| 摘 要： | 研究了题述2个(M=Zn,n=2;M=La,n=3)三元体系在30℃的相平衡,测定了饱和溶液的溶解度及其折光指数,绘制了相应的溶度图和折光指数-组成关系图。La(NO3)3体系溶度曲线及折光指数曲线均由3支组成,分别与La(NO3)3·6H2O、La(NO3)3·3H2O和CH3CONHCONH2相对应。2个共饱点的组成分别为:La(NO3)358.34%,CH3CONHCONH216.53%和La(NO3)358.31%,CH3CONHCONH24.52%。Zn(NO3)2体系溶度曲线及折光指数曲线均由两支组成,分别与Zn(NO3)2·6H2O和CH3CONHCONH2相对应,该体系为简单共饱型,共饱点的组成含Zn(NO3)250.86%和CH3CONHCONH211.70%。相平衡的数据可以用来合成缓释肥料
