| 摘 要： | 研究了激光惯性约束聚变靶用PS-PVA-CH三层塑料空心微球采用热扩散法高温高压充氘气技术。实验研究表明，对于直径300 μm、PS壁厚5～7 μm、PVA壁厚3～5 μm、CH层厚4～6 μm的塑料微球，50℃充气的平衡时间为20～40 h，70℃的平衡时间为7～12 h，90℃的平衡时间为2～4 h。在室温25℃时，微球的气体渗透系数为（3.0～4.2）×10-19 mol·m-1·s-1·Pa-1，对应的保气半寿命为28～37 h。对于参数接近的微球，如果充气时间相同，充气外压与微球内压基本呈正比。当外压达到6.0 MPa时微球开始出现破损。

| Abstract: | The purpose of this paper was to describe hollow plastic microspheres filling with D2 which served as inertial confinement fusion（ICF）targetsThe microspheres were 300 μm in diameter and were composed of three layers：PS with 5—7 μm wall thickness，PVA with 3—5 μm and CH with 4—6 μmThe primary experiments showed that the equilibrium time was 20—40 h at 50℃，while 7—12 h at 70℃ and 2—4 h at 90℃The equilibrium time increased by about 10 times from 90℃ to 50℃The deuterium permeability of hollow plastic microspheres was （3.0—4.2）×10-19 mol·m-1·s-1·Pa-1 at room temperature（25℃）.This corresponded to the half time for D2 retention to be about 28—37 h. |
