1.The benefit of this cooperation has been that archaeoastronomy has expanded to include the interrelated interests in ancient and native calendar systems, concepts of time and space, mathematics, counting systems and geometry, surveying and navigational techniques as well as Geomancy - Dowsing - and the origins of urban planning.
该合作的好处就是考古天文学已经扩展了包括古代和本土日历系统、时间空间概念、数学、计算系统和几何学、测量和航海技术以及泥土占卜相关的兴趣-探寻水源和矿藏-和城市规划的由来。收藏指正
2.This paper extends the T route counting of two-dimensional perpendicular space to the T route counting of n dimensional perpendicular(oblique) space(k≤n), and gives some concree formulas of counting when n=3,k=2,3; and gives some new geometry (combination) explanation of Catalan number.
本文将二维直交空间中的 T路计数问题推广到 n维直 (斜 )交空间中 k( n)向 T路计数问题 ,并给出 n=3,k=2 ,3时的一些具体计数公式 ,同时给出了 Catalan数的几个新的几何 (组合 )解释收藏指正
