假如现在这个比率是最低的、并且放在防喷器上方的关键性管道适应了高帽之前、仍然保持低比率，那时候泄漏的油约相当于现在已经漏掉量的一半。

If the rate is at the low end of the range and was lower still before a key pipe on top of the blowout preventer was cut to accommodate the top hat, about half as much oil has been spilled so far.

而且在反应温度和空速越低、剂油比越大、反应时间越长的条件下，催化裂化反应受干气比率的影响越明显。

The impact of dry gas on FCC reaction becomes increasingly pronounced with lower reactor temperature and lower hourly space velocity, greater catalyst to oil ratio and longer reaction time.
