By PDE tool box, you neednt program and can enter the GUI directly to solve practical engineering problem. By analyzing the example of slab with the point heat sources heat transfer, the result show s that it is raopid and simple by using PDE tool box to solve common problem. T he engineering impor tance about the point heat source heat transfer model is also mentioned. Key words: temperature field; PDE tool box; nonsteady state heat conduction; point heat source 1 2 DE , MATLAB ( PDE) , , , ( ) , , : PDE , - ( c u) + u = f ( 1) MATLAB PDE PDE , - ( c( u) u ) + ( u) u = f ( u) ( 2) - ( c u ) + u = du ( 3) : 2005- 02- 25 PDE : ( 1980 ) , , , . d ( u t) - ( c u ) + u = f ( 4) 32 27 3 2005 5 PDE
