| 摘 要： | 根据等值面的概念，把等值线图的算法理论扩展到三维空间，提出了由空间离散分布的量值寻找其等值面的方法，并应用曲面拟合技术，实现了等值面图的计算机绘制与显示。研究结果为解决在三维结构分析中用三维图形来描述具有空间分布规律的物理量时所面临的难题，提供了新的途径。

| Abstract: | According to the concept of Isopleth Surface, the algorithm theory of isopleth drawing is expanded to 3 D space. Thereby, a method to find an isopleth surface from some dispersed points value in 3 D space is presented. Also, the curved surface fitting technology and computer display principle are used to achieve the drawings and displays of the isopleth surface. Thus, a new way is presented to solve the difficult problem when using 3 D drawings to describe a physical quantity with space distribution. |
