1.The principle of predicting SRL by capacitance in water was analyzed mathematically, which was simulated to prove the relationship between periodical non-homogeneity and SRL using MATLAB. In this paper, some methods of capacitance measurement were described.
数学分析了利用水电容的信息预测SRL的原理,通过MATLAB模拟水电容和SRL的关系可以验证不均匀点处阻抗的频率特性对SRL的影响;收藏指正
2.The test mechanisms of capacitor evenness tester and EIB photoelectric yarn appearance tester are analyzed. The capacitor evenness tester gives out the mean volume or mass of yarn section in test scope, but the EIB photoelectric yarn appearance tester reveals the diameter variation of yarn projection area, these two methods reflect the different property of yarn evenness, and their results are not in be in accordence.
分析了电容式条干均匀度仪和EIB光电式纱线外观测试分析仪的测试原理 ,指出 :电容式条干均匀度仪测试的是测量区内一段纱条的体积或质量的平均值 ,而EIB光电式纱线外观测试分析仪测试的是纱线某一投影面上的直径变异。 两者反映了纱线条干均匀度不同的内容 ,不完全一致收藏指正
