When presented with long depolarizing current pulse of constant amplitude, most of the neurons exhibited pronounced adaptation of spike frequency. 在受到长的强度不变的去极化电流时,多数神经元表现出明显的锋电位频率适应。
Results: The neighbor comparing filter method showed better of effectiveness on EEG signals with simple interference pulse as well as serial interference pulse, and it had little influence on sharp and spike waves. 结果:邻域比较滤波法对叠加有单个噪声脉冲及连续噪声脉冲的脑电信号有很好的去噪效果,对尖波和棘波几乎没有影响,EEG信号无失真。
The paper analyzes the reasons of producing pulse spike in the experiment of measuring thermal conductivity of poor conductor by flash method. The experimental apparatus and data acquisition method are designed in order to reduce and eliminate the disturbance of pulse spike. 分析了用闪光法测定不良导体热导率实验中脉冲尖峰产生的原因,并在实验装置和数据处理方面设计了减小和消除脉冲干扰的方法。
