"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.
两者的一个重要区别就在于,能不能坚持好、运用好马克思主义立场观点方法。

如果说财务压力是明面上的焦虑,那么规模效应缺失带来的技术困境,则是蔚来心底更深的焦虑。在半导体行业,没有规模就没有成本优势,没有成本优势就没有生存空间——这是铁律。
