哪个品牌的钢丝绳最好

跳绳减肥怎么选择跳绳

跳绳减肥怎么选择跳绳？跳绳不仅可以用来燃脂，还可以用来热身，也是增加肌肉耐力最好的运动之一。虽然说跳绳这个东西比较简单，但是如何选择适合自己的跳绳，还是需要做功课的。那么跳绳减肥怎么选择跳绳呢？

一、最值得买的跳绳推荐

跳绳这个东西大家肯定都比较了解，所以我也不说那么多废话了，直接上硬菜。

为了方便大家挑选，直接给出四款最值得购买的跳绳，盲撸这四款绝对不会出错。

1、普为特

这是一款负重的双模式跳绳，有负重功能的就非常好。

像我这种老司机来说，我通常会选择这种有负重的，太轻的跳绳满足不了我的训练需求。

这款细节做得特别好，手柄防滑耐磨，握感也很舒适。

而且他是PVC加粗的钢丝绳子，在使用的时候绳子不会绳子不会飘，不易绕。

这款价格最低，但质量非常不错，性价比非常高，预算有限的朋友们可以考虑这一款。

2、京东京造

这一款也是双模式跳绳，而且是一款智能计数的跳绳，还可以切换有绳和无绳模式。

这款跳绳配备了 一块高清智能显示屏，不仅可以计数。

还可以查看卡路里消耗、倒计时、电量显示自己模式切换，一键搞定，简直太香了！

他的续航功能也很好，充一次能用三十天。

我最喜欢的还是他的颜值，太有质感了。

要求颜值又要求功能齐全的，买它准没错。

3、LATIT

LATIT这个品牌John之前也介绍过，大品牌的品控没得说。

这是一款双模式智能负重跳绳，轴承是钢制的，特别的顺畅，不会有卡顿的情况。

手柄是硅胶的，握感非常的舒适。

我在超市买过一次塑料的，一出汗容易打滑，非常不舒服，所以在选择跳绳上手柄材质非常重要。

这款的智能系统非常好，我在测评的时候，时间、圈数从没出过错。

从外观到内在全面在线，绝对值得冲！

4、LOOP

这一款也是有绳无绳双模式的智能跳绳，据说国家队在训练的时候用的就是它。

绳子的质量非常好，毕竟价格摆在这，非常耐用抗造，稳定不飘。

而且这款跳绳有自己的app，通过蓝牙连接，实时的记录运动信息，还可以根据运动计划安排科学的学习视频。

它的手柄是弯的，用起来感觉更省力，非常适合人体工程学。

充电两小时就可以超长待机45天，太适合我这种记性不好的人了。

这一款我用过之后立刻安利给了我的朋友，本来还觉得价格略高，但用过才知道它贵有贵的道理。

大家如果预算充足，不用考虑别的，无脑冲这款就好了！

二、跳绳的好处有哪些

1、减肥：

跳绳是特别高效的有氧运动， 运动时间短，但热量的消耗非常高，能够很好地使脂肪燃烧，结实肌肉。

最好的例子是我当时的学员，不靠别的只靠跳绳，半年瘦了26斤，巨牛！

2、提高肌肉耐力：

跳绳能让你的肌肉变得更紧实，耐力变得更强。虽然它不和撸铁一样能对肌肉进行针对训练，但是它可以让身材的整体线条变得更好看。

3、增强体质：

跳绳能促进血液循环，增强肺活量，改善心脏供血功能。

还可以促进新陈代谢，对正在发育的青少年来说，也会有辅助增高的作用，还是要多运动啊朋友们！

4、增强协调性：

跳绳可以增强身体的协调性和灵敏度，不仅可以锻炼的身体更灵活，对于手眼协调也是一种很好的训练。

如何挑选跳绳

市面上跳绳的种类真的太多了，在选择上说简单也简单，但是选择到适合自己的并不容易。

下面John会从几个方面详细给大家分析一下，接着往下看。

1、单模式/双模式跳绳

单模式和双模式说白了就是有绳跳绳和无绳跳绳。

单模式

单模式跳绳指的就是有绳跳绳，大家最先接触的基本都是有绳跳绳；

优点是价格比较便宜，缺点是不耐用，或者材质不好绳子容易卷起来；

不过有绳跳绳相比无声跳绳的热量消耗更大，一些专业的比赛训练都会使用有绳。

双模式

双模式值得是支持有绳和无绳来回切换的跳绳，无绳跳绳的更适合在室内，不会产生噪音；

不过无绳跳绳的热量消耗不大，所以现在的主流基本都是负重的无绳跳绳。

双模式比起单模式来说价格会稍微高一些，不过要多一个选择，我个人还是比较推荐双模式的跳绳。

John总结：选择双模式最好，双模式既可以无绳又可以有绳；

居家室内用无绳，室外或者专业训练用有绳，来回切换特别方便。

2、绳子材质

① 塑料/橡胶跳绳

优点：价格低 结实耐用 不易打结 适合新手

缺点：重量轻 容易发飘 手柄握感不好

② 竹节跳绳

优点：适合花式跳 颜色鲜艳

缺点：不适合快速跳绳，易坏易断

③ PVC钢丝跳绳

优点：不易打结，适合更专业的人，甩动更快更好的锻炼肌肉耐力

缺点：打到身上有点疼，如果在室内的话噪音大

④ 尼龙跳绳

优点：价格便宜，轻便耐磨，柔韧性好

缺点：重量太轻，用着回发飘，甩动时手感不好掌控

总结：John建议新手直接选择pvc钢丝材质的跳绳就可以了，完全可以满足各种训练需求。

3、跳绳的重量

跳绳一般可以分为重绳和轻绳；

一般普通的跳绳80～120克，80克以下就太轻了，不建议购买；

400克以上，就属于重绳了，而且现在无绳跳绳基本都有负重，对减脂非常有效果。

总结：新手可以选择100～200克的重量，随着肌肉耐力的`增加，可以根据需求加重。

4、绳子的长度

建议购买可调节长度的跳绳，调节适合长度的方法是：用双脚踩住绳子，两手握住手柄，把绳子拉直，手柄可以到腋下，就是适合自己的长度。

随着自身水平的提高，也可以适当调短长度。

大家可以参考以上几点，从这几个方面找到自己的需求，然后再根据自己预算去选购。

首先在训练前，以下的注意事项一定要注意：

1、要做好充分的热身，准备防止拉伤肌肉扭伤关节。

