定向层 meaning in Chinese

oriented layer

2 pi coating : evenly covering the surface of the glass with a layer of pi fluid
2定向层涂覆：在玻璃表面均匀涂覆一层定向层。
3 pi rubbing : rub the pi layer with fine cloth to form curves so that lc molecules can be arranged in them according to relevant requirement
3定向层摩擦：用绒布在定向层表面摩擦出沟槽，以便液晶分子按照要求的方向进行排列。
In this paper , the reason of the break - off of the films is analyzed , and the problem has been solved . the function of the liquid crystal is modulating the read beam
液晶在液晶光阀中起着调制读出光的作用，液晶调制光性能的优劣与定向层的好坏，定向方式等密切相关。
The third , the orientational order parameters of the interface molecular layers can be greater or less than that of the bulk system , which is depend on the materials and physical processing conditions , and can apparently influenced by the n - i phase transition when the surface field is week
最后，视定向层的材料不同和物理处理条件不同，界面层上的分子取向序参数可以小于或大于液晶体内的序参数，且当表面作用较弱时液晶体内的n - i相变才会明显影响界面分子层上的序参数。
