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.
提出了一种k-均值聚类算法和SOM自组织神经网络算法相结合的异常检测模型，使得系统可以更好的分类正常数据流和异常数据流，以此来防范未知的攻击。
Secondly, the anomaly detection model based on K-means algorithm and SOM network is constructed. It can classify the normal and abnormal network data stream so better to detect the unknown attack.
数值模拟同时还发现流动性指标属于一种统计平均值而并非恒定不变的常数值，这将有助于对流动性评价指标的重新思考和定位。
Bi-channel fluidity test modulus simulation suggests that different channel formed different length in a practical experiments, it also proved fluidity indexes should be an average value.
