The results revealed the changing laws of the velocity of waste plastics particles and gas, the volume fraction of the waste plastics along the pipe range in the course of pneumatic conveying.
模拟结果揭示了废塑料气力输送过程中废塑料颗粒速度、气体速度和颗粒体积分率沿管长的变化规律以及管径的改变对废塑料颗粒体积分率的分布和固气比的影响。
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.
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。
"Given that uncertainty, the amount of material spewing from the pipe could range from 56, 000 barrels to 84, 000 barrels a day." UK.
不大肯定地说，每天从管道中泄露出来的原油总数范围大概从56000桶到84000桶。
