从烟囱里冒出的烟消散中我们可以明显地看到涡流扩散。
Eddy diffusion is apparent in the dissipation of smoke from a smokestack.
这些引起了严重的污染问题，因为通过分子扩散的传质比涡流扩散的要慢。
This cause serious pollution problems because mass is transferred less rapidly by molecular diffusion than by eddy diffusion.
同时，最近几天一个特殊涡流已经加强并向北扩散。
Meanwhile, a particular eddy has intensified and expanded north in recent days.
卫星图像表明这个涡流已经卷着原油向东南方向扩散了100英里(大约160千米)，也就是说原油现已在这片汹涌的水域中流动。
The images reveal that the eddy has snagged oil and pulled it southeastward 100 miles (about 160 kilometers), which means the crude is now circulating inside the turbulent waters.
数值结果表明，蜗壳内的速度场以及压力场分布相对比较均匀，在隔舌和扩散段内存在一定的回流和涡流，但并不影响泵的良好性能和高效率。
The results show the distributions of the velocity field and pressure field, especially for the flow in laryngeal and diffuse part. There are refluence on...
