炒股就看金麒麟分析师研报，权威，专业，及时，全面，助您挖掘潜力主题机会！ 来源：张忆东策略世界 2026年的春季行情，是一场关于"新质生产力"与"全球流动性边际改善"的重新共鸣。近期行情调整颠簸 恰似"倒车接人"，重点布局"十五五规划"的重点领域与具备全球竞争力的中国优势资产。 一、 AI行情：去伪存真而非Game Over，回调只是重定价 核心逻辑：不要被短期的波动蒙蔽了双眼，AI科技革命仍处于"基础设施建设期"，美联储降息周期还将 延续，类似1997-98的互联网浪潮而非1999-2000年。 当前的回调是市场对"大力出奇迹、扩大资本开支以增效"旧叙事的纠偏，及对"Agent颠覆性"新叙事的 适应，叠加美联储人事提名引发的风险偏好变化。我们判断这更像拥挤交易后的仓位与估值消化，而非 产业趋势逆转；只要算力投入持续转化为产品迭代与真实需求，回调就不是AI熄火，而是"去伪存真"后 的再定价、再出发。 1． 资本开支的"豪赌"昭示AI浪潮的巨大惯性：2026年美股六大科技巨头资本支出预计高达 6500亿美元 （高基数下同比再激增55%），中国四大互联网巨头资本开支增速将达 77%。 2． 从"对话玩具"到"生产 ...

答 ：这是一个切中行业痛点的问题。 我们要清醒地看到，面对 1000W 甚至 1200W 的超级芯片，传统的"外部散热"——也就是 简单地把散热器做大、风扇转速调高，或者仅仅依赖外部冷板——已经逼近了物理极限。 问： 当前AI/ HPC 封装散热达到千瓦级别，硅材料遇到瓶颈，下一代颠覆性散热技术目前有 哪些突破？ 我认为， 散热技术正在经历一场从"外部辅助"向"内生重构"的范式转移 。 简单来说，未来 的散热不再是给芯片贴"退烧贴"， 而是要深入到芯片的材料基因和内部血管里去解决问题。 具体来说，我看好 三个维度的颠覆性突破 ，而行业的领军者们其实已经开始行动了。 第一: 是材料层面的"降维打击"，也就是用金刚石和SiC材料的应用 。 当硅（Silicon, ~150 W/mK）本身成为热阻瓶颈时，利用金刚石（~2200 W/mK）替换传统 衬底和均热板是物理学上的唯一解。 技术路径1：金刚石-SiC 复合材料 (Diamond-SiC Composite) 利用金刚石的超高导热与 SiC 的高机械强度，解决纯金刚石脆性大、热膨胀系数（ CTE ） 不匹配的问题。已实现商业化量产（Coherent, Elem ...

The stock market turmoil unleashed by the artificial-intelligence industry reflects two fears that are increasingly at odds. One is that AI is poised to disrupt entire segments of the economy so dramatically that investors are dumping the stocks of any company seen at the slightest risk of being displaced by the technology. The other is a deep skepticism that the hundreds of billions of dollars that tech giants like Amazon.com Inc., Meta Platforms Inc., Microsoft Corp. and Alphabet Inc. are pouring into AI ...
