摘要
提出了联系相变动力学的宏观热力学理论与微观聚集过程所需解决的若干物理问题:在聚集过程中如何引进粒子间的相互作用能?如何定义系统的自由能、熵、表面和表面能?如何引进温度和热激动的影响?如何考虑这些效应所引起分维的变化?如此等等.
Problems are proposed which would have to be investigated in order to clarify the relation between the macroscopic thermodynamic theory of kinetics of phase transitions and the microscopic process of aggre- gation:In the process of aggregation,how to introduce the interaction be- tween particles?How to define the free energy,the entropy,the surface and surface energy for the aggregate?How to introduce the effect of tempera- ture and thermal agitation?How to calculate the change of fractal dimen- sion caused by these effects?And so on.
