lunar theory
解釋
月球運動理論-
In comparison with the classical lunar theory the motion of an earth satellite offers important practical differences.
與經典的月球理論相比較，地球衛星的運動有顯著的實際差別。 -
Now some universities and institutes of china have made some samples of the lunar rovers and theirs wheels, but until now the wheel ’ s mechanical performance is seldom researched and tested. this paper will analyze the mechanical performance of the wheel and design a test - bed to test the performance of the lunar rover ’ s wheel. firstly, the mechanical characters of the soil are separated to press - sinkage character and shear character based on bekker ’ s theory, and common press - sinkage and shear models are introduced and the theory of lankine passive earth pressure is also introduced
根據bekker半經驗法的基本思想，將土壤的力學特性分解為水平方向的剪切特性和豎直方向的承壓特性，闡述了地面力學中常見的土壤的承壓、剪切等力學模型，並引入了朗肯被動土壓力理論，為建立車輪在松軟土壤中前進和轉向的力學模型奠定了基礎，同時進行了實驗土壤的剪切實驗，測量了土壤的內聚力和內摩擦角等參數。 -
Because the only source of heat that could melt the entire moon would be a very rapid accumulation of small bodies, the presence of large quantities of anorthosite in the lunar crust supports the theory that the moon coalesced from the debris of a planetary collision
能熔化整個月球的唯一熱源是小型天體的快速聚集，因此月球地殼內大量的斜長巖支持了月球是由行星際遺屑撞擊合併而成的理論。 -
This paper briefly outlines the finding of irregularities of the lunar apparent motion & the lunar theories in history in the western world, and emphatically introduces copernicus ' s method for ascertaining numerical parameters and his lunar theory, which were adopted by xinfa suanshu
摘要在簡要介紹月亮視運動各種差的基礎上，重建《新法算書》所載哥白尼月亮模型及其確定幾何參數方法。 -
Further more, we give a detail research on arc tracking of difference steering lunar rover. and give some simulation on the base of arc tracking theory
此外，還對差速轉向月球車的路徑跟蹤演算法進行了研究，在著重分析了圓弧跟蹤演算法后，給出了相應的模擬。
