变化五：竞争格局从“三足鼎立”到“多元博弈”传统存储行业长期由三星、SK 海力士、美光三家主导 DRAM，三星、铠侠、西部数据、美光、SK 海力士主导 NAND，形成稳定的 “三足鼎立 + 五强割据” 格局，定价权、技术路线、产能节奏高度集中。但 2025—2026 年，随着 AI 需求爆发、先进封装独立成链、本土厂商技术突破，行业正式进入多极竞争的全新博弈阶段。
"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.
