翻译后摘要：一个高品质的流动已经建立在低湍流变几何（LTVG）8'× 8'在普林斯顿的超音速风洞。特别是，该设施正在非常低的滞止压力（- = 4 psia）下运行，在平板上产生大范围的层流，层流边界层厚约3 mm。通过马赫数为3的边界层，沿平板中心线沿着详细测量了平均剖面、振幅分布、双线相关和频谱。最初的结果是“自然”发生的不稳定性和过渡，他们正在通过测量强迫响应从一个点源（火花）。
Abstract : A high quality flow has been established in a low turbulence variable geometry (LTVG) 8' x 8' supersonic wind-tunnel at Princeton. In particular, the facility is being operated at very low stagnation pressures (- = 4 psia) giving a large region of laminar flow on a flat plate with laminar boundary layers up to approximately 3mm thick. Mean profiles, amplitude distributions, two wire correlations and spectra have been measured in detail through a Mach 3 boundary layer along the centerline of the flat plate. The initial results are for "naturally" occurring instability and transition and they are being followed by measurements of the forced response from a point source (spark) .1.
