在近几年的研究工作中，我们发现用多数小喷口代替排气的大喷口可使其所产生的噪声中对人干扰的部分大大减少，并求得定量关系。
In recent years, investigations show that the hazardous noise will be greatly reduced by replacing the large exhaust nozzle with a number of small nozzles, and quantitative relations were found.
在瓣形喷口中，排气被分开，流过各瓣和一个小的中央喷管。
In the lobe-type nozzle, the exhaust gases are divided to flow through the lobes and a small central nozzle.
