速度脉动 meaning in Chinese
velocity fluctuation
velocity pulsation
Examples
- The detailed experimental investigation of the distribution and evolution of the mean velocity profile were executed . the signal of instantaneous velocity , the energy spectra of velocity and wave characteristics in the boundary layer have been analyzed
对局部加热的水平平板下表面边界层内的时均速度的演化规律进行了详细的测量，同时对速度脉动信号以及速度能谱进行了分析，并对边界层内的波动特性进行了研究。 - The fluctuation of the fibers " velocity and angular velocity was considered , too , and the influence of flow velocity on them was obvious : the fluctuation intensity of fibers " velocity on flow direction was larger than that on cross direction , while it was opposite for the fluctuation intensity of fibers " angular velocity
同时又考虑了纤维速度和角速度的脉动，二者都充分体现了流体速度脉动的影响，且纤维速度的脉动在流向上的强度大于横向，而其角速度的脉动在流向上的强度小于横向。 - Artificial periodic disturbances are introduced to the outer field of turbulent boundary layer in an closed - circuit open water channel . statistical method is employed for analyzing the velocity - fluctuation - time - series . the effect of the disturbance to turbulent structure in boundary layer is studied
在开口式循环水槽底部湍流边界层外区中引入周期性扰动，对湍流场的速度脉动时间序列信号进行了统计分析，研究了湍流边界层中周期性人工扰动对湍流结构的影响，结果表明高频扰动的湍流中she - leveque简称sl湍流层次相似律成立。 - Abstract : 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
