版块是用香浓定理来述说扩频通信时传播原理。并用MATLAB的编程软件去建立一个直接扩频的仿真模型的，在排除其他因素的情况下可以观察曲线和动态图去分析直接扩频的可靠程度-Section in aromatic theorem is used to declare the spread spectrum communication transmission principle. With MATLAB programming software to build a simulation model

模式分类中基于BP神经网络的曲线拟合；根据BP神经网络的模型，调用MATLAB工具箱函数，通过对样本数据进行训练，对测试样本数据进行成功的预测，预测的输出值与实际值之间几乎没有偏差。-Pattern classification of curve fitting based on BP neural network Based on BP neural network model, call MATLAB toolbox function, through the training sampl

matlab数值积分算，假设储罐的密度和液氨的压力不变。模拟液氨储罐高架连续点源，在不同泄露速率、稳定度和风速下连续泄漏扩散的情况。当液氨储罐泄漏达到稳定状态时，扩散模型见下式：(During the leakage process, the pressure of the tank and the liquid ammonia density will change with the increase of the leakage amount. This change will be gra
