| 摘 要： | 本文利用浙江地震台网记录的近震资料,用多元回归分析法建立了单台和多台统一的持续时间震级公式,并对影响回归方程精度的因素作了分析讨论.文章认为,为了保证 M_D 的精度,必须考虑仪器放大倍数和震中距的影响.误差分析和检验结果表明,本文求得的 M_D 公式可以显著改进震级测量精度和系统偏差,适合浙江台站使用.

| Abstract: | In this paper, the formula for duration magnitude with data at a slngle
station or several stations combined is established by using the methods of multiple
linear regression analysis with the near shock information by the seismic network
of Zhejiang province;and the factors which influenece the precision of the
regression equation are analysed and discussed.Meanwhile, it is indicated in the
paper that it is necessary to consider the magnification of the instruement and
the influence of the epicentral distance to guarantee the magnitude precision.The
results of error analysis and practical examination show that improvement of the
magnitude precision and minimization of systematic deviation can be achieved
through the M_D-formula, this is put forward in the paper and suitable to the
seismic network of Zhejiang province. |
