对于手机"磁吸充电"的爱好者来说，他们很可能又将被背刺一回。 近日有外媒分析了据称是三星Galaxy S26系列机型的官方保护壳渲染图后，认为三星这一新旗舰的官方保 护壳同时提供了带有磁环和不带磁环两种版本。 但问题在于，如果手机本身（机身内）自带磁体，那么官方就不应该推出不带磁环的保护壳（因为这会令 磁吸失效）。因此从这个细节他们推测，三星Galaxy S26系列机型很可能并没有内置磁体。也就是说，与 迄今为止的其他安卓手机一样，都需要用户另外购买"磁吸壳"，才能使用磁吸充电功能。 那么问题就来了，为什么安卓阵营的手机厂商，会对集成在机身内部、自带磁体的"真·磁吸充电"设计，积 极性如此不足呢？ 磁吸快充确有"公版"标准，但却可能是个坑 提到智能手机上的磁吸方案，苹果的MagSafe磁吸生态注定就是个绕不过去的话题，那么这是不是因为苹 果已经有专利在先，所以导致安卓厂商的技术创新受阻了呢？是，但也不完全是。 这是什么意思呢？简单来说，就是安卓厂商可以用"苹果无线充"的绝大部分设计，但唯独在磁体的排布上 不能"照抄"，否则就会构成对苹果的侵权。可是在磁体设计"必须原创"的基础上，最后实现的固定效果又 必须要与 ...

Core Viewpoint - The article discusses the recent dramatic decline in DDR4 memory prices, marking the end of a prolonged price surge driven by AI demand and speculative trading in the market [2][4]. Group 1: Price Decline and Market Dynamics - DDR4 memory prices experienced a rare flash crash, with an intraday drop nearing 20%, as 8GB prices fell from 260-270 RMB to 180-190 RMB, and 16GB prices dropped from 800 RMB to 650 RMB [2][4]. - The price surge of DDR4, which saw a 386% increase last year, was primarily fueled by the demand for AI computing power, leading major manufacturers like Samsung and SK Hynix to cut DDR4 production capacity [4]. - The market was misled into believing there would be a long-term shortage, resulting in panic buying and speculative trading, which created a price bubble detached from actual market value [4]. Group 2: Future Outlook for DDR4 and DDR5 - By 2025, DDR5 is expected to penetrate 70%-80% of the PC and server markets, while DDR4's market share will drop below 30%, with demand primarily remaining in long-cycle products like medical devices [5]. - Experts predict that as mainstream manufacturers transition to DDR5, DDR4 demand may face a steep decline, further squeezing its market space [5]. - The end of the DDR4 super bull market is anticipated, with the memory market expected to return to rational development driven by supply and demand rather than speculative trading [5].

每经评论员 赵李南 2月10日，中芯国际发布业绩快报。数据显示，2025年中芯国际未经审计的营业收入为673亿元，再次创 下历史新高，同比增长16.5%。在营收高歌猛进的同时，中芯国际2025年的归母净利润约为50亿元，虽 然保持同比增长，但若拉长周期看，这一数字远未回到2022年的巅峰水平。 笔者认为，对当下的中芯国际而言，归母净利润并不能完全反映经营状况。在半导体产业从消费电子向 人工智能（AI）转型的当下，在国产替代的疯狂扩产周期中，看归母净利润不如看EBITDA（息税折旧 及摊销前利润）。 第一，从现金流量表更能看出中芯国际被隐藏的真实战力。与历史峰值相比，如果只看利润表，中芯国 际似乎陷入了"增收不增利"的怪圈。但如果翻开现金流量表和资产负债表，则会发现一个完全不同的故 事。 公告显示，2025年中芯国际的资本开支高达81亿美元。这意味着，中芯国际2025年的资本开支占到全年 营收的八成以上。这种高达80%~90%的"资本开支/营收比"，在全球集成电路代工行业中处于较高水 平。而根据中芯国际预测，其2026年的资本开支仍将维持在超80亿美元的高位（与2025年相比大致持 平）。 在重资产的半导体行业 ...
