地震记录的

Channels and polarity judging and correcting for the digital strong motion accelerograph in field work

这次地震使震中及其附近地区的5台数字强震仪触发，记录了5组3分量数字加速度记录。

From local records of earthquakes and aftershocks, we knew that on the day following a magnitude7.3 event , the chance of another large shock striking within100 kilometers is nearly67 percent—20,000 times the likelihood on any other day.

从当地的地震和馀震记录来看，在100公里範围内，我们知道在规模7.3的地震后，发生其他大地震的机率为67%是平常的两万倍。

Some colleger uses university of on potato net one paragraph of Sichuan the video that the mobile phone films, be as long as 1 minute of 50 seconds, recorded an earthquake the dormitory is mixed at that time the circumstance inside campus, the rate that exceeds 100 times with every second by refresh.

土豆网上一段四川大学某学院学生用手机拍摄的视频，长达1分50秒，记录了地震当时宿舍和校园内的情况，以每秒超过100次的速度被刷新。14点46分国家地震局通过新华社发布了汶川7.8级地震的消息，1分钟后新浪网便通过互联网、手机短信和手机Wap平台做了转发。

In the process of seismic data,seismic numerical modeling can be used to test some inverse methods.

在地震数据处理中，地震数值模拟计算出来的记录数据可以检验各种反演方法的正确性。

Some methods, in which synthesized theoretical seismogram of high frequency is taken as record signal and 20%random noise is superimposed on the seismogram, are used to analyze the theoretical seismogram. The digital experiment shows that in the correlating frequency range, Green's function method can measure precisely interstation phase velocity, but the results obtained by correlation and narrow band-pass filtering correlation methods are more dispersed.

以合成的高频理论地震图作为记录信号，并在理论地震图上叠加了20％的随机噪声，利用这些方法分析理论信号，数字实验表明：在相干频率范围内，格林函数方法能够精确测量台间相速度，而互相关法和窄带通滤波互相关法所得结果较为离散。

The main factors effecting on exploration precision of surface wave are analyzed in the light of calculation of phase velocity of surface wave; the merits and demetits of common computing methods for phase velocity between stations and their applied range are discussed and calculation of interstation Green's function for correcting phase is put forward to get the precise phase difference between two stations.

分析了影响面波勘探精度的主要因素，针对计算面波相速度的精度问题，讨论了常用测量台间面波相速度方法的优缺点及其适用范围，并提出通过测量台间格林函数进行相位校正，以得到两台之间的精确相位。以合成的高频理论地震图作为记录信号，并在理论地震图上叠加了 2 0 %的随机噪声，利用这些方法分析理论信号，数字实验表明：在相干频率范围内，格林函数方法能够精确测量台间相速度，而互相关法和窄带通滤波互相关法所得结果较为离散。

This is advantageous to the analysis of the effect of nonstationary characteristics on the structural responses.

最后，进行结构地震时程分析时，输入地震波的确定是基础，仅依靠现有的地震加速度记录往往不能满足要求。

Experts have said that there are no recorded cases of a natural earthquake causing a mine collapse in Utah, and that seismographic data is more consis-tent "with the collapse being the cause of the 'earthquake' rather than the other way around".

拒专家们介绍，到目前为止，尤他州还没有关于地震导致煤矿坍塌的记录，而地震学数据更支持坍塌是引起地震的原因，而不是相反。

The museum will feature a quake-relief training center, a quake-escape training center, a wall memorializing those who died in the quake and a monument dedicated to those who assisted local quake relief, according to the plan.

根据该计划，博物馆将附有地震救灾训练中心和地震逃生训练中心，一面缅怀在地震中丧生的人们的墙和一座记录协助抗震救灾的人们的纪念碑。

The results show that the hal＆daily and half-monthly tidal wave perio- dicity changed abnormally about one month before the earthquake, with periodicity disappearing and amplitude reducing, but they recovered after it with clearer state than that at normal time.

分析了在2004年12月26日印尼8.7级地震前河北昌黎台记录到的自然电位及电场异常，结果显示昌黎台自电位、电场正常时段观测到的半日、半月潮汐波周期变化在震前1个多月发生畸变，周期消失，变化幅度相应减小，震后快速恢复，且潮汐波记录比震前正常时段更加清晰。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
