Commanders look to cruise in cold-water eddies or just below boundaries between seawater layers , each of which can help refract sound away from the ocean surface .
潜艇指挥官通常希望航行在冷水漩涡或在海水层交界处的下方,这些位置有助于将声音折射出海面。
To test their ability to identify eddies , the researchers again used the mit towing tank .
为了测试发现涡流的能力,研究者再次使用了mit的牵索水箱。
Based on the pressure signals , a flow model estimated the position and strength of the eddies .
在压力信号的基础上,一个流体方程测算了涡流的位置和力度。
The cylinders spin in opposite directions , creating suction that immediately prevents eddies from forming .
气缸向相反的方向旋转,所产生的吸力立刻阻止了涡流的形成。
The olivine , megeath and his colleagues believe , might have been blasted out by jets of solar gas rather than lazily carried out by cosmic eddies .
