intracerebroventricular injection of urocortin ⅲ activates cell groups related with gustation, feeding and stress, the distribution of which partially overlaps with the sites of crf2r expression.

侧脑室给予urocortinⅲ激活了与味觉和摄食调控相关的细胞群以及与应激相关的细胞群，其分布与crf2r的分布大部分重叠。

Just 13, she was the ringleader of a group of hardscrabble kids who partied in the stairwells of parking garages in the dead of Winnipeg winter.

温尼伯市萧条的冬天里，一群穷困潦倒的孩子在停车库的楼梯井里玩耍。而年仅十三岁的她，正是这群孩子的头儿。

The structure of grade system and characteristics of the rural settlements group in Pinghu County are measured and analyzed with the Hausdorff dimension of settlements group, taking the township as a unit.

应用Hausdorff维数，以乡为单位，测算并分析了平湖县乡村聚落群的等级体系结构与组成特征；在乡级聚落群体系中，残遗聚落与发展聚落不属于无标度区

The results show that the two kinds of basic ant colony algorithm have better performance than classical K-means algorithm and hierarchal clustering algorithm, the two kinds of extended algorithm have better performance than corresponding basic ant colony algorithm.

实验结果表明，两种基本蚁群算法的聚类效果优于经典的K_means算法和层次聚类算法；两种改进的算法又分别优于相应的基本蚁群算法，达到了算法改进的目的。

It introduces the concept of power semigroup, studies the relations between homomorphism and congruence of power semigroup and obtains some perfect results.

给出了幂半群的概念，研究了幂半群的同态与同余关系，讨论了它们之间的关系，并得到了一些理想的结果。

Then the homomorphism s and isomorphisms of GV-semigroups were given by using the family maps.

定义一类映射，用此类映射描述GV-半群的结构，进一步认识GV-半群的结构。

This has something to do with its single evolution strate- gy because too single evolution strategy makes the swarm homoplasy.

这与粒子群采用单一的进化策略有关，因为过于单一的进化策略使粒子群整体上有一种趋同性。

We establish an asymptotic Lipschitz homotopy invariance theorem for these K-homology groups and K-theory groups. We show that the asymptotic index maps are isomorphisms for the asymptotically scaleable spaces, which include Euclidean cones, simply connected complete Riemannian manifolds with nonpositive curvature.

我们证明了这些K-同调群和K-理论群具有渐近Lipschitz同伦不变性；对于渐近可标度的几何空间（包括欧氏锥、单连通非正曲率完备黎曼流形等），证明了渐近指标映射为同构。
