【摘要】 怎样科学地判断生产系统的稳定性是质量管理的关键问题。研究它不仅具有理论意义，更具有实践意义．本文将系统熵的概念同概率论方面的有关知识以及生产系统处于稳态的五个特征结合起来，推导出了五种熵函数，给出了系统熵和均熵的表达式，从而为判断生产系统的稳定性提供了一种新方法．更多还原

【Abstract】 In this paper, the author has combined the concept of system entropy with five properties of producing system in stable state. At the same time, five kinds of eutropy function and the expressions of system entropyhave beed given. At las, the author has presented a new method for judging stability of producing system.更多还原