2、跳绳时应该选择质地软、重量轻、底子薄的鞋子。

3、绳子的重量和长度要适中。

4、选择软硬适中的场地联系，尽量避免在硬质的水泥地上跳绳，以免损伤膝盖。

5、体重基数较大的朋友们要循序渐进练习。

训练方法：

1、固定时间

可以规定好时间比如说10分钟或者15分钟。新手们可以根据自己的能力来定时间。

在这个时间内连续的跳不要停止，如果太累了，或者坚持不了的话，可以通过调整速度来进行调节。

通过慢慢地练习后期可以增加难度，比如说速度上的增加，或者快速慢速交替，以及时间上的增加。

2、间歇跳

这个方法我在教学的时候通常会用到新手身上。我会固定，好时间，比如说2分钟到3分钟，或者也可以固定次数，150个或者300个。

快速地跳绳，完成一组后可以休息30秒到1分钟， 然后再继续跳，反复的进行训练。对于新手，我也会要求他们做四组以上。

大家可以根据自身能力来增加或者减少次数，John建议最少做四组。

3、动作变换

可以通过不同的动作来锻炼不同位置的肌肉，以及身体的协调性。

动作上有很多可以变换，比如左右跳、两腿高抬腿交叉跳、前后跳、单脚跳、还可以双飞跳（跳起来挥绳两次），根据能力，每个动作跳30秒或1分钟。

这样变换不同的动作，可以提高大家的兴趣，免得枯燥不好坚持，也避免单一动作导致很快进入平台期。

不管是什么样的训练计划和训练动作，都要结合自身的能力，循序渐进地进行训练。不要盲目的追求多、快、重，一切训练以不会造成训练伤害为主。

总结

在买任何器材前，一定要多对比，多了解，找准自己需求再购买。

当然兄弟们有我，我会帮大家筛选出最合适的产品。

挑选适合的产品有我，但是能不能坚持运动还得靠自己呀，加油吧铁铁们！

Purse seiners catch primarily pink salmon and herring by encircling them with a long net and drawing (pursing) the bottom closed to capture the fish. The net is first stacked on the stern of the boat and then played into the water while the boat travels in a large circle around the fish. The far end of the net is attached to a power skiff, which holds the net while the seiner completes the circle. The top of the net stays on the surface of the water because of its float line—thousands of colorful floats—and the bottom of the net falls vertically because of its weighted lead line. As a result, the net hangs like a curtain around the school of fish. The vessel crew then purses its bottom with a purse line. The lines and the net are pulled up with a hydraulic power block (winch). Once most of the net has been retrieved, with the remainder of it lying in a bag alongside the vessel, the fish are dipped from the bag and into the vessel’s hold. For large catches of herring, a buying vessel or tender comes alongside the fishing vessel and lowers the end of a fish pump into the bagged purse seine. The herring are then brought aboard the tender and into its hold without ever going aboard the seiner. Sometimes referred to as limit seiners, purse seiners are sleek, cabin forward vessels that are limited by Alaska law to 58 feet in order to more precisely manage their fishing effort. They are recognized by their long, clean decks, the boom with its power block, the net stacked on the back, and the power skiff that is often seen riding piggyback aboard the vessel’s stern while it is traveling. When fishing, of