根据“十五”项目需要，编制“十五”地震前兆数据连续率统计软件，用于黑龙江省“十五”地震前兆项目库，效果好、速度快，给出每套仪器每个测项统计时段数据的完整率表，圆满完成《试运行工作报告》的编写，效率提高。
According to needs of "the tenth five-year plan”, we design software for data integrity rate statistics of earthquake precursor database. The software which applied in the precursor project database works well and efficiently. Data integrity rate tables of each observation item of each set of instrument are given for compiling the work report of trial operation efficiently. A systematic prescription of the implementation for data integrity rate statistics of observation items of the provincial precursor database is given in this paper.
