摘　　要：为了解决了目前光谱夹具的单一性问题,研究并开发了多功能光谱夹具,并将其用于火花放电原子发射光谱分析中。多功能光谱夹具是融合了传统的立式和卧式夹具的原理改进而成,通过合理的拆卸设计,完成棒、线、管、片材和球状样品的分析测试。根据卧式光谱夹具的原理,可用于外径或宽度在1.0~10mm之间棒、线、管、片材样品分析;另外该夹具根据立式光谱夹具的原理,将圆球形样品借助不锈钢钢管、弹簧及螺栓完成了向棒材样品转换,通过定位板和V型板的定位,可用于外径在2.5~10mm之间钢球样品的测定。In order to solve the unity problem of existing spectrometer fixtures,a kind of multifunctional spectrometer fixture was developed and studied for the spark discharge atomic emission spectrometric analysis.The multifunctional was modified according to the principle of conventional vertical and horizontal fixtures.Through reasonable design for disassembly,the analysis and determination of bar-shaped,lineshaped,tube-shaped,sheet-shaped and spherical samples could be realized.Based on the principle of horizontal spectral fixture,it could be applied for the analysis of bar-shaped,line-shaped,tube-shaped or sheet-shaped samples with outer diameter or width in range of 1.0-10 mm.Moreover,according to the principle of vertical spectral fixture,the developed multifunctional fixture could convert the spherical samples to bar samples with the aid of stainless steel tube,spring and bolt.Through the positioning of batter board and V-type board,it could be used for the determination of spherical steel samples with outer diameter of 2.5-10 mm.
