摘要
在"新工科"教育改革的大背景下,物理实验教学中可以引入更多包含"动手"训练的实验项目,本文介绍了新引进的扭曲向列相液晶盒制作与电光性能测试实验.除了介绍相对成熟的实验内容,包括制作步骤和开关电压、响应时间、视角特性测量等,还着重讨论了如何在实验过程中挖掘值得深入探究的内容.
Under the background of"new engineering"education reform,more teaching experiments containing"hands-on"training could be introduced into physics laboratory courses.The experiment of fabrication of twisted nematic liquid crystal(TNLC)cells and characterization of their electrooptical properties was introduced.In addition to introducing comparatively well-defined experimental contents,including the fabrication steps and the measurement of switching voltage,response time,and visual angle characteristics,etc.,special emphasis was put on how to identify topics worthy of indepth exploration in the experimental process.
