温度时间等效
By using the equivalence between the solution of boundary problem for differential equation and functional extreme value, cut-and-try methods are used for the finite element methods ( FEM), solution of unstable temperature-field inside grain-layer in the process of grain drying.
利用求解微分方程的边值问题和泛函求极值问题的等价性,进行了谷物干燥过程中谷物层内部非稳态温度场的有限元解尝试。
The reactivity equivalence of 8 groups ( 49 clusters) was calibrated. The integral worths were measured separately by rod changing method, taking the temperature adjuster rod bank as the known differential worth of rod bank.
以温度调节棒组作为已知微分价值的棒组,对8组共计49束的反应性当量,用换棒法作了积分价值测量。
