The duodenal juice mainly consists of the bile acid, which is a sort of lipophilic steroid and may result in direct injuries of mucosal epithelial cells and their tight junctions. Some researches have showed that the bile acid directly damaged the chemical environment of mucosa surface and played a synergistical role in gastric mucosal lesions along with gastric acid and H.

十二指肠反流液中主要成分为胆汁酸，胆汁酸是十二指肠反流液中造成黏膜损伤的主要成分，为一种亲脂性类固醇，直接破坏黏膜上皮细胞以及细胞间的紧密连接，同时还对腔内及黏膜表面的化学环境造成直接的影响，增强胃酸、H。

Conclusion］ Somatostain intraarticular injection can relieve the inflammation and increase the SOD content of synovia of osteoarthritis.

结论］关节腔内注射生长抑素可使关节软骨损伤减轻，滑膜炎症得到控制，减轻关节液中SOD含量增加。

The sac structure projected through the pollen aperture possesses the typical nature of transfer cell, i. e complex lybrinthian wall ingrowth and abundant mitochondria, RER, dicotysomes and ribosomes under the wall. Its outer surface is closely related to the tapetal protoplast. The accumulation of storaged material in pollen start at the area near the apertures. Above restults indicate the pollen apertures may be the"door"from where nutrition flows into pollen in P. hortorum.

绒毡层物质向花粉粒的短途运输明显的表现在花粉的萌发孔区，一方面形成向外突起的囊腔，另一方面在这里具有发达的壁迷宫，而且迷宫下具丰富的线粒体，RER和高尔基体等细胞器，此外花粉内贮藏物的大量积累首先从萌发孔附近开始以及萌发孔处与绒毡层有紧密接触都说明天竺葵花粉萌发孔可能是物质进入花粉的&门户&。

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。
