Methods: We used PMMA to prepare 30 specimens with the size of 50mm×18mm×2mm each, among which there were 10 specimens with square Co- Cr alloy net put in PMMA and 10 specimens with round Co-Cr alloy net in PMMA and 10 specimens with no Co-Cr alloy net in PMMA.
方法 :用热固化型聚甲基丙烯酸甲酯 (PMMA)制成 5 0 mm× 18m m× 2 m m规格试片 10个 ,在 PMMA中央分别加入方形 ,圆形网眼的铸造钴铬合金网制成 5 0 m m× 18mm× 2 mm规格试片各 10个 ,利用三点弯曲实验 ,用材料力学多功能实验台逐渐加载 ,测定各个样本发生断裂时的力值 ,计算每组样本的平均值 ,通过单因素方差分析和 q检验来分析断裂力值。
