贾新光:性能可以测试,安全不能营销
Huan Qiu Wang Zi Xun· 2025-08-04 22:58
通过极限测试展现产品安全性本身并无不妥,但用卡车与乘用车进行正面碰撞的极限测试,其严谨性值 得商榷。首先,从比较对象来看,全球范围内乘用车和载货汽车普遍采用不同的安全标准与测试方法。 汽车碰撞测试绝非简单的"两车对撞定胜负",其核心是在标准化、可重复、可对比的实验环境中,科学 评估车辆在特定事故场景下对乘员的保护能力。标准化的汽车安全碰撞测试一般采用碰撞墙或移动壁障 的方式进行,因为车辆互撞模式测试条件的稳定性容易出现偏差,会影响结果的可比性。 来源:环球时报 日前,某汽车品牌在其新车上市发布会上播放了一则新车碰撞测试视频。视频中,重达8吨的一辆卡车 在与该款新车正面碰撞后,4个车轮弹起、驾驶室和后货箱严重分割,而新车受损轻微。此事很快引来 卡车制造商的抗议,并在舆论中引发争议。 因此,针对汽车行业"营销式安全测试"乱象,一方面第三方检测机构应提高自觉,用更严格的检测标准 塑造公信力;另一方面,行业监管部门应加强测试标准的规范化和结果公开,限制检测机构或厂商"既 当裁判员又当运动员",确保检测结果真实可信,避免本应严谨、让公众放心的安全测试,因过度营销 而丧失公信力。 其次,严格的安全测试需要基于真实场景设定 ...
印媒:中国招收机器人攻读戏剧博士,引发艺术与AI辩论

来源:环球时报 印度《今日印度》杂志网站8月4日文章,原题:中国招收机器人攻读戏剧博士,引发艺术与AI的辩论 这是中国的首次,也可能是全球范围内的首例:一个人形机器人被戏剧与影视专业的博士项目录取。这 台名为"学霸01"的人形机器人将在上海戏剧学院攻读博士学位,专注于中国传统戏曲研究。这一消息是 在7月27日于上海举行的2025世界人工智能大会上正式宣布的。 对许多人而言,"机器人攻读博士"一事的真正意义不在于机器人能否获得学位,而在于当学习、艺术与 机器开始共享同一个舞台时,将会碰撞出怎样的火花。(李迅典译) 在今年早些时候的一次排练中,"学霸01"成功复刻了京剧大师梅兰芳的经典手势"兰花指"。杨青青教授 观察到,现场的人类学生也不自觉地模仿起了机器人的动作。她表示,这一现象并非人机对抗,而是一 种"美学交流"。上海戏剧学院表示,相较于关注机器本身的硬件或代码,学院将致力于探索当技术进入 现场表演这一传统人类领域时,将会发生什么。 不过,这一创举也引发了争议。一些人质疑:无论机器多么精密,机器人是否都能真正理解现场表演所 需要的复杂情感层次? 尽管如此,该实验仍激起了广泛兴趣。此前,"学霸01"的旧版本曾完 ...
