纵观世界各国的城市化率达到50%左右时,伴随着经济高速发展的往往是社会矛盾的集中爆发中国正处于这一城市社会来临的关键节点,整个国家在政治、经济、社会等方面都面临结构性转变通过截取8个典型国家城市化率达50%的发展断面,从经济、社会和空间三个层面进行比较研究,分析了不同时期不同背景下各国城市发展特征和城市问题的异同点表明快速城市化阶段的核心问题是以公平为导向的社会活动和以效率为导向的经济活动之间的博弈,并且以城市化率50%为拐点,其隐性关键词从前期的"牺牲"逐渐转向后期的"反哺"。快速城市化阶段的终极理想理应是获得城市综合品质持续不断的增量,而经济效率与社会公平的动态平衡可视为动力调节的过程。

The operator operations between the disturbing potential and the geoidal undulation, the gravity anomaly, the deflection of the vertical are defined based on the relations among the gravity potential, the normal gravity potential and the disturbing potential. With the sphere as the boundary surface, based on the solution of the external boundary value problem for the disturbing potential by the spherical harmonics in the physical geodesy, the general inverse Stokes’ formula, the general inverse Vening-Meinesz formula and the general Molodensky’s formula are derived from the operator operations defined. The general formulae can get rid of the restriction of the classical formulae only used on the geoid. If the boundary surface is defined as the geoid, the general formulas are degen- erated into the classic ones.
