一个挺好用的源程序打包器，北京联高软件公司的，fortran代码转换成chm文档。(A useful tool for converting fortran source files to chm document.)

在有限元分析中的网格划分好坏直接关系到模型计算的准确性，这里是关于网格划分的一些讨论。(In in the analysis of finite element mesh is directly related to the accuracy of the calculation model, there is some discussion about grid division.)

有加减乘除和括号运算功能的计算器，还可以算三角函数(calculator including plus，minus,mutiply,add)

安装32bit-win的spss中PSL所需的所有安装文件，包括PythonPlugInWin32、Python2.5.4、scipy-0.6.0、numpy-1-1.0、PLS.py以及plscommand.xml并附安装说明。 第一步:安装spss17.0 第二步：安装 SPSSStatisticsPythonPlugInWin32_1700.exe 第三步：安装Python2.5.4 第四步：安装scipy-0.6.0和numpy-1-1.0 第五步：复制PLS.py文件到Python安装目录----Python25Libsite-packages 复制plscommand.xml文件到spss安装目录----SPSSIncStatistics17extensions，没有extensions文件夹就新建一个。 第六步：打开软件，导入数据，分析-回归-部分最小平方回归。Ok(Install all the installation files required by PSL in the SPSS of 32bit-win, including PythonPlugInWin32, Python2.5.4, scipy-0.6.0, numpy-1-1.0, PLS.py and plscommand.xml, and attach the installation instructions.)

世界上最好的微积分教材，搞程序的，研究的，数学的都应该了解，这个是James.Stewart的Calculus第七版，英文原版，彩色的，值得珍藏。(The world' s best calculus textbook, engage in programs, research, mathematics should understand that this is James.Stewart seventh edition of Calculus, English original, colorful and worth treasuring.)

最新的关于贝叶斯聚焦算法IEEE文章。该算法通过利用信号DOA概率密度函数实现加权的阵列波前差值法，能实现宽带相干信号的DOA估计，并能减小阵列聚焦误差，提高宽带阵列频域波束形成鲁棒性。(In this paper, we present and study a Bayesian focusing transformation (BFT) for coherent wideband array processing, which takes into account the uncertainty of the direction of arrivals (DOAs). The Bayesian focusing method minimizes the mean-square error of the transformation over the probability densityfunctions(pdfs)oftheDOAs,thusachievingimprovedfocusing accuracy over the entire bandwidth)
