后現代課程研究興起於70年代的概念重建活動,概念重建旨在使課程研究從一個本質是技術性的、實踐導向的、 「非理論」的和「非歷史」的領域轉變為一個理論化的、概念自主的,本質上是歷史的、個體的和運動變化的領域。Standard practice for continued airworthiness system for light sport gyroplane aircraft

通常恆星的自轉軸和磁軸並不一致,中子星亦不例外,所以沿著磁軸向外發射的無線電波束,在中子星自轉的帶動下,便會如燈塔般向宇宙掃射,這便是著名的A few decades ago it was discovered that the rotational velocity of the earth undergoes small variations.
幾十年前,人們發現地球自轉的速度有微小的變化。Venus has the distinction of spinning "backward" on its axis.

自轉的改變則因為月球產生的潮汐力,以及因地球外核液體攪動和大氣蒸發循環(赤道蒸發的水氣于地極凝結成冰,並周期性融化)產生的慣性效應。In the motion, the direction of angular momentum vector changes every moment, because there is a torque caused by gravity act on the wheel, then the wheel rotate itself and rotate around the fixed point
車輪進動實驗:在進動中,角動量的矢量方向不斷改變,是因為受到一個由重力產生的力矩,使車輪在自轉的同時又繞支點轉動。A person who lives at the equator is in accelerated motion due to the earth's rotation.
一個居住在赤道的人由於地球自轉的緣故是作著加速運動的。The period during which a celestial body makes a similar rotation

原因是:為了讓歷法配合上地球自轉的腳步,我們得多加一秒鐘。The rotation of the original gas and dust cloud becomes the revolutions of the planets around the sun and the rotation of the sun itself
氣體塵埃雲原先的轉動,成了行星公轉和太陽自轉的原動力。整個過程大約用了That is, it moves above the equator at the same rate as the earth s rotation so that all the time it is above the same geographical area on the earth
它環繞地球的速度與地球自轉的速度相同,固它在任何時刻均逗留在地球上同一地點的上空。One reason is the change of interior convection zone with spectral type produce the phenomena ; another reason is the differential rotation of f type stars exist a upper limit
這一拐點的出現可能是f型主序星的對流區的變化影響形成的,也可能是f型主序星在f5附近存在較差自轉的上限形成的。Under the circumstances that the ball rubs the pot to revolve round the sun on the function with high - speed rotation, ball rub to grind ball form to supplies heavy high frequency strike, grit strength very under function of mass force pot, grind or mix fast the supplies
