| 摘 要： | 流线对流场的描述是场描述的一种基本形式，在生成流线算法中质点追踪算法是简单而快速的。但是，质点追踪算法在流线行进过程中会产生歧义点。为了解决地下水流场三维流线可视化中质点追踪算法产生歧义点的问题，本文从流线的定义出发，以流线方向为K·J取最大值的方向为原则，提出了降维行进算法，并对一个理论模型定义的流场进行了流线可视化研究，实现了流场的三维流线模拟与可视化表述，其结果与理论研究相吻合。

| Abstract: | Streamline is an elementary form for describing the flow field, and particle tracking is one of the simple and fast algorithms. However ambiguous point becomes the problem while tracking. The paper sets out from the definition of streamline and proposes an algorithm called Reducing Dimensionality Tracing, considering that the orientation of the streamline is the same of the orientation which makes max. Then the algorithm is implemented to the flow field defined by a theoretical model, getting the flow field streamline which is corresponding to result of theoretical research. |
