摘　　要：根据准球型负载的结构和材料特点及其装配过程中对精度的要求,开展了丝阵和泡沫微球装配技术的研究。并根据准球型负载的丝阵装配技术,进行了丝阵直径约8mm、钨丝直径约10μm的丝阵负载装配;利用泡沫微球装配系统进行了直径约3mm微球与直径约200μm玻璃纤维的精确装配。准球型负载已成功应用于准球型负载物理试验中,并取得了较为理想的试验结果,有望在惯性约束聚变(ICF)物理试验及准球型负载物理试验中发挥更大的作用。Based on the structural and material characteristics and requirements of the accuracy of quasi-spherical load in the process of assembly, the study on the assembly process of microspheres and wire array was carried out. And according to the assembly process of wire array, we finished the assembly of wire array with 8 mm diameter, and tungsten wire with 10 μm diame ter; the assembly of a micro ball with 3 mm diameter and glass fiber with 200μm diameter was performed on a foam microsphere micro-assembly system. Quasi-spherical load was successfully applied in physical tests of quasi-spherical load, and satisfactory results were achieved. It is expected to play a greater role in inertial confinement fusion （ICF） and physical tests of the quasi-spherical load in the future.
