earth axis 中文意思是什麼
earth axis
解釋
地球旋轉軸[座標系-
The prime meridian, which runs through greenwich in south - east london, became the basis for the world ' s time keeping in 1884 after the first astronomer royal, john flamstead, calculated that the earth rotated on its axis once every 24 hours
1884年，首位皇家天文學家約翰法蘭姆斯坦算出地球每隔24小時繞軸自轉1次，使得通過倫敦東南格林威治的本初子午線成為全球計時基準。 -
The earth rotates once a day on its axis.
地球繞它的自轉軸一天旋轉一周。 -
The earth revolves both round the sun and on its own axis.
地球既公轉又自轉。 -
The earth revolves both about the sun and on its own axis.
地球又公轉又自轉。 -
The earth is nonspherical and has a tilted axis.
地球不是球形的並有一傾斜的轉軸。 -
Birds and compasses know north from south because, like a giant bar magnet, the earth ' s magnetic field has two poles that line up closely with the planet ' s axis of rotation
候鳥與指北針都知道何為北方、何為南方，因為地球就像一條巨型磁鐵棒，它的磁場有兩極，且這兩個地磁的磁場線和地球的自轉軸非常接近。 -
From the standpoint of the gyrocompass the earth appears to be rotating about an axis making an angle ε with the true polar axis.
從陀螺羅盤的位置觀察地球，好象地球是繞著偏離其極軸角的一個軸在移動。 -

The rotation of the core generates the magnetic field of the earth. the magnetic axis does not coincide with the spin axis and it does not pass through the earth s center
地心的旋轉產生了地球的磁場，有趣的是，磁軸不單和地球自轉軸不一致，而且並不穿過地球的中心。 -
Elastic earth model ; precession nutation moment ; cip axis
彈性地球模型歲差章動力矩cip軸 -
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.
由於地球是扁球體，繞極軸慣量矩最大，而繞在赤道面內的軸的慣量矩最小。 -
The approach of obtaining the guidance coefficients can be utilized in the situations in which more than four coefficients are hired for guidance to enhance the guidance performance. in addition, more precise earth model, which is non - spherical and will circle around its body axis, can be considered, and this will lead to more true results
最後，本文對進一步的工作提出了建議，認為可以考慮用四維以上的制導參數確定反饋增益系數以改善其制導性能，另外，可以進一步考慮地球旋轉時影響飛船再入段縱程的因素，使得擬合結果更接近實際情況。 -
I fancy d i could make all but the wheel, but that i had no notion of, neither did i know how to go about it ; besides i had no possible way to make the iron gudgeons for the spindle or axis of the wheel to run in, so i gave it over, and so for carrying away the earth which i dug out of the cave, i made me a thing like a hodd, which the labourers carry morter in, when they serve the bricklayers
可做輪子卻不那麼容易，我簡直不知從何處著手。此外，我也無法做一個鐵的輪子軸心，使輪子能轉動。因此，我決定放棄做輪子的念頭，而做一個灰斗似的東西-就是小工替泥水匠運泥灰用的灰斗，這樣就可把石洞里挖出來的泥土運出來。 -
Listen, it has something to do with the earth ' s axis
這和地球的旋轉軸有關 -
Locations on the earth's surface are specified in terms of the earth's axis of rotation.
地面的定位是沿著地球的自轉軸而定的。 -
The tilt of the earth's axis, not the shape of its orbit, is what is responsible for the seasons.
形成季節的主要因素不是地球公轉軌道的形狀，而是地球自轉軸的傾斜。 -
For the earth, the rotational axis tilts 23. 5. as a result, there is no seasonal change in venus
地球的自轉軸傾角為23 . 5 ，所以金星並沒有四季之分。 -
As the earth spins on its rotation axis, it wobbles like a top, slowly swinging the northern hemisphere closer to and then farther from the sun
當地球自轉時，自轉軸會像陀螺一樣晃動，因此北半球與太陽的距離會逐漸接近，繼而遠離。 -
Since the rotational axis of the earth is tilted from the revolution axis by 23. 5, the sun, for example, rises at different directions at different times during the year
由於地球的自轉軸相對于公轉軌道平面傾斜了23 . 5度，再加上地球的繞日運動，所以太陽東升的方位角會隨日子改變。 -
Mechanism transmission device include main motor, main reducer and transmission earth axis
2機械傳動裝置包含有主電機、主減速箱、傳動地軸等。
