- In pericyclic reactions, explanation by orbital interactions give a better picture than simple discrete electron transfers. 而在周环反应中，以轨道间相互作用来解释机理要比用电子转移来描述清晰得多。
- Sclerenchyma The main supporting tissue in plants, made up of cells with heavily thickened, often lignified, walls and empty lumina. 厚壁组织：由细胞壁极度加厚，通常木质化的死细胞组成，是植物体内的一种主要支持组织，通常具有简单纹孔。

- However, the number of vascular bundles and the development of sclerenchyma are not uniform with each other. 然而,维管束的数目及厚壁组织的发育各不相同。
- Conclusions were drawn:thickness of sclerenchyma correlates with gemination percentage,and was in inverse proportion to gemination percentage. 萝卜种子发芽率的高低主要与厚壁组织层的厚度及它占种皮全厚的比例有关，且成反比。
- The leaf veins were dense, bundle sheaths had two layers, the outer layers were bigger parenchyma and the inner ones were smaller sclerenchyma. 叶脉稠密，维管束鞘两层，外层为较大型薄壁细胞，内层为较小的厚壁细胞。
- The leaf veins were dense and sheath bundles had two layers, an outer, larger parenchyma and an inner, smaller sclerenchyma. 叶脉稠密、维管束鞘2层，外层为较大薄壁细胞，内层为较小的厚壁细胞。
- Plant cell walls can be strengthened for extra support by addition of lignin (as in xylem and sclerenchyma)or extra cellulose(as in collenchyma). 这对于草本植物来说，起到了支持作用。
