摘要: 本文利用Gear方法计算了"异形环流器极向场三级电源"中一类Stiff方程组。文中详细叙述了Gear方法的用法及自动调整步长和自动变阶问题,并与单步方法进行了比较,结果表明Gear方法比单步方法省机时。

Abstract: A set of stiff ordinary differential equations in power supply for poloidal field of noncircular takamak is solved using Gear method. Gear method, self-adju stable step length and Self-Variable power are described in detail. Compared to single step method, Gear method spends less time.
