对椭圆射流的细致研究拓展了人们对射流问题的认识，尤其是射流中相干结构的认识。

A detail study of elliptic jets facilitates a better understanding of the wider class of jets were the curvature of the coherent structure changes around the perimeter.

把实际工程现象抽象为大空间强热源诱导含尘浮射流问题，在相似理论指导下建立了实验模型。

The HHSIDBJ(High Heat Source Induced Dusting Boyount Jet) was abstracted from an actual engineering situation and the testing model was designed under the similar theory.

解决了长期以来无法拍摄到高温、高速、强火焰光的火箭射流流场图像的问题。

So the problem of taking the picture of real rocket jet with high temperature, high velocity and strong flame was solved.
