“双线法”在杠杆规则中的数学表达

Double-line method expressed theoretically in the lever rule

杠杆规则是相图复相区中计算共轭平衡相物质相对数量的一个公式。以杠杆规则为依据,利用相似三角形证实了"双线法"是两次运用杠杆规则的结果,是杠杆规则的特例。

Lever rule is a formula for computing material relative quantity of the conjugate phase equilibrium in the phase diagram compound area. In this paper, based on the lever rule, the similar triangle confirmed the double-line method is the result of two using the lever rule, it is a special case of the lever rule.
