在ＬＰＧ瓶组非稳态分析的基础上，按定用气量条件得到气瓶温降微分方程的解析解，作出气瓶供气能力设计实用图线。。对变用气量情况，制定了用气量函数，代入气瓶液温变化微分方程，求数值解，制订出气瓶供气能力设计实用图线。
On the basis of the non-steady-state analysis of the LPG bottle group, the analytical solution of the differential equation of the temperature drop of the gas bottle is obtained according to the gas volume conditions, and a practical design line for gas bottle gas supply capacity is made. . For the variable gas volume situation, a gas volume function was developed to substitute differential equations for changes in the liquid temperature of the cylinders, and numerical solutions were developed to develop a practical design line for gas cylinder gas supply capacity.
