Here are three core contents of such framework:(1) cognitive process is reflected by the temporal, frequency, and spatial evolutions of EEG signals;(2) cognitive process is reflected by different nonlinear oscillations and transients of EEG signals;(3) cognitive process is reflected by the linear/nonlinear coupling and synchronization of EEG signals at different brain regions.

本文的一个理论创新在于首次提出认知动力学系统这一新概念，使得对认知功能的研究建立在一个理论框架下，其核心内容包括三方面：(1)认知过程通过EEG脑电活动在时间，频率，空间上的动态演化体现出来；(2)认知过程通过EEG脑电活动的非线性振动与各种刺激诱发的暂态体现出来；(3)认知过程通过EEG脑电活动在各脑区的相互耦合与同步谐振体现出来。

The numerical results indicate that the operator splitting method effectively suppresses numerical oscillations in the cases of high air bearing number. The numerical results show that both air lift force and pitch moment increase with the ratio of the slider's rail height to the air film characteristic height and the air bearing number, and finally reaches to stable value.

比较在不同轴承数下的气浮力和纵倾力矩发现：同一轴承数下，气浮力随气膜特征厚度减小而增加；当磁头槽台高度与气膜特征厚度的比值相同时，气浮力随轴承数增大而逐渐增加直到达到某一值后保持不变；纵倾力矩随轴承数增加而增大到某个最大值后减小。

此方法计算得到的波函数模的平方与利用四轨道紧束缚方法计算碳纳米管体系所得的结果，在形状以及量值方面吻合得很好。

The ordering parameters of GaInP are deduced from the polarization dependence {E||[110] and E||[1 0]} of the PR signals from the emitter regions. The ordering related piezoelectric fields are found to influence the electric field, as evaluated from the observed Franz-Keldysh oscillations, in the GaInP region. According to the experimental data of the as-grown GaInP/GaAs/GaAs samples, we find that for the same emitter doping level the emitter field in the more ordered materials is smaller than in the less ordered sample.

经由分析A系列样品的FKOs信号，估算出射极/基极区域的内建电场，加上极化实验的结果，可以估计磷化铟镓的有序程度；因为压电场的关系，发现当GaInP能隙越小时，内建电场也会跟著降低；温度变化实验，验证其内建电场会随著温度增加而变大，只是变化量不甚明显；利用Varshni及Bose-Einstein方程式来估计一些与温度相关的参数值，并与相关文献比较，其结果颇为相符。
