【摘要】 简单介绍了液体自动颗粒计数器的两种非球形颗粒标定方法: 旧的ISO4402 (1977) 非球形颗粒 (ACFTD)标定法和新的ISO11171 (1999) 非球形颗粒 (ISOMTD) 标定法。分别采用旧粉尘的标定方法 (ACFTD) 和新粉尘的标定方法 (ISOMTD) 对颗粒计数器进行尺寸标定后, 然后对同一瓶样液进行分析。结果表明: 不同的标定方法的标定结果的差别不大, 对样液分析的结果在允许的误差范围内。更多还原

【Abstract】 Two non-spherical particle calibration methods of automatic particle counter,the ISO 4402 (1977) ACFTD and the ISO 11171 (1999) ISO MTD,were introduced.A automatic particle counter which was calibrated respectively by using two different methods,the old ACFTD and the new ISO MTD,was used to analyze the same oil sample.The tests show that the results of the two sizing calibrations are almost consistent with each other.更多还原
