The cold-heat cycle underground is closely related to the hydrogeological characteristics of various rock and soil stratum (aquifer) when groundwater sourceheat pump system is running.
地下水源热泵系统运行期间，地下冷热量循环过程与地下不同岩土层（含水层）的水文地质特征密切相关。

The theoretical model can be applied to the design and analysis of soilsourceheat pump system.
该理论模型可应用于土壤源热泵系统的分析和设计中。
