讨论了带低阶项的梁的平衡方程的广义解法，分析了解的稳定性、收敛性和存在唯一性。

In this article, we discussed generalized methods for solving the beam eguilibriurr equation with low order terms, analysed stability, convergence and uniqueness of the solution.

然而，在实际应用中，随着子带数目增加而增加的收敛速率却最终受限于不理想的滤波器组和有限字长效应。

However, in practice, the convergence improvement gained by increasing the number of subbands is ultimately limited by nonideal filter Banks and finite-word-length effects.

带钢热连轧精轧机组穿带后的头部厚度精度- - -头部命中率将直接影响绝对AGC的工作，其重要手段是靠提高设定模型精度、模型自学习的收敛速度。

It is necessary to hit accurately the head of the strip for applying absolute AGC in hot rolling mill, important means are to improve accuracy of set-up model and convergence of self-learning model.
