We think that the main contributions of the book is in two aspects : one is the revolution of some concepts such as utility theory , aximatization of game , extended game ; the other is the breaking through in zero - sum two - person games centered on minimax and corporation game centered on characteristic function . this was , in fact , the development and extension of von neumann ' s classic game paper of 1928 . our research shows that these contributions were a pure new theoretical creation , rather than an 认为《博弈论与经济行为》的主要贡献有二个方面：一个方面是在效用理论、博弈的公理化、博弈的扩展形式等等概念上的创新，另一方面是在以极小极大值定理为中心的三人零和博弈理论和以特征函数为中心的合作博弈理论上的创新，这些实际上主要是冯?诺伊曼对其1928年的经典博弈论文章的理论框架的发展和延伸
With the analysis of this model , this paper point out that the distribution of ownership and the control right are according with what we learned form the modern enterprise theory in which the residual claim right be required to match with the residual control right in nature , but there is difference between them in the form to the venture enterprise coming from the character of venture investment 通过对模型及其扩展形式的分析得出，在风险企业中的控制权与所有权的分配在本质上与现代企业理论中所强调的“剩余控制权与剩余索取权相匹配”是一致的，但是因为风险投资的特点而在形式上有所不同。
Based on the saint - venant equations describing the channel flow movement , the nonlinear algebraic equations derived by the use of preissmann weighted implicit four - point scheme are solved with the netwon - raphson method , which raises the accurate of the numerical solution , and the convergence of the numerical solution is discussed , 2 用newton方法直接求解按preissmann加权四点格式离散扩展形式的saint - venant方程组所得的非线性代数方程组，提高了数值解的精确性，并对数值解的收敛性进行了讨论。
Aiming at the function and performance limitations of traditional special cnc or current pc - based open - structure cnc , a brand - new cnc platform designing scheme of multi - layer open - architecture is presented , based on embedded - mcu calculation and management core , and three kinds of expanding mode of software , hardware and interface . by using double system working ram and boot rom technology , an independent re - development interface is set on the hardware platform to realize customized function ’ s simulations and verifications online , which makes all the expanding or re - configuring on basic cnc platform are all safe and restorable 本文针对传统专用数控系统的结构封闭、交互形式不通用和配置扩展不灵活方面的劣势以及当前pc模式开放结构数控的体积庞大、开放程度不高和实时可靠性不强的局限，创新性地提出了以基本cnc框架+软件、硬件和接口三种扩展形式为特征的层次化开放结构的嵌入式cnc硬件平台，并采用双存储区技术进行了cnc系统在线仿真校验机制和安全保护机制的方案设计。
