The direction of the principal compressive strain obtained in the paper is well consistent with the principal compressive stress axes derived by the geological and seismological methods.

用本文方法得到的主压应变方向与地质学方法和测震学方法得到的主压应力轴方向具有很好的一致性。

More than 40 years practices on earthquake prediction indicates that seismography has provided the most information for earthquake prediction practices.

40年地震预报实践表明，测震学方法提供了当前地震预报工作最大部分的地震预测信息。

Based on the analysis on seismicity and variations of some seismometry indices in Wulateqianqi region,Inner Mongolia from 1998 to July,2000, seismicity trend of the region in future is studied.

通过对 1 998～ 2 0 0 0年 7月内蒙古乌拉特前旗地区的地震活动特征及一些测震学指标变化特征的分析，研究了该地区未来地震的活动趋势。

According to the calculation results of some seismometry index of the aftershock sequences,the whole aftershock sequence could be divided into two sub-sequences,or the main event-aftershock sequence distributed in the Wenchuan area at the south-west part of the fault and the seismic swarm sequence with several large events of ...

根据对汶川地震余震序列的部分测震学指标计算，结果表明，汶川地震序列可能是由以绵竹为界，其西南段的汶川主-余震序列和绵竹北东段的北川-青川6级震群地震序列组成，汶川地震可能具有龙门山活动构造的继承性运动特点。

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.

在系统分析并筛选出华北地区地震频度、地震活动标度、mf值、调制比、b值、D值、η值、地震活动强度熵和地震活动时间熵等映震较好的9项测震学参数基础上，应用综合异常指数方法，分别计算了它们各自的地震异常指数时序值，进而合成得到华北地区测震学综合异常指数时序曲线，通过研究其地震短期异常特征，给出了华北地区M≥5.8地震短期综合预测的判据指标，经R值评分检验表明，该指标具有较好的地震预测效能。

By synthetically analyzing the variation characteristics of pre-earthquake anomaly before five moderate-strong earthquakes in East China since 1990,discussing the pre-earthquake anomalous shape of b value and so on we obtained the comprehensive criteria for medium and short-term earthquake anomaly before moderately strong earthquake in East China:high YH value anomaly—low b value anomaly—low C and YH value anomaly—low Ds and Dt and Σ value anomaly and high b value anomaly—earthquake.

通过对华东地区1990年以来5次中强以上地震震前异常变化的综合分析，探讨了b值，Ds，Dt，C值， YH值，Σ值震前异常形态，并归纳出华东地区中强地震发生前测震学中短期异常的综合判据：YH值高值异常(主要出现在震前3年前后)—b值低值异常(平均出现在震前2年前后)—C、YH值低值异常(大体出现在震前1～2年前后)—Ds，Dt值低值异常、Σ值低值异常、b值高值异常(主要出现在震前1年内或稍长)—发震的模式。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
