利用非线性动力学理论，给出了反应堆噪声功率振荡的非线性特性的差别方法，并对实际信号进行了处理。结果表明热态模拟运行时，反应堆的功率振荡易发生Hopf分叉，圆周形吸引子是存在的，随机噪声会对维数产生较大的干扰，但基本未改变吸引子的形状。该方法对反应堆的详细分析有一定的实际意义。

A method of judging reactor noise power oscillation's nonlinearcharacter is given out. Processing result shows that the Hopf bifurcation is easy to happen to reactor power oscillation, circle attractor exists and even though random noise can affect the dimension, the form of the attractor is not changed. The method has some actual value in reactor running information's analysis.
