SI12

1.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球化剂，铸造厚大断面高韧性球铁冷却壁，成得铸件中心部位铸态高性能。

2.The increasing of SF and SI reflectes the severity of iron state in body, especially in liver, this has been proved by studies of Piperno and Akiyoski.

SF、SI 的升高反映机体特别是肝脏铁负荷较重，这一点被 Piperno、Akiyoski 等的所证实。
