摘要
船舶磁罗经是重要的助航仪器,其剩余自差过大时(一般指50以上时)对船舶安全航行的影响应该引起高度重视。船舶磁罗经自差的主要来源是B/λH和C/λH等两个半圆自差力对罗盘磁针的作用,采用"人为航向法"消除磁罗经自差,对于中小型船舶来说是一种既简捷又实用的有效方法。
Magnetic compass is important navigational aid for Three Gorges dam ship. We must pay great attention to the influence on shipping safety when its surplus deviation is oversized （Generally refers to above 50）. The main origin of magnetic compass deviation is fromthe effects on compass magnetic needle produced by two semicircular deviating force , which include B＇λH and C＇λH and so on . The artificial direction method is a simple and practical method of eliminating the magnetic compass deviation for Three Gorges dam ship.
