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。
Correspondingly,the autonomous stochastic resonance induced by noise was also studied.
研究了确定的和随机的神经放电数学模型中的鞍-结分岔的动力学行为,随机模型中靠近鞍-结分岔点的随机节律被揭示为随机更新过程;还研究了相应于分岔点附近的随机自共振机制。

In 1985,Axler conjecture ap(0<p<1) is self-conjugate.
Axler猜想当0
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。
Some properties of self conjugate matrix over subspace are discussed and a necessary and sufficient condition for the existence of of solution inverse prolem Ax=b is obtain .
讨论子空间自共轭阵的一些性质，得到了反问题Ａｘ＝ｂ有解的充要条件。
