• intros：{"brand_intro":"上海敦煌是中国历史最悠久的乐器配件品牌之一，隶属于上海民族乐器一厂，成立于1958年。品牌以\"国货精品\"为定位，早期以民族乐器弦闻名，后拓展至西洋乐器弦领域。敦煌中提琴弦采用国产高纯度镍铬合金与尼龙材料，结合德国进口绕线机生产。品牌品控理念强调\"军工级质检\"，每批弦需通过72小时恒温恒湿老化测试。近年来通过小红书等平台成功打入年轻用户群体，成为国产中提琴弦销量冠军。","product_intro":"敦煌专业级尼龙弦定位为\"入门级国产替代\"，核心卖点是极致性价比（约180元/套）。采用尼龙芯与镍铬合金缠绕，音色偏亮、手感偏硬，适合初学者建立基本功。适用场景为学校乐团、琴行教学及业余考级。与进口弦相比，其音色细腻度不足，但胜在价格仅为 Dominant 的1/3。竞品优势在于\"皮实耐用\"——镍铬合金缠绕层极耐腐蚀，在潮湿环境下不易生锈。","key_specs":{"弦芯材料":"尼龙纤维芯，降低手指疼痛感","缠绕材料":"镍铬合金，耐腐蚀且成本低廉","张力等级":"中等偏高（约12.5kg），帮助初学者训练手指力量","适配尺寸":"4/4标准中提琴","琴弦规格":"A=0.60mm, D=0.75mm, G=0.88mm, C=1.10mm","适用人群":"初学者、学生乐团、预算有限的业余爱好者"}}
