摘要
以翼型风洞为对象 ,着重介绍了变湍流度对翼型转捩因子影响的速度脉动波形采集的原理和方法 ,重点对波形采集系统用户界面的设计、定时器的应用、分页显示和连续显示等技术进行了具体介绍 。
In this paper,a principle and method of the speed pulse waveform sampling are introduced.Its object is to study an effect of the turning factor on torbulence.Test is done in the aerofoil fengwen.On design of the user interface,application of the timer and displaying way of a pape and continuity are specifically discussed.Expermental results and analysis is showed at the last.
