爪

This allows the crab to insert a large toothlike appendage on its right-hand claw into the opening, thus cracking the snail's shell.

这样就可以把它右爪那边象牙齿样的东西刺进蜗壳口从而弄碎蜗壳。

Due to the fact that every time when I came home, he would knock at the door with his chubby tylopod claws, so I named him KouKou.

由于每次回家时，它总是喜欢用敦实而且肉感十足的两只前爪拍打门板，所以后来我便给它起了一个名字：叩叩。

The core catcher serves to grip the bottom of the core and, as tension is applied to the drillstring, the rock under the core breaks away from the undrilled formation below it.

岩心爪用于抓住岩心的底端，当施加拉力给钻柱时，使得岩心以下的岩石与下部尚未碑钻进的地层脱离。

There's a condition known as main de singe , or monkey's hand, which is when the thumb makes a straight line with the fingers and is termed ''unopposable''.

有一种情况被称之为猴爪，大拇指和其他手指长成一排，专业术语称之为&与其他手指不相对的&。

Indeed, in a test in November along a southern Mozambique railway that was heavily mined during this country's 17-year civil war, teams of three giant pouched rats found every one of 20 live mines in a previously unsurveyed 4,300-square-foot swatch of land.

套着红色甲胄的&万吉罗&是只2岁的雌鼠，线绳刚拉了一半，它突然停了下来，然后又转身嗅了嗅，随即伸出前爪猛挠一块红土。驯兽师马加扎马上拉响金属环，&万吉罗&慢慢向他走近领赏--香蕉。

Two molecular forms of Xenopus hatching enzyme, 60kD and 40kD molecules, was obtained during preparation and purification. Both of them were verified as the hatching enzyme molecules, using anti GST UVS.2 antibody as the probe. 60kD molecule was digested or autodigested easily into 40kD molecule during purification. It was indicated that 40kD molecule was probably derived from 60kD molecule with its two CUB repeats lost, and the two CUB repeats may play an important role in recognizing and/or modifying of the molecular structure of vitelline envelope.

在分离纯化非洲爪蟾孵化酶时，得到了60kD和40kD两种分子，用孵化酶的特异性抗GST-UVS.2抗体进行Western杂交的结果证明二者均为孵化酶分子。60kD分子很不稳定，在纯化过程中极易降解，40kD分子可能是由60kD分子经过降解或自身降解丢失了两个CUB重复区而形成的，而CUB重复区很可能在对受精膜分子结构的修饰或改造中具有重要作用。

Nearly 70%of X.tropicalis GPCRs are represented by three types of receptors thought to receive chemosensory information from the outside world: olfactory,vomeronasal 1 and vomeronasal 2 receptors.

3不管是从受体的种类还是数量来看，热带爪蟾中的G蛋白偶联受体更趋近于高等动物，兼有水生和陆生特点，表现出从水生到陆生的过渡形态。

The whiskered biped stands about 2.2 meters tall, had three-clawed hoof-like hands, and said very little.

这个有胡子的两足动物站立时约2.2米高，手像蹄子而有三个爪，沉默寡言。

In pterosaurs a greatly elongated fourth finger of each forelimb supported a winglike membrane. The other fingers were short and reptilian, with sharpclaws.

翼龙每个前肢的大大延长的第四指支撑一个翅膀状的薄膜，其它指头小，而且是典型的爬行动物式，有尖爪。

Most understory plants populations display aggre-gated spatial distributions.Daphniphyllum glaucescens,Eurya nitida,Schima superba,Ficus hirtaand Woodwardia japonica and so on have larger niche breadth.

老龄杉木林林下植物主要呈聚集的空间分布；虎皮楠、细齿柃木、木荷、三龙爪、狗脊等林下植物的生态位宽度较大。

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。
