“开展主题教育,要以解决实际问题的成效作为衡量标准,即知即改、立行立改,不能拖延,不能虚与应付。”2019年7月,习近平总书记在内蒙古考察并指导开展“不忘初心、牢记使命”主题教育,指导广大党员破解“学归学做归做”的“两张皮”问题。
"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.
