利用蒙特卡洛法对微波功率测量不确定度进行评定。介绍了蒙特卡洛法评定测量不确定度的过程，给出了基于MATLAB 实现蒙特卡洛法评定的步骤。分别使用单批次蒙特卡洛法和自适应蒙特卡洛法评定给定频率下微波功率测量不确定度，并与 GUM 法结果进行比较和验证。结果表明除标准不确定度值蒙特卡洛法和 GUM 法相差5%外，其他结果几乎一致，蒙特卡洛法验证了 GUM 法，完全适合微波功率测量不确定度评定。蒙特卡洛法能处理线性模型，在各不确定度分量相差较大情况下优势明显，同时简单、方便，易于推广。
利用矇特卡洛法對微波功率測量不確定度進行評定。介紹瞭矇特卡洛法評定測量不確定度的過程，給齣瞭基于MATLAB 實現矇特卡洛法評定的步驟。分彆使用單批次矇特卡洛法和自適應矇特卡洛法評定給定頻率下微波功率測量不確定度，併與 GUM 法結果進行比較和驗證。結果錶明除標準不確定度值矇特卡洛法和 GUM 法相差5%外，其他結果幾乎一緻，矇特卡洛法驗證瞭 GUM 法，完全適閤微波功率測量不確定度評定。矇特卡洛法能處理線性模型，在各不確定度分量相差較大情況下優勢明顯，同時簡單、方便，易于推廣。

The measurement uncertainty of microwave power was evaluated by Monte Carlo method (MCM).The evalu-ation process of measurement uncertainty was introduced with MCM,and procedure of MCM with MATLAB was given. Both single batch MCM and adaptive MCM method were used to evaluate measurement uncertainty of microwave power at a given frequency.The results from two MCM were compared with GUM method.It showed that the results were al-most identical,addition to 5% deviation in standard uncertainty between MCM and GUM.The MCM validated GUM and was fully fit for evaluation measurement uncertainty of microwave power.The MCM can deal with linear model per-fectly,and its advantage is obvious in the case of similar components of uncertainty,and it is simple,convenient,and easy to spread at same time.
