查询词典 variance analysis

Second, this dissertation analysises the performance of TA cyclospectrum estimation, and derives the averaged cyclic periodogram which can make the variance to be reduced.

第二，本文分析了TA(Time Aliasing，时间重叠)循环谱估计方法的性能，并推导了使方差得以减小的平均循环周期图方法。

A novel algorithm for InSAR SLC coregistration is proposed. The averaged periodogram is used as evaluation function of registration in the new algorithm and the estimation variance of evaluation function is reduced by separating the data into numbers of subsections and averaging them, thus the accuracy and reliability of registration is improved.

提出了一种新的干涉合成孔径雷达复图像配准算法，新算法使用干涉相位图的平均周期图作为配准的评价测度函数，采用数据分段求平均的方法降低了评价函数的估计方差，从而提高了配准的精度与可靠性。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes.

而在这种假设的前提下，即使系统各参数值在发育过程中受到随机的扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统也会产生出某个有限的、离散的表型[11]子集。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes. Thus the realm of possible forms is a property of the internal structure of the system.

而在这种假设的前提下，即使系统各参数值受到发育过程中的随机扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统会产生出某个某个有限的、离散的表型[11]子集，因此，生物可能形态的王国，其疆域从属于生命系统的内在结构。

如果你想为了你的家而改变居民区的话，你不得不先争得这个城市的同意。

With the increase of irradiation dose,the rates of slanting and creeping types of plant increased.80Gy irradiation was fit for leaves to keep green in winter than other applied doses.Phenotypic variation were observed in V_1 generation,including variance in height,average node length,diameter/height,leaf shape index,leaf area,blasted tips,biforked tips and phyllotaxis.

随着辐照剂量的增大，倾斜和匍匐生长的植株比例呈增加趋势。80 Gy处理有利于使植株的叶色在冬季仍保持绿色。V1代筛选出株高、平均节长、粗/长、叶形指数、叶面积以及枝条枯梢、分叉、叶序变化等性状的变异体。
