深层海相钾盐开发关键技术被攻克
Huan Qiu Wang Zi Xun· 2026-02-05 01:45
"深层海相钾盐埋藏深、赋存条件复杂,常规开采技术难以实现资源高效分离利用,曾长期被视为难以 动用的呆矿。"四川巴人恒创钾盐有限公司总工程师贾晓华说,"而今困扰行业20余年的难题终于被破 解,我们提取出的钾盐品质与纯度均达到高标准要求。" 科研团队提出,基于"新型杂卤石钾盐矿"可溶性的特点,可以直接采用水溶法进行溶采:打对接井,淡 水从中间的直井注入,沿水平井段溶解地下"新型杂卤石钾盐矿",在注水压力和地层压力的共同作用 下,溶矿卤水和天然卤水会从两侧的对接井涌出。 来源:光明日报 本报达州2月4日电(记者李晓东、周洪双) 近日,四川达州宣汉县深层海相钾盐资源分采分运攻关实验配套装置顺利完成试车,成功提取出高纯度 氯化钾产品。这标志着我国在深层海相钾盐开发领域攻克核心技术瓶颈,为亿吨级海相钾盐资源规模化 开发筑牢技术根基。 钾盐是重要的矿产资源,主要用于生产钾肥。近年来,我国钾盐对外依存度达43%~67%。 此前,国内钾盐开发主要集中于青海、新疆的陆相盐湖,四川达州宣汉县发现的全国首个海相富锂钾资 源矿,圈定"新型杂卤石钾盐矿"富矿区面积达179平方千米,估算推断资源量超7.1亿吨,推算可采储量 约2.45亿吨 ...
两枚足迹揭秘侏罗纪两栖动物世界

来源:光明日报 e 研究团队透露,这一化石的最初发现者,是当时就读于北京市第二实验小学德胜校区、年仅12岁的化石 爱好者倪景辰。2025年1月11日,在北京市门头沟区九龙路森林保护站附近的山坡出露岩层上,倪景辰 与父母偶然注意到该化石。倪景辰回忆:"由于风化严重,我在现场只注意到了一枚足迹化石,有很明 显的四趾痕迹。" 面对如此微小的四足动物足迹,首要问题是确定造迹者的类别。研究团队整理了来自21篇文献的24件中 生代蝾螈化石标本的前后肢骨骼数据,对36幅骨骼照片和线描图进行定量测量,构建出规范化的指骨比 例数据库。 "为消除不同物种和个体体形差异的影响,研究人员采用最长指归一化的方法,对各指长度比例进行统 计分析,并完成数据处理和箱线图可视化。"邢立达表示。 "该区域因富含侏罗纪植物化石而长期吸引着化石爱好者。2023年夏季暴雨导致的山体滑坡,使更多岩 层得以暴露,为这次偶然却关键的发现创造了条件。"研究团队主要成员、中国地质大学(北京)地球 科学与资源学院副教授邢立达分析。 倪景辰随后将此发现发表在社交媒体上,引起了邢立达的关注。2025年6月,研究团队在倪景辰的带领 下到现场考察确认,发现化石产自一套黄 ...

Core Viewpoint - The "Artemis 2" manned lunar mission by NASA has been delayed again due to a hydrogen leak detected during a wet dress rehearsal of the Space Launch System (SLS) rocket, pushing the launch date from February 8 to March [1][3]. Group 1: Mission Details - The "Artemis 2" mission is crucial as it aims to send astronauts to the Moon using the SLS rocket and the Orion spacecraft [5]. - The mission is expected to set a new record for the farthest distance from Earth achieved by humans, while also laying the groundwork for the subsequent "Artemis 3" mission [5]. Group 2: Technical Issues - During the wet dress rehearsal, over 700,000 gallons of cryogenic fuel were injected into the SLS rocket, but a hydrogen leak was detected, leading to the suspension of fueling operations [3][4]. - The leak was identified in the cavity between the umbilical plate and the rocket, causing the fueling process to be interrupted multiple times [4]. - The repair of the hydrogen leak is complex, requiring testing under the same conditions as the launch day, which can only be conducted at the launch pad [4]. Group 3: Future Plans - NASA plans to conduct another wet dress rehearsal to address the hydrogen leak and complete the remaining objectives that were not achieved in the first rehearsal [5]. - Potential new launch windows are set for March 6, 7, 8, 9, and 11, contingent on the resolution of the current issues [5].
AI能否像艺术天才那样去创作
Huan Qiu Wang Zi Xun· 2026-02-04 10:38
来源:光明日报 随着AI(人工智能)工具的大量涌现及不断迭代,艺术创作的门槛大大降低。进入AI艺术创作平台, 输入一段简单的提示词,短短几秒钟,便可创作出诗歌、图片、视频等不同类型的作品。不过,观察对 比大量的AI作品后会发现,这些作品高度同质化,自然传神、新颖独创的作品非常稀缺——这已经是 人们的共识。AI艺术创作有没有可能像人类艺术创作那样迸发出灵感的火花?笔者认为,AI艺术创作 要想突破同质化,须从算法创新、模型构建以及用户素养培养等方面协同发力。 从提示词撰写到作品遴选修改,构建提升作品独创性的机制 中国传统画论中有一个至高标准曰"传神",顾恺之讲"传神写照",谢赫讲"气韵生动",这些观点都在强 调同一个道理:艺术不是对物理表象的机械复刻,而是对生命内在精神和世界本质的揭示。 当下的AI艺术创作,面临的一大困境是擅长"写形",却不擅长"传神"。要理解这一困境,必须回到艺术 创作的逻辑原点。郑板桥曾精辟地将画竹的过程概括为三个阶段,即"眼中之竹""胸中之竹""笔中之 竹"。"眼中之竹"是艺术家深入生活、体验万物,通过感性认识直观获取的生活真实;"胸中之竹"是艺 术家经过审美情感的浸润、过滤、重构与升华形 ...
