When the sample size is great, QIF approach shows that the selection of working correlation is same to the selection of unbiased estimating equation.
当样本量较大时，QIF方法表明工作相关阵的选择等价于无偏估计方程的选择。
The selection of chromatographic column, flow rate of carrier gas, column temperature, solvent, sample size and the column ratio of sample and solvent were experimented.
并对色谱柱、载气流速、柱温溶剂、进样量等色谱条件的选择，以及试样与溶剂的体积比的选择进行了实验。
Reagent selection, control style and temperature chosen, along with sample size is investigated for a range of materials with different structures and delivery mechanisms – caplets, gel caps etc.
试剂的选择，控制方式和温度选择，以及样本大小的研究是根据一系列不同结构和输送装置的材料，如：粒，胶帽等。
No baseline data were found to be related to the prognosis due to a small sample size and selection bias.
因小样本及选择偏倚，无基线资料与预后相关。
