为解决加速度计难以实现定期校准、校准成本高、难以满足长期工作需求等问题,对带有驱动端口的压电加速度传感器的自校准方法进行了研究。利用振动台校准方法以及基于驱动压电元件的逆压电效应,通过对传感器驱动端口电激励可实现驱动压电元件的转换灵敏度测试,并实现加速度计的现场原位校准。将校准结果与振动台校准方法的校准结果进行对比,实验结果表明,在频率范围5~10000 Hz,自校准灵敏度结果与振动台灵敏度校准结果一致,误差在±2%以内,验证了该方法的有效性。

马克思在《在〈人民报〉创刊纪念会上的演说》中运用两个比喻对现代科学技术展开双重批判:以“危险万分的革命家”为喻体,对现代科学技术进行事实维度批判,指明作为社会新生力量的现代科学技术与现代贫困和衰颓之势的对抗是资本主义时代的鲜明特征;以“狡狯的精灵”为喻体,对现代科学技术进行应对态度批判,阐明唯有无产阶级可凭借社会革命规制现代科学技术。在思想上,习近平关于新时代科学技术重要论述与马克思对现代科学技术双重批判一脉相承,对科学技术加以准确定位、理念创新、明确要求,是关于新时代科学技术发展的理论创新成果,为新时代发展科学技术事业提供了理论指导。

人工智能体运用于社会生活领域产生了责任鸿沟的问题,一些学者提出建构复合责任实体对智能体行为负责。实体是由多成员构成的,分布式的代理意味着分布式的责任,智能体能否像其他成员一样负责变得至关重要。按照传统的责任范式,人工智能体不具备责任主体的属性。关系主义提供了新的责任范式,在人机交互的关系模式中,受动者可以根据智能体的行动表现赋予其准责任归属主体的地位;但负责的关键不仅在于智能体的主观体验,更在于实际的权责平衡,“虚拟惩罚”不足以使智能体获得准责任承担主体的地位。必须超越虚拟惩罚,通过“补偿受动者”等方式使智能体真实地承担责任。
