摘要：

生物医学温度验证系统被广泛应用在我国的医疗卫生行业,为了评估其性能,需要计量机构对温度验证系统进行校准,但目前我国还没有制订其校准的相关标准和规范。现根据温度验证系统的性能特点,在误差理论的基础上对该系统的准确度进行分析,提出一种元件分项校准和系统整体校准相结合的校准方法。实验证明该方法可以准确、全面地对温度验证系统的性能进行评定。

Abstract: At present, biomedical temperature verification system is broadly used in the field of medical and hygienic industry, so it is very important to evaluate its performance, orderly, the calibration of the temperature verification system is needed for metrology organizations. But there is no standard or regulation for that in our country. On the basis of error theory and the function characteristics of temperature verification system, the authors have analyzed the accuracy of this system, and have suggested a calibration method which connecting the calibration of parts to the calibration of the whole system. The experimental results prove that this method can evaluate the performance of the biomedical temperature verification system accurately and comprehensively.
