而麦当劳中国的 “万店冲刺”,本质是国际连锁品牌在中国快餐存量竞争时代的规模化突围。在消费复苏缓慢、行业内卷加剧的环境下,麦当劳能否在扩张中守住盈利底线、平衡速度与质量,不仅决定其自身在中国市场的长期地位,也将为整个连锁餐饮行业提供重要的发展参照。(作者 | 谢璇,编辑 | 房煜)

There is a plan to prevent such a strike—the Space Surveillance Network, a bevy of sensors that the military uses to track space debris. NASA monitors what’s unofficially known as the “pizza box,” a sort of no-fly zone around the ISS. When pieces of debris are predicted to enter the box—if there’s at least a 1 in 100,000 chance of collision—mission controllers order avoidance maneuvers, firing thrusters that move the ISS and dodge the trash. The technique has been used dozens of times since the first ISS module launched in 1998. But the system only tracks about 45,000 larger pieces, and all sensors have noise. Plus, risk thresholds can miss stuff, sometimes badly. In 2025, Chinese astronauts were briefly stranded at their station after debris hit their return vehicle.
