Note that the amount of heat required to melt enough ice to raise sea level one meter is about 12 watt - years ( averaged over the planet ) , energy that could be accumulated in 12 years if the planet is out of balance by one watt per square meter 要让海平面上升一公尺所需的融冰热能，全球平均要12瓦特，只要每平方公尺有一瓦特的不平衡量、累积12年，便可达成。
Such tags , which are still the most widely used , typically need to be less than a meter away from a reader and offer poor discrimination ( a reader cannot quickly interpret a multitude of individual tags grouped closely together ) 这类标签仍是今日的主流，但它们与读取机之间的距离通常必须小于一公尺，而且可辨识度相当差，读取机无法快速区分出堆在一起的大量标签。
