In 1978-1985, the country adjustment the development policy of the city and countryside, the key of finance and taxation policy was the farmer. In 1985-1990, the country tried hard to coordinate the contradiction of the city and countryside development and took "the Three Chooses" as a center of gravity. In 1990-2002, the disparity of the city and countryside was more and more big, the country had to standard farmer tax revenue; transform administrative fees into taxes in order to adjust the harmonious of the city and countryside relation. In 2002-2006, the country alleviated gradually the contradictory of the city and countryside through the reform of agricultural tax and administrative fees. Along with entering WTO, the uncoordinated relations of the city and countryside faced a huge challenge.

改革开放以后，国家在统筹城乡关系上经历了四个阶段：1978—1985年，国家对城乡发展政策进行调整，财税政策重点向农民倾斜；1985—1990年，国家以治理"三乱"为重心，力图协调城乡发展矛盾；1990—2002年，城乡差距越来越大，国家采取了规范农民税收、"费改税"等措施，试图调整不和谐的城乡关系；2002—2006年，国家通过农村税费改革、取消农业税等政策措施，逐步缓解了城乡矛盾。

Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关
