基于TKGK实验台的实验数据编码，已经定义好控制的类型(TKGK test-bed based on experimental data encoding, has good control over the definition of the type of)

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

采用PCM方式对语音信号进行编码和解码，文件包含编码解码函数和量化误差计算函数(PCM voice signal by means of encoding and decoding, encoding and decoding functions and the file contains quantization error calculation functions)

梳状导频方式下OFDM系统的LS、LMMSE算法比较(Comb Pilot OFDM system under LS, LMMSE algorithm)

说明：  DPSD算法，用于滤波的，已经用于核磁共振技术很多年了，相当成熟了，希望对大家有用(DPSD algorithm for filtering, nuclear magnetic resonance technique has been used for many years, very mature, we hope to be useful)

云南电网结题程序，用于计算110KV侧的电压谐波含量。(Yunnan Power Grid node title procedures ，used to calculate the voltage of 110KV side of the harmonic content)

协同PSO算法是运用协同组合方法，采用K均值来分类，PSO辅助来实现聚类分析(PSO algorithm is the use of collaborative synergistic combination of methods, the use of K-means to classify, PSO assisted to achieve clustering analysis)

说明：  对用refprop调用实际物性对布雷顿循环进行仿真计算(The simulation calculation of Brayton cycle by using RefProp to call actual physical properties)

该程序完成的是通过使用所提供的链码（一种方向码）来画出链码所表示的轮廓。所画轮廓在原图上是黑色的线。(the code is used for draw the outline of the region of interest which is show by the chaincode)
