摘要
为减小实验误差,提高检验精确度,采用合并样本标准偏差计算检验结果的不确定度。实验表明,采用合并样本标准偏差计算检验结果的不确定度方便且适用。
The indeterminacy of test result was estimated by combining standard deviation of specimen in order to decrease the experimental error and increase the test precision. The experimental results indicated that the method to calculate the indeterminacy of test resuit by combining standard deviation of specimen is convenient and applicable.
