HYSCAN II仪器对铝熔体中氢的测定结果表明，铝合金中的氢孔隙率和氢含量均具有遗传性。孔隙中氢的遗传性是铝合金中氢遗传性的一部分。不同形式存在的氢具有不同的遗传效率。据此，提出了遗传效率的概念。研究了冷却速率、熔化条件等因素对遗传的影响以及遗传机制。
The results of hydrogen determination in aluminum melt by using an instrument HYSCAN II show that both hydrogen porosities and hydrogen content in Al alloys possess the character of heredity. The heredity of hydrogen in porosities is a portion of the heredity of hydrogen in Al alloys. Hydrogen existing in different forms possesses different heredity efficiency. Accordingly, a concept of heredity efficiency has been proposed. The effect of factors such as cooling rate and melting condition on the heredity has been studied, as well as the mechanism of heredity.
