摘要: 摘要：针对激光惯性约束聚变物理实验打靶所需的氘氚燃料塑料微球靶进行微球强度和渗氘性能初步研究，测量了塑料微球球壳在20（室温）、40、60 ℃下的压缩强度，并实验测得了塑料微球在20、60 ℃下的氘气渗透率。

Abstract: The penetrating performance of D₂ in plastic microspheres was studied. The compressive strength and the permeability coefficients of plastic microspheres were obtained by filling D₂ wtih different pressures in hollow plastic microspheres at 20, 40 and 60 ℃, respectively. The compressive strength of plastic microspheres obviously drops when the temperature rises within a small range. The permeability coefficients of plastic microspheres increase in an exponential curve when the temperature rises.
