A possibility of automatic detection of the surfacestreamline position by analysing the oil visualisation images is discussed.
讨论了通过油流显示图像的分析，自动探测表面流线方位的可能性。

In addition, due to the streamlinesurface, the shape resistance is reduced, thus lowering the flowing pressure loss and the fluid transportation energy consumption.
另外，重要的是由于其流线型表面，使得形状阻力减小，从而降低了流动压力损失，减少流体输送能耗。

Preferably, the streamlinesurface of the shell is gradually shrunk from the head to the tail, and the rear openings are symmetrically distributed around the Central Line of the shell.
