在地面重力条件下与流体相关的材料制备过程中,重力引起的对流、沉降和器壁效应等将不可避免的影响材料质量。通过在多功能炉中的空间材料实验,攻克在地面条件下材料制备中无法解决的难题,获得在地面无法得到的高性能优质材料,开发新的材料制备工艺。另一方面,通过天地对比研究,揭示材料制备过程中的微观机理和组分、结构与性 During the preparation of fluid-related materials under the conditions of gravity on the ground, gravity-induced convection, settlement and wall effects will inevitably affect the material quality. Through the experiment of space materials in multifunctional furnaces, we can overcome the unsolvable problems in the preparation of materials under the ground conditions and obtain high-performance and high-quality materials that can not be obtained on the ground and develop new material preparation technology. On the other hand, through the comparative study of heaven and earth, revealing the microscopic mechanism and composition, structure and nature
