In high temperature sintering , on the one hand, big across hole is formed by gas closed in porosity that passes through molten glass phase, and mechanical properties is declined.
高温烧结时，一方面，熔化的玻璃相被封闭气孔中的气体穿过形成贯穿大孔洞，削弱高温烧结时的力学性能；
2
The porosity and thickness affect markedly on the sound absorption property of Al-Si closed-cell aluminum foam: the sound absorption coefficient increases along with increasing porosity;
铝硅闭孔泡沫铝的孔隙率和厚度对其吸声性能影响显著：吸声系数随孔隙率增加而增加；
3
The thermal conductivity coefficient of closed-cell pure aluminum foam was measured as a function of porosity and cell size.
