For a jet impinging onto a concave plate, the OASPL of the far-fieldnoise is quite sensitive to position variations of the nozzle.
对于冲击面为凹面的冲击射流，远场噪声总声压级对喷嘴位置改变非常敏感。

This study focused on analysis of pressure fluctuation on the body surface, prediction of exterior far-fieldnoise and interior noise and the road tests.
本文的研究重点包括车身表面脉动压力的求解和分析、车外远场噪声和车内噪声的预估以及实车道路试验研究。
