Telomeres, short tandem repeat sequences at the ends of eukaryotic linear chromo somes, function to stabilize chromosomes.

端粒是真核细胞染色体末端的重复序列，对维持染色体的稳定性具有重要作用。

The reticulated vessel which has large cavity has thicker wall due to more elastic fibers and more smooth muscles and its endothelium is cuboidal epithelium which has rotundity karyons. But the reticulated vessel which has small cavity has thinner wall due to less elastic fibers and less smooth muscles and its endothelial cells are flat epithelial cells which have long-shuttle-shaped karyons. In some regions, the ducts are very small in diameter and thin of wall, and they become blood sinus in the end.

管腔大者，管壁厚，弹性纤维、平滑肌纤维多，内膜靠腔面内皮细胞多成立方状，细胞核端位近圆形；管腔小者，管壁薄，弹性纤维、平滑肌纤维少，内皮细胞扁平、排列稀疏，胞核长梭形；一些区域管径极小，管壁极薄，成为开放的血窦，只允许一个血细胞通过。

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。
