摘　　要：表面声强测量是现代声强测量技术研究的一个重要分支。本文探讨了采用一种新的表面声强测量法，这一方法涉及到点辐射阻抗的色散关系。对Ｓ１１１０型柴油机表面噪声辐射情况进行试验研究，取得了成功，其结果对降低噪声有指导意义。Surface acoustic intensity technique is an important research branch on acoustic intensity measurements. In this paper a new surface acoustic intensity measurement method, which concerns the chromatic dispersion relationship between point radiation resistance and reactance, was used on Model S1110 Diesel Engine to determine noise radiating from the engine surface. This new method has been successfully used to test the surface noise, and given the useful results for guiding the engines noise control work.
