| 中文摘要 |
| 本文从频域最小二乘拟合出发，提出了高阶线性定常时间连续数学模型降阶为低阶线性定常时间离散模型的直接方法。本方法算法简单，便于编制计算机辅助设计程序，使降阶设计高度程序化；概念明确，在宽广的频带内具有较高的拟合精度，易为工程实际所应用。 |
| 英文摘要 |
| This paper presents a method for directly reducing high-order linear continuous time-invariant model to low-order linear discrete time-invariant model. The method is computationally simple and easy to be programmed on computer. The main features of the method are clarity in concept and relatively high precision in frequency domain and so can be applied to engineering problems. |
