To higher the model’s precise, some sequential data are processed by slide mean value, a Maclourin Exponsion is made to some exponents of less adaptable response function and acceptance or rejection is made according to the fitting mode of the number series and their development. In the quatitative analysis, the first locus of the developing coefficient of the model in the sports field is the main basis. The analysis indicates that women’s and men’s field sports in Asia are developing respectively much faster, a little faster than that of the world, but men’s track sports in Asia are progressing paralled to that of the world, and women’s track in Asia remains behind.展开更多

文摘By establishing grey dynamic model and adopting its method, this essay makes forecast and comparison on the developing trend in track and field sports of Asia and the world. To higher the model’s precise, some sequential data are processed by slide mean value, a Maclourin Exponsion is made to some exponents of less adaptable response function and acceptance or rejection is made according to the fitting mode of the number series and their development. In the quatitative analysis, the first locus of the developing coefficient of the model in the sports field is the main basis. The analysis indicates that women’s and men’s field sports in Asia are developing respectively much faster, a little faster than that of the world, but men’s track sports in Asia are progressing paralled to that of the world, and women’s track in Asia remains behind.
