Clarifying user request The user wrote in Chinese about the Bernabéu stadium's transformation into a rugby venue. It sounds like they could be asking for a news post or social media caption. I need to clarify what they want: a summary, an explanation, or a promotional copy. I think I could explain how the stadium transforms, including details about its retractable pitch and modular seating. I’ll offer a concise explanation and ask for their preferred format, maybe including some bullet points as well.Discussing Bernabéu renovation I need to be cautious about misinformation. As of 2023-2024, Real Madrid's Bernabéu renovation features a retractable hybrid grass pitch stored in an underground greenhouse and is equipped for concerts, NFL games, tennis, and basketball. The user mentioned "秒变橄榄球比赛场地," which likely refers to American football or rugby—though in China, it often means American football. The stadium can host NFL events, even though it hasn’t yet. I could share details about the transformation process and the pitch's mechanism, which can take about 6 to 20 minutes to retract, including all the advanced features.Explaining pitch transformation When hosting American football or rugby, they use synthetic turf or modular turf over a solid slab, complete with markings and goalposts. I need to be cautious about the timing; the term "秒变" suggests quick transformation, but in reality, it can take hours. The turf retraction typically takes around 20-30 minutes, with official claims about 20 minutes for moving the lawn trays. However, a full event conversion could take from several hours to an entire day. I can provide a concise explanation and a short news blurb about this process.Crafting renovation details Let’s create a quick overview of the renovated Bernabéu. It features a retractable natural grass system stored underground. When the grass is retracted, the floor transforms into a multi-use arena. They can lay modular synthetic turf with rugby or American football markings, adjust seating with telescopic stands, and deploy various protection panels. The steps include retracting the pitch, raising floor panels, laying synthetic turf, and adjusting the seating and AV systems. The grass retraction takes roughly 30 minutes, while the full switch can take between 6 to 24 hours. The seating capacity is approximately 84,000 for football and around 70,000 to 80,000 for NFL or rugby.Preparing Bernabéu article The Bernabéu field area is well suited for new revenue streams and year-round events. If the user is looking for copy, I should provide a punchy mini-article in Chinese, complete with a title and 2-3 informative paragraphs. I could also add bullet points explaining the mechanism behind the field's transformation. Including a short section like "解读" and "10秒看懂" could be helpful. I should definitely ask the user what type of content they need, offering options like: “需要我写一段新闻稿/视频解说词/科普长文/社媒文案？”
看点在于：伯纳乌完成翻新后，靠“可伸缩天然草皮 + 地下温室仓 + 可变换地台/看台 + 灯光音视频系统”，把足球场快速切换成多功能场馆，包括橄榄球/美式橄榄球、演唱会等。
简要解读
- 可伸缩草皮：比赛草皮被分成多块托盘，收纳到数十米深的地下“温室舱”（恒温恒湿、补光、通风病害控制），地表腾空。
- 盖板/地台：地面合拢为平整载荷平台，便于车辆进出与大件搭建。
- 临时场地：铺设模块化人造草或临时草皮，喷/贴专用标线；安装橄榄球/美式橄榄球门柱与防护垫。
- 看台与动线：局部伸缩看台和护栏重新布局，设置队伍出入、转播与摄影机位。
- 声光电：可开合屋顶、360°环形屏与音响场景切换，外立面与内场灯光联动。
- 用时预期：草皮表面收放通常在几十分钟级别；完整从足球切到橄榄球赛事场景，含铺设、安检与联调，多在数小时到一天内完成（视赛事规格与转播需求）。
为什么能“秒变”
- 关键不是真正在“秒”级完成全部工序，而是把“草皮生存需求”和“赛事搭建需求”解耦：草在地下活着，地上像场馆“舞台”，能为不同项目快速装台/撤台。
