Large temperature and concentration differences taking place in CVD process lead to natural convection and concentration diffusion which interact with forced convection and complex reactor geometries.

在CVD过程中，存在着大的温度差和浓度差，将引发自然对流和浓度扩散，它们又与气体的强迫流动以及反应器的几何尺寸和形状相互影响。

The action means the Yongbyon reactor complex, where the plutonium for North Korea's presumed small arsenal of nuclear weapons was produced, will be without international monitoring for the first time in nearly two years.

Looking back more than a year after the event, it is clear that the Fukushima reactor complex, though nowhere close to state-of-the-art, was adequately designed to contain radiation.

Mr. Edano said another reactor in the same complex, one that was not operating at the time of the quake, was on fire Tuesday morning.

Tuesday's explosion at the No. 2 reactor in the Fukushima complex, 150 miles north of Tokyo, for the first time raised the possibility that the key containment structure of the unit, which protects the reactor vessel and keeps dangerous radioactive materials from leaking out, had been damaged.
