求翻译：共振消声器应该安放在系统声模态的反结点。如果把消声器安放在结点处，将达不到消声效果。空滤器一般来说是声模态结点，因此不能将共振消声器安装在空滤器上。接下来便通过进气系统的声模态分析选定谐振腔和波长管的安装位置，达到最优降噪的目的。是什么意思？

Resonance muffler sound system should be placed in the anti-modal nodes. If the muffler placed in the junction, the effect will be less than muffler. Air filter is generally sound modal nodes, so the resonance can not be installed in the muffler on the air filter. The next intake will be through the

Resonance silencer model sound system should be sited on the anti-nodes. If the silencer, sited on the nodes will not reach the effect of sound. air cleaner was generally a sound model nodes, therefore you cannot resonance silencer in air cleaner. Next to the air inlet is through the sound system mo
