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。

By Ensemble-averaged Method, the mean field was got to show the 3D structure of flow. By Phase-locked Averaged Technique, the periodic mean field was got to reflect the periodic unsteady characteristic. The 3D structure and the periodic unsteady characteristic of the unsteady flow within the vaneless and vaned diffuser were discussed through analyzing the mean field and the periodic mean field.
