The test results show that by controlling the T-junction and riser tube's resistance coefficients, the unbalanced riserflow distribution has been achieved.
试验结果表明，控制三通及各上升管的局部阻力系数，可以实现上升管流量不均匀分配。

Originally the preventer was linked to the Deepwater Horizon by a mile long vertical pipe called a riser, through which oil would flow.
最初，防喷器与深水地平线平台由一根一英里长的垂直管相连，这根管子叫做立管，石油既由此通过。
