多足的

Traditional morphological studies have resulted in few solid conclusions regarding the monophyly and systematic position of Myriapoda within Arthropoda; the origin and evolutionary history of Myriapoda are also veiled by the sparsity of the group's fossil record.

基于表型性状的系统学研究中，多足动物亚门在节肢动物门中的系统分类和单系性等问题一直存在争议；化石记录的稀少又使多足动物的起源及演化历史变得迷雾重重。

Now doctors with the American College of Foot and Ankle Surgeons say Charcot foot's prevalence appears to be growing as more Americans get diabetes.

现在医生与美国高校的足部和脚踝外科医生说，夏足的流行似乎越来越为更多的美国人得到糖尿病。

Bloodless and many footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly moves with four feet and four wings: and, I may observe in passing, this creature is exceptional not only in regard to the duration of its existence, whence it receives its name, but also because though a quadruped it has wings also.

无血多足动物，不管装备翅膀还是足，移动依靠多于四个的运动点：像是，例如，蜉蝣依靠四足和四翅膀活动：并且，我可以顺便说一下，这种生物的特别不仅与它的生存周期、名称的由来有关，也因为它尽管是四足动物，但是也有翅膀。

All animals move alike, four-footed and many-footed; in other words, they all move cross-corner-wise.

所有的动物运动方式类似，四足的和多足的，换句话说，它们都用交叉动足的方法。

However, the ankle-foot orthosis limits musculation, and compresses trunk or limbs for a long time of period. To solve these problems, the structure design of original ankle-foot orthosis has been improved, and multiple functional, individualized and comfortable ankle-foot orthosis is developed.

但踝足矫形器也存在限制机体肌肉活动，使躯干或肢体长时间受压等问题，为了解决上述问题，科研工作者从矫形器的结构设计对原有矫形器进行改进，并研制出了符合个体要求的、多功能的、舒适的踝足矫形器。

This paper reviews recent advances in myriapod phylogenetics and presents a preliminary phylochronologic scheme of the evolutionary events in early my-riapods with the following observations: 1） Myriapoda might have diverged from its sister group during late Cambrian or earlier.

精确的多足动物亚门谱系发生关系以及谱系年代学细节还有待于进一步综合系统学、多基因和多重化石参照点的合理分析加以深入和完善，进而为早期陆地复杂生态系统的建立提供新的证据。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

The gene order data indicates that Hexapoda and Crussacea are more closely related with each other, and Chelicerata is closely related with Myriopoda. The results have conflicted with those of Boore (1998) results, but congruence with the results based on nuclear rRNA data.

线粒体基因组基因排列顺序数据显示六足动物与甲壳动物之间相似，螯肢动物与多足动物相似，这个结果和以前Boore(1998)对节肢动物线粒体基因组顺序分析结果不同，却和核rRNA数据的分析结果一致。

Currently applies to actual or reported in the literature of the foot wall-climbing robot usually based on simulation Principle or the six-legged quadruped walking and other agencies.

目前应用于实际的或文献报道的爬壁机器人的步行机构通常采用基于仿真原理的六足或四足等多足步行机构。

In the night, we often carried a flashlight and a bag to the stream in front of the house to catch frogs. Once, in order to give nutrition to my auntie who was then in the family way, I, together with my uncle, went along the stream for nearly two kilometers in order to catch more frogs. I was about to catch a big one crouching at a rock when a meter-long poisonous snake came into my vision. The snake was also attempting at the frog. It frightened me and my uncle greatly. However, panic was only our punishment. The snake went away and the frog escaped. Nevertheless, we got a bumper harvest that night. We caught about thirty frogs altogether, more than 5 kilograms.

到晚上打着手电、提一只布口袋，下到屋前的小溪里捉青蛙：一次为了给月子里的孃孃补补身体，我领着叔叔顺着小溪走了近两公里，捉青蛙捉得兴起，当我正想伸手去逮蹲在石头上的一只肥大的青蛙时，突然发现旁边一条一米多长的毒蛇吐着红舌头也伺机扑向这只大青蛙，着实把我和叔叔吓出了一身冷汗，好在有惊无险，毒蛇遛了，大青蛙也跑了，不过，那天夜里收获颇丰，共捉到三十多只青蛙，足有十余斤。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
