螺旋桨尾流

The test results indicates that the loss of energy in propeller slipstream is certainly reduced by adding vane wheel.

在船舶节能技术中，回收螺旋桨尾流能量来增加螺旋桨推力的导轮装置是一项具有发展前途的技术。

In the modeling of flight simulation, a six-degree-of-freedom whole non-linear equation and wind-tunnel tests data of MAV are used, the propeller twist and induced air flow on MAV are took into account.

在飞行动力学和运动学仿真中，采用了六自由度全量非线性方程，以微型飞行器的风洞吹风实验数据为依据，考虑了螺旋桨的气动扭矩、陀螺力矩和尾流对微型飞行器的影响，精确地反映了微型飞行器的实际运动特性。

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。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
