internal porosity

基本解释

Can increase the internal porosity of the friction material thus helping to reduce noise.
能提高摩擦材料内部的孔隙率从而帮助减少噪音。
It is shown that background porosity reduces internal pressure fluctuation and this effect can be predicted accurately by using the governing differential equation deduced in this paper.
研究结果表明本文推导的方程能准确的预测背景孔隙对风致内压响应的影响，能为工程抗风设计提供有效的理论依据。
Hence, when the slab is subjected to the liquid core pre-rolling, it will be possible to obtain a refinement of the internal structure by reducing the central porosity as well as the segregation.
因此，当板坯经历液芯预轧制的时候，将可能会通过减少中心多孔性和分离来获得内部结构的精制。
