对于,化方式是什么？

The mixed nodulizer can be applied for the key middle and small section casts of ductile iron.

可以在质量要求高的中小截面重要件上应用。

The RE(Y)-Mg-Si-Fe nodularizer had been used to cast heavy sectioned high ductile nodular iron cooling wall castings.

应用钇基重稀土镁复合化剂，造厚大断面高性冷却壁，成功地获得了件中心部位态高性能。

Cataclastic texture which came from brittle deformation made the jadeite quality bed, but the mylonitic texture which resulted from ductile deformation made the jadeite quality good.

在强大剪切应力和钠质流体的共同作用下，铬矿的淡化作用是形成绿色的主要原因。
