对于一个不收敛的级数，经过多次迭代以后会随着参数取值的不同而表现出不同的性质，由此可以观测到湮灭、平衡、混沌等现象。在复空间下，这种现象可以用julia集的图像表现出来。(For a non convergent series, after many iterations, it will exhibit different properties as the parameter values vary, thus the phenomena of annihilation, balance and chaos can be observed. In complex space, this phenomenon can be represented by the image of Julia set.)
