It is researched that the high rate of network addiction in teenagers is caused by special character of their physiological and psychological development. That the teenagers have not been well grown-up in both body and mind, their self-cognizance and interpersonal relation is changeable, the internet has great attraction, and the government is nonstandard and lack of control to the network makes teenager easily enthrall in internet. It is also researched that it is the complex factors which leads teenagers network addiction.

研究认为，青少年成为网络成瘾的高发人群，是与青少年身心发展的特殊性有着密不可分的关系，青少年时期正是人生处在生理和心理都尚未完全发育成熟的特殊时期，他们的自我探索与认同、人际关系等也都处于不断变化之中，再加上网络本身所具有的吸引力，以及政府对网络管理的不规范和严重缺位，这很容易造成青少年在面对网络时出现过度使用和迷恋现象。

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。
