The coefficient of repeatability was calculated according to the method of the British Standards Institution

British Standards Institution. Precision of Test Methods, I: Guide for the Determination and Reproducibility for a Standard Test Method (BS 5497, part 1). London, UK: British Standards Institution; 1979.

请问各位大侠谁有上面的文献啊？主要是想知道Repeatability coefficient 重复性系数是如何算出来的！它与重复性r是同一个意思吗？
