英语语法分析

The control of the interdendritic flow at the end of the liquid pool is important to prevent the centreline segregation.

改善中心偏析关键在于控制液相穴末端的枝晶间液相的流动状况。

A numerical analysis method is presented to simulate the shrinkage porosity formation in steel castings on the basis of heat flow, interdendritic fluid flow and possible evolution of dissolved gases.

提出了预测铸钢件中缩松缺陷的数值方法，考虑了传热、枝晶间液相流动和气体析出等因素。

The simulation results show that mushy region is compressed and interdendritic solute-rich liquid flows toward the liquid core in the soft reduction action zone at the solidification end of the slab.

在铸坯凝固末端轻压下直接作用区域，两相区受到压缩，枝晶间富含溶质的液相被挤出，相对于铸坯向液芯方向流动。轻压下之后，铸坯中心区域由糊状区内被压缩的固相及残留的液相构成，中心区域偏析指数下降。
