分层

It has thus been demonstrated that a tiered approach at all three steps can be helpful to optimize the use of the available resources; if relatively crude tools –designed to provide a "worst case" estimate –do not suggest a toxicologically significant exposure( or a relevant deficit of a particular nutrient) it may not be necessary to use more sophisticated tools.

已经证明，在所有的三个步骤中一种分层的方法能够有效优化可用资源：如果一种相对粗糙的方法――设计用来对最坏的情况进行评估――没有显示有毒理学意义的暴露（或者某种特定营养的不足）――那就不需要再使用更精确的方法。

During the wall thickening, the number of Golgi bodies increased apparently and cytoplasm was filled with Golgi vesicles. Polylamellate structure of the secondary wall appeard, Along with the further development of tracheary elements, the nucleous disappeared and organelles were decreased, while cortical microtubules were arranged neatly against the inner side of plasmalemma.

初生壁与质膜之间有间隔较规律的次生壁突起；中期，线粒体和高尔基体的数量明显增加，细胞质中几乎充满高尔基体及其囊泡，次生壁中微纤丝已成有序排列；晚期，细胞核消失，导管中央形成空腔，细胞器迅速减少，仅观察到少量高尔基体和线粒体，有大量周质微管沿细胞长轴分布，且在次生壁的周围有大量小泡附着，次生壁的分层结构清晰可见。
