• intros：{"brand_intro":"迪卡侬（DECATHLON）1976年创立于法国，是全球最大的体育用品零售商，旗下拥有Nabaiji等自有游泳品牌。品牌以\"让运动触手可及\"为使命，通过全产业链控制实现极致性价比。Nabaiji专注于水上运动，产品研发基于全球门店用户反馈，强调\"实用、耐用、低价\"。品控理念采用\"实验室+实地测试\"双轨制，每款浮板需经过500次弯折测试和48小时盐水浸泡测试。在中国，迪卡侬凭借线下门店体验和线上低价策略，成为大众游泳装备首选。","product_intro":"迪卡侬Nabaiji 500浮板是入门级训练板，定位家庭用户和游泳初学者。核心卖点：极致低价（39.9元），EVA发泡材质，基础浮力设计；轻量化（约150g），便于携带；表面光滑易清洁。适用场景包括泳池打腿、儿童戏水、康复辅助。竞品对比中，迪卡侬价格最低，但材质和做工相对简单，浮力不如专业品牌，且耐用性一般。优势在于品牌线下门店多，可现场试握，退换方便。","key_specs":{"材质":"EVA发泡（普通密度）","尺寸":"约40cm×26cm×3cm","浮力等级":"约4-6kg（成人/儿童通用）","适用人群":"儿童（≥6岁）及成人","颜色":"蓝色（主色）","重量":"约150g"}}
