1·The scientific and philosophy location of complexity concept was discussed, and a definition was given that" there are many distinguishable states that are meaningful, uncertain and nonperiodic".
讨论了复杂性概念的科学及哲学定位，给出复杂性概念的一个界定：“存在多个有意义、不确定、非周期的可区分状态”。
2·This paper explains a new nonperiodic Amplitude-Phase Code, which has multi-level quantized amplitude and low auto-correlation sidelobes.
本文提出一种新的非周期幅相码，这种码具有多种幅度和相位，其自相关函数副瓣电平比较低。
3·Complex implies just that, nonlinear implies recursion and higher mathematical algorithms, and dynamic implies nonconstant and nonperiodic.
复杂意谓它就是那样，非线性意谓递归和更高数学法则，而动态意谓非常数及非周期。
4·The window Fourier transform(WFT )is one solution to the problem of better representing the nonperiodic signal.
窗口傅里叶变换能够更好的解决关于非周期信号的表示问题。
