A seismograph produces wavy lines that reflect the size of seismic waves passing beneath it 地震仪能产生反映在其下面通过的地震波大小的波状线。
Some experiences in the management maintenance and observational application of digital seismic instruments 数字地震仪器的管理维护及在观测应用中的几点体会
The seismographic network will be redeveloped to further boost the collection of information on seismic activity 将重新开发地震仪网络工作，进一步加强地震活动信息的收集体制。
To determine the strength and location of earthquakes , scientists use a recording instrument known as a seismograph 为确定地震的强度和位置，科学家使用一个被称为地震仪的记录仪器。
According to ctbto , ims array comprises 9 vertical short peroid ( sp ) seismometers and a broad - band seismometer Ctbto规定ims台阵应配置9台短周期垂直向地震仪加一台宽频带地震仪。
The hong kong observatory plans to acquire a broadband seismometer next year to replace the existing long - period seismometer 02秒至100秒的震动都有一定的敏感度，弥补了现时长周期及短周期地震仪的不足。
Scientists locate earthquakes by measuring the time it takes body waves to arrive at seismographs in a minimum of three locations 科学家通过测定体波到达地震仪所需要的时间，以3个距离中最小的一个来确定地震的位置。
