【摘要】 根据安徽省地震局规定使用的表面震源《走时表》 ,按其精度要求 ,把震中距分成三个距离段进行程序设计。在数据处理上 ,对 4 6°以内的数据 ,为保证精度 (0误差 ) ,采用数据检索方式 ;而对 4 6°～ 13 5°之间的数据 ,在保证精度的前提下 ,先进行线性拟合 ,解出一系列关于Δ的函数方程 ,再进行程序编制 ,在实际使用中发挥了较好的作用。更多还原

【Abstract】 Based on the travell time table of surface focus required by the Seismological Bureau of Anhui Province, the data process pragram of dividing epicentre distance as three range according to accuracy requirement is designed. In order to guarantee accuracy(zero error) the data retrieve manner is used for the data of the epicentre distance less than 4 6°, and first a linear fit is given for one of 4 6～13 5°,the function equations of a series Δ are resolved, then the program is given.更多还原
