Compared to the respectively alone stress, cold + 5 km hypoxia (4 hours/day, continuation for 2 days) and restraint + 5 km hypoxia combinated stresses significantly inhibited body weight gain of rats, and the five stresses also markedly decreased hepatic glycogen contents, and increased plasma glucagon levels. 2. Effect of continual hypoxia on the level of insulin secretion Compared to the sea level normoxia control group, simulated continual 2 km hypoxia for 1-25 days (1, 2, 5, 10,15 and 25 days) did not significantly influence rats body weight, food intake and plasma insulin level.

连续性低氧对胰岛素分泌水平的影响与海平面常氧对照组相比，模拟2km连续低氧1-25天(1、2、5、10、15和25天)没有明显影响大鼠体重变化、摄食量和血浆胰岛素水平，但在低氧第2天显著升高肝糖原含量和血糖水平，在第10天明显升高血浆胰高血糖素水平，在第1天血浆皮质酮水平显著升高，在第1和第2天瘦素水平明显上升，然而在第5天瘦素水平显著下降。

Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。
