利用流体瞬变流和水声学理论分析了自激振荡气蚀射流喷管内的流动规律，建立了喷管内水声学特性的特征方程，并给出了数值解。

In conclusion, our studies indicated that, by reducing the concentration of corticoid, increasing the GH concentration, dietary glutamine could maintain the N balance in the body, induce the intestinal glutamine extraction from blood, maintain the glutamine store in muscle tissue and plasma, decrease the glutamine flux from muscle tissue and protein catabolism. As the key fuel of intestinal mucosa and lymphocytes, exogenous glutamine maintained the intestinal structure, function and the CD4〓/CD8〓 ratio. In addition, glutamine normalized the SIgA containing cells'quantity and distribution through stimulating the IL-6 gene expression.

综合分析本研究的试验结果，我们认为，日粮中的外源性Gln可通过降低断奶应激后血清中皮质醇浓度，升高生长激素的浓度维持体内N的平衡，降低肠粘膜细胞从血浆中摄取的Gln，减少骨骼肌蛋白质的分解，维持骨骼肌和血浆中Gln浓度，维持淋巴细胞亚群中CD4〓/CD8〓比例；提供肠粘膜细胞能源和代谢的前体，维持肠粘膜正常的屏障结构和功能，通过刺激IL-6的表达，维持肠粘膜中SIgA分泌细胞的数量和肠道的局部免疫功能，并最终提高断奶仔猪的生产性能和抗病能力。

These results suggested that adrenal corticoids play an important role in maintaining sympathetic tone on the central cardiovascular regulation and basal BP, and that the enhancement of cardiovascular activities produced by adrenal corticoids may be one of the important causes in the incidence of stress-induced hypertension.
