本篇报告的内容是我们从1974年以来所做的工作.主要介绍有关喷注噪声及其控制方面的紧密与实际相结合的基础理论研究工作.在整个工作中我们深深体会到,从广泛实践中抽象出来的基础理论研究的重要性及其对实践的指导作用. 一、喷注的湍流噪声[1] 随着工业的发展,气流喷注的出现
The content of this report is what we have done since 1974. It mainly introduces the basic theoretical research on the combination of close injection of noise and its control with the actual control.In the whole work we deeply understand that from the broad The importance of basic theoretical research abstracted in practice and its guiding role in practice I. Turbulent noise of jetting [1] With the development of industry, the emergence of air jetting
