摘要
编制了用3种方法独立计算a本征值的计算程序,并分析了深次临界情况下a本征值计算遇到困难的原因。计算结果表明:改进的直接法计算范围宽、精度高,是解决深次临界情况下a本征值计算困难的有效途径。
Three codes were developed to compute the alpha eigenvalue using three dif-
ferent methods. It was also analyzed why alpha eigenvalue computation would fail in
deep subcritical systems. The computed results indicate that the modified direct compu-
tation compared with other methods has the advantage of wide calculational range and
high precision. It is an effective method to solve the difficulty of alpha eigenvalue com-
putation in deep subcritical systems.
