《Flash动画制作》公选课教学改革研究与实践①--以常州工学院为例

随着高等教育的不断发展,公共选修课教学已变得越来越重要。它可以开阔学生视野、拓宽学生知识面,全面提升大学生素质。但是,公选课受教学时间、学生来源、教学资源等各种条件的影响,教学效果差别较大。《Flash动画制作》公选课对实践性要求较高,如何提高这门课程的教学质量,是一个值得研究的问题。该文以常州工学院为例,分析了《Flash动画制作》公选课教学现状,从教学目标、教学模式、教学内容、考核方式等方面进行了研究,并在实践中取得了较好效果。

一种支持FAT文件系统的Flash转换层设计

针对Nand Flash先擦除后写入,block为最小擦除单位,page为最小读写单位,文档分配表文件（file allocation table,FAT）系统不能直接应用于Nand Flash的特点,提出一种基于缓存机制的应用于FAT文件系统的Flash转换层,设计一种逻辑块和物理块的映射机制处理Nand Flash的坏块;应用一种缓冲机制来提高系统读写速度,减少Flash存储块的擦除次数;应用循环冗余码校验算法(cyclical redundancy check,CRC)来改善Flash的负载平衡。本系统的闪存转换层（flash translation layer,FTL）有效地处理了Nand Flash的硬件限制,延长Flash的寿命。

Cyclisation at very high temperature. Thermal transformations of N-alkyl and N,N-dialkyl cinnamic amides into pyrrolidin-2-ones under FVT conditions

Novel cyclisations of N-alkyl and N,N-dialkyl cinnamic amides to the corresponding pyrrolidin-2-ones under the conditions of flash vacuum thermolysis, are described. It was found that this reaction proceeds at 950-1000 °C affording a mixture of isomeric pyrrolidin-2-ones in various yields. Two possible mechanisms are proposed for the process.     

Sample evaporation in conventional split/splitless GC injectors: Part 2: Use of perylene for visual observation of three different scenarios in empty injector inserts

Perylene is strongly fluorescent as long as it is in solution. This has enabled visual observation of non-evaporated sample material in a “transparent injector”, i.e. in a heated glass device imitating a conventional vaporizing injector. Three scenarios of sample evaporation are described. Some samples (solvents) are nebulized and “flash evaporated” in the gas phase between the needle exit and the column entrance (Scenario 1). With most solvents, the liquid leaves the syringe needle as a thin jet which rushes through both the empty vaporizing chamber and the split outlet at high velocity, often without substantial evaporation. It does not touch the surfaces of the insert and passes round the bend at the bottom of the device without any problem (Scenario 2). Some samples are splashed on to the insert wall, wet it, and evaporate rather slowly from this surface (Scenario 3).     

Determination of biogenic quaternary ammonium compounds on fused silica capillary columns with a splitless injector as a chemical reactor/pyrolysis chamber

A conventional splitless injector is used as a pyrolysis chamber or chemical reactor for the N-demethylation of acetylcholine and other choline esters. The novel uses of 2-aminoethanol as a N-demethylation reagent in splitless injection and bonded-phase fused silica capillary columns in the separation of the tertiary amine derivatives of choline esters are described. A comparison is made between non-polar and moderately polar fused silica capillary columns in the separation of choline esters.
