约束

A new symbol-constrained joint source-channel decoding algorithm for VLCs is presented.By constructing double-tree VLCs sources,the propagation-error problem is evidently alleviated.Meanwhile,by applying symbol-constrained method to MAP algorithm,not only the a priori probability of VLCs sources is efficiently utilized,but also the Symbol Error Rate is reduced enormously.

提出了一种新的针对不等长编码信源的符号约束MAP联合译码算法，利用VLCs双树信源的构造方法，有效地抑制了VLCs的错误扩散；同时，通过将"符号约束"的思想应用于最大后验概率译码算法，不仅充分利用了信源先验信息，而且极大地降低了误符号率。

At the same time, we should also consummate the restricting mechanism by their self-locating to form them self-restricting. Then we should exercise the punishment rationally and found up the credit evaluating system to restrict their behavior so that finally we can satisfy the efficient demand of the insurance market and help the insurance company operate and develop steadily.

同时，应完善对个人保险代理人的约束机制，通过个人保险代理人的自我定位形成自我约束，再通过对合理的惩罚力度的运用和个人保险代理人信用评估体系的建立来约束个人保险代理人在展业中的行为，从而满足保险市场的有效需求和保险公司的稳定经营和发展。

The second section analyzes the restraint conditions of establishing zero-coupon bond yield curve in China. In order to analyze the constraint conditions of establishing zero-coupon bond yield curve, we should firstly study the current situation and problems of Chinese bond market because the data estimating zero-coupon bond yield curve mainly come from bond market which can't be separated from the analysis of the development history of bond market. So the main content of this section includes the development history of bond market, the present problems of Chinese bond market and the restraint conditions of establishing zero-coupon bond yield curve in China.

第二节分析中国零息票债券收益率曲线构造的约束条件，由于估计零息票债券收益率曲线所需要的数据主要来自债券市场，这样，要研究零息票债券收益率曲线构造的约束条件，首先必须研究中国债券市场的现状和问题，而这一切又离不开对中国债券市场发展历史的分析，因此本节的内容包括中国债券市场发展的历史沿革、中国债券市场目前存在的主要问题和中国零息票债券收益率曲线构造的约束条件三个部分。

The third section establishes zero-coupon bond yield curve based on restraint conditions. The contents refer to data collecting and data handling, model establishing under restraint conditions and empirical analysis.

In the second chapter, we discuss the depletion interaction between two big hard spheres under the symmetrical geometry confinement. The depletion interactions under the unsymmetrical geometry confinements are studied in the third chapter. The second and the third chapter involve the author s original works.

In this paper,we research into semantic constraints detection among text; expect to correctly detect the semantic constraint parts which are denoted by signal words and correctly disambiguate multi-semantic constraints when they are denoted by a same signal word.

本文对文本中语义约束信息的识别展开了研究，期望对有信号词指示的语义约束部分，给出正确的检测，并对由同一信号词指示的多种语义约束，给出正确的区分。

The new rT joint not only has two rotation axes that intersect at right angle,but also has another rotational degree of freedom which can be used to modify the assembly of other joints.This can change the mobility of the parallel mechanisms that assembled with the new rT joints and leads to two types of metamorphic paralllel mechanisms:In the first type,the mechanism changes its topology by turning the new rT joints in all limbs into different configurations which reconfigures the constraints within the limbs or the assembly of all the limb constraints.This change of mobility is completed by two cases.One is illustrated by a 3PS and a 3C parallel mechanism,by altering the rT joint into different configurations there will produce or reduce local degrees of freedom and thus change the constraits to the moving platform.This qualifies the 3PS and 3C to have variable mobility from 3 through to 6 and from 1 through to 6 respectively.

该铰链除了一般Hooke铰的两个轴线互相垂直相交的旋转自由度外，还增加了一个可以调节该两个轴线之一的姿态的一个旋转自由度，通过此自由度调节该rT铰到不同的装配构型，可以改变用其装配的并联机构的自由度，由此产生两类新型的并联变胞机构：一类是机构的各个支链中都有rT铰，该铰链的不同构型可以改变各支链对运动平台的约束或整个支链组的组合形式而改变机构的自由度状态，3PS和3C属于前者，通过调节rT铰到不同构型可以使其支链产生或消失局部自由度，从而减少或增加支链对运动平台的约束，使得并联变胞机构3PS和3C分别具有自由度从3变到6和从1变到6的能力；3P属于改变支链组组合形式的机构，其rT铰的不同构型将改变整个支链组的几何约束组合，使得并联变胞机构3P可以有三转动、三平动或三平移(来源：ABCded9de论文网www.abclunwen.com)一转动的自由度形式。

In this paper, taking the reliabilities of constraints into the modified constraint conditions, optimum design of object function was carried.

在优化设计的平台上，综合考虑每一约束的可靠性，产生通过可靠性设计后的改性约束条件，再在众多的改性约束条件的前提下，进行目标函数的优化设计。

The conclusion provides the theoretical basis for applying appropriate restraining pressure to preventing frost heave in engineering field.

并不需要约束压力大到接近或等于&中断压力&的程度，而可以通过加筋或选择适当的结构形式提供约束压力使冻胀的土体向融土区的方向压缩，利用融土的压缩量抵消部分冻胀量，即可在约束压力较小的条件下，使建筑物发生的冻胀位移大大减小。

So resolving this kind of problem efficiently has great research value in theory, and especially resolving those problems, such as resource allocation, job shop scheduling, timetabling, and routing, still has very important realism significance and commerce significance.

本文主要研究内容为基于约束的现代调度，即运用约束程序设计方法来求解现代调度问题，从而拓展了约束程序设计在求解组合优化问题方面的应用领域。
