Chapter 1 gives the background,current research process of relatedproblems and summarizes this thesis\'s work.In chapter 2,we study the Brownian motion with holding and jumping on the boundary.We use the resolvent method to obtain the infinitesimal generator because the domain of the infinitesimal generator is essentially the same as the range of the resolvent.Knowledge of this range and of the differential operator determines uniquely the infinitesimal generator.Since the semigroup generated by the DHJ is not strongly continuous,to use the nice property of strongly continuous semigroup in analytic theory,in chapter 3 we show that the dual is strongly continuous and derive ergodicity through spectral radius formulas and finally obtain the ergodic theorem by duality. In chapter 4,we discuss a class of a more general process---one dimensional Feller diffusion proposed by W.Feller in 1954.The Feller diffusion allows the possibility of jumps from boundary to boundary,not only from boundary to the interior.We give the stationary distribution of this process.
具体地,本文的结构如下:第一章给出了问题产生的背景,研究现状及本文的主要工作;第二章研究了在边界上逗留后随机跳的布朗运动,我(来源:3dABC论文网www.abclunwen.com)们用预解算子的方法得到其无穷小生成元,因为无穷小生成元的定义域本质上就是预解算子的值域,知道这个值域和微分算子形式就能唯一地决定无穷小生成元;由于DHJ过程产生的半群不是强连续的,为利用强连续半群的一些漂亮性质,在第三章中我们证明其对偶半群是强连续的,然后由谱半径公式得到遍历性并且最后由对偶得到遍历定理;第四章讨论了Feller在1954年引入的更广的一类过程----一维Feller扩散过程,Feller扩散过程允许有从边界到边界的跳发生,即不仅仅局限于从边界到内部的跳,在这一章中,我们给出了一维Feller扩散过程的平稳分布;在第五章,我们讨论了一些相关的问题,给出了DHJ过程对应的PDE问题及特征值与收敛速度的关系。

论文以解决陕北地区的收入问题,植被问题以及粮食产量问题为出发点,首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性,然后结合陕北地区目前的实际情况,综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标:水利水保设施投入,农作物投入,经济林种支出,防护林支出,其它经济作物,草类支出,畜牧业投入;以退耕还林所要解决的最终问题作为输出指标:GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后,通过分析求解得出非有效的决策单元,再运用包络分析方法的一些基本原理对非有效的决策单元进行调整,由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时,又针对陕北地区在退耕还林过程中以及之后可能面临的困境,提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善,使农民尽快脱贫致富,使人口、资源、环境的关系尽快纳入良性循环的轨道上。
