In our thesis, contents are organized as following In Chapter 1 we present our topic's internal and overseas research situations, theoretical and practical significance, and introduce the research object and contents, and the main contributions of this dissertation. Chapter 2 reviews the development of the stability results for nonlinear systems and some relevant recent results, which include Lyapunov and LaSalle-Yoshizawa theorems for nonlinear systems, and stochastic edition for stochastic nonlinear systems. Sontag's formula for systems affine in control is presented in the frame of CLF. The concepts of disturbance attenuation and the inverse optimality are also explained in this Chapter. In chapter 3 we present the solvable theorem of inverse optimal gain assignment problem, design the inverse optimal controller and the inverse optimal tracking controller for strict-feedback nonlinear continuous systems with unknown time-varing bounded disturbances and constant unknown parameters using an adaptive backstepping algorithm, which are nonlinear, continuous and are easier to realize. These designs are fully systematic and the algorithm can be directly coded in symbolic software. The results of simulation show the effectiveness of the control algorithms.

It is the material base and environmental condition for social economy sustainable development to exploit and utilize farmland resources, and its crux is to carry out value compensation for the exploitation of the farmland on the base of ordonnance optimization and full utilization of the farmland in order to retain and improve productive quality and ecological function of the farmland, which makes the utilization of the farmland reach the best social, economic and ecological beneficial results.

农地资源可持续开发利用是社会经济可持续发展的物质基础和环境条件，其关键是在优化配置和充分利用农地资源的基础上，对农地资源的开发实施价值补偿，以保持和提高农地资源的生产性能和生态功能，使农地资源的利用达到最佳的社会、经济和生态效益。

At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。
