  1. Abstract : by utlizing abundant local resource of ytirium and combining the characteristics of magnesium, barium, calcium and silicon, a sort of composite nodulizer - ytirium - based heavy rare earth nodulizer was developed which is characterized by its good desulphurizing and deoxidizing rate effect, excellent effect to neutralize anti - nodulizing effect of trace elements, strong nodulizng effect and degeneration - resistance, good effect to fine matrix structure, decreased chilling tendency and wide scope of applicatiom using this nodulizer to produce some important castings such as water - cooled wall of blast furnace and roller could increase mechanical properties of central area and casting yield

    文摘:利用江西省豐富的釔基重稀土,結合鎂、鋇、硅、鈣等元素的特性開發了釔基重稀土復合球化劑,該球化劑具有脫硫、脫氧、抗干擾元素、球化和抗球化衰退能力強,細化基體組織,白口傾向小,適用范圍寬等特點,應用於高爐冷卻壁,軋輥等關鍵鑄件上可提高心部力學性能和工藝出品率。
  2. Pca of x1, x2and x3 successions was done, and from these three eigenvector fields, a principal component that its physical meaning is clear and its variance deficiency contribution rate is large ( over 75 % ) is found. and that principal component was defined as an integrative chilling damage index

    將寒害指標x _ 1 、 x _ 2 、 x _ 3序列作主要分量分析,從3個特徵向量場中找出了一個物理意義清晰、方差貢獻率大(大於75 )的主要分量,將其定義為綜合寒害指數。
