摘　　要：针对当前分析预报工作的实际需要 ,介绍了“九五”攻关中连续形变 (倾斜、应变及重力固体潮 )观测的一些实用化研究进展。重点介绍了经分析研究后筛选出来的前兆参量、异常信息提取方法及有关判别准则 。Aimed at the practical need of earthquake prediction and analysis work, we introduced the development of practical research on continuous deformation (tilt, strain and gravity solid tide) observation in the key task of “the 9th five year plan\' in this paper, especially the precursory parameters of continuous deformation, extracting methods of anomalous information and its discriminant standard. In addition, we gave a check and a statistical analysis of the practical efficiency of every precursory parameter and analysis method based on long time and large range of observed data.
