When all elemental equations can be described by a set of constant parameter values, as in the familiar RLC circuit, the system is said to be stationary or time-invariant or constant coefficient.

当所有基础方程都能用一组定常参数值来描述，正如熟知的RLC电路的情况，就称该系统是稳态的，或时不变的，或常系数的。

Through comparison between theory proof and simulation, we find the approximation method is feasible in linear time invariant (LTI) system of concentration and distribution parameter.

通过理论推导与仿真结果的对比可知，数据关联抖动估算方法对线性时不变的集总参数，分布参数系统均是可行的。
