The result shows: each index score of the two groups of athletes is improved after training,but the characteristics of employing forces and the way of muscle work in one leg jumping exercises such as the one leg jump and step are much closer to sprint techniques. And using this kind of methods can effectively develop the special quality of juvenile sprinter.展开更多

Tax revenue flexibility is a main index which reveals the whole country's burden on the main macro-economy. The paper did an empirical research on national tax revenue flexibility in Chongqing from the total and structural perspectives, and it shows that there are some fluctuations during 2005-2009, which are still within a normal range. Tax revenue promotes Chongqing's economic growth.展开更多
