基于CXF的信息汇集通用系统设计与实现

为将大坝监测信息从分散在各地的监测数据库汇集至中心数据库,采用CXF框架,设计并实现了信息汇集通用系统。通过简单配置,即可将监测信息汇集至中心数据库,方便水库主管部门对监测信息进行处理、分析,以保障大坝安全运行。     

大坝安全监测仿真实验控制系统的研究与开发

大坝安全监测仿真实验系统是一种动态模拟实验系统.介绍了大坝安全监测仿真实验系统的总体设计方案.其实验系统共分为两个部分:大坝形变模拟和大坝安全监测子系统,其中大坝形变模拟子系统选择了单机集中控制方案.采用快速高效、具有可视化控件编程功能的Delphi 7.0作为应用程序的开发工具.两个子系统之间存在通信信号,以便完成整套系统的全自动运行.此系统的开发成功,大大提高了水利水电动模实验室的自动化水平,方便了教学、科研和实验工作.     

小水库加固中的渗流分析及防渗方案选取

正1概述水库大坝渗漏对水库的危害极大,如其渗漏量较大,将使水库效益显著降低;降低软弱结构面强度,使某些岩土或断裂带充填物产生渗透变形;下游地下水位抬升、建筑物地基浸没、失稳;引起坝肩、坝体滑动等环境地质问题,严重的还会造成溃坝。因此做好水库大坝的防渗可以提高水库的综合效益,对保证大坝的安全运行,保证下游农田及居民的生命和财产安全起着举足轻重的作用。     

水口水电站大坝10.04.14洪水期监测资料分析

此次加密观测主要针对10.04.14洪水过坝期间,洪水历时较长,入库洪峰和泄水量都较大,溢洪设施运行频繁,环境气温多变,大坝运行工况总体较为复杂.为密切监视大坝运行情况,特对此次洪水过坝监测信息进行处理分析,准确的对测点测值进行计算统计,作出各点的过程线和极值分布图,对大坝安全状况进行分析判断.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
