模型检测时，实时系统的大多数安全属性和部分活性都可以通过可达性分析算法来验证。

For most safety properties and some liveness properties of real-time systems, model checking can be reduced to reachability analysis.

组合可达性分析是对并发系统模型分析验证的基础和关键，但是难于解决验证中的所谓的状态爆炸问题。

Model checking and refinement checking are two approaches to formal verification, whose difficulties are due to the state explosion problem.
