食品包装配重中的一类数学问题

A Class of Mathematical Problems in the Food Packaging Counterweight

配重是食品包装中的一个不可缺少的环节。目前,生产实际当中亟待解决的问题是如何提高配重的效率和质量精度,而配重首先要解决的问题是随机变量自身条件分布的问题。本文运用随机数学的方法,给出了离散型随机变量的条件分布律和连续型随机变量的条件概率密度,从而解决了食品包装中的相应问题。

The counterweight is an indispensable link in the food packaging.At present,the urgent problem in the actual production is how to increase efficiency in the course of counterbalance and improve the accuracy of the quality.The problem in the counterweight that should be first solved is the question of a random variable itself conditional distribution.This paper not only gives the conditional distribution law of the discrete random variables,but also obtains the conditional probability density of the continuous random variables by using random mathematical method.Then the corresponding problems in the food packaging can be solved.
