In heterogeneous anisotropic materials the thermal diffusivity cannot be described by a single number . 在各向异性的非均质物质中,热扩散率不可能用一个简单数字来表达。
Limiting the extraction of great amount of heat from the underground even more is the low thermal conductivity and low thermal diffusivity of rocks . 由于岩石的热导率和热扩散率都比较低,更加限制了地下热能的大量抽取。
