With high-speed development of modem science and technology ,global altitude for selecting managements mode in guidance of strategic management and continuously makes suitable adjustment accounting to the environments so as to coordinate and balance the enterprises against environment and acquire whole competition superiority of the enterprises.

随着现代科技的高速发展，全球性竞争加剧，企业不得不站在全球高度，选择以战略管理为导向的管理模式，不断根据环境做出适当调整，以谋求企业与环境的协调与均衡，从而获取整体竞争优势。战略管理对传统管理会计提出了挑战，迫切要求传统管理会计更新观念，尤其是对战略决策信息的提供，要求提供更为广泛、更有用的与战略管理相关的信息。

Providing also a self-contained presentation of classical isoperimetric inequalities for eigenvalues and 30 open problems, this book will be useful for pure and applied mathematicians, particularly those interested in partial differential equations, the calculus of variations, differential geometry, or spectral theory.

为eigenvalues和30个开放式问题也提供古典isoperimetric 不平等的拘谨的赠送，这本书将是对纯并且被使用数学家有用的，特别是对偏微分方程，变分法，不同几何学或者光谱的理论感兴趣的那些。

Through above study, the theoretical analysis of the inherent fault tolerance of feed-forward neural networks has been extended from hard-limit activation functions to differentiable activation functions; 2. By using above method, fault tolerance of discrete Hopfield feedback neural networks have been also analyzed. It means that the above method can be applied not only for feed-forward neural networks but also for feedback neural networks; 3. For the feed-forward neural network with the Sigmoid activation function, Chebyshev Inequality method was presented.

这项研究将以前仅限于对硬限幅作用函数前向神经网络固有容错性能的理论分析推广到具有可微作用函数的前向神经网络； 2 针对离散型Hopfield反馈神经网络，利用上面提出的方法，对其同样进行了容错性分析，得出许多有用的结论和计算公式，说明上面提出的方法不仅适用于前向神经网络，同时也适用于反馈神经网络； 3 针对具有Sigmoid作用函数的前向神经网络提出了一种切比雪夫不等式法。
