This study compared an automixed elastomer with five hand-mixed elastomeric impression materials by counting the number of voids at a predetermined site using 6 X magnification. Although no samples were free of voids, automixing produced substantially fewer voids than hand mixing.
本研究通过使用6倍放大倍数计算预定部位的气泡数量，将一种自动混合弹性体与五种手工混合弹性印模材料进行了比较。尽管没有样品完全没有气泡，但自动混合产生的气泡比手工混合少得多。
