热扩散率 meaning in English
diffusivity of heat
heat diffusivity
thermal diffusivity
tone'smometric conductivity
Examples
- In materials marked by low thermal diffusivity, the absorption is good .
热扩散率低的物质吸收性好。 - The thermal conductivities and thermal diffusivities of the material must be known .
必须知道各种材料的热导率和热扩散率。 - 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。 - These kinds of measurements are necessary for determinations of thermal diffusivities from the thermal conductivity and densities .
根据热导率和密度确定热扩散率必须进行这种测量。 - 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。
