the results show that reducing the slit width can improve yield of powder injection.
结果表明:减小狭缝的宽度有利于提高喷粉的有效利用率;
according to the structure of instrument, the influence of the slit width on spectral line is discussed, the relative measurement error of instrument is also analyzed.
investigations have been made to analyze tungsten in steel (analysis lines chosen: w 4008.76 and w 2397.11) with various are current, slit width and electrode spacing.
