孔罩

A three-mask chip process was first attempted in this work, where the 3rd mask was designed to evaporate the identical metal films for p- and n-pads. However, it was found that the Cr film showed inferior adhesion property on the ITO current spreading layer after the peeling test. In order to overcome this problem, a contact aperture was opened in the mask of ITO layer.

改为三道光罩后，P、N电极使用同一道光罩，并蒸镀相同的金属，但实验后发现，铬和氧铟锡的附著性并不好，经黏贴测试后，发现有电极剥落的情形，所以我们在透明导电层的光罩上，做了个圆孔的设计，这个圆孔的设计可以得到二个优点。

本文研究的防堵防跑双罩式内循环流态化水冷器的结构特点是：底室采用泡罩板加大孔均布板取代筛孔容易堵塞的筛板；水冷管出口安装挡粒调匀罩。

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。
