本报记者 徐 靖 "杜瓦底座是紧凑型聚变能实验装置主机的首个真空大部件，设计工况复杂，接口有数百个；结构尺寸 大，直径约18米，高约5米，重400余吨，是紧凑型聚变能实验装置主机系统中最重的部件。"郑磊说， 虽然是个"大家伙"，但它的吊装精度极高，表面水平高差需控制在15毫米以内，落位位置偏差不得超过 正负2毫米；作业空间极度狭小，底座外边缘与主机坑屏蔽墙的最小间隙不足100毫米。 中国科学院合肥物质科学研究院等离子体物理研究所副研究员黄雄一介绍："杜瓦底座的安装完成，标 志着大部件的安装即将开始。随后，像磁体、真空室等重要部件将安装在杜瓦底座上。最终，我们会把 杜瓦底座封闭起来，形成一个真空环境来确保托卡马克装置的运行。" "之所以建设紧凑型聚变能实验装置，一方面，经过多年对'东方超环'的研究，我们逐渐摸清了相关原 理；另一方面，在聚变堆主机关键系统综合研究设施'夸父'的研发过程中，我们逐渐突破了一系列技术 和工程方面的瓶颈。"郑磊说，"未来真正建设聚变堆，还需要进一步探索。为此，我们要进一步建设属 于我们自己的聚变能实验装置。" 紧凑型聚变能实验装置能够提供接近未来聚变堆参数的集成环境，为聚变示范电站建设 ...

这一发现不仅挑战了人们对螺旋桨推进方式的传统认知，也对微型医疗机器人、管道检测设备等应用具 有重要意义。"一些微型设备通常只有几毫米大小，传统螺旋桨推进装置可能失效，要研究如何调整参 数，来抑制或利用这种离心吸力。"丁阳说。 《 人民日报 》( 2025年10月19日 05 版) 本报电 (付蓉)近日，北京邮电大学丁阳教授团队在著名学术期刊《美国国家科学院院刊》发表研究成 果，首次发现螺旋桨在特定尺度流体环境中出现的"推进力反转"现象，并对此进行了系统阐释。 研究发现，在毫米至亚毫米尺度下，顺时针旋转的螺旋桨不仅不会使微型潜艇向前推进，反而会使其向 后运动。"像是螺旋桨在吸着自己往后走，而不是推着向前。"丁阳介绍，物体在不同雷诺数环境下表现 出截然不同的运动特性。普通尺度下，螺旋桨通过向后推水产生向前的推力；而毫米至亚毫米尺度下， 螺旋桨旋转时，原本应该向后喷射的水流被偏折向四周，像一个小型离心水泵，把周围的液体往外甩 开，反而在螺旋桨中心形成吸力，这种吸力把潜艇拉向反方向。 ...

当一尾尾中华鲟游向长江，这不仅是一个物种的延续，更是人与自然和谐相处的历史性转变。这条生态 优先、绿色发展的新路，正随着长江的波涛奔腾向前，为子孙后代留下一条充满生机的大河。 从"保护单一物种"向"保护生境系统"的转变，标志着生物多样性保护理念的重要升级。长江生态保护是 一项系统工程，需要多措并举、协同发力。在活体保护层面，总投资2800万元的三峡珍稀特有水生动物 种质资源库活体库，已保育包括中华鲟、长江鲟在内的18种珍稀特有物种，数量达6800余尾，形成了珍 贵的"活体基因库"；在遗传资源保存方面，"三峡遗传资源保存库"构建了从标本、组织、细胞到核酸的 全链条保藏体系，为物种保护保留了完整的遗传资源。从系统角度出发，提升长江流域水生生物多样性 的整体水平，真正实现生态系统的稳定和恢复。 系统推进，探索生态治理新路径，为人水和谐谱写时代新篇。生态保护非一朝一夕之功，需要久久为功 的韧劲。水利部长江水利委员会连续15年开展三峡工程生态调度试验，通过模拟自然水文过程，促进了 四大家鱼等产漂流性卵鱼类的自然繁殖。水生态所自2022年以来，已累计为长江沿线放流7万余尾中华 鲟鱼苗。长江流域生态修复是一项长期而复杂的系 ...

晨光中的庐山西海，几座屋舍静立水畔，构成一幅水墨画般的静谧图景。人民网记者 邱烨摄 10月7日清晨8点，武宁县渡头村村民尹彬手持长柄夹，沿着湖岸缓缓巡查，一个被晨露打湿的纸杯应声落入 环保袋中——这位在庐山西海漂泊数十年的捕鱼人，洗脚上岸，成为了村里度假区的后勤管理负责人。 夕阳西下，湖面泛起粼粼金波。稍微闲下来的尹彬，向记者算起了"新生活的账"："每月有固定工资，年底能 拿入股分红，老宅出租还有租金，一年下来比以前打鱼挣得还多！"尹彬眼角的皱纹里，满是日子越过越红火的欣 慰。 渡头村，南依植被茂密的九岭山脉、北临水域面积308平方公里的庐山西海，村民大多以捕鱼为生，是一个传 统渔村。2020年，为积极响应长江"十年禁渔"决策部署，庐山西海水域全面实施禁捕退捕。 "不打鱼了，日子怎么过？"彼时，全面禁捕的消息令尹彬辗转难眠。"除了休渔期，天天在水上忙活，一年能 挣十来万元。"他把"退捕上岸"的账翻来覆去算，怎么算都觉得"亏"——捕鱼是他干了大半辈子的营生，也是全家 主要的收入来源，放下渔网，就像丢了"饭碗"。 后几年，尹彬在县城打零工、接短活，收入远不如前，对未来也充满迷茫。转折发生在2024年春天，渡头 村 ...
