摘要: 介绍了用于侧照明实验研究瑞利-泰勒流体力学不稳定性(Rayleigh-Taylor instability)实验的聚苯乙烯和铝平面调制微靶的制备工艺。通过图形转移，靶型切割和装配工艺的控制，结合靶参数测量，获得了厚度在几十μm、表面具有波长50 μm和55 μm、振幅从几到几十μm、微靶宽度约为200 μm、剖面正弦调制图形清晰的两种靶型。

Abstract: This paper introduces fabrication of polystyrene and aluminum surface perturbation targets used for flank illumination Rayleigh-Taylor instability experiment. By figure transfer, incising targets, controlling constructional technique and measuring targets' parameters, we obtained surface perturbation targets with sinusoidal surface perturbation figures with thickness of several tens micrometer, the wavelength about 50 micrometer and amplitude from several to several tens micrometer. The width of two kinds of eargets is about 200 micrometer and the profile is clear.-
