区域产业扩张与国际产业转移作为区域产业传递的两种基本形式，由其各自的特点决定了对欠发达地区的不同影响；西部地区应以区域经济联系和空间联系体系的建立应对“第二次产业西移”，应以资源优势战略实现模式的转换推进本区域产业的扩张。  相似文献   

Measurement of conversion efficiency of soft X-ray from 0.35μm laser-irradiated aluminum planar targets

Conversion efficiency of soft X-ray from 0.35 μm pulse laser-irradiated aluminium planar target at laser intensities 10¹³–10¹⁵ W/cm² on the Xingguang-II facility (laser energy 5–90 J, focal spot ⊃ Ф 200 μm full width of half maximun (FWHM) 400–800 ps) was measured. A simple model was given to explain soft X-ray conversion efficiency. In this model, because of the heat conduction from the laser-heated spot, the conversion was very small at lower irradiance limit, while at higher limit it was bounded by the energy lost in blow off plasma. Consequently, at the laser intensity around 2×10¹⁴ W/cm², the X-ray conversion efficiency reaches a maximum.

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective     

Bart Rienties  Bas Giesbers  Simon Lygo-Baker  Hoi Wah Serena Ma  Roger Rees 《Interactive Learning Environments》2016,24(3):539-552

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.  相似文献   

“科尔曼报告”述评——兼论对我国解决“上学难、上学贵”问题的启示   总被引：1，自引：0，他引：1  

马晓强 《教育研究》2006,(6)

“科尔曼报告”是在二战后随着教育平等、教育民主化思潮的出现以及美国民权法案对教育机会均等现状调查的要求而产生的。报告对美国教育机会均等的现状和影响因素进行了科学的分析,认为校际间差距对不同种族的学生有不同的影响,造成儿童学习水平低的原因,主要不是学校的物质条件,而是学校内的社会因素。“科尔曼报告”深刻地影响了教育机会均等的理论研究与政策实践,对分析和探讨当前我国“上学难、上学贵”问题具有重要的借鉴意义。  相似文献

Development of a plastic injection molding training system using Petri nets and virtual reality     

马斌  郭志英  周华民 《浙江大学学报(A卷英文版)》2006,7(3):302-308

INTRODUCTIONAt present, plastic as a substitute for metals in products is the most important mainstay in industrial raw materials. Furthermore, plastic injection molding is one of the most common and versatile methods for mass production of complex plastic parts with excel-lent dimensional tolerance. Since the technology of injection molding has been widely applied in manu-facturing, training on injection molding is of great importance. The traditional approach is to consult some technica…  相似文献
