摘　　要：为了验证实验室校准方法制定的合理性,对测量结果的不确定度进行评定,发现测量方法中不确定度的主要贡献因素,从而通过改进方法抑制或减小该因素的影响,使方法趋于合理。实践证明,不确定度评定是验证校准方法制定合理性的重要手段之一。In order to inspect and verify the rationality of laboratory method establishment, uncertainty evaluation of measurement results should be done to find out the major contributors of measurement uncertainty, so that it can suppress or diminish the influences of those factors through improving method and make the method more reasonable. The practice results proved that uncertainty evaluation was one of the important ways to inspect and verify the rationality of laboratory method establishments.
