Glass fiber is used to reinforce material for increasing toughness, flexural strength, and tensibility in unsaturated polymer modified concrete.

玻璃纤维则是作为强化材,增加水泥浆体韧性及抗弯、抗拉等机械性。

The toughness may be well improved by postheat treatment which is large in energy consumption and long in working period.

焊后热处理可较好地改善焊接接头韧性，但存在耗能大、工时长等问题。

It is proved that the pressmark of tooth root, the state of carbide and remanentelements in the material have different effects on the toughness of POwer hacksaw blades.

结果证明，机分齿压痕、基体碳化物状况及材料中残存元素等对机韧性有不同程度影响。

Don't underdo it.This doesn't mean you just sit whenever the whim strikes you.It means you set up a practice schedule and keep to it with a gentle, patient tenacity.

这不是说，你只是随心所欲静坐，而是建立一个练习计划，然后一种温柔但又韧性坚持。
