对多层扩容减压消音器的设计改进

An improved design for multilayer silencers with expanded capacity and reduced tension

探讨了高中压蒸汽排汽放空口噪音产生机理，对多层扩容减压消音器做了改进设计。

According to how great intensity of sound is produced through discharge of high or middletension steam,an improved design for multilayer silencers with expanded capacity and reduced tension has been satisfactorily carried out.
