    The characteristics of jet was described including the velocities at every point over the jet cross-section, the shape of the jet and then the generation of jet noise .Some experimental formulae about jet sound power and jet noise pressure which are contributed by the Noise Control Laboratory of The Pennsylvania State University are recommended. Some research works of this Laboratory had achieved huge work with various jet fluids, different circumferential medium and different jet velocities .Numerous data and curves had been obtained and these formulae were then performed statistically.The effects of the velocities of jet and the diameters of the nozzles on the generation of noise has been investigated. Some suggestions on the noise reduction have been proposed here. It describes the behaviour of comby nozzle separating fluid and the effect of multi-nozzle-suppression. It also introduces an absorptive ring for the noise reduction.

    本文首先分析了喷流的特性从流速在截面上的分布,喷流的形状,讲到喷流噪声的发生。 接着推荐美国宾州大学噪声控制研究室关于喷流声功率与声压级的经验公式。他们曾通过对于不同密度的周围介质,不同的射流质量,不同的喷流速度作了不少次试验,获得了不少数据和曲线,归纳出这几个公式。这些公式在实践中证明基本上是符合实际的。 本文在分析这些公式的基础上,分析流速和喷咀直径对发生噪声的影响,提出有些情况下可采取的降低噪声的措施。阐述了蜂窝状喷咀分流降噪的机理,介绍了分流喷咀的实践效果以及在宾州大学试验采用吸声套圈的效果。
