In the establishment process of three dimensional visualization model, we proposed the contour line drill hole - multi-layer face mold method.This method which improves Delaunay triangulation, is suitable for the random polygon triangulation and is easy for computer to realize. It makes three dimensional stratum visualization model of picking area realized under the limited condition.

在三维地层可视化模型的建立过程中，提出了基于等高线的钻孔—多层面模型方法，这是一种对现有的Delaunay三角剖分方法进行了改进，该方法适用于任意多边形的三角剖分，且易于计算机实现，使采区的三维地层可视化模型在有限条件下也能够实现。

In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory.

本文建立了求解挤出口模内幂律流体流动速度场的通用三维罚有限元模型；对于非线性粘弹性的Phan Thien-Tanner流体，为了降低模拟计算对计算机硬件的要求，并使模拟计算更加稳定，采用了一种去耦算法，包括罚有限元方法、拟体力方法和动量方程的椭圆类方程转化方法，并建立了求解速度场和粘弹性应力场的总体有限元方程；对于PTT流体的挤出胀大问题，提出了挤出胀大熔体口模内外分离模拟法，这样可以显著降低数值模拟对计算机硬件的要求。

The culture can be described in the four-dimensional or three-dimensional degree.
