研究表明，综放沿空留巷受采场矿压影响时间和程度随留巷煤柱宽度的增加表现出明显滞后现象以及位移和压力增长的不同步现象。

The study indicates that with the increase of the coal pillar width the peak mining stress delays its appearance and the increase of the displacement and stress are not synchronous.

结果表明，随着损伤程度的增加，碳纤维布加固后框架的最大裂缝宽度越大、碳纤维布应变滞后也越大；

The results show that the longer the damaged degree, the widther the cracks and the more the CFRP strain delay.
