可构造的

Based on two algebra Riccati equation method especially the structure of the system Hamilton matrix and system observability theory, the role of invariant zeros in constructing system reduced order controllers was given. That is, by the suitable selection of free parameters of the system H(subscript ∞) controller, some points which were symmetry with the unstable invariant zeros about the imaginary axis became the stable poles of the system controller which were not observable and could be reduced from the system, thus could get further reduced order controller.

基于2代数黎卡提方程方法，特别是系统Hamilton矩阵的结构特点和系统可观测性理论，论述了不变零点在构造系统降阶控制器中所起的作用，即通过选择控制器的自由参量，使某些不稳定的不变零点关于虚轴对称的点构成系统控制器不可观的稳定极点，从而实现了控制器进一步降阶。

In chapter 3 constructs firstlya new differential merit function by a perturbation structure of VIP and study theproperties of this merit function.Based on this merit function,a continuation-typeNewton method is proposed,which use the technique of inexact linear search forassuring its global convergence,and improves essentially the method of Taji,Fukushima and Ibaraki which can only solve the strong monotone VIP,and has locallyquadratic convergent rate under some condition.

第三章利用变分不等式问题的一种扰动结构构造了新的可微效用函数，并研究了效用函数的性质；在此基础上，给出了一类求解一般单调变分不等式问题的连续型Newton方法CN，方法采用了不精确的线性搜索技术以确保整体收敛性，从本质上改进了Taji、Fukushima和Ibaraki方法只能求解强单调变分不等式问题的局限性，同时又保持了局部二次收敛率。

We construct a kind of special matrix function, which is used to characterize the minimization property of this iterative method, and prove that the approximate solution, generated by this iterative method, minimizes this kind of matrix function over a special affine subspace, which means that the Frobenius norm of the residual sequence is strictly monotone decreasing.

通过构造一类特殊的矩阵函数来刻画该迭代方法的极小化性质，并证明了由该迭代方法计算出来的逼近解，可使得这类矩阵函数在一个仿射子空间上达到极小，而且所得到的残差序列的Frobenius范数是严格单调递减的。

这其中的一个新颖思想就是，在植物的染色体内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。

One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants' natural constitution; specifically, the idea of inserting into nonleguminous plants the genes, if they can be identified and isolated, that fit the leguminous plants to be hosts for nitrogen-fixing bacteria.

Based on the dating of Late Cenozoic strata and lithology changes analyses, it can infer the ages of layer landforms formation and the time of broken planation surface.

通过对晚新生代沉积地层高分辨率的环境磁学研究可进一步捕捉重大的环境变化事件，测定其形成的年代及变化，并推测剥蚀面形成和抬升的时间以及确定这些层状地貌形成的时代，进而推演六盘山和青藏高原构造隆升的历史。

That might explain why Luo is enchanted by specimen. He staged a scene of a museum that displays the pieces of his memories and mental pictures through the laying out and reconstituting the cross-sections of rocks. The procedures only exist in a momentary flash on the canvas. Though there are similarities between Luo's themes and those of Japanese photographer Sugimoto Hiroshi, Luo's objects are at greater ease than Hiroshi's. This is the reflection of Luo's sentiment, an attitude of self-complacent that elder Chinese literati had.

这也就不难解释罗荃木对于标本的偏好，并将场景直接地自博物陈列中撷取，这拼凑自艺术家记忆或相片的过程正如将摊平剖析过后再度构造出的山石，成为了只存在于画布中某个过去的瞬间；但有趣的是，这些标本都存在着一种自在，这份感觉是无法在杉本博司摄影中看到－这是艺术家自己对于外在世界情感的写照，超然幽淡的生活状态，并可呼应宋时以写生观察自然、寄情自然的文人思维。

Study on Applying CSG Method to 3D Model of Buildings;2. Research of 3D Model on Road Engineering Geology;3. A new kind of stair-climbing vehicle construction based on the structure principle of telemotor vehicle and design feature of micro mobile vehicle for scout as a preliminary research achievement is designed, and its 3D model is created with MDT software.

在预研完成的微小型移动侦察车的基础上，受遥控电动小车构造原理的启发，设计了一种可爬越楼梯的新型的车辆结构，并采用三维机械设计软件MDT完成了三维建模，同时还简要地分析了该车爬越楼梯的力学原理，在一定程度上促进了微小型地面移动机器人技术的研究开发工作。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
