用分子动力学模拟方法研究了与饱和二氧化碳(CO2)海水浓度相近的氯化钠(NaCl)水溶液的结构和导热系数。在不同的压力下，从40米到10000米的深度范围内研究了压力的影响。在8000m以上的深度内，导热系数呈现负的压力依赖关系，而不含CO2的氯化钠水溶液的导热系数呈现正的压力依赖关系。
The structure and thermal conductivity of the sodium chloride (NaCl) aqueous solution in similar concentration to the seawater with saturated carbon dioxide (CO 2) have been investigated by molecular dynamics simulation. The effects of pressure have been investigated under various pressures corresponding to the depth of the sea from 40m to 10000m. The negative pressure dependence of the thermal conductivity has been detected in the depth of more than 8000m, whereas that of NaCl aqueous solution without CO 2 shows the positive pressure dependence.
