Another is that retaining the refined Ritz vector in the new subspace,calledaugmented Krylov subspace.This way retains useful information and makes theresulting algorithm converge faster.

改进后的求解子空间为一增广Krylov子空间，该空间中包含更丰富的特征向量信息，因此用精化Arnoldi方法在该空间上求解矩阵特征问题时收敛速度更快。

In this paper, a path planning method based on GA is presented. Firstly, the model of the space robot is built to display the mapping of the end velocity and the joint velocity. Then the optimal algorithm based on genetic algorithm is presented to search the optimal solution which minimizes the disturbance of base attitude in the feasible solution space. Finally, an illustrative example is used to verify the feasibility of the algorithm.

基于GA研究机械臂运动对基座的姿态扰动问题，首先，建立空间机器人的运动学模型及空间机器人末端与关节速度之间的映射关系；接着，应用GA作为最优化算法，在空间机器人可行解空间中，寻找最优解得到最优路径，以达到对基座姿态干扰最小的目的；最后，通过数值仿真实验验证算法的实用性。

Based on the analysis of influencing factors of agriculture development, Newton's theory of space as a guide, and Venn diagram as the display means, Beijing's agricultural development space was explored.

以农业发展空间影响因素分析为基础，借鉴牛顿的空间学说对农业空间进行划分，并以图示法为手段，直观地反映了不同空间的联系。

Virtual Space Teleconferencing System is based on video teleconferencing system. Participants appear in computer-generated virtual space as avatars, and these avatars can locate, view, manipulate virtual objects, communicate with others "face to face" in this space.

虚拟空间会议系统是在视频会议的基础上发展起来的，与会者以替身的形式出现在计算机生成的虚拟会议空间中，通过替身在虚拟空间中定位、观察、操纵虚拟空间的物体，与其他用户进行"面对面"交流。

ABSTRACT The key problems of researching and implementing a virtual space teleconferencing system are based on constructing a real-like virtual conference space , synthesizing all users in the common VCS according to their acture positions and orients, realizing nature interaction and collaboration among users.

如何构造具有真实感、空间感的虚拟会议空间，将所有的与会者按照正确的空间关系合成到这样一个共同的虚拟会议空间中，实现与会者之间自然方式的交互与协作，是虚拟空间会议系统研究与实现的关键问题。

We know that the c_0 spaces and l_1 spaces are not reflexive spaces, whether the ajoint semigroups on them are strongly continuous semigroups?

序列空间c_0空间、l_1空间都不是自反空间，那么定义在其上的强连续半群的对偶半群是否为强连续半群呢？

"XXXX" is allegorically providing a free shopping space and comfortable dress and also giving a infinite development zone to those "Freezoner" who is actively pursuing freedom.

&自由空间&的寓意是为顾客提供自由自在的购物空间，自然舒适的服饰。同时愿意为积极向上追求自由的自由空间人，提供一个自由无限广阔的发展的空间。

The results showed that the semivariogram of S.granarium was described by a spherical model,and indicated an aggregated special pattern ranging from 21 to 61cm. The semivariogram of Aphidius sp.could be also well described by spherical model, and indicated an aggregated spatial pattern ranging from 36 to 55cm.The amount and spatial distribution of Aphidius sp. w...

结果表明，不同时期麦二叉蚜种群的半变异函数曲线皆为球型，其空间格局为聚集型，变程在 2 1～6 1cm之间；蚜茧蜂种群的拟合半变异函数曲线也表现为球型，呈聚集空间格局，空间变程在 36～ 5 5cm之间，并与麦二叉蚜种群在数量和空间上有较强的追随关系，说明蚜茧蜂种群是麦二叉蚜种群的优势种天敌。
