刚刚科研委员会公布突破成果:昨日行业协会传递行业新动态,久久一码、二码、三码的区别及应用解析

随着互联网技术的飞速发展，二维码作为一种便捷的信息传递方式，已经广泛应用于各个领域。在众多二维码中，久久一码、二码、三码因其独特的功能和特点，备受关注。那么，它们之间有什么区别呢？本文将为您详细解析。 ### 一、久久一码 久久一码，顾名思义，是指一个二维码中只包含一个信息点。这种二维码通常用于展示简单的信息，如网址、联系方式等。其特点如下： 1. **信息量小**：由于只包含一个信息点，久久一码的信息量相对较小，适合展示简单的信息。 2. **生成简单**：制作久久一码的过程相对简单，只需选择合适的二维码生成工具，输入信息即可生成。 3. **应用场景广泛**：久久一码适用于各种场景，如名片、宣传单、产品包装等。 ### 二、久久二码 久久二码，即一个二维码中包含两个信息点。相较于久久一码，久久二码的信息量更大，功能更丰富。其特点如下： 1. **信息量大**：久久二码可以包含两个信息点，如网址和联系方式，满足用户多样化的需求。 2. **功能丰富**：除了展示信息外，久久二码还可以实现一键拨打电话、发送短信等功能。 3. **应用场景多样化**：久久二码适用于产品宣传、活动推广、企业名片等场景。 ### 三、久久三码 久久三码，即一个二维码中包含三个信息点。相较于久久二码，久久三码的信息量更大，功能更加全面。其特点如下： 1. **信息量丰富**：久久三码可以包含三个信息点，如网址、联系方式和产品介绍，为用户提供更全面的信息。 2. **功能全面**：除了展示信息外，久久三码还可以实现一键拨打电话、发送短信、导航等功能。 3. **应用场景广泛**：久久三码适用于企业宣传、产品推广、活动策划等场景。 ### 四、区别总结 1. **信息量**：久久一码信息量最小，久久三码信息量最大。 2. **功能**：久久一码功能单一，久久三码功能最全面。 3. **应用场景**：久久一码适用于简单的信息展示，久久三码适用于多样化的应用场景。 ### 五、选择建议 在选择久久一码、二码、三码时，应根据实际需求进行选择。以下是一些建议： 1. 如果只需要展示简单的信息，如网址、联系方式等，可以选择久久一码。 2. 如果需要展示更多信息，如网址、联系方式、产品介绍等，可以选择久久二码。 3. 如果需要实现更多功能，如一键拨打电话、发送短信、导航等，可以选择久久三码。 总之，久久一码、二码、三码各有特点，适用于不同的场景。了解它们之间的区别，有助于我们更好地选择合适的二维码，提高信息传递的效率和效果。

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
