三羟甲基乙烷和新戊二醇固态相转变贮热的研究

Study of heat reserve in the process of solid phase transition of The Pentaglycerine and neopentylglycols

本文用DSC法研究了三羟甲基乙烷（PG）和新戊二醇（NPG）及其混合物的贮热性能，结果表明它们是较好的固-固相变贮热材料．

DSC method has been used to serch the solid-solid transition of pentaglycerine (PG),neopentylglycal (NPG)and their binarg mixture. Our calorimetric results Show PG,NPG and their mixture are better solid-solid phase change materials.