course, the circle of floats on the surface of the water, and the power skiff assisting with the operation, are sure giveaways. Seine-caught salmon are delivered in-the-round (whole) to buying stations and canneries where they end up as canned and frozen products. Herring are delivered to processing plants where they are either stripped of their roe (eggs), or packaged as bait for other commercial fisheriese.g., the longline fisheries and the crab fisheries. Salted herring roe, called kazunoko, is shipped to Japan where it is a high-priced delicacy.

【围网渔船】

围网渔船主要捕捞粉鲑和鲱鱼，方法是用一张长网把鱼群包围，然后收拢网底将鱼捕获。

先将渔网堆放在船尾，之后渔船围绕鱼群行驶，路线呈大圆圈状，一边行驶一边往水里撒网。网的最末端系在小动力艇上，渔船围着鱼群转圈时由小艇固定住网。网的顶端有浮绳，由无数彩色浮球组成，能使网顶浮在水面。网的底部有加重过的铅绳，使网底垂直降下。最后，网围绕鱼群像窗帘一样挂起来。之后船员用收拢线将网的底部收拢。收拢线和渔网由一台液压动力滑车(绞机)拉起。网的大部分收回后，剩余部分会收到船边的袋子里，然后船员把鱼从袋子里倒到船舱里。大量捕捞鲱鱼时，会有一艘购买船或运输船靠在捕捞船旁边，并将一个鱼泵末端降低伸到装围网的袋子里。鲱鱼直接被带到运输船的船舱内，不用先收回到围网船上。

有一种“限制性围网船”，船型圆滑，船舱朝前，长度被阿拉斯加法律限制为58英尺(17.68米)，以便更精确的管理捕鱼效率。船的特点为甲板长而整洁，吊杆上装有动力滑车，渔网堆积在船后方，船行驶时会看到小动力艇被驮在船尾甲板上。 进行捕捞作业时当然也是很容易识别的，水面飘着一圈浮球，有小动力艇协助作业。

围网捕捞的鲑鱼被整条运往购买站和罐头厂，制成罐头产品和冷冻产品。鲱鱼被运到加工厂，剥下鱼卵，或者包装后作为其他商业渔场的鱼饵（供给其他商业渔场作为鱼饵），如长线钓渔场和螃蟹养殖场。腌鲱鱼卵，英文叫"kazunoko"，被运往日本，在当地被视为价格昂贵的美味佳肴。

【Gillnetter】

Gillnetters catch salmon—primarily sockeye, chum, and coho—by setting curtain-like nets perpendicular to the direction in which the fish are travelling as they migrate along the coast toward their natal streams. The net has a float line on the top and a weighted lead line on the bottom. The mesh openings are designed to be just large enough to allow the male fish, which are usually larger, to get their heads stuck, or gilled, in the mesh. Much larger fish and the smaller females are not so readily gilled. Gillnets work best in silty or turbid water which makes them difficult for the fish to see. Gillnet vessels are usually 30 to 40 feet long. They are easily recognized by the drum on either the front, a bow picker, or the stern, a stern picker, on which the net is rolled. Net retrieval is by hydraulic power which turns the drum. Fish are removed from the net by hand, picking them from the mesh as the net is reeled onboard. Gillnet-caught salmon are usually iced and delivered to buyers and cold storages. Historically, their ultimate destination was the canned market, though a growing market for frozen product has developed overseas.

