It was very dark inside: I could see nothing except a flaring gas-jet that illuminated a patch of plaster wall, throwing everything else into deeper shadow.

里面很黑，什么也看不见，只有一盏煤气灯照亮了石灰墙上的一片地方，别的全隐没在更黑的阴影中。

A new method of heat transfer augmentation with foreign gas jet impingement has recorded very high heat flux even in the case of "negative temperature difference".

异种气体射流强化传热的新方法即使在“负温差的情况下也有很高的热流量发生。”

At the region near the nozzle exit, a vibrating flow phenomenon is found, which is associated with the expansion waves and shock waves reflections inside the gas jet.

发现了在接近喷嘴出口的区域里，出现了与射流内的激波、膨胀波有关的振荡流。
