一、导言 动态数据系统(Dynamic Data System,简称DDS)是一种建立数学模型的方法,它是采用一种时间序列形式的动态数据来建立一个具有物理意义的随机差分和(或)微分方程。DDS法的初始工作约始于10年以前(六十年代中期),其中还包括了对一个砂轮外形特征的定量描述。尽管砂轮
I. INTRODUCTION The Dynamic Data System (DDS) is a method of establishing a mathematical model. It uses a dynamic time-series data to create a physically meaningful stochastic difference and / or differential equation. The initial work of the DDS method began about 10 years ago (mid-1960s) and included a quantitative description of the profile of a grinding wheel. Despite the wheel
