| 摘 要： | 本文从网络的回路分析和网络灵敏度分析的增量法出发，将矩阵的张量运算应用于电路的灵敏度分析中，导出了计算电路支路电流和支路电压灵敏度的一般公式，该方法用于电路灵敏度计算，只需要进行一次电路分析和一些矩阵变换与运算，即可得到电路中支路电流和支路电压对电路参数的灵敏度矩阵。该方法是文献1]的对偶形式，与文献1]所提出的方法互补形成较为完备线性网络灵敏度分析方法。

| Abstract: | A systematic method of sensitivity analysis for linear circuits is discussed on the basis of loop-analysis approach. Applying the matrix operation, a general formula is derived for calculating branch current and branch voltage of the circuit concerned. Using this method to sensitivity calculation, the matrix of sensitivity of branch current and branch voltage against circuit parameters can be obtained by only once circuit analysis. It is the dual form of the method proposed in document 1]. Two methods, proposed by this article and document 1] respectively, consist of a complete set of methods for the sensitivity analysis of linear networks. |
