Normally distributed data assumes that about 68% of the values in the sample are within 1 standarddeviationof the mean.
正态分布数据认为，样本中约68%的数值分布在距离平均值为1的标准偏差之内。

Measurement ofsample: single sample automatic measuring, measuring the number of times 2, 3, 5, 10, 50 set, measured at the end gives the average value and standarddeviation.
样品测量：单样品自动测量，测量次数2、3、5、10、50次任意设定，测量结束给出平均值和标准偏差。
