研究基于自主研发并已投入运行的超高纯氪氙分离低温精馏系统的实验数据，在 COMSOLMultiphysics 软件利用非等温流动和多孔介质中的稀物质传递模块建立极低浓度下波纹规整填料PACK-13C 的 REU 模型，利用化学模块描述不同温度、压力和浓度下的气液物性，通过Delft模型计算得到气液间传质系数，利用传质通量边界和边界热源模拟气液界面上的传质传热现象，分析气液两相传热传质特性，研究极低浓度(<e-7 mol/mol)下的气液传质过程，并通过改变填料几何结构进行优化分析。 模拟结果显示REU模型能较为准确地表征填料液膜上的浓度变化 ... En savoir plus

Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... En savoir plus

The electronic wheel detector is a device that has been widely used at SNCF Company for train passage detection, which constitutes a primary task in coordination of trains' signalization. The detectors have been deployed in the company for at least three decades; however, some trouble ... En savoir plus

Induction motors have wide applications in industries, so they are prone to faults, which later result in vibrations and hence noise. So it is important to analyze the faults in induction motors, their causes, and their effect on the system. Basically, there are so many faults in ... En savoir plus

Ultra-cold atom systems are excellent probes for various physical properties such as gravity, rotations or magnetic and electric fields.
