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。

It is found that the former provide more uneven circular stress state than the latter after comparing the circular stresses both of intrados and extrados,which extrados stress is large and intrados stress is small.That is confirmed by the results of experiment that the practical burst pressure...

Methods From May 2007 to Oct 2007, 13 cases of soft foot and ankle tissue coloboma were repaired or reconstructed with this flap. The perforator branch was detected and earmarked by Doppler ultrasound. The flap axis was designed as the connection of internal condyle of tibia and the middle point between inner malleolus and achilles tendon based on anatomy. The pivot was designed in the point which perforator branch perforate the deep fascia. The flap dissociation was performed upon the deep fascia and the flap thickness can be modified during the operation.
