Secondly, in section II of this chapter, we introduce the inequalities of Hermitian matrix trace with constrained condition and its application in statistics.

重要内容，它在许多方面都有广泛的应用。

Conventional forest breeding is constrained by its long reproductive cycle, which includes long juvenile period, and by its complex reproductive characteristics, such as self-incompatibility and a high degree of heterozygosis. Gene transformation has played an important role in woody plant improvement, which can shorten breeding period and breed varieties with high salt tolerance.

随着分子生物学技术的发展，从盐生植物中分离出抗盐基因，导入林木，获得抗盐品种；况且林木由于其较长的幼年期，常规育种有明显的局限性，而通过转基因可以在较短时间内获得高抗盐品种，缩短育种周期，因此开展林木抗盐育种具有重要的意义。

He believed that wealth and possessions constrained humanit 癫痫 ys natural state of freedom.

他以为财富、财产束缚了人们天生的自由状态。

Since an elementary reflection in the form of a Householder matrix can reduce any orthogonal matrix to this constrained form, a series of such reflections can bring any orthogonal matrix to the identity; thus an orthogonal group is a

因为 Householder 正交矩阵形式的基本反射可把任何正交矩阵简约成这种约束形式，一系列的这种反射可以把任何正交矩阵变回单位矩阵；因此正交群是

At present, the main method to ill-conditioned problem is normalization, namely constrained conditions are added to it.

目前解决病态的主要方法是正则化方法，即增加约束条件。

It is predicted by the Aspect Hypothesis that the perfective and imperfective aspect marking in native language and learner's interlanguage is constrained by the lexical aspect of the verb.

第二语言时体系统的习得是二语习得研究的一个核心领域。动词的情状体是影响二语时体习得的重要因素之一。情状体假设一方面揭示了语言中的一个普遍语法现象，即体范畴中的情状体特征；而且发现了这一语法现象对语言习得的作用。

The constrained low-cost restricts the improvement of government performance, other cost and implicit cost increases idle cost, the development of government transformation and civil society organization is slow, and constitutional problems still exist. These factors are the primary reasons which lead to low performance of the government administrative cost control in underdeveloped areas.

低成本制约了政府绩效的提升，制度外成本和隐性成本增加了无效成本，政府转型和公民社会组织发展缓慢，制度性问题等依然存在等，是导致落后地区地方政府行政成本支出绩效低下的主要成因。

Then this thesis presents another SLAM algorithm-the Relative Map Filter, The RMF is however disadvantaged by the inability to guarantee consistency of the estimated relative map. The following sections introduce a new navigation filter - the Geometric Projection Filter or GPF. The consistency of the estimated relative map is enforced by the application of the constrained estimator to an inconsistent relative map produced by a standard RMF.

然后介绍了SLAM问题的结构，分析了绝对地图滤波器的性质，介绍另一种解决方法—相对地图滤波器，但是相对地图滤波器产生不一致的相对地图，因此在相对地图滤波器的基础上应用约束估计产生一致的相对地图，这就是几何投影滤波器，从而有效的解决了SLAM问题。

But,I have a indistinctly artificial feeling always,it makes me constrained,so I cannot free my taciturn,my melancholy,my lonely and a little bit of cheerfulness.

可是总有一种隐隐的不自然感，使我无法肆意，挥洒我的沉默，我的抑郁，我的孤独和一些小小的快乐。
