In some conditions the fluctuation of stock price is not a continuous process,in order to imitate and analyze the uncontinuous process,a cusp catastrophe model of stock price is set up,in the mean time makes a brief analysis of this model,and finally gives some advices according to the analysis.

针对股票价格变化在某种条件下具有不连续性的问题，对这种不连续的股票价格变化进行了描述与分析。以突变理论为基础，建立了一个描述股票价格短期变化过程的尖点突变模型，并对该模型进行了简要分析。最后，根据分析结果提出了相应的政策建议

The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.
