Application of Information Entropy Principle to Uncertainty Calculation of the Arithmetic Mean Deviation(MD) of Surface Roughness 信息熵原理在表面粗糙度Ra不确定度计算中的应用
Arithmetical mean deviation of the ( roughness ) profile (粗糙度)轮廓的算术平均偏差(MD)
A Mean deviation Portfolio Optimal Selection Model 均值&离差型组合证券投资优化模型
Relative mean deviation of determined results of the sample is 0.26 %. 样品测定结果的相对平均偏差(MD)为0.26%;
This system can automatically calculate and display as well as print the arithmetic mean deviation of test-pieces measured. 本系统可自动计算、显示并打印被测试件的平均算术偏差Ra数值。
