| 中文摘要 |
| 本文探讨了用于模型简化的带偏连方式法，提出了一个带偏连方式展开和反演的具体算法，并根据可调参数法的思路，对带偏连方式法做了进一步改进，改进后的方法逼近精度较好，应用灵活，在频率特性上，既能实现整个频段上有侧重的逼近，又能实在在某些特定频率处较精确的拟合。最后通过例题进行了计算比较。 |
| 英文摘要 |
| In this paper, the biased continued fraction approximation method for system reduction is discussed. Improvement of this method is made. An algorithm for expansion and inversion of the biased continued fraction is proposed. A biased continued fraction method with adjustable parameters which has good approximate solution and flexibility is provided. The reduced model not only approximates with bias the frequency response of the original model, but also provides precise matching at some particular frequencies. An example is given. |
