1. 流动性计算公式
假设当前价格为$P_{c}$，用户提供提供流动性的价格区间为$[P_{a},P_{b}]$
$ \LARGE L = \begin {cases} {Δx} \over {1 \over {\sqrt{P_{a}}}} - {1 \over {\sqrt{P_{b}}}} &, \text P_{c} < P_{a} \ {Δy} \over {\sqrt{P_{b}} - \sqrt{P_{a}}} &, \text P_{c} > P_{b}\ {{Δx} \over {1 \over {\sqrt{P_{c}}}} - {1 \over {\sqrt{P_{b}}}}} = {{Δy} \over {\sqrt{P_{c}} - \sqrt{P_{a}}}} &, \text P_{c} \in [P_{a},P_{b}] \ \end {cases} $
