Some deformation features that have not been discovered before are found. There are two peaks of displacement in strip mining roadway, and their lag distance is longer.
发现了一些前人未曾揭示的规律，条采巷道闭合变形将出现两个极值，其距离大于普通开采巷道，因此，巷道应在前方峰值压力第二次采动影响时加强支护。
The lag distance of abutment pressure behind working face increases, but the convergence coefficient of vertical stress doesn't change obviously with the increase of mining height.
分层开采与综放开采工作面滞后支承压力变化规律是，随着采高的增大，工作面滞后支承力的距离加大，垂直应力集中系数差别不大。
This time-lag depends on the distance the signal has traveled through the interstellar medium: the longer the distance, the greater the time lag.
这个时间差依赖于信号在星际介质中传播的路程：路程越长，时间差越大。
