你见过的最小的微波炉有多小?

To date, the device, which stands just 7.4 inches tall by 6.2in wide and 5.9in deep, is only a prototype. However, experts at the Microwave Association insist the sophisticated miniaturized technology does exist to turn the eye-catching gadget into a reality.

　　该设备立起来高7.4英寸，宽6.2英寸，厚5.9英寸。到目前为止，它还只是样本，并未投入生产。不过，微波协会的专家们认为，利用已有的尖端微型化技术，这个引人注目的新发明可变成现实。

　　Apart from its size, the key breakthrough is the use of a combination of mobile phone radio frequencies to create the heat to cook.

　　除了体积小，这款微波炉关键的突破在于使用一组移动电话无线电频率来加热（食物）。
