用法例句

An improved implementation of Distributed Lagrange multiplier/fictitious domain method was presented and used to simulate the interactions between two circular particles sedimenting in a two-dimensional channel.

　应用改进的拉格朗日乘子/虚拟区域算法对不同大小的两个圆形粒子在二维方槽中的沉降过程和相互作用进行了直接数值模拟,并进行了实验验证·　结果表明不同大小的两个粒子在沉降过程中的相互作用可以描述为追尾、接触、旋转和分离4个过程,只有当两个粒子尺度差异很小时,才会重复进行DKT过程·　在两个粒子相互作用的过程中,小粒子的运动受到大粒子的影响更剧烈一些,而相反大粒子运动包括运动轨迹和速度所受到的影响则相对较小·
