1·Early growth wood is relatively porous.
生长早期的木材是相对多孔的。
2·Late growth wood is denser, less porous.
晚生木材密度大,没有那么多孔。
3·Impacts on porous bodies generate less debris, so more energy goes into producing heat.
撞击多孔体产生的碎片较少,因此产生热量的能量更多。
4·A recent discovery that asteroids are highly porous makes Rubin's hypothesis more plausible.
最近的一项发现表明小行星非常多孔,这使得鲁宾的假设更加可信。
5·By contrast, dry soils are sandy and porous, their coarse textures permitting water to drain rapidly.
相比之下,干燥的土壤是沙质和多孔的,其粗糙的质地允许了水分的迅速流失。
