摘　　要：收集整理了山东省数字化形变台自观测以来的固体潮分钟值资料 ,论述了气压、雷电、洞室进人、仪器故障及附加载荷等干扰因素对数字化形变高频记录的影响及其机理 ,为利用数字化资料及时识别干扰。All of the minute data of digital solid tide observed at deformation stations of Shandong province have been collected and studied in this paper. The factors and their mechanisms of different disturbances such as pressure, thunder and lightning,man's entering into the cave and instrument trouble affecting on the high frequency part of digitalized deformation observations are discussed. In this paper some practical examples for distinguishing the disturbing patterns and catching short impending term anomalies are also presented.
