对无噪音数据，平坦模型和光滑模型约束对反演的含水量分布影响不大；但当数据存在一定的噪音时，平坦模型约束将比光滑模型约束获得更为精确的含水层参数。

The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.

Quasi-convex relaxation algorithm, which aims to solve ordinary constraint global optimization problems, is produced by a combination of branch-and-bound method with quasi-convex lower bound and quasi-concave upper bound functions developed from quasi convex-concave extension. This algorithm extends the interval algorithm with box constraint to general constraint global optimization problem.

利用拟凸-凹扩张中构造出的函数的拟凸下界函数和拟凹上界函数，与分枝定界方法相结合，建立了求一般约束全局优化问题的拟凸松弛算法，这一算法是将盒子约束的区间算法推广到一般约束优化问题中。

Alternate namings for these restricted forms of cardinality were discussed.

OWL Lite 包括基数约束﹐它也称作局部约束﹐因为它们是宣告在某些特定类别的属性上面﹐也就是说这个约束限制了该类别实体的属性基数。

As a result, this seriously obstructs economic development step of our country. Therefore, starting from system and no-system, the paper sets up incentive and constraint mechanism according to the combination of material incentive and spirit incentive, long-term benefits and short-term benefits, system together with organize constraint and constraint by himself/herself, in order to solve the problem of agency and individual objective of manager deviating enterprise objective.

因此本文从制度和非制度建设出发，按照物质激励与精神激励相结合，长期利益和短期利益相结合，制度和组织约束与自我约束相结合，构建了对经营者的激励与约束机制，以期解决企业中存在的代理人问题和经营者的个人目标与企业目标相脱离的问题。

The sightline control strategy for bad measure precision is developed, and the control methods for vertical direction, approach direction and station keeping are presented.(2)The safe approach velocities are investigated for cuboid, sphere and cone keep out zone.(3)The design method for optimal trajectory under safety constraint is developed. The cone and cuboid keep out zone can be described using line constraint, and then optimal trajectory design can be translated to line programming problem under line constraint.(4) The design strategy of collision avoidance maneuver is discussed, and the collision avoidance scheme is analyzed for V-bar and R-bar approach.The control and trajectory safety in departure phase are investigated.

The rotor and its bearing, linked with small clearance restrict, makes up of the whole rotating system of unit power in ball pen production machine; its breakage and failure, first appear in the form of the failure of small clearance restrict, is caused directly by the unit vibration. Therefore, how to ensure good dynamic characteristics of rotating system is the thing worthy of note.

在多工位制笔机械的小动力头旋转系统中，转子与其支承之间是依赖小间隙约束而构成完整系统的，机组失效也总是最先表现在这类小间隙约束的破坏与失效上，而机组振动则是导致小间隙约束破坏的直接原因。

This algorithm is bases on that the number of period constraints of a circuit is great larger than that of non-negativity constraints on pracitical circuits. At first, we classify the pathes, and then compute the bounding of the retiming value.

接着根据实际电路中周期约束远远大于权重约束的情况，提出一种减少周期约束的算法，算法首先将路径分类，由不同路径来确定重定时值的取值区间。

Based on these plans, new plans were designed through replacing the physical constraints with maximum EUD for parotids, while keeping the physical objectives for targets and other organs at risk unchanged.

以这些计划为基础，将腮腺的物理约束条件改为EUD约束，而保持其他危及器官和靶区的约束条件不变，为每位患者设计一个新的计划，并比较新旧治疗计划。

Based on the above-mentioned characters, this paper analyzes and improves the building method of non-restraint triangulated irregular network and the embedded approach of constraint conditions, provides a kind of computational method which is used to compute the strip mine earthwork calculation based on constrained triangulated irregular network. a experiment system, which auto-complete the update of the strip mine relief map and earthwork calculation with the discrete elevation point, is developed by using the VBA development tool of AutoCAD.
