提出了一种新的基于小波包变换 和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题； 并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了 小目标的精确检测(The wavelet packets were applied to decompose the image into pyramid subbands at different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact detection result was obtained. )

单元刚度矩阵转化为整体矩阵，如何在MATLAB中实现(stiffness matrix THE BELOW ELEMENT MATRICES AND LOAD VECTORS ARE IN THE NODAL COORDINATE SYSTEMS. GRAVITY AND TRANSIENT EFFECTS ARE INCLUDED.)

说明：  MATLAB语言是一种广泛应用于工程计算及数值分析领域的新型高级语言，自1984年由美国 MathWorks 公司推向市场以来，历经十多年的发展与竞争，现已成为国际公认的最优秀的工程应用开发环境。MATLAB功能强大、简单易学、编程效率高，深受广大科技工作者的欢迎(MATLAB language is a widely used engineering calculation and numerical analysis of the new high-level language, since the United States in 1984 by the MathWorks to market since the company, after ten years of development and competition, has become internationally recognized best engineering applications development environment. MATLAB powerful, easy to learn, programming efficiency, greatly welcomed by the vast numbers of scientific and technological workers)
