The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

This kind of house absolutely abandons the European and American styles in the architectural design but employs more Chinese traditional residential elements, such as the pitched roof, wall, blue tile and white wall. What's more, especially in the large spatial layout, this building advocates the closed and semi-enclosed spatial arrangement in response to the psychological characteristics of Chinese people, restraint without showiness. However, the interior life circulations without exception absorb the European lifestyle to show the life philosophy and value orientation.

这类住宅的主要特点是在建筑设计上摒弃了完全欧美化的做法，而采纳了较多中国传统住宅的元素，如坡屋顶、院墙、青瓦白墙，特别是在大的空间结构上，提倡封闭、半封闭的空间围合方式，以契合中国人内敛含蓄的心理特征，但在内部生活流线上几乎无一例外地吸收了欧式的生活方式，体现了现代都市人的生活理念和价值取向，项目配套都比较现代化，有公建、会所、游泳池等现代人所不可缺少的休闲和娱乐设施。

Flow disciplinarian of different PH indicator polymer solution and newtonianliquid in annulus line had been studied, and found speed distributing, vortex,streamline of annulus line, analytic flow field distributing in annulus and eccentricsituation and compared the results with prevenient schloar, some results different fromprevenient results are get, shch as the relation of average velocity and maxiumvelocity is not less with the viscosity exponent under the annular line, the fluid speedaffect the relation.

应用 PIV 分别研究了不同浓度的聚合物溶液以及牛顿流体在垂直环空管道中的流动规律，得到了环空管道中流体的速度分布情况、涡量情况、流线情况，分析了同心和偏心情况下环空管道内的流场分布规律，并与前人的计算结果进行了比较，得出了一些与以前不同的结论：同心情况下平均流速与最大流速的关系，并不是完全与粘性指数 n 值有关系，还与管道内流动的流动速度有关系，当速度较小时，两者的差别就小，速度大时，不符合这种规律。

Casethat begin transformation but do not become embedded in the baroclinic zone fail to complrte transformation and simply dissipate over lower sea surface temperatures.1at transformation stage,there are two features in 500mb analysis aKOPPU s surface center is located beneath concentric,closed 500mb contours and is equatorward of 5820-m contour associated with a short-wave trough to the northwest of strom bthe closed contours associated with KOPPU 24h earlier have combined with approaching 500mb trough so that KOPPU appear to be in an open wave.furthermore,streamlines associated with this short wave trough have wrapped around the circulation of KOPPU,which indicated that KOPPU has become embedded in 500mb westerlies.

台风变性分为两个阶段：变性阶段和再加强阶段；变性的开始和结束以热带气旋环流和先前存在的中纬度斜压带相互作用为基础，KOPPU嵌入先前存在的中纬度斜压带且风暴中心在冷下沉气流中，而KETSANA没有嵌入先前存在的中纬度斜压带则没完成变性只是消散在低的海平面温度(1)台风变性阶段在500hPa高度场分析中有两个重要特征：a首先风暴中心是闭合的等值线并和风暴中心西北的短波槽相关；随后闭合等值线靠近500hPa槽，因此风暴闭合中心消失，风暴位于开波中。b而且和短波槽相关流线缠绕在风暴中心，结果风暴在西风带中。
