本周数据平台近期数据平台透露新政策:本月行业协会传递新研究成果,信标:指引迷航者的灯塔
在浩瀚的宇宙中,人类对于导航的需求从未停止过。而在这其中,信标,这一古老的导航工具,扮演着至关重要的角色。从古代的海上航行到现代的航空、航海,信标始终是迷航者心中那座永不熄灭的灯塔。 信标,顾名思义,是一种用于指示方向、定位的标志。它起源于古代,最初用于航海。在茫茫大海中,船只依靠信标来辨别方向,确保航行安全。随着时间的推移,信标逐渐发展成为一种重要的导航工具,广泛应用于各个领域。 在航海领域,信标的作用尤为显著。古代的航海家们,为了找到正确的航线,常常需要依靠星星、太阳等自然标志。然而,这些标志并不总是可靠,尤其在恶劣的天气条件下。于是,人们开始利用信标来指引船只。最早的信标是灯塔,它高耸在海边,发出耀眼的光芒,为船只指引方向。随着科技的发展,信标逐渐从灯塔演变为雷达、无线电等电子设备。 在航空领域,信标同样发挥着重要作用。飞机在飞行过程中,需要依靠地面信标来保持航向。这些信标通常位于机场附近,通过发射无线电信号,为飞机提供导航信息。此外,信标还可以用于飞机的着陆导航,确保飞机安全降落。 除了航海和航空领域,信标在陆地交通、地质勘探等领域也有着广泛应用。在陆地交通中,信标可以用于指示道路方向、提醒驾驶员注意安全。在地质勘探中,信标可以帮助地质工作者确定勘探目标的位置,提高勘探效率。 然而,随着科技的发展,信标这一古老的导航工具也面临着新的挑战。一方面,电子导航设备的普及使得信标的作用逐渐减弱。另一方面,环境因素也对信标的使用造成了一定的影响。例如,雾霾、沙尘暴等恶劣天气条件会干扰信标的信号,导致导航失误。 面对这些挑战,我国科研人员正在积极探索信标技术的创新。一方面,他们致力于提高信标的抗干扰能力,使其在恶劣天气条件下仍能发挥导航作用。另一方面,他们还致力于开发新型信标技术,如激光信标、卫星信标等,以满足不同领域的导航需求。 总之,信标作为一项古老的导航工具,在人类历史上发挥了重要作用。虽然随着科技的发展,信标的作用逐渐减弱,但它在某些领域仍具有不可替代的地位。在未来的发展中,信标技术将继续创新,为人类提供更加精准、可靠的导航服务。 在这个信息爆炸的时代,我们不禁要思考:在科技日新月异的今天,信标这一古老的导航工具是否还能焕发出新的生机?答案是肯定的。正如那座永不熄灭的灯塔,信标将继续指引迷航者前行,为人类探索未知领域提供有力支持。
TMTPOST -- Chinese telecommunications giant Huawei unveiled a sweeping expansion of its artificial intelligence computing ambitions on Thursday, announcing new supercomputing systems powered by its in-house Ascend chips. The move signals escalating competition with U.S. chipmaker Nvidia, the global leader in AI processors.AI-generated imageAt its annual Huawei Connect conference in Shanghai, the company introduced the forthcoming "Atlas 950 SuperCluster," which it said will begin rolling out as early as next year. The announcement underscores Huawei ’ s determination to challenge U.S. dominance in advanced AI hardware despite Washington ’ s tightening export controls on semiconductors."The competition has undeniably arrived and is gaining momentum," an Nvidia spokesperson said. "Customers will choose the best technology stack for running the world ’ s most popular commercial applications and open-source models."U.S. restrictions have cut China off from the most advanced chips needed to train large-scale AI models, forcing Chinese firms to rely on domestically developed processors or stockpiles of older foreign components. Huawei, long targeted by U.S. sanctions, has turned to large-scale clustering of its less powerful but increasingly refined Ascend processors. By combining vast numbers of these chips in interconnected networks, the company aims to match or surpass the performance of systems built on Nvidia ’ s hardware.Huawei said it plans to release three new versions of its Ascend chips through 2028, pledging to double computing power with each iteration. At the base level, its new Atlas 950 supernode will connect 8,192 Ascend chips. A full Atlas 950 SuperCluster would integrate more than 500,000 chips.A future upgrade, the Atlas 960 system slated for 2027, is projected to support nearly 15,500 chips per node and scale to more than 1 million Ascend processors across a full supercluster. Huawei claimed these would represent the world ’ s most powerful AI systems by raw computing power.Huawei did not shy away from comparisons with its American rival. Eric Xu, the company ’ s vice chairman and rotating chairman, said the Atlas 950 supernode would deliver 6.7 times more computing power than Nvidia ’ s upcoming NVL144 system. He went further, predicting Huawei would "be ahead on all fronts" compared with Nvidia ’ s 2027 offering — and claimed the Atlas 950 SuperCluster would even exceed the computing capacity of Elon Musk ’ s xAI Colossus project.While independent verification of Huawei ’ s claims is limited, industry experts said the company ’ s ambition is clear."Huawei ’ s announcement on its computing breakthrough is well timed with recent increasing emphasis by the Chinese government on self-reliance on China ’ s own chip technologies," said George Chen, partner and co-chair of the digital practice at The Asia Group. While noting that Huawei might be overstating its technical edge, he added, "the ambition to be a world AI leader cannot be underestimated."Research from SemiAnalysis earlier this year found that Huawei ’ s CloudMatrix system outperformed Nvidia ’ s equivalent despite each Ascend processor offering only about one-third the power of an Nvidia chip. The advantage came from scale: Huawei deployed roughly five times as many chips in its clusters."Computing power has and will continue to be the key for AI," Xu emphasized during his keynote speech in Shanghai.Huawei ’ s new announcements build on earlier efforts. Two years ago, it introduced the Atlas 900 SuperCluster, which it still markets with "thousands" of Ascend chips. On Thursday, the company said it had already deployed more than 300 Atlas 900 A3 supernodes to over 20 clients across telecoms, manufacturing, and other sectors.This momentum reflects a broader push within China to substitute foreign technology with homegrown alternatives. Beijing has increasingly pressed domestic firms to use local suppliers and invest in national semiconductor capabilities. Huawei ’ s breakthroughs are likely to be touted as proof of progress in these efforts.Huawei ’ s offensive comes as Nvidia faces growing headwinds in China, once one of its most important markets. Earlier this week, China extended an antitrust probe into the U.S. company over alleged monopolistic practices. On Wednesday, Nvidia ’ s shares fell more than 2% after the Financial Times reported that Beijing had ordered Chinese tech giants to halt testing and purchases of the RTX Pro 6000D, one of Nvidia ’ s new AI-focused chips.Nvidia Chief Executive Jensen Huang expressed frustration over the developments. "I am disappointed to hear this news," he told reporters, while reiterating that Huawei represents a "formidable" competitor.The geopolitical context adds another layer of complexity. The U.S. and China concluded trade talks in Spain this week that reportedly included discussions over the fate of TikTok, the video app owned by Beijing-based ByteDance. But technology co
