纵横信息数字化 优化作文教学方法和教学模式的创新研究

1.利用纵横信息技术增加学生的知识积累 鲁迅说过:"必须如蜜蜂一样,采过许多花,这才能酿出蜜来."学生必须观察、阅读、大量的积累,写作时才会有话可说,有材可选,下笔才会有神,表达才会有个性、有特色.     

单标准阶梯减光摄谱法在钢分析中的应用

单标准阶梯减光摄谱法在钢分析中的应用张茂平,尹家愉（长城特殊钢公司第三钢厂,四川江油,６２１７０４）三标准试样法是光谱定量分析的基本方法,所需标钢不少于三个。我们在实际分析中常碰到一些根本没有整套标钢的各种样品,该方法就不适于这类样品。若能把光谱定量...     

A Study of Diamond-Like Carbon Thin Films Prepared by Microwave Plasma Chemical Vapour Deposition

In order to deposit good films, we need to study the uniformity of plasma density and the plasma density under different gas pressures and powers. The plasma density was diagnosed by a Langmuir probe. The optical emission spectroscopy （OES） of CH4 and H2 discharge was obtained with raster spectroscopy, with characteristic peaks of H and CH achieved. Diamond-like carbon films were achieved based on the study of plasma density and OES and characterized by atomic force microscope （AFM）, X-ray diffraction instrument （XRD）, Raman spectroscope and profiler.     

Optical Emission Spectroscopy of Electron Cyclotron Resonance-Plasma Enchanced Metalorganic Chemical Vapor Deposition Process for Deposition of GaN Film

An investigation was made into the nitrogen-trimethylgallium mixed electron cyclotron resonance （ECR） plasma by optical emission spectroscopy （OES）. The ECR plasma enhanced metalorganic chemical vapour deposition technology was adopted to grow GaN film on an α-Al2O3 substrate. X-ray diffraction （XRD） analyses showed that the peak of GaN （0002） was at 20 = 34.48°, being sharper and more intense with the increase in the Ne： trimethylgallium（TMG） flow ratio. The results demonstrate that the electron cyclotron resonance-plasma enchanced met- alorganic chemical vapor deposition （ECR-MOPECVD） technology is evidently advantageous for the deposition of GaN film at a low growth temperature.

1．利用纵横信息技术增加学生的知识积累 鲁迅说过：“必须如蜜蜂一样，采过许多花，这才能酿出蜜来。”学生必须观察、阅读、大量的积累，写作时才会有话可说，有材可选，下笔才会有神，表达才会有个性、有特色。那么，怎样在训练学生录入汉字的过程中让学生增加知识积累，起到事半功倍的效果呢？我们主要从三个方面引导学生：①利用纵横信息软件中的词语游戏软件，教师精心选择练习的词语，让学生在练习四字词时增加四字词语和成语积累。
