利用2005年7月盘锦芦苇湿地生长旺季的小气候梯度系统30 min观测资料和开放式涡动相关系统10Hz原始观测资料，比较并分析了廓线法、波文比能量平衡法与涡动相关法计算的芦苇湿地生态系统水热通量。

The hydrodynamic performance and the calculation of induced velocity along flow on the constant point after foil shows that if the effects of tip vortex and decay of vortex panel strength be considered, the accuracy of calculation can be increased. Velocity peak value in propeller wake current and distribution of induced velocity after three-dimensional short foil else can be calculated accurately.

通过对三维短翼的水动力性能和翼后给定点沿流向的诱导速度计算表明：采用考虑翼梢涡影响和涡的衰减影响的计算模型，可以提高三维短翼的水动力性能计算精度；可以准确地计算出螺旋桨尾流场的速度峰值；可以较好地计算出三维短翼翼后的诱导速度分布。

Corresponding to simulation results, middle flow shows more regular because vortex separation from upstream tube bundles suppress the vortex generation in downstream.

由于多个拟序的涡结构在下游不断的相互作用使得尾迹中的涡结构越来越混乱。
