"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.,这一点在旺商聊官方下载中也有详细论述
The atmosphere is a ruthless incinerator, and, no matter how the ISS comes down, most of it would be vaporized. But there’s still that chunk of station that could survive reentry. In the best case, where we’re prepared, air traffic controllers and maritime authorities can issue alerts. The station will shed pieces into the sky, and Australians might get a nice view before things kerplunk into the sea. Then the remains of this historic feat of human engineering will sink to the ocean floor, another carcass left to the algae and the microplastics.,详情可参考搜狗输入法2026
