计算超声波入射到介质中，与缺陷作用时，其纵波衍射与横波衍射的衍射系数(When calculating the ultrasonic incident to the media, and defects, its longitudinal wave diffraction and the diffraction coefficient of the shear wave diffraction)

用matlab编写的替代数据法，检验某一时间序列是否具有非线性特性(Surrogate data to test whether the nonlinear time series)

关于恒速风电机机组的matlab仿真，可以了解恒速风电机组的相关运行特性(modeling and simulation of Constant Speed Wind Power Unit This simulation gives an example of Modeling and simulation of Constant Speed Wind Power (CSWP) coupled with wind turbine. Latest researches and developments which have been published in imminent journals, you can get it if you are interested in it. Because of the advantages of the CSWP over other generators it is being used for most of the wind applications. Various researches have been done in modelling and simulation field of CSWP coupled with wind turbine. This simulation visualise the researches in the area of study of CSWP, its modelling, simulation and performance analysis of CSWP coupled with wind turbine. )

autocorrelation function for chirp signal

三维重建，三维场景建模，立体视觉matlab源码(Three-dimensional reconstruction, three-dimensional scene modeling, stereo vision matlab source)

说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)

说明：  读取地震数据软件，是地震资料处理的基础性资料(seismic software)

Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorrelation method in this paper．It’S jamm g peculiarity and几out— putting signal’S jamming peculiarity ale explained．At last，these time series models ofnoise FM jalllIIling sig— nal and几outputting signal ale built．(Abstract: Noise frequency modulation (FM) jamming. which belongs to blanket jamming. is already becomethe main form ofnoise jamming at present. because the wideband was gained by it.
