IAPWS_IF97(FUN,IN1,IN2) is 104 functions of water properties and derivatives, based on the International Association on Properties of Water and Steam (http://www.iapws.org). Thermodynamic, hydrodynamic and non-linear modeling often requires thermodyn

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
