对外汉语教学中的空缺理论应用与空缺消除方法的探讨

本文从对外汉语教学的角度介绍了空缺现象的存在，并从留学生的视点阐述了空缺既为学习难点同时也是汉语学习上的兴趣所在。根据教学实践，本文提出了新的空缺消除的方法一“连续集中授课法”，这种方法将为对外汉语教学的改善提供一个良好的平台。     

QUANTIFYING THE GENDER GAP IN SCIENCE INTERESTS

Nearly 5,000 self-generated science-related K–12 students’ questions, classified into seven science subjects, were used to quantitatively measure the gender gap in science interests and its change with age. In this data set, a difference between boys’ and girls’ science interests did not exist during early childhood, but increased over 20-fold by the end of high school. Furthermore, the gap widened in a stereotypical manner, with girls being increasingly interested in biology and boys more interested in physics and technology. This method could be applied for identifying and comparing the gender gap in science interests between different populations based on different data sources.

GAP: a Graphics Authoring Package which produces BASIC from graphical input

The authors argue that there is a need for a microcomputer software authoring package which produces graphics. The novel feature of the Graphics Authoring Package (GAP) which they developed is that it produces Basic code from the user's graphical input. GAP is described together with the results of an evaluation study. The results indicate that the package is easy to use, effective in rapidly producing graphics code and that, in general, it fills a gap in the current range of educational software.     

Zr_(52．5)Al_(10)Ni_(10)Cu_(15)Be_(12．5)大块金属玻璃的高温宏观硬度

The hot hardness behavior of Zr_(52.5)Al_(10)Ni_(10)Cu_(15)Be_(12.5) bulk metallic glass is studied from ambient temperature to the temperature over T_x (the onset crystallization temperature) using a hot macro-hardness tester and scanning electron microscopy (SEM).The results show that the hot hardness behavior of Zr_(52.5)Al_(10)Ni_(10)Cu_(15)Be_(12.5) bulk metallic glass can be classified into 4 zones:the glassy zone in which the hardness almost linearly decreases with the increase of temperature,the viscoelastic zone in which the hardness is nearly unchanged,the viscous flow zone in which the hardness quickly tends towards near zero with temperature,and the crystallization zone in which the hardness sharply increases.The high temperature deformation behavior and the easy processable deformation region for bulk metallic glasses are also discussed on the basis of the hot marco-hardness.     

从教育事业角度来看城乡差距--简论我国当前县乡教育事业发展的差距

城乡差距较大是中国的现实国情。造成这种现状的原因是多方面的。既有历史原因,也有现实原因;既有物质原因,也有精神原因。农村社会的落后阻碍了农村教育事业的发展,农村教育事业的滞后又延缓了农村社会的发展。通过分析县乡教育事业之间的差距,使人们能够正确认识到当前我国城乡之间的差距。     

Synthesis of Protected Tetrapeptide, N-o-Ns-N （Me） - Val-N （Me） -Val-N （ Me ） -Val-N （Me） -Phe-O^tBu

The protected tetrapeptide, N-o-Ns-N （ Me ） -Val-N （ Me ） -Val-N （ Me ） -Val- N （ Me ） -Phe- OtBu, was prepared from L-valine and L-phenylalanine. Ted-butyl acetate and HClO4 were used to protect carbonyl group, o-nitrobenzenesulfonyl chloride and triethyl amine were used to protect amino group, and N-alkylation was finished with iodomethane. Then the protected amino acid was turned into acid chloride which was taken as coupling reagent. After 14 steps, such as protection, alkylation, deprotection and coupling, the protected tetrapeptide was obtained with a yield of 26.9%. The structures of intermediates and target compound were identified with NMR spectra and high resolution mass spectra.

《金刚经》与南宗禅——以敦煌文献为中心

<金刚经>是唐代最流行的佛教经典之一,主要宣扬般若性空之理,对南宗禅的形成与发展起到了非常重要的作用.<金刚经>被六祖慧能奉为禅宗顿悟派的根本经典,神会在继承和发展慧能的顿悟禅法思想的基础上,建立了以<金刚经>为相互传承的南宗祖统说,以抗衡北宗掸以<楞伽经>为基础的祖统说,为南宗禅立宗弘法奠定了理论基础.在敦煌文献及唐代莫高窟壁画中有很多的<金刚经>写本及根据该经内容而绘制的经变画,体现了该经在唐代的盛行.这种现象的出现,应与以<金刚经>为主旨的顿悟禅法思想在敦煌的流行有关.
