我国嫦娥六号样品和“月壤砖”研究取得新进展
Yang Shi Wang· 2025-11-25 12:19
央视网消息(新闻联播):记者从中国科学院地质地球所获悉,通过对嫦娥六号月球样品研究分析,我国科研团队成功破解了月球背面月壤的"黏性之谜"。 相较于月球正面的月壤,背面月壤的颗粒形态更复杂,表面更粗糙,显著增大了颗粒间的摩擦效应,使得分子间作用力、静电力等作用凸显,造成月壤样品 表现出明显的黏性特征。 近日,由华中科技大学团队研制的模拟"月壤砖"也取得新进展。初步研究发现,历经一年太空暴露、大温差等极端环境考验,模拟"月壤砖"状态良好。据了 解,科研团队将通过为期三年的模拟"月壤砖"太空实验,为月球的探测和基地建造积累重要数据。 ...
