约束

Henceforward, the capital、technology and the person with ability are not the main reasons any more to inhabit the development of economy,but the system environment.

今后约束经济发展发展的已经不完全是资金、技术、人才问题，约束今后经济发展的瓶颈，越来越体现为制度环境。

Accordingly, the two-way establishment of self-discipline and heteronomy is the fundamental avenue to the construction of civil morality in our country at present.

从道德实践的层面上说，道德作为调整人与人之间、人与社会、人与自然之间相互关系的行为规范，其实现的途径应将内省式自我约束和外在的社会约束方式结合起来，道德人格的培养也需要在自律与他律的矛盾运动过程中实现。

This dissertation proposes the definition of orientation workspace, which is fit for the hexapod machine tools cutting the surface.

对于关节几何约束下工作空间的分析发现，关节的几何约束对姿态空间影响显著。

Chapter 2 converts the solutions of saddle point problems in Hilbert spaces intothe equilibrium points of some dynamic system by means of the projection method,and gives some conditions of global asymptotic stability by extending the LaSalleinvariance principle to Hilbert spaces.

第三章把约束鞍点问题转化为等价的无约束问题，然后利用投影法构造了一个神经网络模型进行求解，并利用第二章结论证明了在适当条件下，模型大范围收敛于问题的精确解。

In IBR (image-based rendering) application, we introduce homotopy mapping into view interpolation based on uncalibrated images, and present three forms of perspective homotopic transform according to different conditions.①The linear interpolation technique presented only preserves perspective geometry, but the intrinsic and extrinsic parameters of camera are changed. For the uncalibrated images, its application is restricted.②The view interpolation presented for rotational uncalibrated images can preserve both perspective geometry and the intrinsic parameters of camera, and the view position can be controlled. At meanwhile, the image registration method and panoramic images synthetic method is presented.

3在基于图象的绘制技术方面，将同伦变换引入视图插补中，针对未标定图象序列，并根据以下三种情况给出相应的透视同伦变换，①只保证符合透视关系，而摄象机内外参数均已改变的线性插补技术，对于标定图象序列，这种插补技术是非约束的，而对于未标定图象序列则只适合于某些特殊场景；②旋转图象序列的视图插补技术，同时给出了旋转图象序列的整合及全景图生成方法；③通过对非约束图象的预校正，完成平移情况下的视点插补。

Arising from a natural inclination or impulse and not from external incitement or constraint.

无约束的，不须学习的在仪表或行为上无约束或无须学习的

In fact, any number of rows can include nulls for columns without NOT NULL constraints because nulls are not considered equal to anything.

由于空值与任何值比较都无意义，因此定义了 UNIQUE 键约束而没有定义 NOT NULL 约束的列上可以包含多行值为空的记录。

Optimal algorithm of combined nonlinear Hopfield network appears powerful validity in solving nonlinear planning, which includes nonlinear objective function, linear constrains and high-demension of decision-making variants, for its ability of nonlinear parallel computation. It is prominent among optimal algorithms because of its function of simply implement with electrocircuit hardware. Genetic algorithm is expressly suitable for optimal calculation regarding the planning of massive, highly nonlinear, inconsecutively differentiable and multiobjective function as well as objective function without analytical expression. However, it inclines to prematurity, as well as its limitation in ability of partial optimal search. Introducing the optimal algorithm of niche genetic simulated annealing to standard Genetic algorithm, can therefore improve the full-scale or partial search ability of Genetic algorithm effectively. It has a far-flung perspective in the field of systemic planning of water pollution control.

组合式非线性Hopfield网络优化算法所具有的非线性大规模并行计算能力在求解具有非线性目标函数、线性约束条件及高维决策变量的非线性规划问题方面显示出了强大的生命力，它易于电路硬件实现的功能更是在优化算法中独树一帜；遗传算法采用概率搜索技术，不受目标函数与约束条件的限制，特别适合大规模、高度非线性的不连续可微的多峰目标函数及无解析表达式的目标函数的规划问题的优化计算，但其存在容易早熟、局部寻优能力较差等缺点，本文在标准遗传算法中引入小生境技术及模拟退火算法有效地改善遗传算法的全局和局部搜索性能，提高了全局最优解的寻优质量，小生境遗传退火模拟优化算法在水污染控制系统规划中的应用前景极为广阔。

It lays greater emphasis on the control and the elevation of the individual, therefore it is possible that personal freedom will be in a state of constant repression. On the other hand, the hierarchical nature and the relative indeterminateness of the Ethical Code itself prevent the Code itself from developing into an effective instrument to restrict the power of the government in practice.

与之相反，在中国的思想传统中，"礼"并不具有一种类似西方的法律的中介作用，它更多强调的是对个人的约束与提升，所以也有可能使个人自由始终处于一种受到压抑的状态，另外，"礼"本身所具有的等级性和相对的不确定性也使它不可能在实践中成为约束政府权力的有效工具。

Finally, in order to enforce the given inequality constraint, a constraint transformation method for the marked graphs is proposed due to accounting for uncontrollable transitions in the net.

最后，本文还研究了在由标识图建模的DES的框架下，为了实现给定的不等式约束而必须考虑Petri网中不可控变迁的影响而进行的约束变换的方法。
