"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.
到1988年，为了服务新兴的Sun City West分区，Sun Health基金会捐赠900万美元，建成了Del E. Webb Memorial Hospital（现名Banner Del E. Webb Medical Center），同样以老年护理为核心，和第一家医院形成互补，覆盖更多退休居民。。搜狗输入法2026对此有专业解读
