Secondly, three kinds of mathematics model of optical vortex beams were introduced here. Then the propagation dynamics of optical vortex beams through the non-axis symmetry system is studied, this chapter includes the introduction of the symmetry vortex beam and the non- symmetry vortex beam, the deduction of the Collins diffract integral formula for the non-axis symmetry system, and the transformation of the vortex beam passing through the non-axis symmetry system has been described by using the numerical simulation. Then the general calculation for the orbit momentum of vortex beams, the matrix form for the orbit momentum of vortex beams, and the photon method to describe the orbit momentum of vortex beams are also introduced here. Finally, the interference about optical vortex beams was studied.

本文对涡旋光束进行了较为全面的介绍和研究，主要内容包括：（1）光学涡旋光束的基本理论，主要是介绍了单个光学涡旋光束在柱坐标中的一些表征，涡旋光束的奇异相位和光学涡旋的相位结构；（2）光学涡旋光束的三种数学模型；（3）光学涡旋光束在非轴对称光学系统中的传播动力学，其中介绍了对称涡旋光束与非对称涡旋光束，推导了非轴对称光学系统的 Collins 衍射积分公式，并利用计算机模拟图描述了对称涡旋光束经过非轴对称光学系统后涡旋形态的改变；（4）涡旋光束轨道角动量的一般计算，涡旋光束轨道角动量的矩阵形式，光子法描述涡旋的轨道角动量；（5）涡旋光束的干涉。

It is indicated that this loss will not change with the increase of the Reynolds number but the intensity of the passage vortex increases with the decrease of the Reynolds number. The tip leakage flow will weaken with the increase of the passage vortex because of the interaction between the passage vortex and the tip leakage vortex, and the position of the tip leakage vortex is more close to the middle of the passage. In addition, the distributions of the total pressure loss and the flow angle at the exit of the cascade are influenced by the intensity and the position of the tip leakage vortex.

结果表明：对于间隙存在造成的流动损失，数值模拟结果与实验结果及 Denton的预测值都十分接近，基本上不随着雷诺数的变化而变化；但是，随着雷诺数的减小，通道涡增强；间隙泄漏涡在和通道涡的相互作用中，强度减弱，在叶栅出口处的位置更加靠近中叶展；出口处的总压损失和气流角的分布也由于间隙泄漏涡强度和位置的变化而发生改变。

The structure of this article is as follows: Firstly, the background of this article is stated in exordia and the question was raised; chapter one stated cash flow management theory and transnational corporations' cash flow management characters; chapter two introduced general cash flow management technical and method; chapter three analysis cash flow management situation of Chinese transnational corporations; chapter four take VW as an example to expatiate company situation and the impact to cash flow management by the organization of the company, the goal of cash flow management and financing strategy, then introduce the cash flow forecast module, at last analysis the experience and disadvantage of VW's cash flow management; Chapter five give some suggestions to Chinese local transnational corporations for cash flow management including: using proper cash flow management technical and establish scientific process, ect.; the last part is the conclusion This article took VW's cash flow management as an example to descried transnational corporation cash flow management theory and practical issues, but some techniques can only be used in some country where can exchange currency freely; it can not be practical in some foreign exchange administration countries including China, such kind of cash flow module still under discussion based on theory.
