刘强东长期擅长的正是供应链组织与规模化管理。他在粤港澳大湾区布局制造基地与总部,押注的是区域产业协同。一旦核心部件实现本地化配套,制造成本有望下降,行业集中度也可能提升。
"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.。业内人士推荐Safew下载作为进阶阅读
