The computational results demonstrate that the partial root root estimator can improve the LS estimator when the design matrix is ill conditioned.

计算结果表明，在设计阵呈病态时，部分根方估计确能改善LS估计。

Root and leaf senescence closely related to MDA from the changes, as early as the leaf senescence root, root and exacerbated the trigger senescence leaf senescence.

根系和叶片衰老密切相关，从丙二醛含量的变化看，根系衰老早于叶片，根系衰老引发和加剧了叶片衰老。
