1) deviation mean
偏差均值
1.
In this paper the authors not only extend Daroczy s deviation and deviation means but also obtain some weak sufficient conditions for a family of deviation means to be convergen
本文推广了Ｄａｒｏｃｚｙ的偏差与偏差均值的概念，给出这种偏差均值和偏差近代均值收敛的充分条件，所给条件都是相当弱的。
2) mean bias
均值偏差
1.
Results show that the mean bias and variance of.
结果显示新方法的估计均值偏差和方差均小于SC方法。
3) average value deviation
平均值偏差
1.
On the basis of making testing and verifying reports of national standard parameters, the definition method and some experiments data of average value deviation and standard deviation of roughness comparison specimens for plastic parts are discussed, and some problems in testing surface roughness for plastic parts are raised.
在制定国家标准———塑料件表面粗糙度比较样块的参数测试、验证报告基础上，总结了塑料件表面粗糙度比较样块平均值偏差和标准偏差的确定依据，对实验数据进行了分析，指出了塑料件表面粗糙度测量中存在的问题及解决办法。
5) average velocity deviation
速度偏差均值
6) offer-average-warp-rate
报价均值偏差率
1.
From the statistics law of offers that offer-average-warp-rate has statistics normal distribution under rational low price evaluation method, the effective range of offers and the average of offers is determined according to slight probability and the dynamic subduction coefficient is determined according to competition.
投标报价中报价均值偏差率服从正态分布,按照小概率原则确定有效报价范围和报价平均值,并按照竞争性原则确定动态下浮系数,这样既反映市场情况又避免人为因素,由此得出的评标基准价更具合理性,可以有效防范围标串标。
补充资料：均方偏差
分子式：
CAS号：
性质：简称均方差。是样本中各个测定值xi对样本平均值x的差值平方和除以测定次数n，以表示。它不是总体方差σ2(x)的无偏估计值。
