前两代被视作高端标配的钛金属中框,在 S26 系列上悄悄退场,换回了熟悉的铝合金。抛开营销层面的高级感不谈,铝合金在机身散热、重量控制和加工精度上,其实能提供更扎实的日常握持体验。只不过,iPhone 17 Pro 系列在换回铝合金后,抗击打能力收到大量用户的质疑,「珠玉在前」,S26 系列上铝合金机身的抗摔能力也需要进一步测试。

「解放軍正陷入混亂,」亞洲協會政策研究所的萊爾·莫里斯(Lyle Morris)告訴BBC,僅剩習近平和一名軍委委員的情況是史無前例的。。关于这个话题,51吃瓜提供了深入分析

But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
