重新检查薄剪切流中热湍流的各种研究，以评估标量脉动场的时间尺度与速度脉动场的时间尺度之比。在考虑的所有情况下，发现该比率几乎是均匀的，其值接近0.5。
Various studies of thermal turbulence in thin shear flows are re‐examined in order to evaluate the ratio of the time scale of the scalar‐fluctuation field to that of the velocity‐fluctuation field. In all cases considered it is found that the ratio is nearly uniform with a value close to 0.5.
