摘　　要：偏振－同步荧光法能有效地抑制同步扫描过程中散射光总水平的影响，外加磁场效应能有效地抑制散射光的波动。二者结合起来用于同时测定屈、蒽、苝，　检测限改善近６７倍。该法相对标准偏差小于２．７％。The total level of scattered light intensity can be reduced by polarization technique,while the undulation of scattered light can be suppressed by magnetic field.When these two techniques were combined with the resonant synchrononus spectrofluorimetry,the detection limits of chrysene,anthracene and perylene can be improved 13.2,24. 3 and 67 times respectively.The relative standard deviation is less than 2.7%