Setnetting is a small-scale type of gillnetting done by hand from a skiff or from shore, usually by local families. There are no hydraulics. Nets are fixed and are held onshore or offshore with anchors.

Skiffs are used to set nets—one end on shore, other anchored off shore. Sometimes both ends are in the water most of the time and when a cork bobs the fish is pulled out. After salmon are picked from nets they are iced down and delivered to large collection boats, called tenders.

【刺网船】

刺网船用于捕捉三文鱼，主要是红鲑、狗鲑和银鲑。当鱼沿着海岸向出生的河流迁徙时，设上窗帘状的网，使之与鱼的迁徙方向垂直。网的顶端有浮绳，底部有沉重的铅绳。雄鱼体型相对较大，网孔大小经过设计，刚好可以卡住雄鱼的头或腮。再大的鱼或体型相对较小的雌鱼不太容易被卡住。刺网在有淤泥或浑浊的水中使用效果最好，不容易被鱼发现。

刺网船一般30到40英尺长，船头或船尾有一个滚筒，上面卷着渔网，很容易辨认。滚筒在船头的船叫做"bow picker"，滚筒在船尾的叫"stern picker"。这种船靠液压动力转动滚筒来收网。网收到船上后，需手动把鱼从网眼上摘下来。刺网捕捞的三文鱼一般被冰冻后发给买家和冷库。以往这些鱼最后会被送到罐头市场，尽管冷冻产品市场已扩展到海外。

定网捕捞是一种小规模的刺网捕捞，一般由当地家庭从海岸或者小艇上手工作业，不使用液压装置。渔网由锚固定在近海或者陆地上。

定网用小艇设置。网的一端设在岸上，另一端用锚设在海上。有时，网两端大部分时间都在水里，当网上的软木塞上下跳动时，鱼就被拖出来。人们将鲑鱼从网上摘下后，用冰覆盖，交给叫做tender的大型收集船

【Troller】

Troll vessels catch salmon, principally Chinook, coho, and pink salmon, by “trolling” bait or lures through feeding concentrations of fish. The word troll comes from a medieval German word, trollen, and refers to the revolving motion of the bait or lures used in this type of fishing. Typically, four to six main wire lines are fished, each of which may have up to a 50 pound lead or cast iron sinker or cannon ball on its terminal end, and 8 to 12 nylon leaders spaced out along its length, each of which ends in either a lure or baited hook. To retrieve hooked fish, the main lines are wound about small, onboard spools via hand crank (hand trollers) or with hydraulic power (power trollers), and the fish are gaffed when alongside the vessel. The leaders are then rebaited and let back down to the desired depth(s). Troll vessels come in a variety of sizes and configurations, ranging from small, hand troll skiffs to large, ocean-going power troll vessels of 50 feet or more in length. Troll salmon fishermen operate throughout Southeast Alaska in both state and federal waters. The troll salmon fishery produces a low-volume, high-quality product. Troll-caught salmon are dressed at sea and sold either as a fresh or frozen product. High-end grocery stores and fine restaurants are the final destination.

【拖钓船】

拖钓船用于捕捉鲑鱼，主要为奇努克鲑，银鲑和粉鲑。捕捞方式是拖着鱼饵穿过鱼群集中进食处。"Troll"这一单词来源中世纪德国词语"trollen"，指的是这种捕鱼方式中，诱饵旋转的动作。一般来说，拖钓船用到四到六根主钢丝绳。每根钢丝绳末端有重达50磅的铅锤或铁锤（像加农炮弹一样），每根绳上沿纵向间隔放置8至12条尼龙导线，每条导线末端是诱饵或饵钩。通过手摇曲柄或液压动力转动船上的小卷轴，把主绳卷起来，以回收上钩的鱼。手摇的叫hand trollers，液压的叫power trollers。鱼到船边时就被钓上来了。之后给导线重新装上鱼饵，放回到需要的深度。拖钓船有各种尺寸和结构，小到装有手摇卷轴的小动力艇，大到50英尺或更长的大型液压卷轴远洋船。渔民拖钓鲑鱼的海域遍及阿拉斯加东南部，在阿拉斯加水域和其他联邦的水域都进行作业。鲑鱼拖钓业生产的产品数量少但质量高。拖钓捕捞到的鲑鱼在海上就加工好，之后会作为生鲜或冷冻产品出售到高端食品杂货店和高级饭店。

