"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.，推荐阅读新收录的资料获取更多信息

第一，五代时期，那些骄兵悍将——动不动就杀死（旧）节帅，拥立新节帅、新天子的中下层军官什么样，何承训就什么样。那种忘恩负义、背信弃义、毫无节操、数次背叛，在当时中原地区的军队中下层中是常态。
