常見例句雙語例句In this paper, a PIV system is used to measure the scales of large scale coherent structures in the turbulent boundary layer of a flat plate.下測(cè)量平板湍流邊界層中緩沖層、對(duì)數(shù)區(qū)和外區(qū)的二維瞬時(shí)速度場(chǎng)。The article is based on coherent structures of turbulent boundary layer theory, studies the feedback control model of turbulence, and inputs control system to get the enhancement of heat transfer.本文依據(jù)湍流邊界層擬序結(jié)搆理論的基礎(chǔ)，研究湍流反餽控制模式，在湍流流場(chǎng)中輸入控制，達(dá)到強(qiáng)化傳熱的目的。Continuous wavelet auto-correlation was adopted to analyze the coherent structures of turbulent boundary layer. The result shows that coherent structures in space-time domain are of multiple scales.結(jié)果顯示，相乾結(jié)搆在時(shí)空中呈多尺度分佈，在對(duì)數(shù)區(qū)主要集中在大尺度，在緩沖區(qū)擴(kuò)散到小尺度。 返回 coherent boundary
