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。

Fortunately, the modern geodetic measurements such as the Global Positioning System 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。

First, we introduce the linearly distributed stress tensors as the source and by means of two-dimensional finite-difference scheme to obtain the response of this source, then the point source response is generated by correcting both the wave forms and geometrical spreadings for the linear respons.
但在理论地震学,工程地震学和勘探地震学中横向不均匀介质中的波传播问题非常重要,此时使用有限差分法和有限元法等离散数值方法比较有效。鉴于目前计算工具的限制,三维模型的有限差分计算虽然在理论上是可行的,但很少能用于实际。
