In this paper, the Adomian decomposition method (ADM) is applied to solve the fractional-order system with line equilibrium. The dynamics of the system is analyzed by means of the Lyapunov exponent spectrum, bifurcations, chaotic attractor, and largest Lyapunov exponent diagram. At the same time, through the Lyapunov exponent spectrum and bifurcation graph of the system under the change of the initial value, the influence of fractional order q on the system state can be observed. That is, integer-order systems do not have the phenomenon of attractors coexistence, while fractional-order systems have it.

The diversity of coal basins and the late intensive reformation of coal regulations are the remarkable characteristics of Chinese coalfield geology. These largely determine the searching orientation and value of coal exploitation and utilization. The coalfield structure research is one of the basic works and core contents in potential evaluation of national coal resources. In this paper, new thought of carry out coalfield structures research in potential evaluation of coal resources is introduced. The main research contents can be summarized in several aspects, including regional geological setting, structural shape and distribution regularity, tectonic origin and evaluation, structural control of coal. It briefly summarizes the working emphasis of coalfield structures research in different occurrence region of coal in our country.

Proceeding from the present research of e-commerce and the tertiary industry, setting Fujian Province as an example, conduct econometric analysis and synthesize data report to make research on the promoting role of e-commerce on the tertiary industry of Fujian Province and explore the optimization path of the regional tertiary industry from e-commerce perspective.
