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。

Seismographic surveys carried out across the atlantic ocean have shown that there are many deviations and unexplained contours to be found right at the bottom of the ocean 大西洋安放地震仪调查显示发现有许多偏离和不明原因的等高线正好就在大海的底部。

But these aren t the only types of graphs ; some forms of data , especially time - based data such as share prices or seismographic data are best plotted on line graphs 但这并不是惟一的图形，某些形式的数据，特别是基于时间的数据（如股票价格或者地震数据） ，最好用线图来表示。

Fortunately , the modern geodetic measurements such as the global positioning system ( gps ) technique can overcome the shortage of the geological and seismographic methods in the time dimension ; and yet , the coverage of the geodetic survey stations is not sufficient . as a result , it is necessary to employ numerical simulation to investigate the continuous deformation of the crust 而以全球定位系统( gps )等技术为主的大地测量方法弥补了地质和地震学方法在时间维上的不足，但大地测量方法存在测点覆盖不足及测点地理分布不均匀的缺点，因此，要得到连续的地壳形变场有必要借助数值模拟方法。

The characteristics of the movement and deformation of the crust were traditionally determined with the geological and seismographic methods . however , the result obtained with the geological and seismographic methods is virtually an average one on the time scale of millions and / or hundreds of years , and the current movement and deformation of the crust cannot be described well 传统上，一般用地质和地震学方法来确定地壳的运动和变形特征，但二者确定的地壳形变结果分别是百千万年和百年左右的平均结果，难以描述现今地壳运动和变形的特征。
