恒等变换

研究了D-共调和变换，证得D-共调和变换事实上就是恒等变换。

We study the property of D-conharmonic transformation and obtain that the D-conharmonic trans-formation is actually the identity transformation .

首先将电路结构抽象为特定的数学模型，再对这一数学模型进行恒等变换，最后将数学模型转化成电路。

First the circuit structure is abstracted as a specific mathematical model . Then the mathematical model is set under identity transformation . Finally , the mathematical model is turned into circuits .

针对B.Friedland的工作，本文提出了有色噪声补偿模型，在恒等变换下显式地消去了有色噪声项，利用正交投影定理仅对感兴趣的状态分量导出了无偏、最小方差估计。

A colored-noise compensation model is proposed with respect to B , Friedland 's paper . The colored-noise item is apparently eliminated by the identity transformation , and the unbiased minimum variance estimation towards a part of the state components is obtained by means of the orthogonal projection theorem .
