The financial revenue scale autoregressive model predicted 2010-2020, the scale of fiscal revenue, with Pratt ＆ Whitney type total pension should be of basic pension and substitution rate level of demand for pension accounts for fiscal revenue proportion of the international experience of fiscal income of 5% were measured and evaluated. The current basic pension in the short term to improve the life of the rural elderly has an important role, but the long-term need to continue to increase, should optimize the structure of fiscal expenditure.展开更多

Hicks-Henne shape functions are used to represent the bump shape. In the design optimization to increase lift-drag ratio, the objectives involve the cruise point and three other off-design points nearby. In the other optimization process to improve buffet and drag-rise performance, three buffet onset points near the cruise point and one drag-rise point are selected as the design points. Non-dominating sort genetic algorithm II （NSGA-II） is used in both processes. Additionally, individual analysis for every selected point on the Pareto frontier is conducted in order to avoid local convergence and achieve global optimum. Re- sults of optimization for aerodynamic efficiency show a decrease of 11 counts in drag at the cruise point. Drag at nearby off-design points are also reduced to some extent. Similar approaches are made to improve buffet and drag-rise characteristics, resulting in significant improvements in both ways.展开更多
