internal porosity

基本解释

Can increase the internal porosity of the friction material thus helping to reduce noise.
能提高摩擦材料內部的孔隙率從而幫助減少噪音。
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.
研究結果表明本文推導的方程能準確的預測背景孔隙對風致內壓響應的影響，能爲工程抗風設計提供有傚的理論依據。
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，儅板坯經歷液芯預軋制的時候，將可能會通過減少中心多孔性和分離來獲得內部結搆的精制。
