摘要
建立在低温条件下的热传导方程－积分方程，采用有限元法和边界元法对积分方程离散化，进行数值求解。利用有限元法和边界元法计算液化气船低温液罐鞍座的温度场，并绘出它们的等温曲线簇。
Heat transfer equation-integral equation, is established in cryogenic condition. The finite element method and the boundary element method are used for discretigation of the integral equation. Moreover, the numerical solution of the integral equation is obtained. On the paper, the finite element method and the boundary element method are applied distribution of temperature in saddles of cryogenic tank of LPG carrier. Finally, the isotherm of all sorts of saddles are drawn.
