UFD

Constraint condition is advantage of the yield of UFD too.

外加约束条件可提高UFD得率。

And a small quantity of m-UFD ( surface modified UFD) with 0.2% weight percentage can improve the flexural strength and hardness by 35.4% and 29.8% respectively. The m-UFD was superior to n-UFD ( not surface modified UFD).

加入0.2%（质量分数）的改性纳米金刚石后，复合树脂的挠曲强度和硬度分别提高35.4%和29.8%，改性金刚石的增强作用明显优于未经改性的金刚石；
