The graph ic display program is formu- lated in terms of computer graphic theory, wh ich transfers the discrete temperature data to corre- spond ing graph ics. The heat conduction characteristics of several domains are ascertained by ana- lyzing the d istribution of their equ ivalen-t temperature lines.
