影流

网友们纷纷表示了对该片的赞赏之情，很多人都像刘啸宇的父母一样在观影时流下热泪。

Many Web users subsequently said they greatly appreciated the film and most of them said they cried right along with Liu ` s parents .

应用蒸汽屏、纹影和油流技术拍摄了空间和表面流型照片。

And photos of flow off body and on lee surface have been taken .

研究了横向喷流引起流动分离的干扰流场特性，利用表面压力分布测量和纹影、油流等试验方法研究了此类流场的细节结构，给出了干扰流场的结构分析图。

The interference flow field characteristic of flow separation induced by transverse jet was investigated . The detail structure of this kind of flow field was studied by pressure measurement , schlieren photo and oil visualization , and the sketches of the interference flow field structure were drawn .

实验马赫数为1.10、1.53、2.53、3.01和4.01，攻角范围5°～25°。借助于蒸汽屏、纹影和油流技术拍摄了脱体和表面流型照片。

By using of laser vapor-screen , schlieren and oil-flow techniques , the test was carried out at Mach numbers of 1.10 , 1.53 , 2.53 , 3.01 and 4.01 for angles of attack from 5 ° through 25 ° Photos of flow off-body and on Iee-surface have been taken .
