matlab,davenport风速谱，4阶线性滤波法，绝对可以用！不能用，你砍我！ -Matlab, Davenport wind speed spectrum, the 4 order linear filter method, the absolute can be used! Can not use, you cut me!

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
