axial diffusion coefficient轴向扩散系数
1.33 r/s,the results showed that the axial diffusion coefficient increased with the increase of liquid velocity and gas velocity,and first increased then decreased with the increase of the stirring speed while the gas hold-up increased with the increse of stirring speed,liquid velocity and gas velocity increased.33 r/s条件下,轴向扩散系数随着液速和气速的增加而增大,随着搅拌桨转速的增加先减小后增大;平均气含率随着液速、气速及搅拌桨转速的增加而增大。

轴向扩散规律轴向扩散是指城市圈经济沿着一定方向（通常是以交通主干带为主）向外扩散的过程。轴向扩散可能是由于交通主干线的因素；也可能是受地理条件的制约。但无论是什么因素影响，它都体现出城市圈经济以中心城市为核心向外放射状的扩散规律。
