Analysis of variances When a cost variance occurs, the person in charge should examine the variance to determine the factors that may have caused it.

差异分析当成本发生变化时，负责成本的人须查验此差异变化，并找出导致该变化的因素。

Secondly this dissertation made the statistical analysis of brittle ice load, and results showed that there was a greater variance of ice load during slow ice speed movement and a smaller variance of ice load during fast ice speed movement.

其次对冰脆性破坏时的荷载进行了统计，结果显示当冰速较慢时荷载的变化较大，而当冰速较快时荷载的变化较小。

With regard to the estimation of the variance components, many statisticians proposed a number of approaches, such as the Analysis of Variance Estimator, Maximum Likelihood Estimator, Restricted MLE, and the Minimum Norm Quadratic Unbiased Estimator, etc.

关于方差分量的估计统计学家们提出了许多方法，如方差分析估计，极大似然估计，限制极大似然估计，最小范数二次无偏估计等。

Another advantage of these improved methods is the flexibility of rendering multiple volume data sets. There is detailed analysis and experimental proof of this flexibility. Besides, since the sample variance can reflect sample value distribution, an enhancement algorithm based on variance statistic is proposed.

另外，本文根据样本距统计量能够反映样本数据值分布的特点，提出基于方差统计的增强算法，绘制结果能够突出显示局部方差统计值较大，即结构分布较复杂的区域。

The SPSS program was performed to test normality of the dataset, variance homogeneity between the groups, coefficients of variation and analysis of variance.

The 54 accessions were classified into five major groups:Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Genetic differentiation between and within eight eco-geographical groups of C.dactylon was estimated by Shannon's diversity index, which showed that 63.81% genetic variance existed within group, and 36.19 % genetic variance was among groups, indicating rather large genetic distances among those germplasm, and there was a correlation between genetic differentiation and eco-geographical habits among the groups.

聚类分析结果表明，52份材料可聚为5类；基于Shannon多样性指数估算了8个狗牙根生态地理类群内和类群间的遗传分化，类群内的遗传变异占总变异的63.81%，类群间的遗传变异占总变异的36.19%，表明这些抗源材料遗传差异较大，各生态地理类群间的遗传分化与其所处的生态地理环境具有一定的相关性。

After studying analysis of variance on single factor and double factor,this paper reveals that if the difference between levels of the primes exist noteworthily is mainly depended on the sum of its experiment effects or variance of experiment effects and stochastic difference.

0引言 在试验设计时设置重复试验，能够估计试验误差；重复试验次数越多试验误差越低，试验精确度越高。一般认为，适宜重复次数应保证使误差项自由度至少为12，否则F检验或t检验的临界值上升很快，难以呈现显著性川。

Methods We meased the abdominl subcutanous fatty thick (30 case ,4 point,every point 9 times) by 5 MHz urltrosonic wave and analysised the reappearance by paired ttest and analysis of variance and the distribution of coefficient of variance.
