( 4 ) on the efficient method for the dynamical core of the new generation multi - scale forecasting model i ) we present a new multi - level sparse approximate inverse preconditnioner for the complicated 3 - d helmholtz equations in the new generation weather forecasting model. as a result, the new sparse approximate inverse preconditioned gcr and gmres algorithms are given and successfully applied in the dynamical core. numerical tests show that the new algorithms perform very efficiently, and can greatly improve the efficiency of numerical model
對此，本文提出了一種基於逐層門限技術的近似逆矩陣稀疏模式預選方法，並構造了相應的稀疏近似逆預條件子，結合gcr演算法和g州[ r衛s演算法，首次將逐層門限稀疏近似逆預條件子應用於新一代多尺度預報模式動力內核的實際計算，數值實驗表明這里給出的方法可以大大提高數值模式的計算效率。 -
The results show that in our research ptt ( pressure, time and temperature ) region the corrosion resistant effect of treated uranium depends on the treated time. the passivation film thickness maybe have an effect on the corrosion resistance. the electrochemical corrosion resistance of treated uranium in the solution ( 50ug / gcr ) has been studied by electrochemical measurement
