4月28日，欧洲航空安全局（EASA）又一次用"技术熟悉"四个字搪塞中国商飞适航证的进度，对外宣布中国商飞的C919不可能在今年拿到适航证，预计认 证周期为"未来3到6年"。 很明显，这回我们彻底跟EASA杠上了。 外网报道C919适航证延期 而就在一天后，中国商务部对近日波音公司的3架拟交付中国的波音737Max飞机被退回事件进行了回应。 商务部4月29日答记者问 一直以来EASA都试图用适航证来卡中国商飞的脖子，这六年时间，足够中国再造两架C919，但欧洲的"拖字诀"愣是让适航证成了马拉松。 C919 说实话，看到这一幕，我既觉得荒诞，又忍不住冷笑。 有些人的傲慢，终究会被时代的车轮碾碎，而中国航空人，早就在车轮上焊死了自己的引擎。 欧洲对C919的适航证拖延，堪称教科书级的"太极功夫"。 波音空客双寡头 你看，连"评估"二字都能拖六年，这效率要是用在美国国债违约谈判上，华尔街早就跳楼了。 俄乌冲突和红海危机让空客供应链崩出裂缝，材料产能掉链子，交货周期拖成"三年又三年"。 官方说辞永远是"技术需进一步评估"，但明眼人都懂——空客和波音的奶酪，哪容他人染指？ 这时候若放C919入场，无异于给自家后院点火。 ...

特朗普拒不妥协？美债危机倒逼中美谈判，英伟达CEO暗藏玄机 但特朗普偏要硬撑。他一边喊话要谈判，一边挥舞芯片制裁大棒，甚至点名英伟达：连"阉割版"芯片都不许卖给中国！这操作看得人直摇头：一边求着中国 接盘美债，一边又掐中国脖子，哪来的底气？ 第一部分：谈判大门敞开，特朗普为何装聋作哑？ 最近国际舆论场炸开了锅——美国突然主动向中国递出谈判"橄榄枝"，但中方回应却意味深长。商务部一句"正在评估"，既没把话说死，也没直接拒绝，反 而给特朗普政府留了个"台阶"：想谈？先拿出诚意！ 第二部分：芯片战升级，特朗普的算盘能响吗？ 特朗普的芯片政策，本质是"新瓶装旧酒"。拜登时期搞的芯片出口限制，他非但不松手，反而要加码。这次直接瞄准英伟达，要求连性能缩水的"特供版"芯 片都不准出口。表面看是"杀鸡儆猴"，逼其他国家站队；实际上，这和加征关税一个套路——人为制造筹码，逼中国让步。 可问题是，这招真的管用吗？先看数据：2024年中国芯片自给率已突破30%，预计2025年将达45%。更关键的是，华为昇腾910B、寒武纪MLU370等国产芯 片性能直追英伟达A100。黄仁勋在闭门会上那句"限制出口只会加速中国自研"，可不是客套话 ...
