专利摘要显示，本发明公开了一种基于高轨道角动量量子态测量射频电场的方法，首先利用里德堡原子 的高轨道角动量量子态探测射频电场，并通过外加磁场或电场调控的方法，使得里德堡原子能够在一定 频率范围内连续测量射频电场，拓展了基于里德堡原子的电场计测量射频电场的频率范围。本发明方法 提出以共振方式测量，通过匹配共振频点，在共振频点处，电场与原子具有更强的耦合，通过电偶极跃 迁，可以实现更灵敏的测量；此外，提出利用引入外场调控的方式，通过改变外部磁场的大小可以精确 调控原子能级的塞曼分裂，或利用外部电场调控里德堡能级的整体移动，使能级间隔与待测场强频率相 匹配，进一步拓展了可探测电场的频率范围。 天眼查资料显示，航天恒星科技有限公司，成立于2000年，位于北京市，是一家以从事科技推广和应用 服务业为主的企业。企业注册资本137986.886019万人民币。通过天眼查大数据分析，航天恒星科技有 限公司共对外投资了6家企业，参与招投标项目5000次，财产线索方面有商标信息3条，专利信息1108 条，此外企业还拥有行政许可62个。 金融界2025年7月12日消息，国家知识产权局信息显示，航天恒星科技有限公司申请一项名为"一种 ...

在全球贸易摩擦加剧的大背景下，野村警告，全球经济正在驶入未知水域，市场对政策风险的低 估或将成为下半年的一大隐患。 在周四举行的一场面向中国媒体的在线交流会上， 野村全球宏观研究主管及全球市场研究部联席 主管Rob Subbaraman 表示， 全球经济正步入一个充满不确定性的"未知领域"。 他指出，从美 联储的政策路径到特朗普政府带来的经济政策变化，再到地缘政治风险升温，全球市场正面临自 金融危机以来少见的多重风险叠加。 Rob警告， 美国将在下半年面临 "通胀回升+增长放缓"的典型滞胀压力，美联储将非常谨慎，直 到12月才会降息，且降息幅度可能低于市场预期。 他特别提醒，目前美国企业因抢进口库存偏高， 关税尚未真正反映到消费者物价中，但随着Q3 企业补库，进口成本上升势必传导至通胀，预计四季度美国核心CPI将反弹至3.3%。 Rob表示： " 我们将在未来几周进入一个关键时刻 ，因为在接下来的几周里，我认为我们将开始看到更多证据表 明关税正在影响美国的经济数据。" 对于特朗普提出任命"影子美联储主席"的想法，Rob认为， 即将到来的关键人事变动可能为此提 供实际通道 ： 明年1月底，美联储理事Adrian ...
