《数据结构》是计算机等专业一门重要的专业基础课,是程序设计的重要理论基础,也是多门后续课程的学习基础.本文针对当前数据结构实验教学中存在的问题,提出了针对不同学生学习阶段要求完成基础性实验、自选性实验、设计性实验、综合性实验的分层次实验教学,有效提高学生的实验能力和学习积极性.     

基于CITYgreen模型的厦门城市森林生态效益研究

基于Arcview 3.3程序和CITYgreen 5.0模型对厦门市厦门岛、鼓浪屿两岛屿城市森林进行生态效益价值评价研究,并对3种不同类型城市森林生态效益进行对比研究.结果表明：两岛屿林地占有面积约为3.25＆#215;103 hm2;城市森林通过吸收碳和清除大气污染物所产生经济价值总共约为1.29＆#215;103万元;3种类型城市森林碳储存量和碳吸收量以及清除大气污染物效益从大到小均依次为：自然林类型、城市公园类型、绿化带类型,以对O3清除能力最强.研究结果为厦门城市森林规划和建设提供科学参考.     

雨水综合管理规划、评价和实施:以上海为例(英文)

提出了一套基于低影响开发理念的城市雨水综合管理规划方案.与传统排水规划不同,该方案通过在社区尺度上规划各类低影响开发设施,削减径流总量和污染负荷,实现可持续的城市雨水综合管理.采用结合了传统排水管道和低影响开发设施的水力模型,对规划效果进行了评价.通过20年降雨数据的连续模拟发现,在规划完全实施基础上,相对于不采用低影响开发设施,径流总量削减率可达80%以上.为保障和指导规划的实施,结合当地条件,制定了技术实施导则.规划区域内3条主干道道旁生物滞留设施已完成施工建设,区域内其他地块的开发也正在实施导则的指导下逐步开展和实施.提出的基于低影响开发理念的区域雨水综合管理规划、评价和实施方法,将为我国其他地区的类似项目提供经验和借鉴.     

城市规划地理信息系统的设计与研究

针对目前城市规划过程中,基础数据在存储、管理、应用中存在的问题,以及规划工作者在规划过程中空间分析方法的局限性,利用SuperMap Objects组件式GIS为二次开发平台,微软Visual Basic6.0为二次开发语言,设计开发了城市规划地理信息系统.系统的开发与应用不仅给城市规划部门了解、规划城市提供了全新的技术手段,而且系统的空间分析功能可以提高认识城市本质的能力,为＂数字城市＂打下良好基础.

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?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

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.
