锅炉等温曲面轴测图的计算机绘图研究

THE ISOMETRIC PROJECTIOR DISCUSSION OF CONSTANT TEMPERATURE SURFACE IN BOILER

锅炉等温曲面轴测图的计算机绘图问题主要包括温度数据到三维坐标的转换、等温节点的筛选、重新排序、样条插值方法的选择及绘图程序的编写等。现对这些问题进行了比较全面地研讨，并在研讨的基础上用ＱＢＡＳＩＣ语言编程绘制出等温曲面的轴测图。

The computer plotting isometric projection problem of constant temperature surface in boiler includes conversion from temperature data to three dimension data,screening and rearrangement of equal temperature node selection of spline interpolution and compiling plotting program. All those have been discussed relatively overall in this paper,and isometric projection of constant temperture surface is plotted in QBASIC language program.
