数值模拟结果和客观分析结果的比较表明，非静力中尺度数值模式MM5有能力再现地面以上大、中尺度环流系统和热力场；

The comparisons between results of simulation and objective analysis have shown that MM5 has the ability to replicate large scale and mesoscale circulation systems and their thermodynamic field.

引入了轴向循环流动的概念，且利用ANSYS有限元分析软件对非啮合双螺杆挤出机轴向循环流道中的非牛顿流体等温流动进行了三维模拟分析。

Axial circle flow was introduced. The isothermal flow analysis of non-Newtonian fluid in axial circle region of a non-intermeshing counter-rotating twin-screw extruder was concerned.
