这个是一个好好用的完美挂请大家用用好不好用大家说说(PostScript(R) Printer Description (a.k.a. PPD) files are text files containing information about special features available on PostScript printers such as paper sizes, screen values and fonts available on your printer. These files are in a very specific format that can be read by software applications. The information is used when printing your document by the printer driver for decision making purposes or to invoke particular features of the printer. )

计算损伤结构前后的响应，对已结构的分析具有很好的效果(After calculating the response of the structure damage, the structure analysis of a good effect)

现代数字信号处理 AR（p）模型 matlab程序(ADSP AR(p) model，MATLAB)

电力系统配电网树状网的潮流计算，附有有PDF的程序源码文档说明 (Power system with grid power flow calculation of the tree network, attached to the PDF program source code documentation)

此程序为将a律13折线的PCM信号，进行采样量化输出，和其中的量化精度可达0.01(This procedure will be a law broken line 13 of the PCM signal sample quantization output, and the quantitative accuracy of 0.01)

系统模型辨识中使用维纳滤波器，并对SDA,LMS和RLS算法作比较(system modeling realization using winner filtering ,steepest descend alogrithm,LMS algorithm,RLS algorithm)
