据央视新闻，当地时间2月4日，两位美国官员透露，美国政府已于4日正式告知伊朗，拒绝其提出的更改原定6日的会谈地点与形式的要求。双方此前商定 在伊斯坦布尔举行有多国观察员参与的会谈，但伊朗方面3日突然要求将谈判移至阿曼并以双边形式进行，意图将讨论严格限制在核问题范围内，排除导 弹等美方关切的议题。美方评估后认为，此举可能削弱多边协调效力，故坚持原有安排。 一位美国高级官员表示，美方已向伊朗明确表示"要么接受原计划，要么取消谈判"，而伊方选择了后者。该官员同时暗示，若外交渠道持续受阻，美方将 不得不考虑"其他选项"。目前伊朗驻联合国代表团尚未就此置评。 在此背景下，美国总统特使威特科夫及特朗普女婿库什纳仍将按计划于5日前往卡塔尔进行磋商，但随后将直接返回美国，不再与伊朗代表会面。此次谈 判濒临破裂，不仅反映出双方在谈判框架上的根本分歧，也可能导致地区紧张局势进一步升级。 ...

据央视新闻，2月4日晚，国家主席习近平同美国总统特朗普通电话。 习近平指出，过去一年，我们保持着良好沟通，在釜山成功会晤，为中美关系领航把舵，受到两国人民和国际社会欢迎。我高度重视中美关系。新 的一年，我愿同你继续引领中美关系这艘大船穿越风浪、平稳前行，多办一些大事、好事。美方有美方的关切，中方有中方的关切。中方言必信， 行必果，说到做到。只要双方秉持平等、尊重、互惠的态度相向而行，就可以找到解决彼此关切的办法。今年中美两国各自都有不少重要议程，中 国"十五五"开局起步，美国将迎来建国250周年，两国将分别主办亚太经合组织领导人非正式会议、二十国集团领导人峰会。双方要按照我们达成的 共识，加强对话沟通，妥善管控分歧，拓展务实合作，不以善小而不为，不以恶小而为之，一件事一件事去做，不断积累互信，走出一条正确相处 之道，让2026年成为中美两个大国迈向相互尊重、和平共处、合作共赢的一年。 习近平强调，台湾问题是中美关系中最重要的问题。台湾是中国的领土，中方必须捍卫国家主权和领土完整，永远不可能让台湾分裂出去。美方务 必慎重处理对台军售问题。 特朗普表示，美国和中国都是伟大的国家，美中关系是世界上最重要的双边关系。 ...

据界面新闻， 中国光伏行业协会执行秘书长刘译阳2月4日对界面新闻等媒体表示，近两日，受马斯克团队相关调研消息带动，太空光伏概 念再次引爆市场。 刘译阳表示，太空光伏概念确实"火"出了圈，在资本市场和科技圈也是炸了锅。A股光伏板块，概念股连拉涨停，多篇券商研报认为异质结 (HJT)和钙钛矿技术适合应用于太空领域。 这些研报互相应用、相互回响，诱发了资本市场的空前震荡；国内企业也纷纷表态布局，"万亿蓝海""下一个光伏革命"等等话题的抛出。但 他强调，无论何种技术路线如何演进，真正走向落地，离不开一个前提——成熟、可复制的高效制造能力与长期可靠性验证体系。 据中国光伏行业协会分析，从实际应用看，砷化镓(GaAs)电池凭借高转换效率和优异的抗辐射性能，依然是当前商业航天和空间站的主流选 择，虽然其成本高昂，但经过了长期的在轨验证，可靠性高。 相比之下，资本市场热捧的异质结(HJT)钙钛矿技术，更多是基于个别金融机构自行提出的"降本逻辑"，实际产品目前仍处于实验室或验证 初期，距离大规模商业化尚有距离。 ...
