1、PPD makes the critical radius and the potential barrier of nucleation of wax crystal increase, and makes the separation of wax from waxy oil difficult.───降凝剂提高了蜡晶析出的临界半径，增大了成核位垒，使蜡晶析出困难。
2、The results showed that nanoparticles accumulation at the vapor-liquid interface decreased embryo bubble radius and the potential barrier of nucleation, facilitating liquid nucleation.───结果表明，纳米颗粒在界面处的吸附可减小核化的平衡胚泡半径，降低沸腾核化势垒，有利于核化的发生。
