This dissertation interprets Marx"s thought of leisure in terms of value philosophy, which is based on Marx"s stipulating value intension of leisure: First, leisure is a kind of living pattern as well as a value ideal, it is a value goal pursuing dynamic development that is realized constantly during the practical experience of life of people; Second, leisure is not only a question of free-time, but also persons value orientation.

本文选择从价值哲学的角度来解读马克思的休闲思想，正是基于马克思对休闲的价值内涵的规定：第一，休闲既是一种生活方式，又是一种价值理想，是人们在生活实践中不断追求实现的动态发展的价值目标；第二，休闲不仅仅是自由时间的问题，而且是个人的价值取向问题。

Different point basically is reflected in:(1) is on philosophical foundation, former it is guidance with Marxism philosophy, latter is directive;(2) to be on the purpose of research and jumping-off place with subjective idealism and metaphysics, former it is to be surplus value theory to lay a foundation, supply thought weapon for proletarian revolution, latter is to be bourgeois to serve;(3) to be on value source, former position works alive is the only fountainhead of value, latter thinks effectiveness or the fountainhead;(4) that effectiveness rate is value finally are on value Standard Dimension however, former consider as socially necessary labor time, latter considers as limit effectiveness to wait a moment.

不同之处主要体现在：(1)在哲学基础上，前者以马克思主义哲学为指导，后者以主观唯心主义和形而上学为指导；(2)在研究的目的和出发点上，前者是为剩余价值理论奠定基础，为无产阶级革命提供思想武器，后者则是为资产阶级服务；(3)在价值源泉上，前者主张活劳动是价值的惟一源泉，后者却认为效用或最后效用程度是价值的源泉；(4)在价值度量标准上，前者认为是社会必要劳动时间，后者认为是边际效用等等。

The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution.

基本思想是把连续的定解区域用有限个离散点构成的网格来代替，这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似，积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组，解此方程组就可以得到原问题在离散点上的近似解。

为了将这种耦合方法应用于二维外部定常的Oseen问题，我们人为的引入一条光滑的边界，将内部非均匀区域和外部均匀区域分离，外部区域的解可以由人工边界上的积分方程来描述，此积分方程同内部区域的速度-压力变分形式结合为耦合变分形式，我们则可以使用有限元的方法求解此耦合变分方程。
