柴油機(jī)表面噪聲源識(shí)別技術(shù)研究 - Abstract : in the paper , based on the problem that strong reactive background noise can bring about a big measurement error when sound power is measured in a narrow room , such as power room in a diesel locomotive , it is analyzed theoretically that sound power is measured and carried out by using sound intensity probe hood , and sound power of diesel engine surface noise is measured in a power room
文摘:在狹小空間如內(nèi)燃機(jī)車動(dòng)力室的條件下，測量柴油機(jī)表面噪聲聲功率時(shí)，動(dòng)力室內(nèi)抗性背景聲很強(qiáng)引起較大的測量誤差，從理論上分析了采用聲強(qiáng)探頭罩進(jìn)行聲功率測量的可行性，并進(jìn)行了內(nèi)燃機(jī)車柴油機(jī)表面噪聲的聲功率測量。 - It's difficult to find surface noise in a sentence. 用surface noise造句挺難的
