查询词典 tracing

Its most advantage is: it is suitable for any complex geology structure, the"iterative"ray tracing method is based on Fermat"minimum travel time principle", it uses Taylor expansion and finds the solution segmentally and iteratively, then modifies the initial ray path.

迭代射线追踪方法是根据Fermat最小旅行时原理，应用Taylor展开，分段迭代求解，再逐次修改初始射线路径，完成全射线路径的迭代求解过程，其最大优点是计算的速度快，追踪射线效率高。

Furthermore, this model is expanded in two aspects: on the one hand, through the introduction of the theory of the Fault Tree, this thesis analyzes the difference between the fault-diagnosis in the recovering flow and that in the traditional flow, thus concluding that the fault-diagnosis in the recovering flow is just a tracing-back process of the directed-graph and the Fault Tree; on the other hand, a finite self-restoring state machine is constructed on the directed-graph model, thus providing the theoretical basis for the realization of the auto-recovery model.

随后在两个方面对该模型进行了扩展：1。通过引入故障树的方法，并在分析了恢复流程故障诊断与传统故障诊断的差异之后，总结出恢复流程的故障诊断就是一个基于有向图和故障树进行回溯的过程；2。基于有向图模型建立了一个有穷自动状态机，为自动恢复与模型的实现提供了理论基础。
