摘　　要：　概述了当前研究Rayleigh Taylor不稳定性增长实验所用的靶型情况。从实验用靶来看,调制靶的设计正从平面向立体发展,出现了球形和柱形等新靶形,制备手段包括精密机械微加工、激光束、电子束和离子束加工、半导体工艺和微米纳米技术加工等。根据对国外新靶型的研究,结合国内工艺条件和实验需求,对国内可能采用的靶型进行了研究探索。Designs of targets used in the current Rayleigh-Taylor instability experiments are analyzed and summarized in this paper. The preparation of the perturbation target is developing from two-dimensional to three-dimensional. New designs such as spheric and cylindrical target appeared. Preparation techniques include micromachining, laser, electron and ion beam etching, semiconductor technology, and nano-technology. Laser two-beam interference and electric plating technique for planar target fabrication is studied. According to the novel foreign designs as well as domestic conditions and need, possible designs for recent use such as rapid prototyping and EDM technique for cylindrical target and laser machining technique for spheric target fabrication are proposed.
