富硅铝的

Study of sapphirine and related mineral association in the high-grade region of the Larsemann Hills, East Antarctica, shows that sapphirine of the area is characterized by its magesio, iron-and aluminum-rich, but silico-poor feature, and the substantial intra-and intergrain changes in compositions. The change is mainly manifested by the Tschermark substitution + Si = 2Al.

通过对南极拉斯曼丘陵含假蓝宝石矿物及有关组合的研究，得知假蓝宝石的成分以富镁、铁、铝但贫硅为特征，其粒间及粒内成分的变化均较为明显，这种变化主要表现为以钙契尔马克代换+ Si = 2Al为主的类质同象置换。

In this study,the separating object was iron-rich impurity particles in Al-Si alloy and dynamic experiments had been done to study the effect of magnetic flux density,cross shape of separator channel and circle size of metal melt no separating efficiency.

文中以铝硅合金中的富铁相杂质颗粒为分离对象，利用流动试验研究了磁感应强度、分离通道截面形状和金属熔体回路尺寸对分离效率的影响。
