摘　　要：通过测量铝熔体中的氢含量，研究了随过热温度的变化铝熔体中氢含量的变化规律结果表明，温度升高至 ７８０℃附近熔体氢含量发生突变，液态 Ａｌ的 Ｘ射线衍时数据表明， Ａｌ的相关半径和配位数随温度的变化也在 ７８０ ℃附近有所变化讨论了By measuring the hydrogen content in Al melt, the variation of hydrogen content with overheated temperature has been obtained. It is found that an obvious change of the hydrogen content in Al melt occures when the temperature of the melt rises to about 780 ℃, and the X- ray diffraction of liquid Al shows that the correlation radius of Al atom, rc, and its coordination number,Ns, also varied at about 780 ℃. The relations between liquid structure and hydrogen content in Al melt are discussed.
