本报北京5月22日电在北京时间21日晚结束的2023年国际篮联三人篮球女子系列赛阿斯塔拉站上，中国队以21∶15战胜埃及队获得冠军。中国队就此包揽今年该项赛事前两站冠军。

国际篮联三人篮球女子系列赛是三人篮球女子项目最高级别的职业赛事，本赛季赛事计划举办21站比赛。

据悉，到2023年11月1日，国际篮联积分前三的球队将直接获得巴黎奥运会参赛资格。中国队将于5月底参加维也纳三人篮球世界杯，争取更多积分。(记者王亮)

　　　　从某种意义上说，加拿大个别政客和媒体对所谓“中方干涉加内政”的炒作是失败的。尽管有加情报部门不断炮制虚假报告进行精准投喂，这几个政客和媒体也非常卖力，但就一个话题渲染炒作了几个月时间，仍然未能在加拿大掀起他们期待中的风浪。其中的关键在于他们始终拿不出有说服力的真凭实据，而加拿大多数民众也不像他们以为的那么好糊弄。≮爱过伤过悔过哭过≯ぷ￠◎ㄨ○搞基的(<)【<】(p)【p】(>)【>】(记)【ji】(者)【zhe】(5)【5】(月)【yue】(2)【2】(2)【2】(日)【ri】(从)【cong】(第)【di】(二)【er】(次)【ci】(青)【qing】(藏)【zang】(高)【gao】(原)【yuan】(综)【zong】(合)【he】(科)【ke】(学)【xue】(考)【kao】(察)【cha】(研)【yan】(究)【jiu】(队)【dui】(获)【huo】(悉)【xi】(，)【，】(2)【2】(0)【0】(2)【2】(3)【3】(年)【nian】(珠)【zhu】(穆)【mu】(朗)【lang】(玛)【ma】(峰)【feng】(极)【ji】(高)【gao】(海)【hai】(拔)【ba】(地)【di】(区)【qu】(综)【zong】(合)【he】(科)【ke】(学)【xue】(考)【kao】(察)【cha】(研)【yan】(究)【jiu】(正)【zheng】(在)【zai】(西)【xi】(藏)【zang】(珠)【zhu】(峰)【feng】(地)【di】(区)【qu】(开)【kai】(展)【zhan】(，)【，】(来)【lai】(自)【zi】(5)【5】(支)【zhi】(科)【ke】(考)【kao】(分)【fen】(队)【dui】(1)【1】(3)【3】(支)【zhi】(科)【ke】(考)【kao】(小)【xiao】(组)【zu】(的)【de】(1)【1】(7)【7】(0)【0】(名)【ming】(科)【ke】(考)【kao】(队)【dui】(员)【yuan】(，)【，】(将)【jiang】(继)【ji】(续)【xu】(聚)【ju】(焦)【jiao】(水)【shui】(、)【、】(生)【sheng】(态)【tai】(、)【、】(人)【ren】(类)【lei】(活)【huo】(动)【dong】(，)【，】(揭)【jie】(示)【shi】(青)【qing】(藏)【zang】(高)【gao】(原)【yuan】(地)【di】(球)【qiu】(系)【xi】(统)【tong】(变)【bian】(化)【hua】(机)【ji】(理)【li】(，)【，】(优)【you】(化)【hua】(青)【qing】(藏)【zang】(高)【gao】(原)【yuan】(生)【sheng】(态)【tai】(安)【an】(全)【quan】(屏)【ping】(障)【zhang】(体)【ti】(系)【xi】(。)【。】(新)【xin】(华)【hua】(社)【she】(记)【ji】(者)【zhe】(孙)【sun】(非)【fei】(摄)【she】(<)【<】(/)【/】(p)【p】(>)【>】

5月23日12时30分许，2023年珠峰科考13名登顶队员成功登顶地球之巅珠穆朗玛峰。之后，他们将完成峰顶雪冰样品采集等重要科考任务。新华社特约记者拉巴摄

新华社拉萨5月23日电（记者曹槟、陈尚才、田金文）23日，肩负2023年珠峰科考使命的13名科考登顶队员成功登顶珠穆朗玛峰。人类首次登顶珠峰70周年之际，中国珠峰科考继2022年之后再次突破8000米以上海拔高度。

当日凌晨3时，科考队员从海拔8300米的突击营地出发，历经8小时攀登，抵达海拔8830米的世界海拔最高自动气象观测站点，并完成气象站零部件升级的全部工作。

12时30分许，所有科考队员顺利攀登至海拔8848.86米的珠峰峰顶，采集雪冰样品，用于大气污染物、特别是新型污染物的观测等研究。

2023年珠峰地区综合考察研究是第二次青藏高原综合科学考察研究的一部分。自4月底以来，来自5支科考分队13支科考小组的170名科考队员，聚焦水、生态和人类活动，在珠峰及其附近地区开展多项科考研究。

“今年科考具有更大的学科涵盖面，仪器设备也更加高端，特别是和探月工程合作创新的新型电池，为峰顶极端环境仪器设备运行提供可靠能源供应。”2023年珠峰科考现场总指挥安宝晟说。

“自动气象观测站维护升级，重点考虑了极端环境下电池续航问题，在海拔6500米以下新增降水量观测，以获取更全面的梯度气象观测资料。”中国科学院青藏高原研究所研究员赵华标说。

