"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.
「最終，即使搭乘愛潑斯坦的飛機讓我能親自視察基金會的工作，但事後這些多年來的質詢，完全不值得，」他寫道，「我真希望我從來沒有認識過他。」，更多细节参见旺商聊官方下载
