一、液晶介绍1.何为液晶(1)在研究世间物质的形态时,人们有一种共同的认识,物质有三种状态:固态、液态和气态。如图1所示。固态是一个分子很靠近且整齐排列的状态。液态中的分子虽然很靠近,但不具有空间上排列的秩序性。气态中的分子则相互间分离的很远。液体具有不同的态。液 First, the introduction of liquid crystal 1. What is liquid crystal (1) in the study of the material form of the world, people have a common understanding of the material has three states: solid, liquid and gas. As shown in Figure 1. Solid state is a state in which molecules are close and neatly arranged. Although the molecules in the liquid are very close, they do not have the orderly arrangement in space. The molecules in the gas are far apart from each other. Liquids have different states. liquid
