利用气相色谱法（ＧＣ）和光学显微干涉法研究了硝化二乙二醇（ＤＥＧＤＮ）和硝化三乙二醇（ＴＥＧＤＮ）增塑的硝化棉（ＮＣ）体系中各组分相互作用的热力学性能。所得的混合偏摩尔熵值降低的事实表明：组分间存在较强的作用能。得到了ＮＣＤＥＧＤＮ和ＮＣＴＥＧＤＮ体系的相图。
The thermodynamic properties of each component in the nitrocellulose (NC) system plasticized with DEGDN and TEGDN were studied by gas chromatography (GC) and optical microscopy. . The fact that the resulting mixed partial molar entropy decreases shows that there is a strong contribution of energy between the components. Get the phase diagram of NC DDN and NC TEGDN system.
