通过对煤气加压站煤气泄漏源点的分析和确认，并对其泄漏源点采取充氮密封和局部强制通风等手段，以达到降低煤气区域爆炸等级的目的，并对煤气加压站防爆等级进行了探讨性划分。

The means of sealing by nitrogen aerating and local forced ventilation are used for the leakage source points so as to reduce the explosion class in the gas zones.

昨夜，受损大楼内辐射等级“极其高”，该大楼被早先的爆炸破坏，这表明辐射现在可能已经进入周围环境中。

Last night radiation levels were "extremely high" in the stricken building, which was breached by an earlier explosion, meaning that radiation could now escape into the atmosphere.

因为爆炸后辐射等级没有上升，我们能很确信燃料库是毫无损失的。

Because radiation levels didn't rise after the explosion, we can be pretty certain that the bunker is still intact.
