摘　　要：能力验证是实验室质量保证的重要手段,能力验证样品指定值的确定直接影响到能力验证结果评判的准确性,采用参加者公议值作为指定值是一种常见的指定值确定方法。该方法的准确程度受限于参加者的数量,在参加者数量较少时,由该方法确定的指定值不确定度较大,如参加者数量过少,甚至不能进行能力验证结果的判定。Proficiency testing is an important means of laboratory quality assurance.The determination of the specified value of proficiency testing samples could affects the accuracy of the evaluation of proficiency testing results directly.It is a common method to determine the specified value by using the agreed value of participants.The accuracy of this method is limited by the number of participants.When the number of participants is small,the uncertainty of the specified value determined by this method is large.If the number of participants is too small,it can not even determine the result of proficiency testing.
