主要觀點歸納如下： （ 1 ）城市旅遊是基於城市的發展而發展的，中國城市旅遊可分為古代、近代、現代和后現代四個階段，分別對應於前工業文明時期的城市旅遊、工業文明萌芽時期的城市旅遊、全面建設工業文明和后工業文明因素初露端倪時期的城市旅遊，以及邁向信息時代的城市旅遊，其間體現出不同的城市旅遊發展特徵； （ 2 ）經歷不同發展的時期，中國城市旅遊表現出如下的演進規律： 1 ）城市旅遊觀念開放程度逐漸增強，對城市旅遊的容納度日趨加大，對城市旅遊地位的認識從忽視到關注再成為生活的必要因素； 2 ）旅遊形式從單一走向多元，新的旅遊形式隨城市發展層出不窮； 3 ）城市旅遊的內外部空間聯系從封閉平面走向開放立體，達到網路化、連綿化、分區化、立體化布局； 4 ）城市旅遊支持系統從缺失走向健全，達到理性高端； 5 ）城市旅遊社會分層從森嚴走向融合，經歷了「小眾旅遊」 、 「大眾旅遊」 ，最終發展到「全民旅遊」 ； 6 ）城市旅遊產業演變態勢可以概括為一條橫臥的「 s 」曲線，表現為低開?高走?平穩發展。According to the experimental results of the four knots designed for it, we has arrived at that the dimensional angle iron framework is truly efficient to knot

小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性Cultural industries and strategies have recently constituted not only as major areas of preserving local cultural sustainability, regenerating traditional space, and revivifying urban economics, but also as a vital element of urban competitive edges in response to the deepening development of economic globalisation
