摘要： 在具有多个应用协作以及长周期事务的复杂信息环境中，针对短事务设计的事务性工作流表现出一定的局限性。在分析了现有长事务处理方法的不足后，基于事务对象层次网络的定义，该文提出了一种长事务处理的最小原子汇集法，介绍了最小原子事务汇集策略及最小原子范围的确定过程，以一个注塑模具产品开发过程的案例验证了该方法的有效性。

Abstract: The traditional transactional workflow is conditioned by complex information environment (collaboration of various applications, long lived transaction), because it is designed for short transaction. This paper analyses the shortcoming of known methods to solve LLT problems, and presents the minimum atom range aggregation method based on the layered network of transactional object, it also describes the detailed computation of smallest atomic scope. An injection mold product development process is presented as an example of the method to prove its validity.
