一引言在生产过程中,经常遇到两个与时间t成函数关系的变量(x,y)的乘积。人们通常把时间的积分值W作为计算或控制生产过程的依据,但变量x或y不一定是事先的给定值,而往往是在生产过程中随机发生。动态近似积分计算机(简称近似积分机)就是根据变量动态过程的特点、利用舍尾求整的方法来进行设计的。它能进行运算的数学形式为: I. INTRODUCTION In the production process, the product of two variables (x, y) that are functionally related to time t is often encountered. Generally, the integral value of time W is used as the basis for calculating or controlling the production process. However, the variable x or y is not necessarily a given value in advance and is often randomly generated in the production process. Dynamic approximate integral computer (referred to as approximate integrator) is based on the characteristics of the dynamic process of variables, the use of the method of tail trimming to carry out the design. The mathematical form it can do is:
