开展了基于蒙特卡洛法（MCM ）的噪声参数测量不确定度评定工作，以等效噪声参数方程作为不确定度评定的测量模型，利用从测量系统获得的物理量求解函数方程，得到反映等效噪声参数分布情况的数据，并从等效噪声参数导出噪声参数及其概率分布，最后得到噪声参数测量的不确定度。该方法有效地结合了数学随机仿真、物理测量边界判据，实现了噪声参数测量结果的不确定度评定，该方法符合国际标准，可应用的测量系统种类多，普适性高。最后通过实验数据验证，证明了评定方法的有效性，不确定度评定数据的真实性和可靠性。

This article researches on the uncertainty evaluation of the Noise‐Parameter Measurement with Monte Carlo method .Measurement model depends on the equivalent Noise‐Parameter equation .With this model ,function equation re‐sults from the measurement system parameters are calculated in order to obtain data which describe the equivalent Noise‐Pa‐rameter distribution ,then deduct Noise‐Parameter & its distribution from equivalent Noise‐Parameters ,and lastly get the measurement uncertainty .This method realizes uncertainty evaluation of the Noise‐Parameter Measurement ,using combina‐tion of numerical random emulation and parameters boundary criterion ,which is consistent with international standard and widely used in a great many systems .Finally ,this article proves efficiency of the evaluation method and the reality and credi‐bility of the uncertainty evaluation data .
