The miscibility of alkali - earth metal tungstates was discused.
合成了一系列混合碱土金属钨酸盐，用粉末Ｘ射线衍射和电子衍射法表征了其晶体结构，并对钨酸钡单晶进行了 Ｘ射线能谱成份分析，所合成的化合物均属四方晶系，Ｉ４１／ａ空间群，钙和钡的钨酸盐能以任意比例互溶，而钙和钡的钨酸盐则以两相存在，并探讨了碱土金属钨酸盐溶混性的成因。
The results of DSC,DTA and static mechanical measurements,show that the GAP binder has a good miscibility with nitrate ester 1,2,4butanetriol trinitrate (BTTN) and its decomposition peak temperatur edecreases with increasing the concentration of the plasticizer.
ＤＳＣ，ＤＴＡ和静态力学性能测试结果表明：该粘合剂和硝酸酯增塑剂１，２，４丁三醇三硝酸酯（ＢＴＴＮ）具有良好的溶混性；随硝酸酯含量的增加，聚氨酯胶片的分解峰温下降。
The following are showed: 1)There is stronger interaction and better miscibility between HTPB and natural rubber in the range of temperature studied; 2) The interaction depreases and the miscibility reducess with the increase of teamperature(3)The value of X23 is dependent on t.
结果表明,在所研究的温度范围内,HTPB与天然橡胶间有较强的相互作用,溶混性较好;随着温度升高,相互作用减弱,溶混性降低;x′_(23)值与所用探针分子种类有关。
