能用相机拍出来激波来？实验室拍摄激波需要纹影仪呢？对不对？

也凑个热闹！

看个动态的。

图中所能见到的激波景象的确是摄影机摄到的？不过我还是很喜欢，因为图中的F-14、B-1是我所喜欢的。因为它们代表了美国人在战斗机和轰炸机上运用变后掠机

不错！！

空气动力学上激波是看不到，而交通流动力学上的交通激波是看的到滴！

讚唷

个人觉得很像高速的马赫锥，但是理论上应该是看不到啊

At first I had the same opinion as yours,later I discussed with others and researched some materials then I got the conclusion:
the pressure after the shock wave is much higher than that before shock wave.High pressure decreases the dew point(露点) of vapor(atmosphere consists of oxygen,nitrogen,vapor etc.).So we can see the areoplane surrounded by fog.Do you agree to the above arguments?

需要梦想

这种景象好像不会持续的吧，是不是只在突破音障的事后能看到啊，没见过哪个超音速飞行的飞机一直都带着这么个东东！

确实是由于激波而变化引起了水蒸气的相变
