The acoustical behavior of a motorcycle exhaust muffler was simulated with the boundary element method. 摘要用边界元方法计算了某一摩托车排气消声器的消声性能。
The structure and the aerodynamics performance of marine exhaust muffler is one of the important aspects when the diesel engine is installed on the ship. 船用排气消声器的结构和气动性能是柴油机装船技术研究的一个重要组成部分。
