利用微波加热方法测定了不同水样中的高锰酸盐指数，讨论了微波功率、时间、酸度等条件对分析结果的影响，并与标准方法相对照，用ｔ － 检验法及 Ｆ－ 检验法检验，均没有明显差异．
The permanganate index in different water samples was determined by microwave heating method. The influence of microwave power, time, acidity and other conditions on the analysis results was discussed. Compared with the standard method, t - test and F - test Test, no significant difference.
