搞好环境价值评估 促进社会和谐发展

<正>近年来,人们已逐渐认识到环境具有价值,市场、政策和法律的协调使得部分环境价值已得到体现,但由于目前对环境科学认识的片面性和环境经济价值评价的不确定性,使人们仍不能完全明白环境的真正价值,不能实现高效率的经济发展和公平的资源分配。为此,需完善环境价值评估体系,促进经济、环境和社会的协调发展,建立环境友好型社会,实现和谐社会目标。     

论中国古代的优秀德育传统及其现代意义

在德育教育方面，古代中国为今人留下了丰富的精神遗产，形成了优秀的德育传统，这具体表现在以下三个方面：重视德育的优良传统；对德育过程的科学认识，对德育原则和方法的一系列精辟见解，继承这些优秀德育传统是21世纪中国学校德育发展的必然选择，在继承的基础上不断创新，是21世纪中国学校德育发展的基本路向。     

科学认识细菌--读《细菌世界历险记》有感

专家告诉我们要经常洗手,杀灭病毒和有害细菌。病毒,我已经了解了一些。细菌到底是什么?它在哪里?……带着这些疑问,我阅读了高土其的《细菌世界历险记》。高士其是我国著名科学家、科普作家和社会活动家。     

作为客体的科学仪器

传统的科学认识论一般凸现了科学仪器在科学认识过程中的中介作用,忽视了科学仪器使用过程中的具体复杂性,将科学仪器当作科学认识的工具和桥梁。其实,在科学认识过程中,仪器的使用具体的、不充分的、开放的,仪器的呈像是可错的,仪器是与认识对象有着复杂关联的。这就决定了科学仪器既是科学认识的工具,又是科学认识的对象,经过人的现实的对象性活动制造出来后,在其使用过程中被深刻地认识的对象,扮演着科学认识工具和科学     

Research progress in ZnO single-crystal: growth,scientific understanding,and device applications

Zinc oxide, a wide band-gap semiconductor, has shown extensive potential applications in high-efficiency semiconductor photoelectronic devices, semiconductor photocatalysis, and diluted magnetic semiconductors. Due to the undisputed lattice integrity, ZnO single crystals are essential for the fabrication of high-quality ZnO-based photoelectronic devices, and also believed to be ideal research subjects for understanding the underlying mechanisms of semiconductor photocatalysis and diluted magnetic semiconductors. This review, which is organized in two main parts, introduces the recent progress in growth, basic characterization, and device development of ZnO single crystals, and some related works in our group. The first part begins from the growth of ZnO single crystal, and summarizes the fundamental and applied investigations based on ZnO single crystals. These works are composed of the fabrication of homoepitaxial ZnO-based photoelectronic devices, the research on the photocatalysis mechanism, and dilute magnetic mechanism. The second part describes the fabrication of highly thermostable n-type ZnO with high mobility and high electron concentration through intentional doping. More importantly, in this part, a conceptual approach for fabricating highly thermostable p-type ZnO materials with high mobility through an integrated three-step treatment is proposed on the basis of the preliminary research.

Ten years＇ venturing in ZnO nanostructures： from discovery to scientific understanding and to technolosy applications

Zinc oxide is a unique material that exhibits semiconducting, piezoelectric and pyroelectric multiple properties. Nanostructures of ZnO are equally important as carbon nanotubes and silicon nanowires （NWs） for nanotechnology, and have great potential applications in nano-electronics, optoelectronics, sensors, field emission, light emitting diodes, photocatalysis, nanogenerators, and nanopiezotronics. Ever since the discovery of nanobelts （NBs） in 2001 by my group, a world wide research in ZnO has been kicked off. This review introduces my group＇s experience in venturing the discovery, understanding and applications of ZnO NWs and NBs. The aim is to introduce the progress made in my research in the last 10 years in accompany to the huge social advances and economic development taking place in China in the last 10 years.
