工业产品设计中的非物质形态--汽车梦的实现

工业产品需要充斥情感和符号的张力，使人和产品之间构成“自然合成”，这种合成的动态关系反映了工业产品使用的心理状态的变化，产品呈现为一种“边缘象征主义”特征，成为一种人们急欲得到的仪式性的物品。我们清晰地认识到在舒适性产品的后面隐藏着～种虚拟性假想，但这IF是生活世界的真实的需要，非物质设计的新思考是工业产品设计的重新命题。     

中国元素在工业产品设计中的切入研究

UGNX2.O环境下工业产品的逆向工程设计

逆向工程在当今工业产品设计过程中得到越来越广泛的应用。逆向工程是一种从模型对象表面获得的点云数据出发，使设计者能在计算机内生成一个已存在模型实物的替代品的技术。介绍了在UGNX2．0环境下进行工业产品逆向工程设计过程中的具体方法，并以实例的形式阐述了该过程的关键技术。     

敢于言败

教学人教版自然第十册第七课《二氧化碳的性质》时，学生通过观察实验认识了二氧化碳的性质：二氧化碳是一种无色、透明的气体，它不支持燃烧，比空气重，能使澄清的石灰水变浑浊。在认识到二氧化碳能使澄清的石灰水变浑浊的时候，学生把澄清的石灰水倒人装有二氧化碳的集气瓶，振荡过后     

小实验巧改进

在人教版自然第十册《二氧化碳》这一课中，有一则制取二氧化碳气体的实验，按教材中介绍的实验方法制取二氧化碳，效果不太好、不理想。用碱粉末与醋反应产生二氧化碳，实验时由于反应迅速和产气量不足，还没来得及完成收集气体的操作，产气即将终止，很难收集到较纯的二氧化碳气体，并且需要较多的原材料。如果用稀盐酸与我们这儿随处可见的石灰石反应，实验效果非常好：反应迅速、剧烈，实验明显；反应持续时间长，能让学生明显看到反应的现象（像沸腾一样接连不断地冒气泡）；产气量多，用的原材料较少。做二氧化碳不支持燃烧和二氧化碳…     

二氧化碳的性质和制法

1．二氧化碳的性质和用途（1）二氧化碳的物理性质：通常状况下二氧化碳是无色、无味的气体，密度比空气大，能溶于水，固体二氧化碳俗称“干冰”，干冰升华时需要吸收大量的热．     

工业产品设计与中国元素的契合研究

本文分析了中国元素在工业产品设计中情感需求的消费心理,阐明了工业产品设计的国内外发展历程,从形态、意韵、材质、装饰纹样等方面,对中国元素与工业产品设计的契合进行了深入研究。     

二氧化碳性质教学与实验的改进

人教课标教材九年级化学第六单元课题3《二氧化碳与一氧化碳》，关于二氧化碳的性质，教材对义务教材中部分实验内容作了修改，与新教材上一版本也有差异。在可感受性和趣味性方面较旧教材有大的改进，如二氧化碳的溶解性、二氧化碳与水的反应等。下面，

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.
