When we dig a tunnel in sericite quartz-schist with dobby drills, regular bending of the boreholes appears, which affects drilling speed and the borehole quality.
在绢云母石英片岩中开挖隧洞，使用多臂钻造孔爆破，出现钻孔有规律的弯曲现象，影响了钻爆速度和成洞质量。
The dynamic mechanical comparison results of sericite-quartz schist and sandstone show that sandstone is more sensitive to strain rate than sericite-quartz schist.
综合绢云母石英片岩和砂岩动态力学性能的对比结果可知，砂岩比绢云母石英片岩对应变率的变化更敏感。
