其结果显示距声源10公里外，只使用单一声速剖面之音传模拟会产生较大的误差；10公里之内差值小于1分贝。
The results showed that using single sound speed profile at source produced errors at simulation range large that 10 km.
基于标准差和变异系数两个指标，采用聚类分析，可将土壤剖面水分垂直变化划分为四个层次：速变层、活跃层、次活跃层和相对稳定层。
Based on the standard deviation and variation coefficient, soil water change in the profile could be divided into four layers by cluster analysis.
