It is demonstrate that sr realized by turning system parameters can be explained as sr via adding noise after a transformation . it is found that sr via turning noise could be made equivalent to turning system parameters and adjusting signal amplitude accordingly . but the psr method can appear under the more worse environment than sr via adding noise does 本文对于参数调节随机共振与传统的噪声调节随机共振联系与区别进行了研究，经过尺度变换后，二者是可以相互解释的，参数调节随机共振就是寻找传统的噪声调谐共振峰值所对应系统的一种理论和方法，它具有适应范围广和调节方便的优点。
