For the PEFR data, there is no obvious relation between the difference and the mean. Under these circumstances we can summarise the lack of agreement by calculating the bias,estimated by the mean difference d and the standard deviation of the differences ( s ). If
there is a consistent bias we can adjust for it by subtracting d from the new method. For the PEFR data the mean difference (large meter minus small meter) is - 2.1 l/min and s is 38.8l/min. We would expect most of the differences to lie between d - 2s and d + 2s (fig 2).If the differences are Normally distributed (Gaussian), 95% of differences will lie between these limits (or, more precisely, between d -1.96s and d +1.96s ).
拜托，不要机译啊！！！

此答复请楼主放心采用
For the PEFR data, there is no obvious relation between the difference and the mean.对于PEFR（呼气流速变化率）数据来说，在差别和平均值之间没有明显的关系。Under these circumstances we can summarise the lack of agreement by calculating the bias,estimated by the mean difference d and the standard deviation of the differences ( s ). 在这些情况下，我们可以通过计算偏差总结出符合性（协议）的缺失，此偏差可用差别的平均差别d和标准偏差加以估算。If there is a consistent bias we can adjust for it by subtracting d from the new method. 如果存在一个始终如一的偏差，我们就可以调整它，那就是从新的方法中减去d。For the PEFR data the mean difference (large meter minus small meter) is - 2.1 l/min and s is 38.8l/min.对于PEFR（呼气流速变化率）数据来说，平均差别（大表计减小表计）为38.8 l/min。 We would expect most of the differences to lie between d - 2s and d + 2s (fig 2).我们将预计大多数差别处于d - 2s 和d + 2s (图 2)之间.If the differences are Normally distributed (Gaussian), 95% of differences will lie between these limits (or, more precisely, between d -1.96s and d +1.96s ). 如果这些差别是正态（高斯）分布的，那么95％的差别将处于这些极限之间（或者更确切地说，处于d -1.96s 和 d +1.96s之间）
