| 1. | Because of its oblate shape, the moment of inertia of the earth is a maximum about the polar axis and minimum about an axis in the equatorial plane .
由于地球是扁球体，绕极轴惯量矩最大，而绕在赤道面内的轴的惯量矩最小。 |
| 2. | from the standpoint of the gyrocompass the earth appears to be rotating about an axis making an angle ε with the true polar axis.
从陀螺罗盘的位置观察地球，好象地球是绕着偏离其极轴角的一个轴在移动。 |
| 3. | The alignment of the polar axis and the monitoring of the guiding process require absolute accuracy
极轴的摆放及追踪过程必须十分准确。 |

< uk >从陀螺罗盘的位置观察地球，好象地球是绕着偏离其极轴角的一个轴在移动。 < / uk > |
| 5. | The polar axis should point to the celestial pole around which all stars seem to rotate and the elevation of the axis should be the same as the latitude of the location
赤道仪的极轴必须对准星空的转动中心，而仰角则相等于拍摄地点的纬度。 |
| 6. | But the shape and size of pollen , length of p and e , width of net lines , size of net aperture , net porosity among different materials were different
而花粉的形状大小、极轴长和赤道轴长、外壁纹饰中的网脊粗细、网孔大小、孔频等随材料不同而异。 |
| 7. | The angular extent in a specified plane which contains all the radius vectors of the polar curve of luminous intensity having lengths greater than a specified fraction of the maximum
在某一平面上，一定角宽范围内所包含的光强极轴曲线上的矢径长度均大于其最大值的某一特定比例，这种情况定义为光束的发散。 |
| 8. | Instead of assuming the earth to be a perfect sphere , this function takes into account the actual polar flattening of the earth and the equatorial bulge , which gives a much more accurate computation between the given coordinates
它没有假设地球是一个完整的球面，而是考虑了地球的极轴扁平率和赤道鼓起率，这样就给出了两个坐标间更精确的距离。 |
| 9. | At present mounts of optoelectronic measurement system have mainly two kinds of frame , i . e . altitude - azimuth form and equatorial form . the vast majority of large telescopes built are of an altitude - azimuth pedestal design in order to track fast moving satellites
陆基型光学测量设备目前主要采用地平式和极轴式两种结构模式，由于地平式系统成本低，软硬件成熟度和工作可靠性高等原因，在观测人造卫星的仪器中绝大部分采用地平式装置。 |
