摘　　要：通过理论分析和实验研究液晶分子附着能和液晶盒间隙对响应时间(τ0)的影响。用液晶盒有效间隙法和表面动力学方程法两种方法推出分析公式,由这两种方法推出的结果是一致的。实验数据与简化方程τ0-dx基本拟合(其中d是液晶盒的间隙,x是指数)。在两种极端的(极大或极小)附着能极限下,指数x分别接近2和1。这个结论有助于优化液晶显示器件的应用。The anchoring energy and cell gap effects on liquid crystal response time （τ0） iS analyzed theoretically and validated experimentally. Analytical expressions are derived using two different approaches： effective cell gap and surface dynamic equation methods. Consistent results are deduced from these two approaches. A simplified equation τ0- d^x also fits the experimental data well, where d is the liquid crystal cell gap and x is the exponent. Under two extreme （strong and weak） anchoring limits, the exponent x approaches 2 and 1, respectively. This information is helpful for optimizing liquid crystal devices for display applications.
