The molecular weight of the third material is the smallest, It's flexure strength and impact strength are low.
2
分别以应力分析仪和显微硬度仪测试两组试件的挠曲强度和硬度值。
The flexural strength and hardness of the specimens were tested with an instron testing machine and a microhardness tester.
3
结论牙托粉的分子量和分子量分布对义齿基托的挠曲强度和冲击强度有较大影响。
Conclusion the molecular weight and the distribution of molecular weight of denture base powder obviously affect flexure strength and impact strength of denture base.
