摘　　要：对水份和膨润土含量不同的型砂样品,分别用两种方法测量了他们的紧实率,不仅进一步证实了基于γ射线吸收原理测量型砂紧实率方法的有效性,而且依据重建的数学模型可以实现型砂紧实率的在线检测和控制。When the moisture and bentonite content are different, the compactibilty of molding sand are systematically measured by two means, respectively. The experimental results further verify that the measuring method based on the principle of γ-ray absorption is effective. Furthermore, an on-line detection and control system for the compactibihy of molding sand can be developed according to the reconstructive mathematical model in this study.
