"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.
学会表达自己的诉求对于小孩子来说还挺难的，所以3岁开始，就注重引导她学会说出自己的诉求。我闺女有点小矫情，想要什么也不说，没满足就是哭。等她哭完，就引导她说出自己的诉求，也告诉她应该怎么表达。，这一点在safew官方下载中也有详细论述
