柏属植物

The chemical constituents of Chinese Herbal Medicine Selaginella sinensis, Senecio kaschkarovii and the root bark of Ailanthus altissima were studied in this thesis.

The conducting tissue structure of transverse and longitudinal sections was observed on leaves of Podocarpus and Nageia.

该研究对罗汉松属和竹柏属植物叶横切面和纵切面输导组织结构进行观察。

Considering other differences that in leaves of Podocarpus there are three resin ducts under vascular bundle of midrib, mesophyll cells are differentiated into palisade tissue and sponge tissue; in leaves of Nageia, there is only one resin duct under vascular bundle in each vein and no obvious differentiation in mesophyll cells, palisade tissue can be found on both sides, and sclereids can also be found in mesophyll tissue.

结合罗汉松属植物主脉维管束下面有3个树脂道，叶肉分化为栅栏组织和海绵组织，而竹柏属植物每个叶脉维管束下面有1个树脂道，叶肉分化不明显，两面都有栅栏组织，叶肉中还具有大量石细胞等特征，认为罗汉松属和竹柏属在叶脉、叶形态和结构方面存在明显差异，2个属分开是比较合理的。

Part I Selaginella sinensis Plant characteristic and pharmacological activity of Selaginella and Selaginella sinensis are introduced.

综述了卷柏属植物化学成分的研究进展，详细总结了主要化学成分黄酮类化合物的研究进展。

Polystely Having many steles, as in the stems of some Selaginella species.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
