| 摘 要： | 建立了稳态热传导问题的有限差分方程,编写了相应的温度场差分计算程序,借此可求得不同恒温边界条件下带内热源的矩形区域内的温度分布,然后采用计算机图形学原理编写了图形显示程序,并将所得离散的温度分布数据转化为相应的图形.最后,基于所得计算图形讨论了相应区域内的热传导特性.

| Abstract: | The finite difference equation of steady heat conduction is established,and the related computer program is compiled to solve the heat conduction problem in a rectangular field with different known boundary temperatures and internal heat sources.The graphic display program is formu-lated in terms of computer graphic theory,which transfers the discrete temperature data to corresponding graphics.The heat conduction characteristics of several domains are ascertained by ana-lyzing the distribution of their equi... |
