中文摘要：

为有效地保证Web服务业务活动中事务可靠地执行，提出了一种检查伙伴服务之间协调行为一致性的方法。针对长事务给出用Pi-演算建模业务活动中服务协调行为的方法；定义了标号迁移系统和Kripke结构这两种状态自动机之间的语法映射关系，提出了PI-演算进程模型到符号模型检测工具输入语言的转换方法；在模型检测结果的基础上，用反例引导用户进一步精化模型，以解决业务流程集成中参与者协调一致性问题。通过实例验证了该方法的有效性。

英文摘要：

To ensure the reliability of transaction execution in Web service business transaction, an approach to check the consistency of coordination actions among partner services was proposed. Aiming at the long-running transac- tions, a rigorous method by using Pi-calculus to calculate the service activities coordination in modeling business was put forward. The syntax mapping of automaton between Labeled Transition System（LTS）and Kripke structure was defined, and transformation from Pi-calculus process model to imput language of symbolic model checking was pro- posed. On the basis of test result, a counter-example was used to refine the model. Therefore the coordination prob- lem of participants in business process integration was solved. The example was used to verity the effectiveness of proposed method.
