Soil thermal properties, including thermal diffusivity (α), thermal conductivity (λ), and volumetric heat capacity (C), are basic parameters describing the ability and efficiency of a soil to store and transfer heat. Soil thermal properties influence heat and mass transfer in soils and therefore have fundamental effects on the energy balance at the ground surface, water exchange between the soil and atmosphere, and engineered structures. Accurate determination of soil thermal properties is essential for describing thermal regimes that influence the rates of physical, chemical, and biological reactions and processes occurring in soil.

热脉冲技术的进步：测量土壤热特性的改进

土壤热特性，包括热扩散率（α），热导率（λ）和体积热容（C），是描述土壤存储和传递热量的能力和效率的基本参数。土壤的热特性影响土壤中的热量和质量传递，因此对地表能量平衡，土壤与大气之间的水交换以及工程结构具有根本性的影响。准确测定土壤的热特性对于描述影响土壤中发生的物理，化学和生物反应和过程的速率的热状态至关重要。
