Lett., 495, 202-212, doi: 10.1016/j.epsl.2018.05.020. 我们处理震后形变数据如下：首先矫正和汶川地震无关的其他影响，例如季节变化，年际变化，板块效应等；再次，通过指数函数和对数函数拟合震后时间序列曲线；最后，通过拟合曲线计算任意时间段震后形变量。震后10年累积形变高达近21厘米。水平方向精度不低于1.7厘米，垂直方向不低于4厘米。","doi":"","projection":"","language":"zh","share_type":"protected","east":106.0,"west":100.0,"south":30.0,"north":34.0,"scale":null,"crs":null,"filesize":0.01,"share_policy":"c","ts_created":"2021-06-23T14:48:52.162583+08:00","doi_type":"国际公开共享数据","ts_updated":"2021-07-05T11:17:50.717630+08:00","time_description":"","datas_group":0,"time_description_en":"","data_format":null,"project":[11],"specials":["b6500306-f60b-4aa1-b0b6-0324d94866df"],"cite":null,"review_status":5,"review_invite":[{"user_name":"何思明","username":"何思明","email":"hsm@imde.ac.cn","is_cancel_expert":false}],"review_editor":{"id":66424,"last_login":"2021-08-31T17:09:37.293773+08:00","username":"YanHou","email":"ljz2hy@163.com","is_active":false,"is_staff":false,"user_name":"侯燕"},"data_sources":null,"temporal_resolution":"Yearly","spatial_resolution":"<= 1 m","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[21],"subtopics":{"metadata":"129e37ce-e054-40be-a4ec-e5aa4f052ba0","three_pole":null,"third_pole":null},"username":"宋培平","review_time":null,"protected_duration":24,"protected_describe":null,"is_important":false,"hit_count":867}
