It is thus very impotri to understand how ece promotes the whole - child development of learners in order to help them to develop the knowedge , attitudes and sidlls needed to function effectively in our rapidly changing and multicultural society and beyond 因此，在迅速变化及多元文化的世界里，幼儿教育课程是否能有效地促进儿童全人发展，使他们获得未来世界公民所具备的知识、态度和技能，意义重大。
( 1 ) at first , the conception of egis is put forward . and some basic techniques of it are discussed , including the integration of the applied numerical model with gis , the research of creating dem ( digital elevation model ) and the application of dem in ece 本文的主要研究内容是： ( 1 )提出建立工程地理信息系统egis ，并进行一些基本方法的探讨，包括应用模型与gis集成模式的讨论，数字地面模型生成的方法比较和应用。

With the mathematics models of the lithium ion battery and ac motor , the approach and magnitude of energy consume of the whole vehicle are analyzed under the conventional theory of automobile in this paper . at the same time , the relation between the energy consume and the charge and discharge voltage and current of the battery , as well as that between the energy consume and the voltage and current of the motor stator are made clear on the basis of ece drive mode 文章从传统的汽车理论出发，结合锂离子动力电池和电机的数学模型，分析了纯电动汽车整车的能量消耗途径和大小；基于欧洲ece循环驱动模式，建立了纯电动汽车的功率消耗与电池的充放电电压、电流以及电机定子电压、电流之间的关系，并在此基础上分析了纯电动汽车的续驶里程和制动能量的回收问题。
On the basic of a great of literature reading and research on safety of side impact of the car , according to requirement of ece r95 , applied madymo6 . 2 . 1 software , established simulation model of side impact of the car , researched the relationship between side rigidity of the car and passenger injury in side impact , which showed that during first impact the bigger side rigidity was , the more advantaged protection for the car and passenger in a definite range , and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact . then detailed the substructure model by defining bodies , joints , contact types and contact characteristic , researched some improvement approach for side safety of the car , and then analyses a particular case , that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door , analyzed the influence of passenger injury when the bar fender was fixed on different position , the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar . finally , a set of tests were performed , contrasting the simulation result with the test , analyzed the influence of the side rigidity of the car to passenger injury , which showed the test 本文在对汽车的侧面碰撞安全性进行大量文献阅读和研究的基础上,按照欧洲ecer95侧面碰撞乘员保护法规的要求,应用多刚体动力学软件madymo6 . 2 . 1 ,建立了汽车的侧面碰撞仿真模型,研究了汽车的侧面刚性对乘员损伤的影响,结果表明在“一次碰撞”中,在一定范围内汽车侧面刚性越大,越有利于汽车和乘员的保护,同时得出结论,即在“一次碰撞”过程中人体损伤最严重的部位是骨盆;然后通过定义各刚体、铰链、接触类型以及接触特性,对该模型进行子结构细化工作,研究了加强汽车侧面安全性的若干改进措施,并进行了一个特例分析,即在此模型的车门内外板之间安装了车门防撞杆,分析了当车门防撞杆安装在不同位置时对乘员损伤的影响,结果表明防撞杆位于车门装饰条的高度时,对乘员的损伤较小;最后进行了一组侧面碰撞试验,通过试验和仿真结果的对比,分析汽车的侧面刚性对乘员损伤的影响,表明试验和仿真结果是一致的,从而证明了仿真模型的有效性以及仿真结果的正确性。
At present , many fields remain to further research , especially the profound combination of gis technique with ece ( estuarine and coastal engineering ) , which should be developed for the purposes as follows : ( 1 ) to serve the huge comprehensive work in changeable natural conditions and difficult construction conditions which takes a long period and covers a large region , e . g . the regulation work of deepwater channel in the yre ( yangtze river estuary ) ( 2 ) to combine the gis with applied numerical model ( 3 ) to study the hydrodynamic processes and characteristics of waves , tidal currents and sediment transport , as well as the affection carried by the regulation work in an estuary ( 4 ) to monitor and to analyze ees ( evolution of erosion and sedimentation ) and the variation of riverbed ( 5 ) to play a role of dynamic supervising of a engineering project 目前尚有许多有待进一步研究的领域，尤其是以服务于长江口深水航道治理这样规模大、周期长、影响区域广、自然条件复杂、施工情况多变的国家重点工程为目的，将gis与专业应用数学模型结合，对河口海岸波浪、潮流、泥沙运动的动力机制，以及整治工程建筑物对其影响的研究，对入海航道冲淤和河势演变的监测分析，对施工进展和工程效果实现“动态”监控和管理，尚缺乏同gis技术的深入有效结合。
