下界的

In this thesis,we mainly study complete noncompact Riemannian manifolds with Ricci curvature bounded from below. We study the topology of these manifolds via comparisonal geometry methods.In chapter 1 ,we will make a general description on the recent researches in our field.

在本文中，我们主要研究了Ricci曲率有下界完备非紧的Riemann流形的拓扑问题，在比较几何的基础上研究了有特定曲率条件的Riemann流形的拓扑，得到了有关其拓扑结构的一些结果。

When used in the context of the basis path testing method, the value computed for cyclomatic complexity defines the number of independent paths in the basis set of a program and provides us with an upper bound for the number of tests that must be conducted to ensure that all statements have been executed at least once.

当在基本路径测试方法的情况下使用，用于圈复杂度计算出的值定义在一个程序设置的基础上独立的道路数量和为我们提供了一个上界的，必须进行测试，以确保数所有发言都至少执行一次。

We sat on the foredeck; because of the visionary effect of the highly upwards and we were riding the wind and scaring up to the skies. The boats lying leisurely at anchor here and there and the figures shifting about looked as if they were far away in a world below, and the blurred view also seemed like watching flowers through fog.

我们坐在舱前，因了那隆起的顶棚，仿佛总是昂着首向前走似的；于是飘飘然如御风而行的我们，看着那些自在的湾泊着的船，船里走马灯般的人物，便象是下界一般，迢迢的远了，又象在雾里看花，尽朦朦胧胧的。

In the term of sedimentary features of Neopaleozoic in south of North China Basin, lateral variation of sedimentary facies was studied selectively in Benxi-Taiyuan Formation, Shanxi Formation, Lower Shihezi Formation, Upper Shihezi Formation and Shiqianfeng Formation. Lithofacies paleographic features and the sedimentary evolutionary process of Late Paleozoic in south of North China Basin were worked also.

根据华北盆地南部上古生界的沉积特点，按本溪组—太原组、山西组、下石盒子组、上石盒子组和石千峰组5个层组分别开展了沉积相的横向变化对比研究，并以此为基础探讨了华北盆地南部晚古生代的岩相古地理特征及其沉积演化过程。

Found and recruited by the Lich King, Barathrum's uncanny speed and wraithlike powers have now been unleashed upon the Material Plane, his lantern able to project nether energy into enemies, sending them backwards with sudden force.

在被巫妖王发现并招至帐下以后，Barathrum不可思议的速度和幽魂般的力量得以在尘世释放。他的灯笼能向对手投射冥界的力量，将他们向后推送。

We also consider the problem when the number of calls emanating from each cell is large.

随后，我们给出了竞争比下界是2的证明。这样，我们提出的算法HYBRID在FAC中是最优的。

The corrosion product on the surface of 1N-939 alloys is found to be composed of chromium oxide and sulphide.

腐蚀层下没有贫铬现象，而出现贫钛区与沿晶界的内氧化物以及钇与钛的硫氧化物的分散质点。

Musical shows and entertainment celebrities have replaced the parades of armed and uniformed men marching in cadence or to a military band.

身穿制服的军人和着节奏或在军乐队伴奏下游行的活动已被精美的彩车。音乐表演以及娱乐界名人所替代。

MagiQuest noobs file into the vine-covered training room to watch a video of a bearded Gygaxian wizard who lays out the rules of the game.

魔法界探索的愣子们排队进入藤蔓覆盖的训练室观看络腮胡的法师划下游戏的道道儿。

In this paper,we use the method of the estimated characteristic function to estimate a lower bound of the first eigenvalue on compact Riemann manifold.

本文利用特征函数梯度估计的方法对紧致Riemann流形上的第一特征值的下界进行了估计。
