摘　　要：基于棒状燃料元件导热微分方程的一般形式,推导了反应堆动态工况下棒状燃料元件温度分布随时间变化的解析表达式。应用该表达式,进行了模拟计算。结果与实际工况的误差在可接受范围内,验证了该解析式的正确性。Based on the current form of differential equation of heat transfer, the analytic expression of temperature change with time of cylindrical fuel element was deduced in dynamic status. Analog computation was carried out by this expression. Then the correctness of this solution was validated.
