Objective To investigate the method of repairing defects of nasal tip with a reversal flow axial postauricular island flaps supplied by superficial temporal artery to enhance the effect of aesthetics therapy.

目的：探讨应用颞浅动脉供血的反流轴型耳后岛状皮瓣转移修复鼻尖缺损的手术方法，以提高鼻缺损畸形的美学修复效果。

a reversal flow axial postauricular flap has a similar color to the nose and a hidden donor site, It is a good selection for reconstruction of defects of nasal tip.

反流轴型耳后岛状皮瓣修复鼻尖缺损，色泽形态良好，供区皮瓣组织量充足且隐蔽，是修复鼻尖缺损的好方法。

Flow is directed radially inward toward the nozzle axis .

流是针对外来的径向对喷嘴轴。

A non-singular single integral mathematical model is adopted to calculate the external intermittent and alternative longitudinal magnetic field acquired by single axisymmetrical and cylindrical hollow coil t which is coaxial to electrode and excitated by a revisable pulsed current of square wave t in austenitic stainless steel GTA welding.

针对奥氏体不锈钢外加纵向磁场的气体保护钨极电弧焊接时，与电极同轴的单个轴对称空心圆柱线圈在双向脉冲矩形励磁电流作用下产生的间歇交变纵向磁场，采用无暇点单积分磁场的数学模型，对＊TAW焊接外加间歇交变纵向磁场进行了数值计算，该方法具有模型简单、计算速度快和精度高等优点并讨论了该间隙交变纵向磁场的分布、磁场的均匀性及其纵向分量与径向分量的比率等规律及其对焊接行为的影响，认为横磁分量将削弱GTAW外加纵向磁场的有利作用，影响磁控电弧的焊接质量

And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

Objective To evaluate and explore the reconstruction technique of straddling region reversal flow axial composite auricular island flap with blood-supply from supraorbital artery or supratrochlear artery for repairing large alar defects .

目的：探讨以眶上动脉或滑车上动脉为供血源的跨区反流轴型耳廓复合组织岛状瓣，修复大面积鼻翼缺损的临床应用特点。

The patients were treated with reversal flow axial composite auricular island flap based on supraorbital artery or supratrochlear artery.results6 cases were treated with the technique, only one case underwent epidermal blisterand, and the partial skin flap necrosis, the necrosis area of flap was 1.0cm×2.0cm, 5 cases were successfully repaired with satisfactory.conclusionthe island flap could be an ideal way for the one stage reconstruction of large alar defects, which is recommended to be widely used.

结果：在临床上将该方法应用于6例病人，除1例出现表皮水疱，后皮瓣部分坏死，面积约1.0 cm×2.0，其余5例取得满意的临床效果。结论：反流轴型的耳廓复合组织瓣能ⅰ期修复大面积鼻翼缺损，是一项极具推广的修复手段。

objectiveto evaluate and explore the reconstruction technique of straddling region reversal flow axial composite auricular island flap with blood-supply from supraorbital artery or supratrochlear artery for repairing large alar defects.methodsfrom may of 2004 to macth of 2008, 6 patients with the lager alar defects were studied.

目的：探讨以眶上动脉或滑车上动脉为供血源的跨区反流轴型耳廓复合组织岛状瓣，修复大面积鼻翼缺损的临床应用特点。方法：从2004年5月～2008年3月间，我科选用游离眶上动脉或滑车上动脉与颞浅动脉额支的吻合支为供血源所营养耳廓复合组织瓣，经皮下隧道转移至鼻翼缺损区，ⅰ期修复6例大面积的鼻翼缺损的患者。

While with the Coriolis force omitted, the flow in the cavity is under the influence of centrifugal buoyancy force, which can develop from stable to unstable as this force enhances. The centrifugal buoyancy force could lead to flow unstably.

哥氏力垂直于〓与〓构成的平面，对径向速度导致切向作用力，对切向速度导致径向作用力，在该力的作用下盘腔内轴向通流诱导的旋涡被压扁，尽管涡强有所增加，但是盘面的平均换热基本减弱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
