中文摘要：

对“危险”的定义是将危险理论用于人工免疫系统所需要解决的核心问题.云模型是一种定性与定量之间相互转换的有效工具.论文借鉴云模型的概念对计算机系统中系统变量的变化进行判定,从而给出危险信号的定义;综合多种危险信号,进而给出“危险”的定义.最后,提出了利用“危险”和nonself的识别共同激发免疫响应的协同识别模型框架.

英文摘要：

The definition of danger is one of the most important problems need to be solved in the application of Danger Theory in AIS.Cloud model is an effective tool in transforming between qualitative concepts and their quantitative expressions.This paper uses the concept or Cloud model to estimate systematic parameters and consequently presents the definition of danger signal.Integrate various danger signals the definition of danger is got.At last,a coordinated stimulate model including both self-nonself recognition method and danger recognition method is presented.
