In heterogeneous anisotropic materials the thermal diffusivity cannot be described by a single number . 在各向異性的非均質(zhì)物質(zhì)中,熱擴散率不可能用一個簡單數(shù)字來表達。
Limiting the extraction of great amount of heat from the underground even more is the low thermal conductivity and low thermal diffusivity of rocks . 由于巖石的熱導(dǎo)率和熱擴散率都比較低,更加限制了地下熱能的大量抽取。
