摘　　要：用英国ＨＹＳＣＡＮⅡ测氢仪实验研究铝液氢含量表明，原材料中的气孔存在着遗传性，原材料中的氢也存在着遗传性，而气孔中氢的遗传只是原材料中氢的遗传的一部分，相应地提出了遗传效率的概念。The results of hydrogen determination in aluminium melt by british apparatus HYSCAN Ⅱ show that both hydrogen porosities and hydrogen content in raw materials possess the character of heredity. The hydrogen heredity in porosities is a part of the hydrogen heredity in raw materials. Accordingly, a concept of heredity efficiency has been proposed.

关 键 词：气孔 遗传性 遗传效率 熔炼 氢 铝熔体 铅铸件
