Results show that the convergence is improved evidently.(3). The hybrid model which combines three-dimensional simulation in turbine and zero-dimensional simulation in the other engine components is built in the present paper after learning the zooming technique from NASA. The matching between components in a single-shaft turbojet engine after the turbine retrofitting is studied.

在对以上三种不同层次的数学模型及其解法进行了研究的基础上，鉴于NASA的部件一维仿真与总体零维仿真相结合的ZOOMING技术，本文采用将涡轮的全三维仿真与发动机总体的零维仿真相结合的方案，对某单轴涡喷发动机在涡轮改型后的匹配问题进行了研究。

Firstly, based on the sliding mode control and backstepping technique, a new attitude tracking controller is derived to control the attitude motion of spacecraft, the stability of the system is analyzed via Lyapunov method and the reaction wheel dynamics is also considered from the real applications point of view. The whole design process is divided into two steps: the first step is to use sliding control technique to design suppositional adaptive variable structure controller; and the second step is to design attitude tracking controller based on SMC and backstepping technique. Numerical simulations are performed to show that both tracking maneuver and vibration suppression can be accomplished effectively.

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.
