Firstly the paper digitalizes relief map and analysis the "non-source flood" and "source flood",then using self function of ArcMap or ArcView to calculate flood submerged area of source flood and non-source flood area respectively;next,for proving means feasible,the paper takes 2003 flood data of lower reaches of Weihe River as example to contrast or validate.

因此，快速、准确、科学地模拟预测洪水淹没范围以及计算洪水淹没面积，对防洪减灾具有重要意义。20世纪90年代以来，特别是近几年来，在水动力-水文模型基础上，利用GIS强有力的空间分析和可视化功能，模拟显示洪水淹没区，一直是一个研究热点。

Through scheduling process analysis of periodic task, the waiting limit formula of each task in ready queue was obtained while guarantees its deadline. In addition, some properties, such as final preempting time was deduced and the necessary condition of periodic tasks preempting behavior was described quantitatively. Based on them, a micro scheduling preemption model for periodic tasks in ready queue was put forward, which decreased the number of preemptions and optimized system performance through changing the preempting sequences.

通过分析周期性任务的调度过程，得出在确保任务不错过截止期条件下，各个任务在就绪队列中可等待的最长期限计算公式，并根据公式推导出任务满足截止期的最后抢占时刻等属性，从而定量地刻画了周期性任务抢占行为发生的必要条件，提出了一套对周期性任务的就绪队列进行微调度的抢占模型，通过改变抢占关系来减少抢占次数、优化实时系统性能。

In chapter eight, the new software system named"simulation and protection scheme analysis of synchronous generator with internal armature winding faults", is developed and introduced. This software can be broadly applied to the analysis and protection study of synchronous generator with internal armature winding faults.
