摘　　要：基于γ射线吸收原理测量了不同紧实状况下的型砂密度,藉此,提出了一种型砂紧实率测量的新方法,该方法也可能应用于型砂组分的测量。The mould sand density under different compact conditions is systematically measured on the basis of the absorption principle of γ-ray. Thereby, a new method for measuring the mould sand compactability is put forward. It is possibly used to measure the ingredient of mould sand.

关 键 词：γ射线吸收 型砂 密度 紧实率
