稀土，这个听起来有点"土"的名字，却在全球科技产业中扮演着"黄金"般的角色。中国掌握着全球80% 以上的稀土供应，这看似是一张王牌，但为什么专家们都说"稀土牌"只能打一次？让我们揭开这背后的 国际博弈密码。 稀土到底有多重要？ 从智能手机到电动汽车，从战斗机到风力发电机，稀土元素无处不在。钕铁硼永磁体让手机振动马达能 如此小巧，镧系元素让LED屏幕色彩如此鲜艳。没有稀土，现代科技将倒退20年。这就是为什么各国对 稀土资源如此紧张，中国在稀土领域的优势地位让西方国家寝食难安。 但问题来了——为什么我们不多用几次这张王牌？答案藏在全球供应链的复杂棋局中。过度使用稀土武 器会引发连锁反应，刺激其他国家加速开发替代资源和技术。就像打扑克时亮出底牌后，对手就会找到 破解之道。 国际博弈如同下棋，最厉害的玩家不是靠一两个杀招取胜，而是通过全盘布局建立持久优势。稀土这张 牌，要用在刀刃上，用在最能改变游戏规则的时刻。毕竟，真正的强者不是拥有最多牌的人，而是最会 打牌的人。 稀土禁运的历史教训 稀土的真正价值在哪里？ 2010年，中国对日本实施稀土出口限制，引发全球震动。这一举措确实让日本企业措手不及，但也催生 了全球稀土供 ...

宋肇南（右）和同事正在检查设备。 上午刚过8时，首钢极限公园就迎来了第一位"客人"。从随身携带的工具箱中掏出钳型卡表，宋肇南对 LED屏幕电路设备进行"体检"。"数据一切正常，没问题！"他起身抬头仰望，LED屏点亮了，开始循环 播放WTT赛事宣传片。他一天的工作，也拉开序幕。 宋肇南来自首钢体育公司，负责极限公园、冰球馆、大跳台等场馆的能源电力保障工作。这个国庆中秋 假期园区举办WTT、糖果季等活动，他和同事更加繁忙，每日坚守一线，做到"服务无死角、保障无盲 区"。收拾好工具后，宋肇南并没有着急离开，他从各个角度仔细观察大屏幕播放效果。 9时许，园区人气渐旺，多数游客直奔滑雪大跳台区域，奔赴大满贯公园或糖果季街区。宋肇南不由自 主加快脚步，再次开启"火眼金睛"模式。走进糖果季场馆，只见游客正有说有笑地选购商品，他径直走 到幕后工作区，对所有电箱逐一检测，又来到各个展位前查看用电情况。到了夜间，宋肇南更加繁忙， 要确保用电高峰期的安全保障工作万无一失。这个假期，他每天都要工作到WTT比赛结束后，晚10时 完成最后一次巡检后才能下班。 宋肇南在首钢工作了近30年，之前在老厂区就从事电力工作。现如今，他的工作跟随着 ...