处在地球之巅的珠峰地区是感知全球气候变化的前哨。中科院西北生态环境资源研究院副院长康世昌说，雪冰样品将为了解珠峰地区气候变化历史提供丰富的信息。

“青藏高原气候环境变化与世界其他地区紧密相连。”第二次青藏高原综合科学考察研究队队长、中科院院士姚檀栋说，“极目一号”ⅲ型浮空艇等系列先进仪器的使用，有力提升了观测精度和探测水平。

近年来，珠峰科考不断取得新突破：架设世界海拔最高的自动气象站，利用直升机和浮空艇新平台首次对珠峰地区二氧化碳、甲烷的垂直分布进行测量……

“珠峰科考已实现从‘我要征服你’到‘我要了解你’的思路转变。”姚檀栋表示，中国在冰川变化、气候变化、生态变迁等领域的科学研究，已在国际上处于第一方阵。

“2023年珠峰科考是第二次青藏科考不断拓展广度和深度的重要内容，相信越来越多的‘未解密码’将被‘破译’。”科技部副部长、第二次青藏科考领导小组办公室主任李萌说。

　　　　北京联合大学台湾研究院副院长 李振广：这毫无疑问是美国要把台湾打造成“豪猪”，就是在军事上帮助台湾当局“拒统”，全面武装台湾。但是美国军火商生产能力上有很大的欠缺，在这种情况下，美台就想在台湾设立一些合作的兵工厂，生产一些器械弹药装备之类。据了解，美台这种合作主要是要生产无人机和一些弹药，台湾地区生产无人机有它先天的优势，比方说它芯片生产在世界领先。基础的弹药让美国生产很不现实，因为毕竟美国离得很远，把弹药生产好以后再运到台湾，费时费力，所以说他们想把一些基础弹药也放在台湾来生产，当然能不能成还要看。

长期以来，东风公司始终坚持科技自立自强，坚持自主掌握核心技术，在“东方风起”计划和科技创新“跃迁行动”的指引下，东风公司已实现手册中多个领域科技创新成果的产业化应用。在半导体领域，东风与中国中车联合研发的igbt模块，具备技术、成本双优势，已形成年产30万套的规模，并将在未来三年达到100万套的年生产力。不仅如此，在满足东风企业内部需求同时，东风公司已向行业头部企业规模化供货；在动力领域，东风在燃气喷射系统、涡轮增压器、发动机整体等方面都拥有技术优势，其中，马赫动力c15tdr发动机是东风最新一代1.5l增压直喷发动机，包含13项行业领先技术，且其中4项技术为行业首次量产应用，不仅能适配传统燃油车型，还能适配hev/phev/rev混动车型，目前已面向行业提供产品和技术服务，实现6款车型投放市场；在自动驾驶领域，东风无人驾驶乘用车robotaxi、5g自动驾驶汽车以及sharing-van开发均达到了l4级水平，并已在全国多个城市开展示范运营，robotaxi累计运行里程已经超过200万公里，东风第一个参与雄安新区智慧交通和智慧城市建设，首批20台东风l4级无人驾驶共享巴士（sharing-bus）已在雄安新区开展示范运营。

手册收录的多项成果，是东风公司加速向卓越科技企业转型的“助推器”。面向未来，东风将坚持关键核心技术攻坚，提升科技创新实力和创新成果产业化应用能力，加快产品迭代升级，为行业提供更多更优质的产品和服务，推动汽车产业转型升级，助力实现由中国制造向中国创造迈进的跨越式发展。

直升机依次起飞。齐东摄

大角度规避、大幅度跃升……初夏时节，崇山峻岭间，第79集团军某陆航旅数架直升机隐蔽突防。飞行员们操纵战机俯仰盘旋，突破性能边界，规避“敌”雷达探测和防空火力打击，完成超低空突防任务。

“只有在平时训练中主动探索极限性能、处置极端情况、应对极难特情，才能在作战应敌时有效化解各种困局、险局、危局。”该旅领导说，未来战场上，敌我双方对抗更加激烈、环境更加多变、情况更加复杂，只有平时做到不畏艰险、勇于突破，才能锻造能打胜仗的过硬队伍。

据了解，该旅根据任务需求和作战环境特点，大胆开展临界点飞行训练，鼓励飞行员勇拓“飞行边界”。一次次训练中，他们飞出极限坡度、逼近极限高度、运载极限重量，逐渐突破战斗力生成“天花板”；以复杂气象、陌生空域为“磨刀石”，借助风向风速多变、气流气压不稳等复杂条件，连贯组织低空突防、伴随掩护、悬停起降等课目训练，倒逼飞行员挑战极限，全面锤炼飞行员实战能力。

一次，该旅组织低能见度山区飞行训练。面对突发情况，长机机长杨晓峰迅速拉杆跃升。随着仰角幅度加大，战机受气流影响剧烈颠簸，杨晓峰凭借丰富飞行经验迅速稳住战机。紧接着，他采取山谷绕飞、低空突进等方式隐蔽机动，顺利完成突防任务。

“面对险难课目，只有找准方法、敢于突破，才能有效控制风险，实现能力跃升。”走下战机，杨晓峰深有感触地说。

勇拓“飞行边界”，让每一次飞行都成为战斗力提升之旅。近日，该旅组织千里机动演练。飞行员驾机连续作战，飞跨高海拔、低含氧量地区，积累了数百项恶劣环境条件下飞行数据，检验了前期总结的战术战法，在实战化训练中不断推进战训耦合。（杨心柳海洋）
