GPS型双层高频振动细筛为二路给矿,具有二层筛面,GPS—1200—2型和GPS—1400—2型两种规格的筛面宽度分别为1200mm和1400mm。试验表明,双层高频振动细筛与单层高频振动细筛相比,可以提高细筛的处理能力和延长筛网使用寿命。本文介绍了设备的结构特点。给出了实际应用的结果。     

Enhancing classification capabilities of computer screen photo-assisted fluorescence fingerprinting

The separation of emission from transmitted light for the fingerprinting of fluorescent substances using a computer screen photo-assisted technique (CSPT) is demonstrated. CSPT is a technique for optical evaluation using a simple cell with just a standard computer set and a web camera as instrumentation. It has been demonstrated to be a versatile system for colorimetric and fluorescent fingerprinting. Here the omnidirectional property of fluorescent emission is utilized to separate it from the background, using a simple optical arrangement compatible with CSPT purposes. This enhances the classification capabilities and makes classification at sub-μM concentrations possible.

Experimental study of the flow boiling heat transfer enhancement and pressure drop due to the bubble behavior restricted by a screen sheet

A unique method previously proposed by the authors was applied to the heat transfer augmentation in the flow boiling field. In this method a screen sheet was placed on the horizontal heated surface where bubble nucleation occurred. Generated vapor bubbles were trapped between the screen and the wall, became flat, and moved along the surface. This restricted bubble behavior caused the heat transfer enhancement. Three types of screen sheet were tested in the present experiment and the effect of the screen on the heat transfer and two‐phase flow characteristics was investigated. In two of these cases, the screen was displaced upward by the bubble nucleation. Compared with the ordinary flow boiling case, heat transfer was enhanced by a factor of 1.2 to 6 within the present experimental range. Using a simple flow model, it was made clear that the effect of the height of the displaced screen was important in evaluating the increase in pressure drop. © 2003 Wiley Periodicals, Inc.

粘接炉中空气回流板的应用

把屏和锥用低熔点玻璃膏粘接起来的工艺是彩色显像管生产中的一个主要工序。在粘接的同时，把涂屏工序中所用的腊克等其它有机物烤掉，最后将屏锥粘接一起成为玻壳。怎样依据低熔点玻璃膏的特性，控制一条保证产品质量的温度曲线是保证粘接质量，少出废品的关键，本文提出在原ＳＭＩＴＨ公司生产的粘接炉内加装回流板的措施，实现了提高产品合格率和节能的双重功效。
