| 摘 要： | 沙层应变观测是一个全新的前兆观测，目前对它的研究还非常少，用淮安台、怀来台及合肥台的数据进行了对比，通过日变化特征、长期变化特征、年变化特征、干扰因素及噪声分析几个方面，从而对该观测手段进行更进一步的分析。

| Abstract: | Sand layer strain observation is a brand-new precursor observation,which is little researched.The data collected from Huaian,Huailai and Hefei station are compared and analyzed.The characteristics are analyzed in terms of the daily change,long-tern change,yearly change,disturbance factors and noise,which lead to a bettle understanding about the observation method. |
