Used with fractal theory, the running state of the system can be analyzed not qualitatively but also quantitatively, and then the faults of complex machinery system can be diagnosed.

运用分形理论，不仅可以定性，而且可以定量地分析系统的运动状态，从而实现对复杂机械系统的故障诊断。

Fractal theory was used to derive the following three IFS based improved image generation methods: IFS with probabilities method, coherence transformation method, and parameters method.

以分形思想为基础，探索了三种基于一般ifs的计算机图像生成技术——带概率的、带凝聚的和带参数的IFS。
