电阻抗层析医学成像软件包，MATLAB语言编写，带有说明，以及演示用法(Electrical impedance tomography in medical imaging software package, MATLAB language, with descriptions and usage demo)

按照文献《complex networks》中192-193页方法生成的scale free network，有详细注释。此方法有助于理解scale free network的生成原理，并画出了P（k）图，可以自己验证r值是否正确。(According to literature " complex networks" in the 192-193 page method to generate the scale free network, with detailed notes. This approach helps to understand the generation of scale free network theory, and plotted the P (k) diagram, you can verify their r value is correct.)

直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )
