The measurement results show that there is really a distortional boundarylayer displacement surface on the ground board, and it fully differs from natural growing boundary layer on the ground board.
测量结果表明：在地板上确实存在一个畸变的附面层位移面，它与自然增长的地板附面层截然不同。

Meanwhile, the stream turbulence effects on the measurement are studied. Finally, the problems which must be researched further are presented for indicating boundary-layer transition.
本文同时还研究了气流湍流度对测量方法的影响，最后提出转捩测量技术尚需进一步研讨的问题。

With boundary-layer modification, virtual calibration, color-spectrum measurement, the mixed result was proved to be fairly good.
