通过分析影响恒温水浴温度均匀度的相关因素,对其均匀度测量不确定度进行了评定,并给出了相应的评定结果及计算方法,得到了合成不确定度和扩展不确定度。 By analyzing the related factors that affect the temperature uniformity of the water bath, the measurement uncertainty of the uniformity measurement was evaluated. The corresponding evaluation results and calculation methods were given, and the synthetic uncertainty and the extended uncertainty were obtained.
