摘要
建立了叶片厚度仪的实际传动特性方程,通过与理论的线性模型比较,获得了仪器的原理误差函数式。并且分析了测量时接触变形误差对测量结果的影响问题,在此基础上提出了减小原理误差的方案,并以增加测量臂长为例论述了减小原理误差的方法.
An equation of actual transmission characteristics for plant leaf thickness instruments is established in the paper. By a comparison between the equation and theoretical linear model, the theoretical error function of the device is got. Authors analyze the problem about how errors of contact deformation in measurement impact survey results. On the basis of the above-mentioned work, the program to reduce theoretical errors is put forward. Taken as an example, the method to reduce theoretical errors is discussed by means of increasing the length of the measurement arm.
