利用P波到时确定近震震源参数的循环优化迭代法的误差分析

ERROR ANALYSIS FOR THE PERIODIC OPTIMUM ITERATION METHOD FOR DETERMINAGION OF THE HYPOCENTRE PARAMETERS OF NEAR EARTHQUAKES BY USING THE P-WAVE TRAVEL TIMES

摘要:

利用P波到时确定近震震源参数,文献[1]给出了一种迭代解法-循环优化迭代法。用这种方法对五个参数φ,λ,T₀,h,υ全面进行优化时,需要分别算出所得近似解的误差,只当它们全部满足精度要求时,才能做为我们所需要的近似解,否则,还要对不满足精度要求的量继续进行优化。如何计算所得近似解的误差,该文并没有真正解决这个问题。

Abstract:

In this paper we have established calculation formulas to estimate errors,σ_φ,σ_λ,σ_T0,σ_h and σ_v,of the approximate solution,starting from error equation using the idea of "error concentration"。These fo-rmulas can be used as the important constituent of the periodic optim-um iteration method。
