1. This paper analyzed the declination cause of balancing weight for multi-rope friction hoist and put forward some measures to ward off this kind of declination. 本文就多绳摩擦式提升机平衡锤偏斜的原因进行了分析，并提出了避免偏斜的措施。
2. and declination measurements are discussed when the sensor axis of fluxgate magnetometer is deviated respectively from the magnetic meridian and horizontal plane. 本文讨论了磁通门式磁力仪探头轴偏离磁子午面对测磁倾角的影响和探头轴偏离水平面对测磁偏角的影响。

4. an imaginary line connecting points on the Earth's surface where the magnetic declination is zero. 一条在地球表面上连接磁偏为零的点的假想线。
5. an imaginary line connecting points on the Earth's surface where the magnetic declination is the same. 在地球表面上连结具有相同磁偏角各点的一条联线。
