【摘要】 相变材料的选择主要依据是相变温度．根据实验要实现的致冷目标，依次选定相变温度，再据相变温度选择相变材料．通过加入适当比例的成核剂和增稠剂，以解决无机相变材料的主要问题：过冷现象和分层现象．最终选择、配制出合适的两级相变材料体系，即：Ca（NO3）2·4H2O＋4．7％碳酸盐成核剂＋1．9％增稠剂体系，和Na2CO3·10H2O＋6％硼酸盐成核剂＋4．5％增稠剂体系．更多还原

【Abstract】 That choosing phase-change material bases on phase-change temperature. In the case of the drop in temperature aim, first of all, to elect phase-change temperature in series, then choose phase-change materials. Adding the fitting proportional core reagent and dense reagent in the tacts, so as to solve the main phase-change material problems; overcooling and layer-built. Finally, this paper documents that choosing, testing and making the suitable two phase-change material systems which are Ca（NO₃）₂.4H₂O +4.7% carbonate core-reagent + 1.9% dense-reagent system and Na₂CO₃ .10H₂O + 6%borate core-reagent +4.5% dense-reagent system.更多还原
