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。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.
