| Abstract: | In this work, the effect of the molten splash ball was solved via the deep electrodes, drilling, and overlapping spectra of the emission spectrum when the spectrum of the sample taken from the molten splash ball, to test the quality of the impact brought by two-electrode spectrographic ensure the qualification of the samples tested at 95% the above. This way can improve the test sample pass rate, and low detection limit, high sensitivity, good accuracy, high accuracy and other technical indicators. |
