1.Through the analysis of three-point method roundness error separation technique and based on the invariability and the periodicity of the geometrical characteristic of the measured round contour,a new matrix algorithm which can be used to solve the roundness error of the measured round profile directly without Fourier transform was presented.
通过对3点法圆度误差分离技术的分析和基于被测圆轮廓几何特征不变并具有周期性的特点,提出了一种不需要傅立叶变换、可直接求解被测圆轮廓圆度误差的新算法———矩阵算法。
2.The matrix method is employed to analyze the optical activity of liquid crystal, and the matrix presentation of optical rotation is given.
利用矩阵方法分析了液晶的旋光效应,导出了液晶旋光的矩阵表示.利用JG-3型连续可调谐磁场仪搭建实验装置,红外1350nm激光器做光源,测量了偏振光通过磁场作用下BL-009型向列相液晶的旋光角,详细分析了磁场对液晶旋光性能的影响.通过实验测试,对液晶的阈值磁场强度进行了讨论,同时对实验结果进行了理论上的分析,得出了液晶旋光角随磁场与液晶盒表面夹角而变化的结论,验证了液晶分子轴的旋转方向与磁场的方向无关,这为更好的研究液晶的特性以及液晶器件的设计具有重要的参考价值
