摘　　要：激光驱动惯性约束聚变有望解决能源危机,但聚变过程条件的苛刻性对在其中充当靶丸材料的空心微球的品质,如球形度、壁厚均匀性、表面粗糙度、壳层材料密度等提出了严格要求,而制备方法的选择及条件控制直接影响到微球的上述性能。本工作主要综述了研究较为广泛的炉内成球技术、降解芯轴技术以及乳液法的制备过程、适用范围、优劣势等,并对乳液法的形成机理和影响因素进行了较详细的阐释。Inertial confinement fusion is a promising approach to solve energy crisis.The rigorous prerequisites in fusion require hollow microspheres that act as targets with some special criteria(i.e.,sphericity,uniform thickness and density of shells,and surface coarseness).These properties are directly related to the preparation methods and operation conditions.In this review,some existing preparation methods(i.e.,drop-tower technology,degrading mandrel technology and microemulsion method)were mainly described.Their process,application range,advantages and disadvantages were analyzed,especially for the formation principles and influencing factors of microemulsion method.This review could provide a reference for future fabrication of targets with a higher quality.
