一 | STOCKHOLM -- A ban on gasoline and diesel-fueled cars from a commercial district of Stockholm's downtown in 2025 will be the first for a European capital, a city official said Thursday.The ban will take effect in a 20-block area of shops, pedestrian walkways and a few homes in order to curb pollution, reduce noise and encourage use of electric vehicles said Lars Strömgren, the city council member for the Greens who's in charge of the Swedish capital's transportation. Many European capitals have restrictions on gasoline and diesel cars, but Strömgren says Stockholm’s complete ban would be a first. “We need to eliminate the harmful exhaust gases from (gasoline) and diesel cars. That’s why we are introducing the most ambitious low-emission zone to date,” Strömgren told The Associated Press. The idea is to create an "environmental zone” where only electric vehicles will be allowed. There will be some exceptions such as for emergency vehicles and transportation for the disabled.In its budget for 2024, the left-leaning, environmentally-focused city council on Tuesday unveiled the plan for the target area just north of the city’s famed Old Town. The municipal government controls a majority in the council, so the vote set for Nov. 23 is expected to be a formality. “We are pretty proud, I must say,” Strömgren said, adding that gradual expansion of the environmental zone would be decided in the first half of 2025.One of the city’s main cab companies, Taxi Stockholm, said its transition to emission-free vehicles is moving at a fast pace. The company’s acting chief executive Pernilla Samuelsson said it's emission-free vehicles now make up 30% of its fleet - almost seven times more than last year. “In other words, the transition is going fast and it is already being driven forward by the industry,” Samuelson said.Some aren't convinced things will go smoothly. Nike Örbrink from the opposition Christian Democrats told the Aftonbladet newspaper that some are concerned the plan would hurt businesses and the hotel industry.Other European capitals harbor similar ambitions. The Dutch capital, Amsterdam, is aiming for all transport in the city, including automobiles, to be emissions-free by 2030.The mayor of Paris wanted to ban all diesel cars before next year’s Olympics, and gasoline cars by 2030, but has run up against resistance.Currently, any diesel cars built before 2006 and gasoline cars built before 1997 are banned in Paris and 77 surrounding towns for 12 hours a day on weekdays. The ban will expand in 2025 for diesel cars built before 2011 and pre-2006 gasoline vehicles.___Jan Olsen reported from Copenhagen, Denmark.

二 | 长期以来，摩尔定律不仅是计算机处理器制造的指导原则，也是促进科技产业自我实现的预言。iPhone、三星Galaxy智能手机和其他设备的常规改进是由摩尔定律决定的。
三 | 然而，当芯片元件的尺寸接近单个原子的尺寸时，要跟上摩尔定律就变得越来越困难。现在，每两年将特定芯片上的晶体管数量和相应的处理能力翻一番，变得越来越昂贵，技术上也越来越困难。黄仁勋在展览会上指出：“摩尔定律过去每五年增长10次，每十年增长100次。现在摩尔定律一年只能增长几个百分点。也许每10年只有两次。摩尔定律结束了。
四 | 这不是黄仁勋第一次宣布摩尔定律的终结。他在过去几年里也发表过类似的言论。技术产业关注的是，一旦半导体发展放缓，整个电子创新也将放缓。处理器的收缩提高了电池寿命，降低了成本，提高了设备性能。长期以来，英特尔一直是半导体制造业的领导者。它已经多次推迟了向10纳米制造业转移的计划，而三星等其他公司也在引进更先进的7纳米芯片。尽管像黄仁勋这样的人已经宣布摩尔定律的终结，材料科学家仍在寻找改善现有硅晶体管技术的方法，并正在探索替代技术，如超薄碳石墨烯片。市场研究公司Moor Insights。
