Improve the machine's lift-drag ratio, fuel savings; breaking the ground effect aircraft in ground effect can limit the area of flight, like an airplane ascend to high altitude flight safety, a real combination of aircraft and ships, and greatly expand its application and scope of use.袁昌华...
The Use of the 300 Microsecond 1064nm Nd:YAG Laser in the Treatment of Keloids BACKGROUND: Keloids can be quite resistant to conventional methods of treatment. A wide range of treatment modalities exists, often with suboptimal results... A Rossi,R Lu,MK Frey,... - 《Journal of Drugs in...

The marker frame data revealed that the insects strongly tilted their backs towards the light source (Fig.3). Examining the dorsal axis projected onto the ground-plane showed the body tilt strongly matched the direction of the light with a 1:1 ratio in all four species (Fig.3a). Insects w...
The correction factor relative to ideal momentum jet theory is greater than for the hovering ground effect, forward flight ground effect, or wind tunnel wall interference problems at comparable distances. The flow pattern that develops in the presence of floor and wall interactions in hovering or ...
The onboard ground test is mainly used to further assess the characteristics of the flight control law in the real environment of aircraft, such as the interface with other relevant airborne systems and the stability after closure through the aircraft structural mode, so as to further determine th...
In the sustainable development of the global economy, the importance of large cities and urban agglomerations has become more and more prominent. Nevertheless, the traffic congestion in these areas is getting worse and worse. The marginal effect of increasing ground traffic capacity on alleviating traf...
