新华社“深海一号”10月27日电（记者叶昊鸣 李鑫）记者27日从“深海一号”船了解到，实现第二次迭代升级的“蛟龙”号载人潜水器近日在菲律宾海盆进行了多次7000米潜次试验并安全返回，顺利完成国家重点研发计划“蛟龙号关键作业技术能力提升及科学应用”7000米级海试。
据了解，此次海试依托中国大洋100航次第二航段科学考察，“蛟龙”号先后在菲律宾海盆开展了3个潜次试验，其中2个潜次试验下潜深度超7000米，最大下潜深度达7056.9米，各项试验指标均达到7000米级海试要求。
“这充分验证了‘蛟龙’号迭代升级和关键部件国产化替代后的可靠性与安全性，巩固提高了我国载人深潜装备领域的技术优势。”中国国家深海基地管理中心研究员孙永福说。
据介绍，在进行此次科学考察前，“蛟龙”号完成了7000米级高能量密度油浸锂电池组换装，安装了国产直驱型低噪直流推进器，扩展了应急液压系统接口，应用了大深度海水液压浮力调节、广视角和高变倍超高清摄像等系统，在电源动力、推进、液压、电气、观通等关键部件的技术能力和系统研制方面取得了一系列技术创新，实现了“蛟龙”号作业效能极大提升。
孙永福表示，“蛟龙”号完成迭代升级和关键部件国产化替代后，随即在多个海域开展了多项深海资源与生态环境科学考察。“这些科学考察将进一步深化国际海洋合作，有力推动我国深海事业发展，助力海洋强国建设。”孙永福说。

This story captures something I noticed in Shanghai too: young people treat the city almost like a shared living room.

The point about low-cost identity is sharp. It explains why small habits can feel bigger than entertainment.

I would love a follow-up about second-tier cities. Chengdu and Hangzhou probably have different versions of this.

The examples feel familiar even outside China. Urban life is becoming more improvised everywhere.

Museum visits, cycling routes, pop-up stores - that mix says a lot about how cities are changing.

The article makes the trend feel human instead of just lifestyle branding. Nice angle.

I like that the piece does not frame this as Westernization. It feels more locally invented.

The writing around public streets becoming social spaces is especially strong.

This reminds me of weekend markets near university areas. Very accurate.
