它们的

I couldn't get back home; it was too far, and turning cold; but I found some tigers, and nestled in among them and was most adorably comfortable, and their breath was sweet and pleasant, because they live on strawberries.

我走不回家了，路途太远，天气此时寒意逼人；可我发现了几只老虎，在它们中间躺下来实在舒服极了它们的呼吸闻起来格外芬芳、令人惬意，因它们靠吃草莓为生。

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族，全部是固体金属，它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素，它们的外围两层的电子均是5d16s2，而外围第三层的f轨道电子却从零增加到14个，所以外围电子结构为4f0－145d16s2，而使这些元素氧化数均为＋3，化学性质极为接近，提炼时很难分开，它们的矿石又大多是多种元素混在一起的，更增加提纯难度，它们的原子序数为57－71，核内质子数逐个增加，因而对核外电子引力也不断增强，使原子半径随原子序数Z增加而减小，这就使镧系元素收缩、离子半径也缩小，这也使得Zr和Hf，Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似，以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似，因而称这六个元素为铂系元素。

Fertile areas to be mined include the Lothian and Fife coasts in Scotland, Robin Hood's Bay, Lulworth Cove in Dorset (which, along with East Devon, is known as the Jurassic coast) and the Pembrokeshire coast in Wales.

在德文郡也发现了它们牙齿的样本。调查局有不少这样的标本。"它们是我的最爱。"他说："因为它们的进化非常迅速，对于确定岩石的年代非常有帮助。由于它们的颜色会根据地热变化，它们还可以作为天然气和石油开采的依据。"

The YAHOOS were the most filthy, noisome, and deformed animals which nature ever produced, so they were the most restive and indocible, mischievous and malicious; they would privately suck the teats of the HOUYHNHNMS' cows, kill and devour their cats, trample down their oats and grass, if they were not continually watched, and commit a thousand other extravagancies.

&雅虎&是大自然所生的一种最肮脏、最有害、最丑恶的动物，因此它们最为倔强而又不可驯服，恶毒而又惹事生非；要不是经常看管着它们，它们就偷偷地去吮食&慧马&养的母牛的奶，杀死并吃掉它们的猫，践踏坏它们种的燕麦和青草；还有许多别的无礼行径。

Because they grow in clusters, and their intertwining roots help them support one another against storms.

因为它们集结一起生长，它们的根彼此缠绕，这樣它们便能在风暴中彼此支持。

Because they grow in clusters, and their intertwining roots help them support one another against storms.

因为它们集结一起生长，它们的根彼此缠绕，这样它们便能在风暴中彼此支持。

After plasmodia infect a blood cell, they send out clusters of sticky proteins to the cell surface, enabling them to attach to blood vessels and escape destruction by the host's spleen while they replicate.

疟原虫感染血细胞后，它们会向细胞表面释放出一系列粘性蛋白质，使其能够附着在血管上，以便逃避它们复制时宿主脾脏对它们的破坏。

We get a class of refinable distributions which have localpolynomial property and are globally linear independent but are locally lineardependent,So that when M＞N,the Daubechies type scaling functions〓have localpolynomial properties and are globally linear independent but locally lineardependent.

给出了一类细分方程，它们的解具有局部多项式性质并且它们是整体线性无关的但是它们是局部线性相关的。从而得到了当〓时，Daubechies型尺度函数〓具有局部多项式性质并且它们是整体线性无关的但是它们是局部线性相关的。

Force-fed, they are kept in cages which restrain them from moving about, so as to fatten them up and make the meat comparably tender.

强制给鸭子喂食并且把它们关在笼子里，限制它们的活动，从而使它们长得更加肥大，还有肉质也十分鲜嫩。

The paper establishes stress-model about the roller bra ke tester and the flat brake tester, Moreover analyzes the model and compares their strongpoint and disadvantage t hrough simulating their actual work condition, At last educe their use range and their integrated use in brake force test.

建立了滚筒制动试验台和平板制动试验台受力分析模型，并通过模拟它们的实际工况来分析它们的受力模型，比较它们各自的优缺点，最后得出了它们的使用范围，以及在制动力检测时它们的结合使用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
