isotopic tracer

Linguistically and philosophically, we proved that, firstly, the double corresponding relation that relies on different corresponding base is illustrated by two different understandings: a literal one and a dislocated one.

探讨了英语对等句中两个名词短语间的双重同位关系,论证了以下两个观点:1、双重同位关系的产生源于同位基的不同,这种同位关系外在地表现在对等句理解过程中的字面理解和错位理解,而后者正是隐喻存在的基础;2、对等句的理解过程是有序的,严格遵循由默认值定义域中取值(现实世界中的理解)再到另设定义域中取值(可能世界中的理解)这一过程。

The finite volume method in the non-staggered grid was applied to the prediction of the two-dimensional branched polymer melts through a 4∶1 planar contraction and planar contraction with inset.

选取基于Doi-Edwards模型发展起来的XPP模型作为聚合物浓厚体系的本构关系,采用同位网格有限体积法结合数值求解的稳定化技术首先对4∶1平板收缩流进行了全域模拟,而后对聚合物成型中常见的嵌件收缩流进行了模拟。

The governing equations were established for the viscous,incompressible,Newtonian fluids,which were discretized by the finite volume method based on non-staggered grid.

进而将Level Set算法和同位网格有限体积法进行耦合,模拟了注塑成型充填阶段的三维流动过程,准确追踪到了不同时刻熔体前沿界面,预测并分析了流动过程中不同时刻的压力、速度等重要流动特征。
