点火靶用芯轴微球小批量测量

基于VMR显微镜系统，提出了一种小批量测量聚-甲基苯乙烯(PAMS)芯轴直径和球形度的方法，初选满足技术指标的微球。小批量测量1 mm标准球，测量结果95%出现在（998.21.2）m之间。测量值与标准值之间的偏差为标准值的0.06%，扩展不确定度偏差为测量值的0.24%，说明该批量测量结果准确度和稳定性较好。将此方法应用于PAMS芯轴初选，与手动测量结果相比，批量测量结果的偏差具有单向性，且最大偏差约10 m，满足初选测量要求。

Batch characterization of ignition target mandrels

With the increase of capsule requirement, a method for batch characterization of the diameter and sphericity of poly (-methyl styrene) (PAMS) mandrels is developed based on the VMR microscope system. The sources of uncertainty in characterizing the diameter are analyzed and every uncertainty component is evaluated. The 95% results of a 1 mm standard ball are in the range of (998.2-1.2) m to (998.2+1.2) m, showing excellent precision and stability of batch characterization. The characterization method is also used in measuring the PAMS mandrels. Compared with the results characterized on MM-400 microscope by hand, the deviation of the diameters of PAMS shells characterized by batch shows unidirectionality, and the maximum value is about 10 m, within the requirement of 15 m.
