| 摘 要： | 一、前言 我们知道对磁罗经自差的校正,过去虽有人提过多种多样的方法,但把他们归结起来,实只有以偏转仪测量力的校正法和以方位仪观测方位的校正法两种而已。用偏转仪来校正自差是在四个基点上进行工作的,而对于在四个隅点上是否可行,过去尚没有人提到过;用方位仪观测方位来校正自差需在四基点及四隅点上来进行,光在四隅点上来进行校正,过去也没有人提到过。但由于消除区的航道关系,往往有这样的情况,即在基点上航行有困难,而在隅点航向上航行却很方便。因此,我认为我们必须来研究一下,在隅点上校正磁罗经自差是否可能。经过研究与实验证明了在隅点上校正自差不但完全可能,而且还有一些优点。现将其理论分析与实际操作方法说明如下。

| Abstract: | Up to now no investigations have been made into any method of adjusting magnetic compass deviations on inter-cardinal points, though many methods of adjusting on cardinal points have been advanced and adopted.In some waterways it is very difficult to steer a ship's head on cardinal points, but to do so on inter-cardinal points is very easy. It is, therefore, necessary to recommend a method of adjustment to compass-adjusters to compensate magnetic deviations on inter-cardinal points.After making a study of t... |