【Trawler】

Trawlers are sometimes confused with trollers due to their similar sounding names. Trawlers typically catch large quantities of midwater species such as pollock or pink shrimp, and bottomfish such as flounder, by towing a large, cone-shaped net. Most trawl nets have doors on either side of the net’s opening to help hold it open, and some that are fished near the bottom have a heavy chain strung along the bottom of the opening to hold it close to the sea floor. The net is retrieved using huge winches and a power drum upon which the net is rolled as it is brought aboard. The end of the net, the bag or cod end, holds the fish and is usually pulled right up into the back of the vessel on a slanting stern ramp. Trawlers are generally large vesselsthe largest in the ocean pollock fishery are factory trawlers that possess onboard processing facilities. These can be up to 600 feet in length. Catches are often enormous, with a two-hour tow of the net yielding up to 100 tons or more depending on the fishery, the size of the vessel, and the concentration of fish in the area. The trawl fishery may process its catches into either fillets destined for the fresh and frozen market, or minced fish called surimi, which is manufactured into fish sticks and similar products such as artificial king crab. Shrimp fishermen sort their catches by size and species and sell the product as either a whole frozen product, or as a headed frozen product.

【拖网船】

拖网船和拖钓船因英文发音相似，有时会被人混淆。拖网船一般用于大批量捕捞中层鱼，如鳕鱼和北极甜虾(pink shrimp)，还有底层鱼，如鲽鱼。捕捞方式是拖着一个大型圆锥型网。大多数拖网两头的开口处都有装有一个“门”，帮助渔网保持张开状态。有些在水底使用的拖网，开口的底部会捆上一条很重的链子，使网底在海床上保持关闭状态。收网时，大型绞机和动力滚筒把网带到船上，再卷到滚筒上。拖网末端叫做“袋子(bag)”或者“网囊(cod end)”的部分装着鱼，一般会被拖上来，放到船后方倾斜的船尾滑道上。拖网船通常为大型船。海洋鳕鱼业中最大的拖网船是拖网工船，配有船载加工设备。这种拖网工船长度能达到600英尺(182.88米)，捕捞量非常大。根据渔场、船的尺寸和作业区域鱼聚集情况的不同，每两小时拖网作业的产出量可达100吨或更多。拖网渔场会把捕获的鱼加工成生鲜或冷冻市场所需的鱼片，也可加工成鱼糜，英文叫"surimi"。鱼糜可以制成鱼条和类似产品，比如人工帝王蟹。捕虾的渔民会根据尺寸和品种把捕到的虾分类，制成整条冻虾或去头冻虾进行出售。

【Jig Fisher】

Commercial jig fishing, also known as automated handlining, is a method of fishing using hooks with lures which are jigged up and down in the water. Jigs create a jerky, vertical motion, unlike spinnerbaits which move through the water horizontally. The jig is very versatile and can be used in both salt water as well as fresh water. Jig fishing techniques have been used for centuries by European vessels fishing Icelandic, Newfoundland and North Sea fishing grounds. Many of the techniques used then are still in use today.  In recent years however, the advent of hydraulic or electric automated jigging machines has eliminated much of the manual labor required to haul fish from great depths. Modern automated jigging machines are equipped with a computerized motor which enables the machine to automatically haul in the catch when a specified weight of fish is hooked. This improves the efficiency and accuracy of the fishing system, and also reduces bycatch and discards. You are effectively catching a quality fish straight from the sea. Jig fishing is also extremely beneficial in the face of increased fuel costs as boats actually fish with the engine switched off.

【滚钩船】

商业滚钩捕捞，又称自动化捕捞船？？(automated handling)，是一种在水中上下快速震动饵钩的捕捞方式。滚钩能创造出垂直方向上的快速运动，不像旋转饵一样在水中水平运动。滚钩比较全能，即可用于海水也可以用于淡水。欧洲渔船在冰岛，纽芬兰和北海渔场中使用滚钩捕捞技术已有好几世纪了。当时的许多技术现今仍在使用。

然而在最近几年，液压和电力自动滚钩机的出现，取代了大部分深海捞鱼所需的体力劳动。现代自动化滚钩机配备计算机化发动机，一定重量的鱼上钩后，机器会自动把鱼拖上来。这种方式提高了捕捞系统的效率和准确性，也减少了副渔获和废弃品。你可以直接从海里高效捕捞到高品质的鱼了。

