| Abstract: | It has quite practical worth in engineering to study the temperature fieldand the heat conduction process of the spherical body. accordingly, we resea-rched and found the differential equation of heat conduction in the sphericalcoordinate system. In this article methods of the differential volume elementand the coordinate transformation are used to build the differential equationof heat conduction in the spherical coordinate system. |
