approximation measurement method

基本解釋

介紹了筆者在流量計(jì)量實(shí)踐中所用過(guò)的逼近法和待定系數(shù)法。
This artical tries to apply this method to the measurement of mathematical medium and make a research with operators of approximation as an example.
本文應(yīng)用這一分析法衡量數(shù)學(xué)手段。竝以逼近論中算子爲(wèi)例進(jìn)行研究。
A series of Gaussian digital approximation filters used in roundness measurement were designed on the basis of approximation method and bilinear transformation.
文中用逼近法和雙線(xiàn)性變換法，設(shè)計(jì)了用於圓度測(cè)量的高斯數(shù)字逼近濾波器，竝給出了零相移的遞歸濾波算法，計(jì)算量小，計(jì)算傚率高，易於實(shí)現(xiàn)。
