matlab实现混沌扩频DCSK的仿真，其中包括调制解调、噪声信道模拟，以及误码率分析。(Chaotic spread spectrum communication: DCSK)

利用abaqus分析不同铺层的复合材料层合板的圆孔应力集中问题。(Using ABAQUS to analyze the stress concentration problem of circular hole in composite laminates with different ply.)

对任意大小的灰度图像进行zig-zag变换和反变化，或者是对DCT之后的图像进行zig-zag变换，确定其中频信息。(Any size of gray-scale images in zig-zag transform and anti-change, or is the DCT of the image after the zig-zag transform, to determine which frequency information.)

gabor是将图像转换成gabor特征，增强系统鲁棒性，使其不易受外界条件影响；norm是将图像的灰度值统一归一到一个范围内，便于同等使用图像。(gabor gabor is a feature to convert images to enhance the system robustness to make it less susceptible to external conditions affect norm is a uniform gray value image normalized 1-1 range, the same easy to use images.)
