在联合反演中，GPS资料主要作用在于确定地壳运动的现时性，地震矩的作用主要是确定运动的趋势性。

In the joint inversion study , the update status of crust movement mainly ascertained by GPS data , but the trend of the movement mainly ascertained by seismic moment tensor data .

计算得到地震矩为1.5×10（22）N·cm，说明唐山地震前后一年内的垂直形变是同震变化。

The seismic moment calculated is 1 . 5 × 10 ( 22 ) N · cm . It indicates that the vertical deformation within one year before and after earthquake is coseismic variations .

从这一观点出发，根据尾波随掠过时间的衰减特性，结合地震矩对数和地方震里克特地震级的线性关系，导出利用任一掠过时间的震尾来计算的尾波震级Mc公式。

On this view , in consideration of linear relation between the seismic moment and the local Richter magnitude , a formula of the coda magnitude M_c is derived by using seismic coda of any lapse time , measured from the earthquake origin time .

从频谱曲线上得到拐角频率fo的不确定数是1.31，地震矩Mo的不确定数是1.43。采用平均的方法，可将应力降Δσ的不确定数由2.4降到1.6。

The certain numeral of the corner frequency ( fo ) is 1.31 and the uncertain one of the seismic moment ( Mo ) 1.43 respectively from the spectral lines The uncertain factor of stress drop can be reduced from 2.4 to 1.6 by using mean method .

地震矩与拐角频率呈现出良好的双对数关系，且该地区的地震应力降与震源半径之间的关系在震源半径小于300m时与圆盘静态破裂模式理论关系较吻合。

The relation between the moment and corner frequency takes on double logarithmic law . When the source radius is smaller than 300 m , the relation between the stress drop and source radius tallies with the theoretical law of the disk static rupture model .

整个破裂持续了约142s.破裂过程可粗略地分为3个阶段：第一阶段，从第0s开始至第52s结束，持续了52s，释放的地震矩约为总地震矩的24.4%；

The entire rupture lasted for 142 s , and the source process could be roughly separated into three stages : The first stage started at the 0 s and ended at the 52 s , lasting for 52 s and releasing approximately 24.4 % of the total moment ;
