1·Special attention should be given to the decrease of the additive variance of yield trait, and this will most possibly make genetic background narrow.

值得注意的是，产量性状的加性方差有降低的趋势，遗传基础可能变窄。

2·The additive genetic variance of the same character, estimated from the covariance of half sibs, was 0. 9602.

从半同胞协方差估计出来的，同一性状的加性遗传方差为0.9602。

3·The variance component analysis revealed that the ratios of additive genetic variance to phenotypic variance of the majority of economic traits were high.

进一步的方差组分估计表明，主要经济性状的加性遗传方差较大。

4·In order to improve the robustness of this method, two-factor analysis of variance and additive model is proposed to reduce the impact of style information on face observed feature.

为了提高该方法的鲁棒性，通过两因子方差分析与加性模型分离人脸内因子与外因子，降低风格信息对人脸观察特征的影响。

5·We can also obtain M2 and spatial variance at other axial positions with the help of additive lenses.

借助参数已知的附加透镜也能得到光束的M2和任意轴向位置的光束横向尺寸。
