摘　　要：本文用国际电工委员会(IEC)建议的方法对市场上几种常见类型家用微波炉的输出功率、均匀性及安全性进行了更仔细的测定.由我们的工作得出结论:测量微波炉功率时,用2000g水作为负载较为合适,且负载面积应占腔体底面积的16%以上,此时测出的功率更准确和接近标称功率,而测定微波炉漏能时则应使用较小负载.转盘转动时负载的受热均匀性较转盘静止时提高约1倍.The properties of several domestic microwave ovens have been measured in more detail according to the method suggested by IEC. The results show that the output power of an oven can be measured more accurately by using a water load of 2000g. But when measuring the leakages of an oven, it is better to use a load of 500g. The heating uniformity of a load in an oven is improved up to 70-80% when the load is moved on a turntable.
