Let the discrete element method (DEM) be developed into the numerical simulation of 3d fluid-solid two-phased flows, the trajectory flexible model of particle group has been put forward.
将离散单元法(DEM)拓展到三维流固两相流的数值模拟中，提出了颗粒群轨道柔性模型。

They also wanted the comfort of a ceiling for the project's budget, and some liability on our part for underperformance. Consequently, the project plan evolved into this two-phased structure.
他们也想项目的预算可以分阶段支付，并且要求我们在执行项目时履行一些义务。
