韦东奕下架练习册 卖书四天销售额超100万_我的网站

一 |     据蓝鲸新闻报道，时隔四天，韦东奕下架了带货链接。

二 | 记者发现，8月22日晚，北京大学数学科学学院副教授韦东奕从其B站账号小店中撤下了此前上架的两套数学练习册链接。    (ECNS)-- China has launched its first large-scale project to recycle and reuse retired wind turbines in Jiuquan, Gansu Province, according to China Resources Recycling Group on Monday.    The project involves refurbishing 25 wind turbines that have been in operation for more than 15 years. It aims to fill a gap in China’s high-value recycling and reuse of large-scale wind power equipment.        Engineers are testing key components, including generators, gearboxes and towers, and repairing and upgrading them using independently developed technologies. The refurbished turbines have shown significantly improved performance, with some core components performing close to the level of brand-new products. They can be reused at small local power stations and for industrial power supply.    Traditionally, retired wind turbines are either sent to landfills or incinerated. The new project increases the material reuse rate of wind turbines from 30% to 70%, helping reduce pollution and save land, according to project manager Jiang Dong.     The company plans to establish a nationwide recycling network to standardize the recycling and reuse of retired wind and solar power equipment.    (By Helen Mo, intern Lin Qiaochu)                    。在下架之前，这两套由他主编的中小学数学教辅，累计销量已突破2.6万件，按售价估算销售额超过100万元。

三 | 8月18日晚，韦东奕时隔一年多更新B站账号，发布视频《一道有趣的数学题》，仅展示一道小学四年级数学题的解法，开头标注“韦东奕主编《数学能力》”。练习册上架初期，不少网友对账号及商品真实性表示怀疑。8月21日，记者从龙门书局出版社了解到，该系列图书是本周正式上新的，在龙门书局官方账号及韦东奕个人账号均有售卖，图书内容偏向培优方向，由韦东奕本人亲自主编。该店铺背后公司为“杭州奕数文化产业发展有限公司”，天眼查显示，公司成立于2026年5月22日，注册资本100万元，法定代表人曹恩铭。与此同时，各大电商平台上也有商家在售该练习册。以抖音“伴学匠官方旗舰店” 为例，其相关商品链接已售出上万单。8月23日凌晨1点多，该店铺直播间仍有150余人在线观看。
