The numerical calculation results show that the favorable pressure gradients have apparent laminarflowcontrol property, and the unfavorable pressure gradients have a strong unstable influence.
数值计算结果表明，顺压梯度有明显的延缓转捩作用，逆压梯度有较强的不稳定作用。

Looking at that in the lab, it becomes a function of airfoil shape, and also of the flowcontrol technologies you use to enhance the laminarflow with conformal trailing edge surfaces.
实验室的研究表明，它已经成了机翼的一项功能，也是通过适形机翼后缘表面来增强层流的流控制技术的功能。
