摘要：

用AFM轮廓仪测量了ICF靶丸3个相互正交方向上的表面高度数据。分析了测量数据的误差来源，给出了消除表面异常扰动和偏心距两类误差的方法和原始数据预处理步骤，采用最小二乘法评定了靶丸球度。给出了靶丸表面形貌一维功率谱估计计算方法和表面粗糙度的计算方法。

Abstract:

The ICF capsule surface data on three orthogonal directions have been measured with a surface profile-meter. Surface debris and eccentricity were found to be the main error source of measurement; the methods to eliminate the tow errors and steps to pre-process these data were put forward, furthermore, the least square method was adopted to evaluate the capsule’s roundness. Finally, an average one-dimensional spectra calculation method was given, and the relation between mode-spectra curve and capsule surface topography were presented.

Key words: ICF capsule, Surface topography, Surface profile-meter, Power spectra estimation
