法顿是什么?

A fathom is a unit of length in the imperial and U.S. customary systems used primarily for measuring water depth. One fathom is equal to 6 feet or 1.8288 meters exactly. The term "fathom" comes from the Old English word "fæðm," meaning "embracing arms" or "outstretched arms," referring to the distance between a person's fingertips when their arms are stretched out to the sides.

历史意义

法特荷自古就被作为深度测量的海洋单位. 这对水手来说是一个实用的单位,因为他们可以通过延长手臂迅速估计出一个法特奥. 在早期通航和航海中,这种人尺度的测量使得航海家在没有专门设备的情况下可以确定深度.

The Ancient Greeks had a similar measurement called the "orguia," which was also based on the span of outstretched arms. By the Byzantine period, this had evolved into two forms: a standard orguia (about 6 feet) and an "imperial" orguia that was slightly longer.

海洋应用

数百年来,法特霍姆斯一直是海上航行的组成部分,特别是:

• 深度声音:传统上,水手会使用以平相间隔标记的加权线(被称作测深线)来确定水深. 他们会降低线,直到它触及到底部,然后用线上标记来计出法特乌姆数.
• 自然图:在广泛采用测量系统之前,海图显示深度为平分。 事实上,由美国水文局制作的许多海图仍然使用法特克和脚.
• 安全导航:了解深水层的水深对于确保船只安全通行和避免水下危险至关重要。
• Anchor Rode 测量:航海家号常常用平面测量锚地线(rode),以确定安全锚地的适当范围(线长到水深的比例)。

不同类型的肥胖

纵观历史,教义有几种变体:

• 国际法顿:整整6英尺(1.8288米)
• 英国海军上将法顿:最初的定义是一海里的1/1000,约6.08英尺
• 法顿号战舰:完全6英尺,历史上被英国和美国海军使用
• 法顿号商船:历史上英国5到5到5英尺不等,直到19世纪

文学和文化法特霍姆斯

Fathom也进入了文学和流行文化:

• Shakespeare's "The Tempest" includes the famous line, "Full fathom five thy father lies," referring to a drowning at a depth of five fathoms.
• The phrase "to deep six something" (meaning to dispose of or discard something) originates from maritime burial practices, which traditionally required at least six fathoms of water.
• Mark Twain's pen name comes from the term "mark twain," which riverboat crews would call out when the water depth measured two fathoms (12 feet), indicating safe passage.

现代使用

虽然衡量系统已成为大多数测量的国际标准,但若干情况下仍然使用fathoms:

• 美国通航图仍然普遍使用深水(一般深度大于30英尺)的法特克
• 传统渔民和海员,特别是美国和联合王国的传统渔民和海员,继续使用法特克语
• 潜水社区有时在平面图中引用深度
• In cable and anchor chain measurements, where units like "shots" (15 fathoms or 90 feet) and "shackles" (12.5 or 15 fathoms) are derived from the fathom

相关营养计量

其他若干航海测量与平分法有关或源于此法:

• 电缆长度:历史上有100到120个迷宫 取决于海军
• 射击:锚链长度等于15平方英尺(90英尺)
• 摇摆:虽然1949年被英国海军重新定义为15个平面
