The heat-transfer system consists of both the heat-releasing solid body (spheroid, cylinder of height H→∞, or plate with area S→∞) and the infinite solid medium. In this system, heat energy transfers only by conduction, and the amount Q of free heat energy is constant with respect to time, although its distribution continuously changes.展开更多
