求翻译:The size of wire rope used on mooring winch barrels is governed by the weight of wire managdable by the crew :this is currently accepted as 140 mm circumference maximum.The basic problems associated with the use of wire ropes is that they are dificult to handle do not float and when used in multi-layers,due to inadequate spooling,the top,tensioned layer cuts down into the underlying layers causing damage .To counteract this latter problem a divided barrel can be used such that the wire may be stored on one portion and a single layer of wire transferred to the strength portion when tensioned.Low density,high breaking strength synthetic ropes polypropylene , nylon ,terylene etc. Offer certain advantages over wire,its main disadvantage being a crew to fuse if serubbed against itself or the barrel.是什么意思? 待解决
