摘要： 首先讨论理论模型参数的物理意义，使之与具体软件开发及测试过程建立联系，并以此为依据建立参数的经验估计公式，从而得到参数的先验值。一方面这些参数是软件及软件开发过程的度量值，可用于对软件开发过程的控制、优化和管理；另一方面，有了先验值后，就可对理论模型进行经验贝叶斯扩展，以使人们的软件实践经验融入到理论模型中。

Abstract: The empirical estimation of the parameters is addressed. On one hand, these empirical estimates are also measurements of the software, which can be used to control and to optimize the process of software development. On the other hand, by taking these empirical estimates as Bayes priors, software reliability models are extended so that engineers' experience can be integrated into models and hence to improve the models.
