液晶的发现已经有一百多年的历史了.然而在未曾找到其实际用途之前,长期仅停留在少数科学家的实验室里,被当作珍品做一些探索性的实验研究.到本世纪30年代中期科学家们对液晶的合成及其重要物理特性才积累了一定的
The discovery of liquid crystal has been more than a hundred years old, but until it was not found in any practical use, it remained in the lab of a few scientists for a long time as a exploratory experimental study of treasures. By the 1930s Mid-term scientists on the synthesis of liquid crystal and its important physical properties have accumulated a certain amount
