【摘要】 本文导出含有稳定参数的stiff微分方程问题的一种数值方法。这里，我们主要推导含有稳定参数s 的二阶和三阶Adams型方法。当s＝0时，这种方法只不过是古典的Adams法。我们可以选择参量S，以改进绝对稳定性，即扩大绝对稳定性区域。对于更高阶的方法，可采用类似的方法加以推导。更多还原

【Abstract】 In this paper, a numerical method with stable parameter for the solution of Stiff Equations is derived. Here, we chiefly derive the Adams second order and three order method with stable parameter S. When S = O. this numerical method is simply a classical Adams method. We can choose parameter S to improve ab- solute stability, i.e. to extend the region of absolute stability. For a much hig- her order method, the derivation can be made in a similar way.更多还原
