汉字形音义之间的关系及其影响

汉字形、音、义之间互相交叉 ,互相作用 ,形成异体字、异读字、多义字、同音字、同形字等复杂多样的现象。对非汉语文化圈的人来讲 ,如果不了解汉字的音形义这种复杂的交叉关系 ,学习汉字乃至汉语就会产生很大的障碍     

DNA: From Carrier of Genetic Information to Polymeric Materials

Research has shown that the DNA molecule can not only store genetic information but also serve as a polymeric biomolecule for the fabrication of functional materials. The unique precise molecular recognition capability and sequence programmability, combined with its good biocompatibility and biodegradability, impart the DNA molecule considerable potential for use in the construction of multifunctional materials. Depending on the composition, DNA-based materials have been generally categorized into pure DNA materials that are entirely composed of DNA and hybrid DNA materials that are composed of DNA and other functional compositions. Recently, we have developed a series of DNA-based materials that can be applied in diagnosis and therapy, and this review summarizes the relative work. Although challenges still exist regarding the real applications of DNA-based materials such as the high cost of DNA, the difficulty in scale-up, and the low resistance to nuclease, we believe that these drawbacks will be overcome with the development of technology, and new opportunities will emerge in the field of diagnosis and treatment.     

中职教师在职攻读硕士学位问题探讨

近年来,中职教师在职攻读硕士学位的过程中,出现了许多不尽人意之处,如学员学前背景、学前动机、学中态度、学中效果、学后质量等差异较大,影响了培养质量。为此,有必要加强与学员所在单位的联系与合作;加强对学员的管理与规范;以人为本,全面提高学员综合素质和学术价值观;优化导师的整体指导资源,提升导师小组的指导能力。     

Visualization of structured packing with laser induced fluorescence technique: Two-dimensional measurement of liquid concentration distribution

A method of using laser induced fluorescence(LIF)technique was applied to two-dimensional measurement of the liquid concentration distribution in the 250Y structured packing sheet. The experimental structured packing sheet was made of perspex so that the laser could pass through it. The visualization of the distribution of the liquid concentration in the structured packing sheet was realized. The calibration of the thickness and liquid concentration was carried out firstly and the regression formula I=kcd was acquired, in which concentration c and the liquid film thickness d were both considered. Then the liquid feed of uniform tracer(rhodamine)concentration entered the perspex structured packing from the top under different spraying densities. The corresponding thickness of liquid film on the packing was calculated. Finally, tracer(rhodamine)with a high concentration was injected only at one fixed point of the structured packing under different spraying densities of the liquid. With the known liquid film thickness, the concentration distribution of the tracer can be calculated inside the structured packing sheet.     

高校公共体育课如何应对扩招

近年来高校因“扩招”导致学生人数激增，追成了体育场地严重不足，体育师资力量薄弱及教学工作量严重超标等问题，客观上给体育教学带来了巨大压力。因此，高校在加大场馆建设力度的同时，应积极拓展新的教学内容并合理安排教学时间，努力提高师资队伍水平。     

远程教学中"课堂搬家"两种技术实现方式的比较与分析

随着教育需求的不断增长，对学习资源特别是录制好的“课堂”电子类学习课件的需求也日益增加。近年，“网视宝”录制软件在课堂的现场录制、网上直播方面发挥着较大作用，提高了录制课堂、传播课堂的效率．有救解决了学习资源的供需矛盾；现在PowerPoint的联机广播功能也能够以一台计算机完成以前要靠网视宝、摄像机、计算机协同才能完成的任务，进一步降低了课堂录制、直播的成本，提高了效率，增加了课堂录制时间、地点上的灵活性，本文从经济性，操作性与技术性三个方面对这两种实现技术进行详细的比较与分析。

高技能人才培养课程体系的设计与实践

当前，部分高职院校现行课程体系设计缺乏针对性，培养目标定位模糊，在推行“双证制”过程中存在课程内容交叉重复、教育资源浪费等问题。为培养高技能人才，高职课程体系设计必须凸显办学特色，强调能力培养，强调优化、整合教育资源，实现学历教育与职业资格培训的一体化。为达此目标，课程内容的选择可依照国家职业标准，课程排序可参照职场工作流程。     

从知识管理看翻译中文化信息的失落与变形

知识管理是企业界一个新的管理理念。将知识管理的理念应用于翻译,讨论文化传递中文化信息的失落与变形是一个较新观点。翻译的过程是知识管理的过程,任何文化信息的失落与变形都是知识管理的结果。如果异域文化的产品被当做资产来管理、利用、创造和投资,那么对翻译的知识管理将会变得积极和敏锐。
