离子束辅助沉积镍铬合金膜研究

分析了电子束沉积镍铬合金膜沉积的主要缺点,提出离子辅助电子束法沉积镍铬合金膜的新方法。利用氩离子辅助在微通道板表面沉积了镍铬合金膜,对比和分析了使用氩离子辅助沉积和电子束沉积薄膜的性质(附着力、致密性、表面电阻等)。结果表明,使用250eV的氩离子源辅助沉积的镍铬合金膜附着力好、结构致密、表面电阻低。     

高级程序设计语言课程教学改革与实践

在诸多高级程序设计语言课程中,C语言程序设计是比较难教和难学的一门课程.在分析该课程传统教学模式中存在问题的基础上,提出了采用分段教学、加强以算法为中心的程序设计内容、优化实验结构和采用网站辅助教学等改革建议.     

在金属表面络合网格状高分子膜实现滴状冷凝的MD模拟研究

提出了在铜表面络合上一种网格状高分子膜来实现水蒸汽滴状冷凝的新模型。预计这种单分子层的高分子膜可以被大片的配位键牢牢地粘附在金属表面上,并具有可自修复的特性,因而可望获得超长使用寿命和较高传热效率的滴状冷凝表面。根据相关的成膜或成滴的判据,用分子动力学模拟方法计算了水分子的内聚能和表面的吸附能。结果表明,在这种网格状高分子膜的表面上可以实现滴状冷凝。并且,通过观察粒子的平衡位型分布,可以看到网格状高分子中的大环结构可能起到核化中心位的作用。     

Computer‐based learning: Interleaving whole and sectional representation of neuroanatomy

The large volume of material to be learned in biomedical disciplines requires optimizing the efficiency of instruction. In prior work with computer‐based instruction of neuroanatomy, it was relatively efficient for learners to master whole anatomy and then transfer to learning sectional anatomy. It may, however, be more efficient to continuously integrate learning of whole and sectional anatomy. A study of computer‐based learning of neuroanatomy was conducted to compare a basic transfer paradigm for learning whole and sectional neuroanatomy with a method in which the two forms of representation were interleaved (alternated). For all experimental groups, interactive computer programs supported an approach to instruction called adaptive exploration. Each learning trial consisted of time‐limited exploration of neuroanatomy, self‐timed testing, and graphical feedback. The primary result of this study was that interleaved learning of whole and sectional neuroanatomy was more efficient than the basic transfer method, without cost to long‐term retention or generalization of knowledge to recognizing new images (Visible Human and MRI).

The effects of computer technology in assisting the development of literacy in young struggling readers and spellers

The aim of the present study is to evaluate the effect of MultiFunk, a computer program designed to assist reading, on the reading and spelling proficiency of struggling readers. Fifty‐two below‐average readers and spellers, in grades 5, 6 and 7, were randomly assigned as experimental and control groups (N?=?26?+?26). In addition, 114 classmates, who read normally, were included to compare changes in basic literacy development during the intervention. A pre‐test, intervention, post‐test, control‐group design was used to evaluate the effects of the software, using texts to suit the pupils’ own choices and interests. The findings indicate that computerized assistive reading has the potential to aid and support the development of basic literacy skills in a broad group of struggling readers and spellers. Issues concerning the MultiFunk text‐to‐speech technology are discussed.     

现代教学理论对多媒体辅助语言教学的影响
