The conclusion is that the path of Nanjie's institutional change is the outcome of the coevolution, say, competition, constraints, enforcement and transformation between the state and market; the coevolution have three dimensions: benefit, legitimacy and ideology; the path and outcome of institutional change in the process of coevolution are shaped by both the dual process of modernization and marketization in China's social transformation and the path dependence and cultural lag in China's incremental reform strategy: on the one hand, as historical conditions, the proceeding and logic of China's modernization constraint the state and market's institutional choices; on the other hand, under the interplay between the path dependence and cultural lag, the interaction between the state and market can produce various complex combinations, therefore various institutional landscape, even "institutional paradox".

本文认为，高度政治化、高度集体化的南街村体制是国家与市场互动演化，即国家与市场之间相互竞争、制约、强化和改变的结果；国家与市场之间的互动演化有利益、合法性和意识形态等三个维度，而互动演化所造成的制度变迁轨迹和结果则同时受中国社会转型中的现代化进程和市场化进程，以及渐进式改革中的路径依赖和文化堕距的影响：一方面，现代化进程作为一种共同的历史条件制约着国家和市场各自在互动过程中的制度选择；另一方面，在路径依赖和文化堕距的交互作用下，国家与市场之间的互动会形成多种复杂的、犬牙交错的组合，从而塑造出千姿百态的制度景象甚至"悖论"。

In history and reality, the contradiction between needs and limited resource always exists. From the view point of system-science, it can be concluded that:①The interaction among need-contradiction-ability is the perpetual force for enterprise evolution (and the evolution of other living systems). The improvement of "ability"is the process and result of evolution.②The competition and coordination among systems is the direct power for enterprise evolution. Competition produces various system actions. Coordination makes systems complement their functions with each other. The interactions of competition and coordination push enterprise into the flow of evolution and optimization.③The"stochastic fluctuation"of the system, which is accidental finding, is another force for enterprise evolution. It is a deterministic element in the process of the self-organization of enterprise.

在历史和现实中，需要和满足需要资源稀缺之间的"问题"是恒久存在的，从系统科学的角度可以演绎出：①需要一问题一能力三种异质要素的相互作用是企业进化（其它一切有生命系统进化）的永恒动力，"能力"的提高正是进化的过程和结果；②各系统间的竞争与协同是企业进化的直接动力，竞争产生多样化的系统行为，协同则使各系统间优势互补，竞争与协同交互作用推动企业呈现出进化与优化的趋势：③系统的"随机涨落力"即意料之外的发现与创新是推动企业进化的又一种动力，它是企业自组织过程中带有必然性的力量：④在解决"问题"中创新者的作用不可低估，但更为根本地说创新者只是"需要一问题一能力"这三种要素相互作用的载体，个体的创新是企业自组织过程的必然结果。

In view of the demand of computerized eye-glasses-wearing system, an approach to match two dimensional (2D) human head images with 3D glasses frame graphics in 3D space has been proposed. First, the operator points out three or six key points, which are used to locate 3D eye-glasses frame, on the human face image displayed on the computer screen interactively.

论文针对计算机化眼镜配戴系统的要求，提出了一种在三维空间匹配二维人头图象和三维眼镜图形的方法，即通过人机交互方法，由操作者在显示于计算机屏幕上的二维人头图象上，指出确定三维眼镜位置的三个或六个关键点的二维坐标及其三维对应点，从而可以近似求出人面朝向及视点坐标，再用相应位置上的三维通用人头图形替换二维人面图象，计算人面和眼镜间的遮挡关系并显示，从而完成二者的空间匹配。
