【摘要】："更数"是计量航海时代标示航线的两个基本要素之一,其准确与否关乎远洋航海的成败。"更"是计时单位,被用于推算航程,在"标准航速"下,一更约可航行六十里。"更"的概念萌芽于南宋,元代经民间火长使用、推广,至明代普遍应用于远洋航海。《海道针经》所载更数,应是在"标准航速"下从甲地航达乙地所用时间。不同的海道针经所载更数存在差异。每次航行,火长均需根据实测航速重新推算更数。南海《更路簿》与《海道针经》一脉所出,但有自己的特点。
[Abstract]:"more numbers" is one of the two basic elements in measuring the marked routes of the navigational age, and its accuracy is related to the success or failure of ocean navigation. " "more" is a unit of timing used to calculate a voyage. Under "standard speed," one shift can sail about 60 miles. " The concept of "more" originated in the Southern Song Dynasty, and was widely used by the people in the Yuan Dynasty, and was widely used in ocean-going navigation by the Ming Dynasty. The number contained in the Seadao Needle Sutra should be the time taken to sail from place to place under the "standard speed". There are differences in the number of more contained in different Seadow Needle channels. For each voyage, the fire length should be recalculated according to the measured speed. The Nanhai Gan Road Book and the Seado Needle Channel come out of one vein, but have their own characteristics.
