deviation etc , a set of medium - term , short - term and imminent term anomaly of the moderately strong earthquakes , especially those with intensity v above magnitude 5 earthquakes are extracted
运用“同一化”思路、从属函数、剩余曲线及原始曲线均方差等异常判定方法，提取了中等以上地震，特别是5级以上地震的中、短、临异常实例。 - Reverse engineering , based on measured data , is a technology trying to reconstruct curves and surfaces in consistent with the measured objects in a requested precision for the practice engineering . the measured data is partly information of original curves and surfaces so that there is always some uncertainty and unknown information . the interpolation and approximation methods should be used to find these unknowns when reconstructing them
基于测量数据的逆向工程模型重构技术,其测量数据是原始曲线、曲面中的部分信息,基于测量数据直接构造模型还存在一些不确定因素,因此需通过插值、拟合来挖掘原始曲线曲面的特征,通过离散的点来构建连续的曲线和曲面,从而获得满足工程要求且与被测量物体一致的cad模型。 - The methodology adopted by most existing cam / cnc systems , which uses huge amount of linear segments to approach the original shape and make linear interposition increases the cost of memory size and communication work of the cnc system tremendously . a new approach based on cubic polynomial and b spline interposition to rebuild the cam generated tool path under real time condition is presented in the paper . applications on cnc machine tools showed that the presented approach improves the machining accuracy and increases the cutting speed significantly
目前大多数cam / cnc系统采用大量小直线段逼近原始曲线和直线插补的做法，只能获得零阶连续的走刀轨迹，逼近精度低，不能保证高速加工运动的平稳性，因而加工精度、光洁度和加工速度都难以提高；由小直线段构成的nc代码数据量庞大，也增加了数控系统在内存容量和数据传输方面的成本。 - The solution regards the original given interface ( original curve or interface ) as one zero set of function , transferring the some phenomena such as topology to lever set function in higher dimension , and getting moving interface of original interface at different time through resolving the level set function
水平集方法是把最初给定的截面(原始曲线或面)看作是某个函数零集，把求解等距过程中发生的拓扑等现象转移到高一维的水平集函数中去，通过求解该水平集函数以得到原始截面不同时刻的等距面。
