然而在空间统计学的文献上几乎没有关于样本共变异量的研究。

Unfortunately, there is almost no research about the sample covariogram in the spatial statistical literature.

然而，这些方法都是根据样本的变异数或报酬的共变异数估算的估计值。

However, these methods are estimated according to sample variance and covariance estimators of returns.

影响丙二醛含量的QTL共检测到3个，分别位于第1和3号染色体上，对表型变异的总贡献率是13.56％。

Three QTLs affecting MDA content were detected on chromosomes 1 and 3, which could explain 13.56% of phenotypic variance.
