有一类特殊的非线性系统，它遵从广义的叠加原理。在代数上，这类系统用输入和输出的矢量空间之间的线性变换来表征，因而称为同态系统。-A special class of nonlinear systems, which comply with the broad principle of superposition. In algebra, such systems use linear transformation vector space between the inputs and outputs to characterize, so called homomorphic systems.
