在很多场合只好用有间隙采样做阿仑方差，然后用巴勒斯偏函数加以修正，其繁杂程度是可想而知的。
In many cases, Allan variance has to be measured with dead time and then modified with Barnes bias function.
在区域化探中必须应用三层套合方差分析对样品的采样误差和分析误差进行统计分析。
In local chemical exploration, the variance analysis of three-stage-model must be applied to estimate analytical uncertainly and sample-collecting error.
讨论了不同转速对位移响应时变方差的影响和不同采样角频率对位移响应时变方差曲线的影响。
Influence of rotational speed on the time-dependent displacement response variance and influence of sampling frequency on the time-dependent displacement response variance curve are discussed.
协方差速度谱是基于采样数据可以排列成协方差矩阵的特征结构而设计的。
Covariance velocity spectrum is based on the fact that the sampled data can be arranged in eigen structure of covariance matrix.
传统方法是通过空域或频域采样，得到该子噪声图像，然后直接对其估计方差，它对图像信息的分布有要求。
The traditional way is to obtain the sub-image by sampling the noised image in spatial or frequency domain, then calculate its variance to replace that of the original noise.
