Earlier Wednesday, Thailand put fighter jets on alert at air force bases nationwide and C-130 transport planes on standby at a base in the capital, Bangkok , that could evacuate Thais living in the border area "if the tension escalates to a military confrontation," Thai air force official Group Capt. Montol Satchukorn said.

据泰国空军机群一名叫 Montol Satchukorn 的上校军官声称，本周三早些时候泰国曾经命令其在全国性空军基地的喷气式战斗机做好戒备并部署 C-130运输机停在其首都曼谷的空军基地，以便于"在紧张局势升级并爆发冲突时"能撤出生活在上述有争议边界地区的泰国人。

In this paper, we have made a systemic theoretic research on modelling and reshaping several types of spline curves/surfaces in CAGD. And some creative productions are given as follows. At first, the uniform C-B-spline basis is proved to be a normalized totally positive basis, and can be extended to a normalized B-basis. C-B-spline and C-Bézier basis, similar to B-spline basis and Bézier basis in algebraic space, are two bases in algebraic trigonometric space.

本文围绕着CAGD中常用的几种曲线曲面造型和形状调整进行了深入的研究，主要获得了以下一些成果：首先，证明了代数三角空间中的n次均匀C-B-spline基是一组标准全正基，并进一步扩充为一组标准B基。C-B-spline基与C-Bézier基是多项式与三角混合空间中的两组基，是适应工程实践中设计特殊曲线曲面的需要而产生的，类似于多项式空间中的B-spline基与Bézier基，是CAGD中重要的造型工具。

In order to solvepiecewise algebraic varieties, we propose a new method to compute an algebraic varietyon a convex polyhedron by adding hyperplanes with the method of Groebner bases. Thus,the algebraic variety on the convex polyhedron is transformed to the positive solutionsof a system of polynomials. Besides, the minimal decomposition is also obtained.

通过添加超平面技巧将Groebner基方法应用到凸多面体内任意维代数簇的计算上，从而把凸多面体内的代数簇转化为另外一组多项式方程组的正解，并且得到了该代数簇在凸多面体内的极小分解。

This paper proposes an algorithm of division and multi-level clustering with multi-strategy optimization,which bases on study of today's mature algorithms.

本文在研究已有成熟算法的基础上，提出了基于分治多层聚类的话题发现算法，其核心思想是把全部数据分割成具有一定相关性的分组，对各个分组分别进行聚类，得到各个分组内部的话题，然后对所有的微类再进行聚类，得到最终的话题，在聚类的过程中采用多种策略进行优化，以保证聚类的效果。

Now he wanted to bomb bases in Manchuria, a part of China, and use other all-out measures.

现在他给炸弹想要在Manchuria，一个中国的部分内的基础，和使用其它全面的措施。
