In this system, EOG signals produced by the user's eye saccade movements are recorded through electrodes placing on the face, and then the signals are reconstructed and analyzed in real time. By constantly monitoring the electrooculogram signal of the user, the eye mouse is able to recognize several intentional eye motions and in turn, control the cursor on the computer screen.

在此系统中，眼动波讯号是使用者眼睛移动、注视所产生的，而眼动波是透过贴附在脸上的电极所量测到，电极量测到的讯号再即时的经过讯号处理与分析，藉由持续性的的量测眼动波讯号，眼滑鼠系统能够辨识多种眼睛刻意移动的讯号，透过此讯号能够控制电脑上的游标来做动作。

A new strategies for restraining harmonics are presented in the paper, the methods adopt the right carrier frequency and the sine wave superimposed a proper three-time harmonics to make it saddle-shaped wave, produce SPWM waveform to control the inverter switching devices for the on and off .

并提出了一种新的易于工程实现的谐波抑制策略，该方法通过正确选择载波频率和在正弦调制波上叠加一个三次波使之成为鞍形波，产生相应的SPWM波形来控制逆变器开关器件的通断从而改善输出波形。

And then we demarcated the saltation time and starting time of this travelling wave respectively by the first kind of cubic B-spline wavelet and the second kind of cubic B-spline wavelet.

由于行波各频率分量在线路中的传播速度是不同的，而我们所检测到的行波浪涌并非行波的最高频率分量，所以必须选取与所检测到的行波浪涌相吻合的波速。

Formula of the first order component of the harmonic current at saturation is obtained.

这个公式表明：考虑空间电荷波时，在小信号和辐射波与空间电荷波同相的条件下，它将增强谐波电流。

Effects of a single scatterer on the transport properties of a leaky electron waveguide are studied theoretically.

In chapter 6, we discussed the wavefront solution of a kind of lattice differential equation which derives from diverse fields. We obtained the wavefront solution by using sup-subsolution iteration when the coupled functions are quasimonotone, and by applying Schauder fixed point theorem, we also obtained the wavefront solution when the coupled functions have a different quasimonotone property.

在第六章中，我们对一类从实际问题中抽象出来的二阶时滞格微分方程的行波解进行了讨论，用单调迭代的方法讨论了耦合函数具有拟单调性时行波解的存在性，用不动点的方法讨论了耦合函数具有指数拟单调性时行波解的存在性。
