摘要
考虑纤维间的黏结作用,引入等效容重的表述,得到改进的纤维性吸声材料的唯象模型.实例分析表明,由改进模型计算的理论值与测量数据吻合更好.
Based on a consideration of the glue effect and the introduction of the definition of equivalent volume mass, the improvement equivalent formulations were proposed. An experimental examination was also discussed. Theoretical results agree better with the experimental data.
