The effects of the height of auxiliary electrodes,the different pressures and the flux of argon on relative intensity of laser microemission spectra of aluminum alloy standard samples have been studied with the use of CCD in argon atmosphere at reduced pressure, using CuI 324.7 nm,ZnI 334.5 nm and MgI 383.8 nm lines. The spectral lines with high signal noise ratio can be obtained in argon atmosphere at reduced pressure. The experimental conditions have different effects on relative intensity of spectral lines for different element. And the maximum of relative intensity of spectral lines are obtained at the same condition for different element, while matrix effect can be neglected.
