【摘要】 正交配置法是一种加权余量法,利用它可以方便地将偏微分方程组的初边值问题化为常微分方程组的初值问题。本文详细地介绍正交配置方法,并利用该方法研究了一个汽——水加热器分布参数模型的动态特性。更多还原

【Abstract】 Being a kind of MWR, the orthogonal colloacation method canbe conveniently used to reduce the initial-boundary value problems of the partial differential equations to initial value problems of ordinary differential equations. In this paper, the orthogonal collocation method is introduced in detail and by using it the dynamic characteristics of a steam-water heater are investigated.更多还原