面对燃油费用的上涨，滚钩捕捞也极为有利，因为滚钩捕捞时，渔船引擎实际上是关掉的。

【Crabber】

Crabbers target Dungeness, king, and snow crab using twine or wire-meshed steel pots (traps). Baited with herring or other fresh bait, the pots are left to soak for several days. A line extends from each pot to a surface buoy that marks its location. There are several configurations for the pots, though in general, the smaller round pots are fished for Dungeness in shallow bays and estuaries, and the large, heavy, rectangular pots are fished in waters deeper than 100 feet for king and Tanner crab. A power winch is used to retrieve the pots. Once aboard, a pot is opened and the catch sorted. Females and undersized males are discarded alive over the side and legalsized males are retained in aerated seawater tanks. Crab boats come in a variety of shapes and sizes, from aluminum skiffs with outboard motors that fish the inside waters for Dungeness, to seagoing vessels of 100 feet or more that ply the Bering Sea and the Gulf of Alaska for king crab. Unless one happens to see a crabber headed for the fishing grounds with its decks stacked with pots, identification of a vessel as a crabber might be difficult for the casual observer. Crabs are delivered live to shore stations where they are cooked and then either canned or sold as a fresh or frozen product. A small number are sold live in local markets through retail outlets that have circulating seawater holding tanks.

【捕蟹船】

捕蟹船用麻绳或金属丝编制的铁笼(陷阱)捕捞珍宝蟹，帝王蟹和雪蟹。笼里装上鲱鱼或其他新鲜的鱼饵，浸到水里放几天。每个捕蟹笼上有一条线，与水面浮标相连，以标记笼的位置。蟹笼有好几种规格，不过一般小的圆形蟹笼用来捕捉浅水湾及河口的珍宝蟹，大而重的长方形蟹笼用来捕捉水下100英尺深的帝王蟹和石蟹【161205本小句改为：又大又重的长方形蟹笼放在水下100米英尺深，钓帝王蟹和石蟹】。蟹笼由动力绞盘收回。一收到船上，人们就将蟹笼打开，将捕获物分类【161205本句改为：蟹笼一旦收上来，人们就将其打开，并把捕获物分类。】。母蟹及尺寸过小的公蟹被活着丢到船外【161205本句改为：母蟹及尺寸不符合法律规定的公蟹被活着丢到船外】。尺寸合适的公蟹留到充气海水池里【161205本句改为：尺寸合法的公蟹留到充气海水池里】。捕蟹船有各种形状和尺寸，小到铝制尾挂机小艇，大到100英尺及更长的航海船。铝制尾挂机小艇在内部水域捕捞珍宝蟹。航海船则到定期行驶到白令海和阿拉斯加湾捕捞帝王蟹。外行一般很难识别一艘船是否为捕蟹船，除非碰巧看到它甲板堆满笼子驶向渔场【161205本句改为：捕蟹船不仔细看一般是看不出来的，除非是它甲板上堆满笼子驶向渔场的时候恰好让人看见了。】。活蟹会被运到岸上的加工站，在这里做熟后，加工成罐头，或者作为生鲜产品或冷冻产品出售。还有一小部分，通过拥有循环海水池的零售商店，活着卖到当地市场。

【Longliner】

Longliners catch bottomfish, primarily halibut, blackcod, lingcod, and rockfish, via a long line that is laid on the bottom. Attached are leaders or gangions with baited hooks. Each longline can be up to a mile in length and have thousands of baited hooks. The lines are anchored at each end of each set. Lines at the ends run to the surface and are marked with a buoy and flag. A longline vessel typically sets several lines for a 24-hour soak. The lines are retrieved over a side roller with a power winch, and the fish caught are bled or dressed and then packed in ice in the vessel’s hold. Longliners are typically large vessels, 50 to 100 feet in length, with a weather cover on the stern to protect the crew. The longlines are coiled and stacked on deck in tubs when not in use. Most vessels in this fishery can pack 20 to 40 tons or more of iced product before returning to port. Longliners are readily identified by their weather cover and, when not fishing, by the numerous orange buoys and flags that are tied along their rails. This fishery delivers its catch whole and bled (rockfish), or whole and gutted (halibut), or headed and gutted (blackcod and lingcod) for subsequent sale to fresh and frozen markets.

