利用双协边界元法在时域内对流体晃动进行分析，推导出边界积分方程及相应的边界条件。分析过程中考虑流体粘性，利用时间迭代，逐步追踪流体自由面，因而在流体不断变动的边界上考虑其边界条件。数值结果表明本文的双协边界元法是可行的。

A dual reciprocity method is proposed for the analysis of fluid sloshing in time domain. With a known initial condition

by each time step

the free surface position is traced and zero stress conditions are imposed on it. If time step is small enough

the boundary conditions are considered almost on the true moving boundary. Further study is to be carried out to verify the precision of this method.
