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。

It don't matter if you're black white, or yellow, if you're brown or red let's get down to that love is color blind you're my brother, you're my friend all that matters in the very end it's to understand love is color blind you could have been my mother you could have been my brother what if you are my sister if you are my father you could have been my feller you could have been my teacher but if you are my friend it would be so nice to meet ya you could have been my mother you could have been my brother what if you are my sister if you are my father i could have been your feller you could have been my teacher but if you are my

And we show that random walk model converges to the stable law of Lévy-Feller advection-dispersion equation by use of a properly scaled transition to vanish-ing space and time steps,We propose an explicit finite difference approximation for Lévy-Feller advection-dispersion equation.

第三章讨论描述服从某种稳定分布反常扩散的非对称空间分数阶对流-扩散方程——Lévy-Feller对流-扩散方程，首先利用Fourier变换和Laplace变换给出方程的基本解，然后利用Grünwald-Letnikov分数阶导数移位离散算子离散方程中的Riesz-Feller分数阶导数得到离散格式，证明此格式可以解释为离散随机游走模型，并且证明了当时间和空间步长以一定的比率同时趋于0时，所提出的离散随机游走模型收敛到Lévy-Feller对流-扩散过程的稳定分布。

Feller(1954) identified one of the new boundary conditions as the one describing this phenomenon and introduced finite sojourn time at the boundary for one dimensional diffusion processes and referred to such a process as "elementary return process".

为刻划这一现象，1954年Feller在边界上引入了有限的逗留时间并且把这类过程称为"基本的返回过程"。

Flexo business card printing and membership card making pressure adjustments is the crucial step of product quality, direct impact prints fine is good or bad, as printed on the roll and the spacing between the embossing roll is the same, you can choose to use 2.08mm (1.7 printing plate + 0.38 doubleside Strip) standard thickness of Feller gauge, so that both ends of the respective Feller gauge the same pulling resistance, at which point the amount of space is business card printing and membership card to make the best pressure value (but in actual production, you need to fine-tune your carefully at the operative level, it is necessary to the practical experience of technical personnel to obtain the best pressure value).

柔性版制卡和会员卡制作压力的调节，是产品质量的关键步骤，直接影响印品的精美好坏，印版辊与压印辊之间的间距是一样的，可选用2.08mm(1.7印版+0.38双面胶带)厚度的标准塞尺，使两端各自的塞尺拉动阻力相同，此时的间距就是制卡和会员卡制作最理想的压力值(但是在实际生产中，需要操作人员的仔细微调，那就需要技术人员的实际经验来获得最佳的压力值)。
