In ovder to monitor and improve the electronic environment in the examination places of the english listening entrance examination , this paper suggests some practical appvoaches and measures which are based on the problems we found through monitoring several examination places in jiujiang during the english listening entrance examination in recent years 摘要本文根据近年来在江西省九江市高考外语听力一些考点进行电子环境的检测工作中发现的问题，提出对考点电子环境检测与改善的建议、措施和方法，以期待我们的检测与改善工作在研究交流中得到发展，在实践工作中得到提高。
As a practical application , the safety situation of jiujiang dike under the 1998 pluvial condition of once a hundred years in yangtze river has been evaluated by the reliability method from the point view of the seepage stability in terms of probability analysis and two dimensional saturated seepage finite element analysis combining with the mechanism of seepage burst in jiujiang dike summarized in the thesis 通过渗流有限元和渗流可靠性分析论证了1998长江流域特大洪水灾害中九江市防护大堤发生的严重溃口破坏的渗流破坏机理。分析、比较得出结论：堤防下游坡脚的出逸比降接近和超过临界比降，在1998年长江百年一遇的洪水条件下九江大堤溃口断面的抗渗可靠性仅在55左右的非常低水平。
