怒火攻心

A | BEIJING -- China has sent an envoy to the Middle East to push for a cease-fire between Israel and Hamas in the latest sign of its ambition to play a larger role in the region.Envoy Zhai Jun’s first meetings included one in Qatar with a Russian counterpart on Thursday as the two countries stake out a position at odds with the American approach.The two sides confirmed their “unwavering focus on closely coordinating efforts for the political settlement of this and other crises in the Middle East and North Africa region,” Russia’s Foreign Ministry said, according to the country’s Tass state news agency.China, which sees the U.S. as too pro-Israel, has said it opposes attacks on civilians but has not condemned the initial Hamas attack that started the latest war. Instead, it has called for an immediate cease-fire to protect civilians as Israel bombards Gaza before a possible ground invasion.“We believe that when dealing with hot-spot issues in the international community, major powers should be objective and impartial,” Chinese Foreign Ministry spokesperson Mao Ning said Friday.Analysts say that China wants to position itself as a mediator and exert its influence in the region as the U.S. shifts its global attention elsewhere. But the latest Gaza war has drawn the U.S. back in, with President Joe Biden visiting Israel this week. Zhai held meetings in Qatar with Mikhail Bogdanov, the Russian president’s special representative for the Middle East and Africa, and with Qatar’s minister of state for foreign affairs, Mohammed Abdulaziz al-Khulaifi, Mao said.She added that Zhai would travel to other Mideast countries but did not give any details on which ones or when.Egyptian Prime Minister Mostafa Madbouly told Chinese leader Xi Jinping this week that “Egypt and other Arab countries highly appreciate China’s consistent and just position on the Palestinian question and expect China to play a bigger role in solving the current crisis,” according to a Chinese statement on their meeting.Xi told Madbouly, who was in Beijing to attend a forum on China’s Belt and Road infrastructure-building initiative, that the top priority is to stop the fighting and prevent it from causing a severe humanitarian crisis.He said China “stands ready to strengthen coordination with Egypt and other Arab countries to work for a comprehensive, just and enduring solution to the Palestinian question,” the Chinese statement said.。到了USB4，不但再次改变命名方式，技术上也变懒了，几乎直接承袭了Intel捐献的雷电3标准，从物理底层到技术规格都如出一辙。新鲜出炉的USB4 v2.0，也不是接口名字，而只是规范命名。从此以后(到下次再改名)，USB接口将统一以传输带宽命名，USB4 v2.0对应USB 80Gbps，USB4对应USB 40Gbps，USB 3.2 Gen2x2对应20Gbps，USB 3.2 Gen2对应USB 10Gbps，USB 3.2 Gen1对应USB 5Gbps……更古老的USB 2.0、USB 1.0保持不变，因为它们的速度太慢了，还停留在Mbps数量级。

B | 如果改叫USB 480Mbps，不但麻烦还容易引起误会(你也知道容易误会啊)。所以请注意新接口下的包装标识、接口标识、数据线标识：回到UBS4 2.0或者说USB 80Gbps，它的首要变化自然是带宽再次翻番来到了80Gbps，这得益于新的基于PAM3信号编码机制的物理层架构，同时还有新定义的80Gbps有源数据线。在特定应用场景中，比如8K超高清显示，USB 80Gbps还可以配置为非对称编码异步传输模式，一个方向可以高达120Gbps，从而足够承载DP 2.0/2.1 UHBR20信号，另一个方向则是40Gbps。其次，USB 80Gbps升级了数据和显示协议，可以更好地利用带宽，其中数据传输支持20Gbps的高带宽，显示传输则和DP 2.0、PCIe 4.0相互打通，共享PHY物理层，从而一个接口搞定高速数据、显示。当然了，USB 80Gbps依然保持向下兼容，而且只有USB Type-C一种接口形式。
