把这一标准差和两次的平均值相比较，我们就能发现他们很相像，（因为我们知道重力加速度是个常数）。
Comparing the ratio of standard deviation to the average for these two distributions shows that they are similar.
单位砂浆体积下集料的表面积的变化对邻近集料表面最近间距的平均值有影响，但二者之间的比值并非常数。
The surface area of aggregate per unit volume of mortar does have influence on the mean value of the nearest surface spacing, but the ratio between them is not constant.
随后再将时间常数的平均值与预先存储的数据对照表做比较，以确定传感器的温度。
Finally, comparing the value of the time constant with the data comparison sheet, the temperature of the sensor can be confirmed.
