The graph vertex coloring problem is the main topic of graph theory and applied in many fields, which is known as NP-complete problem.

图顶点着色问题存在于丰富的科学和工程应用中，如工序问题、排课表问题、物资储存问题等等，但它却是众所周知的NP-完全问题。

From the conception of administration of intangible assets, including the definition, main characteristic , the importance of administration of intangible assets is clarified and introduce the theory of human resource and technological innovation about intangible assets, then, I put forward some question in the administration of intangible assets in our country. I explain questions on administration of intangible assets, which are exploiting and using .Attention is paid on exploiting technology and brand. As for using intangible assets, explanation are given to absorption of venture investment , hypothecated loan for financing by assets, absorption of foreign investment. At last, the method is given to assess the administration of intangible assets.

本文从无形资产经营的界定谈起，对无形资产经营的涵义、主要特征进行阐述，论述了无形资产经营的重要意义，并且介绍了无形资产经营相关理论；然后针对我国无形资产经营发展状况，提出我国无形资产经营方面存在的问题；接着，本文从无形资产开发和利用方面探讨了无形资产经营问题，其中对无形资产开发问题着重关注技术、品牌等无形资产的开发问题，在无形资产利用问题中探讨了多种运用无形资产的方式：利用无形资产吸引风险投资、利用无形资产进行融资担保、通过特许经营利用无形资产、利用无形资产吸引外商资金、转让无形资产所有权等；最后，本文针对无形资产的经营提出评价其经营结果的方法。

In the second part, we studied blind source separation in ill conditioned cases, obtained the sufficient and necessary conditions on solvability, and presented the neural network model and corresponding adaptive algorithm. We also discussed the blind digital source separation, established the blind separation and extration models and algorithms. These algorithms can be used to deal with high noise and ill-conditioned cases.

在第二部分，我们研究了奇异混合情形下信号盲分离问题，给出了神经网络模型及相应的自适应算法；我们也研究了数字信号盲分离问题，得到了有关可解性的充要条件，提出了分别处理低噪声问题和高噪声问题的算法，这些算法对感知信号个数少于源信号个数等病态问题也适用。

Think, the traditional economics research about human problem is more the ground is the premise that regards research as economic problem, new system economics revised the human hypothesis point of view in traditional economics afresh, undertook immediateness real research more to human problem, and as a result of,be in charge of criterion of a Confucian school of idealist philosophy of the Song and Ming Dynasties its core problem -- the management to the person, accordingly, its formed management to learn the serious content of research to the research itself of human problem.

认为，传统经济学有关人性新问题的探究更多地是作为探究经济新问题的前提，新制度经济学则重新修正了传统经济学中的人性假设观点，对人性新问题进行了更接近现实的探究，而管理学则由于其核心新问题——对人的管理，因此，其对人性新问题的探究本身就构成了管理学探究的重要内容。

But at present, the fields of enterprise and theory have not attached importance to the problem of enterprise product mix adjustment, which is mainly reflected in the following aspects. The first is that most enterprises maintain existing situation of product and enterprise and solve sale problem by the way of sales promotion while facing market problem. The second is that most enterprises follow others blindly while consider the problem of market entry, but is passive not active while facing market dropout. The third is that in the aspect of management most enterprises don"t make adaptive managerial strategy according to enterprise"s interior and exterior situation, but flow the routine "learn from successful enterprise, elude failing enterprise". The fourth is that the study on the enterprise product mix adjustment from the side of theory is scarce and fragmentary, immethodical.

但是，目前企业产品结构调整的问题还未引起企业界和理论界的重视，主要体现在：一是面对市场问题，大多数企业是维持现有的产品和企业状况，通过促销手段来解决产品销路问题；二是对待企业产品市场进入的问题上，大多数企业是盲目跟进；而对产品的市场退出，大多数企业往往是被动而非积极主动的；三是在经营方面，大多数企业基本上走的还是"学习成功企业，规避失败企业"的路子，没有从企业自身的内部条件出发，为企业量身制定适合的经营战略；四是迄今为止理论界对企业产品结构调整问题的研究还是少之又少，有关产品结构方面的研究还只是零星、不成体系的。

The layout scheme design of spacecraft vessel belongs to 3D packing problem with behavioral constraints, and it is also a complex engineering system problems with inscrutability, uncertainty, high nonlinearity, quality and quantity. It is almost impossible to solve it completely by human or computer alone.

航天器舱布局方案优化设计属带性能约束的三维布局优化问题，属具有不确定性、高度非线性、既有定性又有定量问题的复杂工程系统问题，单纯依靠人或计算机算法去解决都是非常困难的。1991年Lenat、Feigenbaum提出的人机合作(Man-Machine Synergy)和同年钱学森、戴汝为等提出的人机结合(Human-Machine Cooperation)思想和方法论，被认为是21世纪解决复杂工程问题的重要途径、自动化设计的重要发展方向，但其可操作性问题一直未很好解决。

New boundary integral equations for the torsion problem of an isotropic bar with curvilinear cracks are derived by using integration by parts and other techniques to the traditional boundary integral formulations. And the boundary integral equations for the torsion problem of an anisotropic bar with curvilinear cracks are also derived by using the isotropicalized boundary element method. Then the anisotropic problem can be solved on the base of the boundary element method of isotropic problem.

然后用各向同性化方法，将各向异性材料裂纹柱体的扭转问题转化为各向同性材料的问题，在各向同性材料裂纹柱体扭转问题的新的边界积分方程的基础上，推导出了适用于各向异性材料裂纹柱体扭转问题的边界积分方程，然后按已推导出的各向同性问题的边界元法求解。

If a company went a problem, we can say this is the problem that company interior administers, but if a lot of companies went a problem, then we can say this is the problem of the market only, the problem of the system.

如果一家公司出了问题，我们可以说这是公司内部治理的问题，但如果很多公司都出了问题，那我们只能说这是市场的问题，制度的问题。

Since the graph isomorphism problem is neither known to be NP-complete nor to be tractable, researchers have sought to gain insight into the problem by defining a new class GI, the set of problems with a polynomial-time Turing reduction to the graph isomorphism problem.

由于图同构的问题既不是已知的NP完全问题，也不是听话的，研究人员设法深入了解这个问题，确定了一类新基的一系列问题，多项式时间图灵减少的图同构问题。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
