Based on the analysis on brachiopod fossils of the late middle Permian, the brachiopod extinction in The Lopingian event of late middle Permian in this area can he divided into two sub screens: the first screen in the end of earlier Wushisanti Subage and the second screen in the end of later Daozuanyan Subage. The second screen's extinct scope is larger than the first screen's.

通过川渝地区中二叠世晚期的腕足动物化石资料的研究，表明本地区中二叠世晚期的乐平世事件中腕足动物的灭绝可划分为前后2个不同的次级幕：早期的五十三梯亚期之末的第一幕和晚期的倒钻岩亚期之末的第二幕，且第二幕的灭绝规模要比第一幕更大。

Congenital Preauricular Fistula (MIM 128700) is a common auricular abnormality, the incidence of which is around 1%. The formation of CPF is closely associated with embryological development of the auricle, which is developed from the first and second branchial arches.

先天性耳前瘘管（MIM 128700）是耳鼻咽喉科常见的遗传性疾病，其患病率接近1％，一般认为是胚胎期形成耳廓的第一、第二腮弓的六个小丘样结节融合不良或第一腮沟封闭不全所致。

Let us not weary of repeating, and sympathetic souls must not forget that this is the first of fraternal obligations, and selfish hearts must understand that the first of political necessities consists in thinking first of all of the disinherited and sorrowing throngs, in solacing, airing, enlightening, loving them, in enlarging their horizon to a magnificent extent, in lavishing upon them education in every form, in offering them the example of labor, never the example of idleness, in diminishing the individual burden by enlarging the notion of the universal aim, in setting a limit to poverty without setting a limit to wealth, in creating vast fields of public and popular activity, in having, like Briareus, a hundred hands to extend in all directions to the oppressed and the feeble, in employing the collective power for that grand duty of opening workshops for all arms, schools for all aptitudes, and laboratories for all degrees of intelligence, in augmenting salaries, diminishing trouble, balancing what should be and what is, that is to say, in proportioning enjoyment to effort and a glut to need; in a word, in evolving from the social apparatus more light and more comfort for the benefit of those who suffer and those who are ignorant.

我们应当不厌其烦地反复提出：要最先想到那些没有生计的痛苦民众，为他们减少困难，让他们得到空气和光明，爱护他们，扩大他们的视野，使他们感到灿烂辉煌，用种种形式为他们提供接受教育的机会，为他们提供劳动的榜样，而不是游手好闲的榜样，减轻他们个人负担的压力，增加他们对总目标的认识，限制穷困而不限制财富，大量创造人民共同劳动的天地，象布里亚柔斯①那样，把一百只手从四面八方伸向受压迫和软弱无力的人，为这一伟大职责运用集体的力量，为所有的胳膊开设工厂，为所有的才能开办学校，为所有的智力设立实验室，增加工资，减轻惩罚，平衡收支，也就是说，调整福利与劳动之间和享用与需求之间的比重。总之，要使社会机器为受苦和无知的人的利益发出更多的光明和更多的温暖，使富于同情心的人不忘记这些，这是人间友爱的第一义务，使自私自利的人懂得这些，这是政治的第一需要。

First and second bristle packets contact and generally cover, respectively, the first and second areas.

第一和第二硬毛束分别与该第一和第二区相接触并且大致覆盖在该区上。

It was first performed at Sadler's Wells in London on June 7 , 1945 , conducted by Reginald Goodall and was the first of Britten's operas to be a critical and popular success.

这是第一次演出，在萨德勒的水井，在伦敦举行的 1945年 6月7日进行，是第一家的（ Britten的歌剧，是一个关键的和流行的成功。

A first packet is broadcast from a first network device to other network devices that participate in the network.

从第一网络设备向参加网络的其它网络设备广播第一分组。

In different scenarios factors related with these characteristics will affect the performance of routing protocols in different way. So it is critical to understand the influence of different factors precisely for the purpose of achieving best cost efficiency. Most of the routing protocols depend on broadcasting to disseminate the route request message. But broadcast can always incur broadcast storm problems and consume considerable amount of network resources.

因此，无线自组织网络中路由查询的效能取决于两个方面：第一，路由协议设计能否满足上述第一个方面的静态特性需求，这也是无线自组织网络路由技术研究领域内受到广泛关注的热点；第二，能否准确把握网络中各种因素对路由协议性能的影响，使路由参数配置以及路由策略选择与具体的网络环境相适配，在路由查询效率与开销之间寻得最佳平衡。

Often a stock will advance to the 45 angle from the first top, fail to cross it, then decline and rest on the 45 angle from the first bottom –- then advance again, working up for a prolonged bull campaign between these parallel angles.

经常地，一只股票会向上走向从第一个高点开始的45角度线，且没能向上越过它，那么将下滑停在从第一个底部开始的45角度线上——然后再次向上，在这些平行的角度之间逐渐达到一个延长的牛市。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
