程序给出了0~10发音的语谱图，其中采用分帧函数对信号进行分帧处理然后在用fft算法得到频谱信息，后用灰度图像表示(Program gives the pronunciation of words from 0 to 10 spectra, which employs the signal sub-frame function and then in the sub-frame processing spectral information obtained with the fft algorithm, then said with a gray image)

研究有限矩形区域内，粒子运动到区域边界时会与区域边界发生不同作用（弹性碰撞和吸收两种可能的情况）下的布朗运动。(Finite rectangular region of the particle motion to the regional boundaries will occur with the different roles of the regional boundary (elastic collision and absorption of two possible scenarios), the Brownian motion.)

Multi-Carrier Digital Communications Theory and Applications of OFDM Second Edition Multi-carrier modulation‚ Orthogonal Frequency Division Multiplexing (OFDM) particularly‚ has been successfully applied to a wide variety of digital communications applications over the past several years. Although OFDM has been chosen as the physical layer standard for a diversity of important systems‚ the theory‚ algorithms‚ and implementation techniques remain subjects of current interest. This is clear from the high volume of papers appearing in technical journals and conferences. Multi-carrier modulation continues to evolve rapidly. It is hoped that this book will remain a valuable summary of the technology‚ providing an understanding of new advances as well as the present core technology.