【长线钓船】

长线钓船捕捞底层鱼，通过放置在水底的长钓线，主要捕捞大比目鱼，黑鳕，中巨石斑鱼(lingcod)，和岩鱼。长钓线上系着带有饵钩的导线或者钓钩线。每条长钓线长度可达一英里，带有几千个饵钩。每套长线钓装置的每个尾段都有以锚补丁的长钓线。最末尾的长钓线浮在水面，用一个浮标和一面旗做标记。一艘长线钓船通常设置好几条钓线，浸在水里24小时。钓线通过动力绞盘收到船侧面的滚筒上去，捕到的鱼被放血或者加工处理，然后放到船舱内的冰里。长线钓船通常是较大的船，有50到100英尺长，船尾有防雨罩，用来保护船员。长钓线不用的时候，卷成卷堆放在甲板上的桶里。大部分从事长线钓业的船，在回港前能装20到40吨或更多的冷冻产品。长线钓船很容易识别，船上有防雨罩，不作业时，船舷的栏杆上拴着无数的橙色浮标和棋子。长线钓业运输的鱼，后续会销售到生鲜和冷冻市场。石鱼放血后整条出售，大比目鱼去掉内脏后整条出售，黑鳕和中巨石斑鱼去头去脏后出售。

国内生产钢丝绳品种如下： 1.磷化涂层钢丝绳（中国专利），钢丝经锰系、锌锰系磷化处理，钢丝的耐磨性、耐蚀性全面跃升，不易磨损、不易锈蚀使钢丝绳疲劳寿命超大幅度提高，疲劳寿命是同结构光面钢丝绳3-4倍（试验室可比条件下），远超进口钢丝绳，建议自己做对比疲劳寿命测试，磷化涂层钢丝绳正在全面取代各类光面钢丝绳，也可替代先镀后拔薄锌层镀锌钢丝绳使用（可通过盐雾试验检验耐蚀能力），使用寿命更长，单位使用成本更低，质量稳定性可靠性更佳，按照现在钢丝绳市场的大致价格，锰系磷化涂层钢丝绳的价格大约是光面钢丝绳的1.4-1.6倍，而使用寿命延长幅度远高于价格的增长幅度，所以，磷化涂层钢丝绳日均使用费用仅为光面钢丝绳的30-45%，使用成本更低，性价比更高。

2.镀锌钢丝绳，包括热镀锌和电镀锌两种，一般热镀锌锌层厚，电镀锌锌层薄

3.不锈钢丝绳，以304或316不锈钢为主，防腐蚀效果非常优秀但是价格昂贵

4.涂塑钢丝绳，碳素钢丝绳基础上，外层涂覆聚乙烯、聚丙烯或尼龙

5.光面钢丝绳，使用寿命短，市场需求剧减，将被磷化涂层钢丝绳全面淘汰。

6.海洋工程系泊用钢丝绳

7.缆索钢丝绳

大气环境中使用的起重机械，优选锰系磷化涂层钢丝绳，重腐蚀环境优选热镀锌—磷化双涂层钢丝绳，海水中优先海工钢丝绳。采购时请注意，在购货发票必须注明钢丝绳名称，如磷化涂层钢丝绳或316不锈钢丝绳，防范不法企业侵害自身合法权益，另外，专利产品一般在钢丝绳外包装上有专利号喷涂标注，质保书应有主要技术指标，如磷化膜种类和膜重（磷化膜膜重大小、耐磨性、耐蚀性等对钢丝绳使用寿命有重要影响），仅供参考。

中国年产180万吨钢丝绳居世界第一，钢绳主要品种如下：

1.磷化涂层钢丝绳（专利技术），钢丝经锰系或锌锰系磷化处理，钢丝耐磨性、耐蚀性全面跃升，磷化膜与润滑脂的复合作用，有效抑制微动磨损的发生，疲劳寿命是同结构光面钢丝绳3倍左右，可通过疲劳试验验证疲劳寿命（亲自做疲劳试验最具可信性），是光面钢丝绳的升级换代产品，也可替代先镀后拔薄锌层镀锌钢丝绳使用（可通过盐雾试验检验或对比耐蚀能力），使用寿命更长，使用成本更低，稳定性更佳。

2.镀锌钢丝绳，包括热镀锌和电镀锌两种，一般而言，热镀锌锌层厚，电镀锌锌层薄

3.不锈钢丝绳，以304或316不锈钢为主，防腐蚀效果非常优秀但是价格昂贵
