China unveils refined lunar map, empowering future moon exploration_我的网站

A |     日前韩媒报道称，台积电再度将3纳米芯片量产时程延后三个月。    A Chinese research team has completed an updated geologic map of the entire moon featuring a scale of 1:5 million, the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS), said on Thursday.    Representing a significant scientific iteration from the 2024 version, this map effectively rewrites the moon's geologic history based on the latest research findings. "The lunar geologic history has indeed been rewritten -- more precisely, refined and systematized," said Yang Zhiming, director of the IGCAGS.    Specifically, a primary achievement of this update is the recalibration of the moon's ancient geologic eras. The new map systematically updates the age boundaries of the moon's three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology.    Crucially, Chang'e-5 samples confirmed volcanic activity on the moon as recently as 2 billion years ago, extending its geologic lifespan by 1 billion years from the previously accepted 3 billion years. This independent dating data has now become a cornerstone of the global lunar geologic timescale.    Highlighting these spatial discoveries, the new global lunar geologic map is the first comprehensive canvas to bear exclusive findings from the Chang'e-6 mission. "The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side," said Jin Ming, an associate researcher at the IGCAGS.    The map details the age of young mare basalts on the lunar far side obtained from the Chang'e-6 samples, recording the region's volcanic history. Furthermore, it reveals that KREEP rocks, enriched with rare earth elements and other strategic resources, are far more continuous and abundant in the Oceanus Procellarum than previously estimated. This discovery, achieved by eliminating spectral noise, prompts a systemic reevaluation of the moon's early magma ocean crystallization and internal thermal evolution.    Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard. Identifying over 13,500 impact craters and 81 basins, it employs a unique color scheme rooted in geologic logic and traditional Chinese aesthetics, following a "lighter for younger, darker for older" principle.    Furthermore, this standard will also be applied to future geologic mapping of Mars and asteroids, ending reliance on foreign standard systems.    "This goes beyond showcasing technological soft power. This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China's deep space exploration," Yang said.                    。对此，台积电表示，3纳米制程的发展符合预期，良率高，将在第4季稍后量产。

B | 据台媒《经济日报》报道，业界人士指出，韩媒之所以用“再度延后”的字眼，应与台积电最初释出“3纳米预计2022年下半年量产”的说法有关，韩媒可能认为“2022年下半年”指的是7月。此前台积电总裁魏哲家在第三季度法说会上表示，客户对3纳米的需求超越台积电的供应量，明年将满载生产。台积电正与设备供应商紧密合作，为3纳米制程准备更多产能，以支持客户在明年、2024年及未来的强劲需求。
