We found that when increasing the noise intensity the output signal-to-noise(SNR) of the Chay neuron system went through a local maximum at the optimal noise level, which showed the occurrence of coherence resonance.
随着噪声强度的增加,发现在某一优化噪声水平处,信噪比经过极大值,这意味自共振的发生。

Variational method of characteristic value of non-self-conjugate compact operators in complete space is used,and the point spectrum of operators based on weak topology has been discussed in Banach space and Hilbert space.
运用完备空间中非自共轭紧算子特征值的变分法,在Banach空间和H ilbert空间中讨论了基于弱拓扑的算子的点谱,在不要求算子具有紧性的条件下,运用代数拓扑的方法,将完备空间中的算子的点谱进一步推广,推导过程与算子空间的特征子空间的拓扑性质无关。
