heliocentric coordinates-
For the regular curves, we find two killing fields for the purpose of integrating the structural equations of the p - elastic curves and express the p - elastica by quadratures in a system of cylindrical coordinates. for the star - like affine curves, we solve the euler - lagrange equation by quadratures and reduced the higher order structure equation to a first order linear system by using killing field and the classification of linear lie algebra sl ( 2, r ), sl ( 3, r ) and sl ( 4, r ). we solve the centroaffine p - elastica completely by quadratures
對于正則曲線的情形，我們發現了兩個用於求解p -彈性曲線的結構方程的killing向量場並用積分將p -彈性曲線在一個柱面坐標系中表示出來，而對仿射星形曲線的情形，我們用積分方法解出了歐拉-拉格朗日方程，利用killing向量場及線性李代數s1 （ 2 ， r ） 、 s1 （ 3 ， r ）和s1 （ 4 ， r ）的分類將高階結構方程降為一階線性方程，因此我們用積分完全解出了中心仿射p -彈性曲線。The 29 f globular clusters in the galaxy are selected as samples in my paper ( the space distribution and motional orbits of the samples have not been researched in detail before. ). according to the basic parameters : azimuth coordinates, distances from the sun, radial velocities and proper motions of sample clusters, the initial positions and velocities of the samples are reduced using the galactic coordinates, and their orbits are integrated by numerical method for three different galactic gravitational potential models
本文選用銀河系中29個累積光譜型為f型的球狀星團作為樣本（這些樣本星團的空間分佈和運動特徵都沒有被詳細地討論過） ，根據它們的基本資料：方位坐標、日心距、視向速度，絕對自行等參數，歸算處理得出了各樣本星團的空間分佈和運動速度。It has set up physical chemical inspection center, 3 - d coordinate meter lab aberlink, made in england, helium leakage indicator lab shimadzu, made in japan, ultrasonic crack detector lab, x - ray fault indicator lab

他心裏打算晚上出門時順便去找她，但是當他坐上街車往西去時，他把這事兒壓根忘了，一直到夜裡看晚報時，才想起自己該干沒乾的事。報上在秘密會社通知的標題下有一條三行的小消息。消息說，兄弟會寇斯特支部將于日在阿佛萊禮堂演出，屆時將上演煤氣燈下一劇。Taking account of the perturbation of the earth ’ s shape, the gravitation of the sun and the moon, the radiation pressure from the sun light and atmosphere drag, a precise orbital dynamic model of spacecraft is established in the equatorial geocentric inertial coordinate system ( j2000 )
考慮了地球形狀攝動、日-月引力攝動、太陽輻射壓力和大氣阻力因素對飛行器的影響，在地心赤道慣性坐標系下建立了精確的軌道動力學模型。分享友人
