摘      要：Dielectric-barrier discharge (DBD) is a typical non-equilibrium gas discharge with AC at low temperature and atmospheric *** this paper the influence of DBD plasma on the crystallization of Cu(NO3)2· 3H2O is *** experimental results show that DBD plasma has great influence on inducing the primary nucleation thus greatly reducing the nucleation ***,by applying DBD plasma,the morphology of Cu(NO3)2·3H2O was controlled during *** crystallization without DBD treatment,quadrilateral Cu(NO3)2·3H2O crystals were preferentially ***,if DBD plasma was applied during the nucleation process,the typical quadrilateral forms of crystal seeds transform to hexagonal *** hexagonal crystals can grow to either hexagonal prism without further DBD plasma treatment or unique contact-twinned shaped hexangular star form under the environment of DBD plasma.
