These nonlinear chaos dynamitic models forecast oil consumption quantity of China. In this dissertation, it has mainly studied the fractural dimension measure to petroleum economics system, the phase space reconstruction modeling and prediction techniques to economic chaotic time series. It puts forward chaos dynamitic models, which are forecasting model for oil consumption. Corresponding countermeasures of the oil supply-security of China are suggested by analyzing the forecasting results and the problems existing in petroleum economic system of China, especially aiming at the balance between oil production and consumption quantity.

According the experiential formulas of headbox to design the stepped diffuser headbox's geometry parameters. Supposing Paper suspension flow as potential flow and basing on hydrokinetic and computational fluid dynamics theories, we can solve the elliptoid partial differential equations which are followed by the flow functions and the potential functions by finite element method and simulate the flow's speed distribution with pde toolbox of matlab software. The simulate results and the flow analysis have good precision.
