ONE reason for Japan’s reliance on nuclear power—with all its attendant difficulties of building reactors safely in an earthquake zone—is its lack of indigenous energy sources.

日本依赖核能的一个重要原因在于它缺乏固有的能源资源，伴随而来产生了必须要在地震带上建造安全的反应堆，但这是非常困难的。

And this looks a lot like the average valence electron energy where the lowest values of electronegativity are in the metallic zone and the highest values of electronegativity are on the nonmetallic zone.

这看起来像是平均电子能,最低的电负性在,金属区最高的电负性在,非电子区。
