- 摘要：
- In order to study the effect of high temperature on the absorb properties of fibrous metal materials, the effect density of air in the fibrous metal porous material is obtained on condition that the propagation of a sound wave along the skin of very thin fibrous material and the boundaries between fibers are assumed as equilateral polygon; Secondly the idea of thermal viscous layer is obtained from the expand of the theory of velocity viscous layer, and the bulk modules is derived with the theory of heating transfer and equation of state of gas and the effect of thermal is considered. On this basis, the law of thermal affect on absorbing property is analyzed, finally, the proposed theory is verified by the experiments.
