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

一 |     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.                    。    　　北京8月25日电 (记者 郭超凯 张素)企业破产法修订草案二次审议稿25日提请十四届全国人大常委会第二十四次会议审议。　　修订草案规定，破产申请提出后至人民法院受理前，债务人的财产存在贬值或者被恶意转移等紧急情况的，当事人可以申请人民法院采取中止执行或者保全措施；必要时，人民法院可以要求当事人提供担保。　　有的地方、单位和专家建议，借鉴一些国家的做法，明确在破产申请审查期间人民法院可以决定对债务人财产给予临时保护，以保证破产程序有序进行。

二 | 　　对此，修订草案二审稿明确，申请人提出破产申请后至人民法院作出裁定前，债务人、债权人可以申请人民法院临时中止有关债务人财产的执行程序；临时中止执行期间，未经人民法院同意，债务人不得对个别债权人进行清偿，不得实施重大财产处分行为。　　此外，为明确本法的域外效力，完善我国法院对跨国破产案件管辖权等规定，修订草案二审稿作出修改。

三 | 其中，恢复现行法的规定，明确依照本法开始的破产程序，对债务人在我国领域外的财产发生效力。　　修订草案二审稿还增加规定，债务人住所地位于我国领域外，但财产位于我国领域内或者与我国存在其他适当联系，或者由我国法院管辖更有利于保护债权人利益的，我国法院可以行使管辖权。
