摘要
推导了某些流线或光滑圆截面缆的流体动力特性，给出的算例表示了流线型和圆缆之间的主要性能差别，算例表明使用流线型缆是有一些益处的，除了可以抑制震颤效应外，还可以在同样拖体重量下得到更大拖体深度或者同样深度下采用更高的拖速，但也会带来一些不利之处，如使上端张力增加。一般说来，从拖体向上三分之一长度采用流线型时便可获得全部采用流线型时的一半拖曳深度；当一半缆长采用流线型化则可获得这一深度的７５ ％ 。
The hydrodynamic properties of some faired and bare cables are given. Examples given in the paper illustrate the main performance differences between bare and faired cables, and the benefits to be gained from the use of a fairing, e.g. greater tow speeds at the same depth or greater depth at the same fish weight in addition to the suppression of strumming. However, these gains have to be weighted against some of the disadvantages. The upper end teusion will be increased. On average one achieves about 50% of the fully-faired depth gain when one third of the scope is faired from the fish upwards and 75% when half the cable is faired.
