最近几件事，把中美之间的差距，看得明明白白。 美国东北部被风雪席卷，近40万人遭遇停电，而且停电人数还在不断增加。同样是多风雪的地方，中国却很少出现这么大规模的停电，最多就是个别区域短 暂停一会儿，很快就能恢复。 其实核心差别很简单，美国的电力公司都是私营的，做生意优先考虑赚钱。 要是遇到大风大雪，供电要亏钱，他们就敢直接断电，之前加州就发生过这种事。 而中国的国家电网是国有的，优先保障老百姓用电，哪怕亏钱也要扛住。 更厉害的是，现在中国的发电总量，比后面九个国家的总和还多，除了煤炭占55%，剩下的都是清洁能源，比很多地方都强。 不光是美国，日本的福岛核灾也早就暴露了私营电力的问题，东京电力为了保股价，迟疑了一天才采取措施，最后造成了严重后果，而这背后还有美国股东 的影子。说到底，还是制度不一样，国有体制才能给老百姓最实在的安全保障。 这些年，中国在很多领域都实现了弯道超车，军工领域尤其明显。最近美国终于公布了他们的六代机F47的完整造型，不再藏着掖着，本以为能惊艳世界， 结果刚曝光就被网友嘲笑"一出现就落后"。 为啥这么说？首先，这款F47还只是PPT阶段，连真正试飞都没做，更别说量产了，预计要到2032年 ...

Q&A 中航沈飞 20260127 摘要 歼 35 预计 2026 年实现内外销突破，成为中航沈飞核心增长点，外贸 市场盈利空间巨大，或将助力公司实现战略升级。 全球五代战机市场中，F35 订单量超 F22 全生命周期 18 倍，表明第二 代五代机具备更大市场潜力，为歼 35 提供了市场参考。 F35 成功因素在于共享核心性能、降低研发成本、缩短研制周期，并拓 展客户群体和服务军种，提高生产效率，这些经验对歼 35 发展具有借 鉴意义。 F35 单机生产工时大幅降低，交付及时性提升，无故障运转时间延长， 成本显著下降，这些生产效率的提升是订单增长的重要推动力。 五代机研发规律显示，首款五代机研发难度大、成本高，第二款可共享 核心性能；销售上，首款客户单一，第二款服务多军种并出口；生产上， 第二款可直接应用首款筛选的核心供应商。 歼 20 与歼 35 在研发上共享航空工业集团的核心技术，销售上，歼 20 服务国内空军，歼 35 力争出口，生产上，歼 35 可直接应用歼 20 筛选 的核心供应商。 歼 35 有望成为军贸出口核心型号，得益于技术共享、多版本适应性、 中国工业基础提升，以及在研制、销售和生产方面的优 ...
