使用三维数值计算方法预测内燃机排气消声器的声学性能和阻力特性。
The 3-d numerical methods are used to predict the acoustic attenuation performance and flow resistance characteristics of internal combustion engine exhaust silencers.
内燃机排气消声器的实际消声性能既与消声器本身结构有关，又与排气噪声源性质有关。
The performance of an exhaust muffler of internal combustion engine is related not only to the construction of itself, but also to the characters of the exhaust noise source.
我只是按照自己的方式生活。但是后来我遇到了你妈，然后你就跟着来了。所以现在我在一家（内燃机）消声器店工作。
I just figured my life would come together on its own. But then I met your mom, and you came along. So now i work at the shop.
