摘　　要：玻璃是最古老也是现代应用最广的材料之一,列属于非晶态物质,组成单元的无序排列致使其物理本质、物性的内涵以及性能优化等依旧是当代材料、物理和化学学科研究热点和难点。作为新型合金材料和玻璃,金属玻璃,特别是块体金属玻璃,尽管出现较晚,但因具有重要潜在应用价值和基础理论研究意义,一经出现就受到了广泛关注。微重力条件下块体金属玻璃研究不仅促进了玻璃形成机理、液体热力学特征、过冷液体动力学行为以及深过冷液体形核与长大等等长期存在的基础理论问题研究,也推动着此类材料的实际应用。在梳理了过去30年来国内外块体金属玻璃微重力条件下研究进展的基础上,对于未来国内块体金属玻璃微重力条件下的研究进行了展望。Glass is one of the oldest and the most widely used materials in modern times. It belongs to the amorphousmaterial. The disordered arrangement of the components makes its physical essence,physical properties and optimization still remain the hot topics and difficulties in materials science,physics and chemistry. As a new material and glass,metallic glass, especially bulk metallic glass,although its appearance is late,has receiattention due to its important potential application value and basic theoretical research significance. Microgravity research of bulk metallic glass not only promotes the clarification of fundamental issues,such as liquid thermodynamicliquid dynamics and nucleation and growth in supercooled liquid etc.,but also improves the application of this kind ofmaterials. Based on the review of the research progress of bulk metallic glass under microgravity in the past thirty yearpaper prospected domestic research in the future.
