两趾的

The primitive characteristics include long tail with more than 20 caudal vertebrae, which are surrounded by thin rod-like extensions of the zygapophyses and chevrons, and the fifth toe bearing two long digits, whereas the derived characteristics include an elongated skull with antorbital and nasal openings fused into a large nasoantorbital fenestra, long cervical vertebrae with reduced or absent cervical ribs. The length ratio of the wing metacarpal to the humerus is between the basal pterosaurs and pterodactyloids.

它既具有原始类群的特征：比如尾长，多于20节尾椎椎体，且尾椎椎体由极度加长的、纤细的前后关节突及脉弧所包裹，构成一僵硬的尾部，第五脚趾具有两个长的趾节；又具有进步类群的特征：比如头骨加长，鼻孔和眶前孔愈合为一大的鼻眶前孔，颈椎椎体长，没有或者颈肋退化；翼掌骨与肱骨的比率介于原始类群和进步类群之间。

His thick tail shifted anxiously as he settled his weight evenly between both leonine legs and ground the toes of his hooves into the solid stone masonry.

那厚实的尾巴焦急地摆动，他把全身的重量均匀地落在两条狮子一样的腿上，把蹄趾踏在结实的石地板。

Based on the Peterson type formula and the Topper type formula, two formule of effective stress concentration factor are developed.

本文考虑了材料、受载形式、尺寸、错位量、焊接残余应力以及焊趾根部短裂纹对错位板节点疲劳强度的影响，在Peterson公式和Topper公式的基础上，分别建立了两个估算这类节点疲劳强度的有效应力集中系数的公式。

"Any of the tailless, anthropoid primates of two families: Hylobatidae (the lesser apes: gibbons and siamangs) and Pongidae (the great apes: chimpanzees, bonobos, orangutans, and gorillas)."

无尾、类人灵长类的动物，分有两大科：长臂猿科(较小的类人猿：长臂猿和合趾猿)和猩猩科(较大的类人猿：黑猩猩、小黑猩猩、猩猩和大猩猩)。

The birds that the two girls had brought in were duly returned to the yard, and the process was repeated till all the pet cocks and hens had been submitted to the old woman - Hamburghs, Bantams, Cochins, Brahmas, Dorkings, and such other sorts as were in fashion just then - her perception of each visitor being seldom at fault as she received the bird upon her knees.

两个姑娘把带来的鸡一只只送回院子，不断重复着带来送去的程序，一只又一只地把老夫人所宠爱的公鸡和母鸡送到她的面前——如汉堡鸡、短脚鸡、交趾鸡、印度大种鸡、多津鸡，还有其它一些当时流行的各种各样的鸡——当每只鸡放到老夫人的膝上时，她都能认出来，而且几乎没有认错的。

Larger of two tall fast-running flightless birds similar to ostriches but three-toed; found from Brazil to Patagonia.

两种奔跑快速但不会飞的鸟中的较大者，类似驼鸟但具有三趾；产于从巴西到巴塔哥尼亚的地区。

Smaller of two tall fast-running flightless birds similar to ostriches but three-toed; found from Peru to Straits of Magellan.

两种奔跑快速但不会飞的鸟中的较大者，类似驼鸟但具有三趾；产于从秘鲁到麦哲伦海峡的地区。

This paper uses LIZHENG to check the stability of the retaining wall. Both of them aren't meet the requirements. And the bearing capacity at the toe of the retaining wall which belongs to AB slope isn't meet the requirement.

利用理正软件对边坡的挡墙进行稳定性验算：两段边坡下挡墙的抗滑移稳定性均不满足要求，且AB段挡墙墙趾处的承载能力也不满足要求。

A representative from this alien species is a bipedal humanoid with blue-gray skin, double rows of cheekbones, a long, tapered proboscis, four conelets atop the skull, three-fingered hands, and a pair of dark, glassy eyes.

这个人形种族的代表性特征是：两足，皮肤灰蓝，双层的颊骨，尖细的长喙，颅顶生有四个锥角，手上三趾，眼睛黑色透明。

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。
