罗盘

The mathematic model of the single degree of freedom gyrocompass under electromagnetic bearings is given and the influences on the north finding accuracy and orientation time caused by the declination of the gimbal axis under elastic magnetic bearings are discussed.

提出了一种结构简单的新型磁悬浮寻北仪，建立了电磁轴承约束的单自由度陀螺罗盘的数学模型，讨论了陀螺框架轴在弹性约束下偏离铅垂方向对寻北精度及定向时间的影响。

A compass is ruled by the magnetic force of the Earth.

罗盘受地球磁力的控制。

The iron in the ship caused a deviation of the magnetic needle of the compass .

由于船上的铁，导致了罗盘上磁针的偏离。

One of you asked this question."Does a magnetic compass point to the North Pole?"

前段时间有观众向我们提问："罗盘的指针真的指向北极吗？"

Magnetic north; the needle of a magnetic compass points to the magnetic north pole.

磁北；罗盘上的指针指向北方。

The needle of a magnetic compass points to the magnetic north pole.

磁性罗盘上的指针指向北方磁极。

Since then, people began to analyze why the compass pointer will be a departure from the magnetic North Pole, and will be divided into several categories of reasons.

从那时起，人们就开始分析罗盘指针为何会偏离磁北极，并且将原因分成几类。

In the form of a card that rotates so that 0 degrees or North points to magnetic north.

一种旋转的像罗盘的片状指南针，所以零度或北方能够指向磁北。

A needle that points to magnetic north.

指指南针，罗盘的意思。

The effect of the magnetic interference on the output of magnetic compass was analyzed and a ellipse model for the compass deviation was established. By analysis on the singularity of a coefficient matrix, the error coefficients of the ellipse model were identified by the least square ellipse fitting method.

分析了外界磁干扰对磁罗盘输出的影响，建立了罗差的椭圆模型，通过对系数矩阵的奇异性进行分析，采用最小二乘方法实现了对椭圆模型误差系数的辨识。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
