For the np-hard problem of constructing minimum connected dominating set in ad hoc networks, this paper proposed a novel distributed mcds constructing algorithm called dmca. dmca constructed a mcds for ad hoc networks based on a maximal independent set. in dmca, each node only required the knowledge of its one-hop neighbors and there existed only one shortest path connecting two dominators these were at most three hops away.

摘 要：针对无线自组织分组网络中最小连通支配集创建np难问题，提出了一种分布式的最小连通集创建算法dmca.dmca基于最大独立集的构建，只需要周围一跳邻居的信息，在不超过三跳距离的一对支配节点之间找出一条最短路径。

Even before going into conservatorship, Fannie and Freddie were unique hybrids, and the envy of their rivals.

在政府监管这2家公司之前，他们就是独一无二的一对且受到很多对手的羡慕。

For each pair of phases, specify a constant restitution coefficient.

除了为每一对颗粒相之间的碰撞指定归还系数外，你也得为同相颗粒之间的碰撞指定归还系数。

The analysis of growth indicated that all strains could grow well at 4℃15℃ while they could grow poorly at 25℃30℃, and few of them could grow constrainedly at 37℃.

通过所分离出的嗜冷细菌的165 rDNA序列的比较分析，对嗜冷海洋细菌的特异165 rDNA序列进行了探索，并设计了一对引物。

Every one of those mothers loves and needs her daughter more than her daughter will love and need her someday, and we are, each of us, the only person on earth who is quite so consumingly interested in our child.

每一位母亲爱女儿和需要女儿的程度都超过将来某一天女儿对母亲的爱和需要。而我们当中的每一位母亲都是这个世界上惟一对孩子这样尽情关怀的人。原句中her daughter只出现一次，而在译文中，为了加强语气，需要重复。

This is contradict. Government is not stupid like that.

这是一对矛盾的，政府不会那么愚蠢。

The first movement opens with the cello alone; variations of its expansive main theme and a pair of contrasting secondary ideas give much cause to contrapuntal and melodic interplay between the two players.

第一个乐章以大提琴单独开始；它主调的变奏和一对作对比的副主题造成了两个乐手间的对位和主调交错。

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
