摘要：

In situ observation technique is employed to study the fractal growth in a thin isothermal aqueous-solution film of Ba(NO3)2. The micromorphology and the growing process of the fractals have been investigated. The experimental findings provide direct evidence that the fractals are formed by random successive nucleation. A nucleation-limited-aggregation (NLA) model is proposed to describe the fractal growth in our system. A computer simulation using the NLA model is also presented.
