小群

In a little bay she found a whole swarm of little mortals They were quite naked and splashed about in the water :she wanted to play with them ,but they fled in affright ,and a little black animal came —— it was a dog ,but she had never seen a dog —— and it barked at her so terribly that she became frightened ,and made out to the open sea .

在一个小河湾里她碰到一群人间的小孩子；他们光着身子，在水里游来游去。她倒很想跟他们玩一会儿，可是他们吓了一跳，逃走了。于是一个小小的黑色动物走了过来——这是一条小狗，是她从来没有看到过的小狗。它对她汪汪地叫得那么凶狠，弄得她害怕起来，赶快逃到大海里去。

In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。

We followed tracks and signs of a large group of lion cubs that moved considerable distances, without the guidance or protection of adults. There were approximately ten cubs, and from the size of their spoor, they were no older than a year. These were unusual observations. Generally, lionesses give birth to small litters of 2 – 3 cubs, although they do occasionally synchronise their oestrus cycles and produce litters about the same time. However lion cubs, of that age, are mostly in the company of adults. Textbooks and the scientific literature suggest that one-year-old lions are dependent on the adult lionesses of their pride, and could not survive on their own.

我们跟踪由一大群幼狮留下足迹的其他记号，这些狮子没有其他成年狮子陪同和保护，粗略估计，这群狮子的数量接近10只，他们足迹的尺寸显示他们不会超过1岁，这是不常见的，通常情况下，母狮会生下至少2～3头幼崽，但也有个别例外的时候，然而在这个年龄段的幼狮大都有"母亲"陪同，许多书上介绍，1岁大的小狮在离开狮群母狮的照顾后是无法生存的。

According to the theory of wavelet transformation, the singularities of the ECG signal are corresponding to the series of maximum-minimum pairs. The algorithm detects the onsets of Q wave at the scale 3 detail and offsets of T wave at the scale 4 detail. So the duration of QT is calculated by onset of Q wave and offset of T wave.

根据小波变换的原理，心电中的奇异点在变换后将产生一个模极大值和模极小值对，在小波变换3尺度上检测出QRS波群的起点，在小波变换4尺度上检测出T波终点，从而确定QT间期。

The results of the phylogenetic cladograms indicated that Apanteles adoxophyesi Minamikaws and Apanteles angaleti Muesebeck are monophyletic group, Apanteles adoxophyesi Minamikaws % Apanteles angaleti Muesebeck and the remain 8 species make up a monophyletic group or paraphyletic group.

支序系统学研究结果证明安氏绒茧蜂Apanteles angaleti Muesebeck和茶小卷蛾绒茧蜂Apanteles adoxophyesi Minamikawa存在着亲缘关系，并形成单系群，与其它几种绒茧蜂形成姊妹群关系或并系群关系。

Vallisneria spinulosa maintained high levels of genetic variation both at the species and at the population level. Partitioning of genetic diversity revealed a surprisingly low population differentiation as compared to other hydrophilous angiosperms.

利用等位酶和开发的微卫星标记研究了刺苦草在长江中下流域的遗传多样性和遗传结构，研究结果表明，刺苦草在居群水平和种水平都具有高的遗传多样性；居群间遗传分化程度非常小；居群间历史上存在长距离基因流。

The contributions of photon radiations are ignored because they are negligible compared to the contributions of the particle radiations, or can be calculated and added to the S-values using MIRD formulae.

如果细胞群较小，则光子的剂量贡献忽略不记。细胞群中每个细胞内的放射性活度相同。计算得到细胞群中各个周围细胞中心到靶细胞中心的距离和周围细胞中的核素对靶细胞的剂量贡献。

The proposed algorithm incorporates two methods for the niching techniques: first, different algorithms are used for the evolvement of main swarms and sub-swarms; different sub-swarm with a main swarm is distinguished using clustering method.

提出的算法组合了两种方法来实现小生境技术的思想：第一，采用多种群策略实现全局和各子微粒群按不同的PSO算法进化：第二，采用聚类算法区分微粒群中存在的不同子微粒群。

An illustration of the world under the sea serves as the background for one of the souvenir sheets, and a photo of an underwater landscape serves as the background for the other. The stamps feature Nemo (a clownfish and star of the film), Tad (a long-nosed butterflyfish), Sheldon, Squirt, Peach, Bubbles, a school of sea turtles, Dory, and Pearl. These small squares of stamps spread joy and happiness with the colorful undersea world they capture. The set is well worth collecting and treasuring.

Phylogenic analysis based on entire S1 gene sequences showed that majority isolates clustered together with the close phylogenetic relationships. Therefore, we researched pathogenicity of the selected isolate IBV CK/CH/LDL/05II in this group, Pathogenic study showed that this virus caused 100% morbidity and 54.5% mortality to 15-day-old specific-pathogen-free.The kidneys from the dead chickens showed the predominant gross lesions which were pale, mottled, and swollen. The renal tubules and ureters were distended with excess urates.

经S1基因系统进化树分析发现，本实验所分离的大多数IBV毒株(8/12)分布于同一基因进化群内，并且亲缘关系较近，因此，我们对此群中IBV毒株CK/CH/LDL/05II的致病性进行研究，以10~(5.5)×EID_(50)/0.1ml的病毒接种15日龄的SPF雏鸡，鸡群发病率为22/22(100%)，死亡率为12/22(54.5%)，死亡鸡以肾脏肿大、苍白、外观呈现典型的&花斑肾&，肾小管和输尿管扩张并且有尿酸盐沉积为主要病理变化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
