约束

According to certain tie in 2 values image the condition finds candidate face and demarcate, search the area of " empty " in 2 values image next, if position of " empty " shows acute angle triangle to distributing fitly, and be located in inside candidate face area, prove this awaits electorate region to be person face area namely.

在二值图像中依据一定的约束条件找到候选人脸并标定，然后搜寻二值图像中的"空洞"区域，假如"空洞"位置恰好呈倒锐角三角形分布，且位于候选人脸区域内，则证实此候选区域即为人脸区域。

The temporal constraint network is a kind of directed acyclic graph,and could well represent temporal logics.

在人工智能研究领域发展起来的时序约束网络是一种能够清晰而直观地表示时序逻辑的有向无环图，适于解决计及警报信息时序特性的警报处理问题。

Core saturation and the rotor bar skin effects were directly taken into account in the field calculation. The adopted circuit equations are suitable for describing the stator windings and the special rotor-bar connections of BDFM. The waveform of supplied voltage source may be an arbitrary. Three-dimensional end effects were considered in the circuit parameter corrected by classical formulas. In addition, the coupling and constraint equations were used to handle rotor rotation without any process of remeshing.

其特点是：铁心饱和以及转子导条集肤效应可以直接在场的计算过程中加以考虑；采用的电路方程可以方便地处理无刷双馈电机定子绕组和转子端环的各种特殊连接方式，电压源可以是任意电压波型；三维端部效应可以通过传统的方法在电路参数中加以修正；采用耦合与约束方程来处理转子转动问题，而无须不断地对转子重新进行刨分。

To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。

Use the Colinear Constraint tool once again to make the bottom line of the rectangle colinear with the bottom edge of the adjacent face.

再次使用「共线约束」工具，以确定矩形的底线与邻接面的底边共线。

Author takes a crank-leader mechanism as the instance, demonstrates general method of adjustability mechanism design.

对具有一个中间自调齿轮的齿轮机构无过约束设计方案，深入的进行了其自调机理的分析。

The admissibility of functions is regulated by continuity requirements and boundary conditions.

函数的容许性由连续性要求和边界条件来约束。

In the last chapter,we study the control problems of the distributedparameter system governed by a class of higher order pseudohyperbolicequation related to the symmetric regularized long wave equation.we havediscussed the controllability and optimal control problems.we have obtainedcompatibility condition of the constraint when the state is controllable,therepresentation of the optimal control for both the time optimal control problemand the optimal control problem of minimum energy type,and the equationsatisfied by the minimum time.we have shown that the optimal control belongsto the boundary of the admissible control set.

在第六章中，我们研究了与对称正则长波方程相关的一类高阶拟双曲型方程支配的分布参数系统的控制问题。讨论了系统的状态能控性问题和最优控制问题，给出了状态能控时的约束相容性条件，给出了最速控制问题、最小能量型最优控制问题的最优控制表达式和最速时间所满足的方程式，证明了最优控制属于控制集合的边界。

In the thesis , firstly the problem of static output feedback H∞control was explored for discrete time singular systems. Based on the generalized Riccati inequality and linear matrix inequality, necessary and sufficient conditions were obtained for the existence of static output feedback H∞controllers, which guarantees that the resulting closed-loop system is admissible with its transfer function matrix satisfying H∞norm constraint.

本文首先利用线性矩阵不等式和广义Riccati不等式，给出离散广义系统中存在静态输出反馈H∞控制器，使得闭环系统是容许的且其传递函数矩阵满足H∞范数约束的充要条件。

When the relative velocity between missile and target is high, the change of the LOS will not be kept zero but vibrate. It can result in the system unsteady. A new SMG is designed. It do not request keeping the change of the LOS be zero all the time, but relax restriction advisably and automatically as missile approach target.

针对这一问题，设计了一种新型滑模制导律，其并不要求时时将视线角率控制为零，而是随着弹目标距离的减小，自动适当地放宽对视线角率的约束，从而有效缓解了传统滑模制导带来的强振荡问题。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
