摘　　要：根据常用液化气体罐车罐体的基本结构,运用微积分的方法,推导出了罐车罐体容积与液位关系的方程。并借助软件运用二分法和牛顿法求解了不同充装率之下液化石油气汽车罐车的液位高度,得出牛顿法与画图法相结合能快速求出任意容积下的液位高度,可为现场判断容器任意容积所对应的液位高度和液位计安装位置是否准确提供理论指导。According to the basic structure of liquefied gas tanker,making use of the calculus method to derive the equation of the relationship between tank volume and liquid level was implemented,including making use of the software,Newton method and dichotomy method to solve liquid level height of LPG vehicle at different filling rates.The results showed that,the combination of Newton method and drawing method can quickly calculate the liquid level height at any volume.This provides a theoretical guidance for on-site determination of the corresponding liquid level height at any volume of the container and the installation accuracy of the liquid level gauge.
