查询词典 swept wing

We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.

本研究针对昆虫运动的特点，研究开发了测量昆虫运动，特别是自由飞行昆虫运动的光学方法，包括：风洞中扇翅力的测量，解决高灵敏度光学测量的抗干扰问题；帧头帧尾流场测量方法，解决由CCD拍摄帧频导致的测量速度低的问题；调制相关算法，解决透明翅膀上散射光较弱问题；梳状条纹投影法，解决翅膀弓形变形测量问题，不需要以往的翅膀刚性平板或刚性条杆假设；多参数的综合测量，解决各参数间的相位匹配问题。

When the timing is off, you can get collapses on the upper wingtip as well as the lower one. I've seen cravatted wings spiraling down after doing off-timed wing-overs, so be careful and build up your wing-over height gradually. First, get the timing right in small wing-overs. When you feel confident, use more weight shift and brake input to build up your wing-overs. Keep practicing!

如果时机掌握的不好，伞可的两侧都有可能塌陷；我曾经见过由摆荡动作时机掌握的不好导致卷夹然后螺旋下坠的，所以摆荡的幅度要逐渐增加；首先要在小幅度摆荡中将各个动作的时机掌握好，练习熟练，信心增强之后在多压重心，增加刹车量将摆荡的幅度作大。

When a wing stalls the wing loses most of its downforce and drag.A single element wing will then stall, as the flow breaks up under the wing
