It employs the complex-valued step function to build neural model, then constructs network structure and decides the number of neurons; it adopts complex-valued Hebbian rules and inner product way to calculate the net weight matrix; then it analyzes the convergence of the network by taking advantage of the definition of energy function. In the image pre-processing stage, 2-dimensional Fourier Transform and Euler's formula are used, respectively, to transfer a gray-scaled image into phase information needed by the complex-valued neural network when stores the traffic sign. In the image post-processing stage, phase inverse transformation is used to change the phase image to gray-scaled image.

采用复数阶跃函数构建了神经元模型，建立了复数Hopfield神经网络结构，并且确定了网络中神经元的个数；借助复数Hebbian学习规则和复数内积法给出了网络权值的确定方法；借用复数网络能量函数的定义，说明了复数识别网络的收敛性；在前期的图像数据处理部分，分别使用离散二维傅里叶变换和欧拉公式，给出了将灰度图像数据转化为复数网络所需要的相位信息的方法，实现了网络对路牌的记忆存储；在后期的图像还原部分利用相位逆变换的方法，实现了相位图到灰度图转化。

It consists of four parts as follows:The first part details the background and causes of the Marshall Plan and discusses the formation and evolvement of the idea of European integration in the Marshall Plan.

In an experiment of constructing a phylogeny of the Eutherian orders, its results not only support the Rodents,(Ferungulates, Primates grouping, but also give an evolutionary tree that is identical to the one constructed by the maximum likelihood method, which indicates that sequence distance defined is very effective to measure the relatedness between sequences.

在研究基于基因组序列的进化关系的实验中，不仅支持了哺乳类动物中（啮齿动物，（灵长类动物，Ferungulates））进化关系分类的结论，而且构造的进化树也与由最大似然方法构造的进化树完全一致。这充分说明了我们给出的序列距离对度量序列相似性是非常有效的。
