The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

The boy had given him two fresh small tunas, or albacores, which hung on the two deepest lines like plummets and, on the others, he had a big blue runner and a yellow jack that had been used before; but they were in good condition still and had the excellent sardines to give them scent and attractiveness.

孩子给了他两条新鲜的小金枪鱼，或者叫做长鳍金枪鱼，它们正像铅垂般挂在那两根最深的钓索上，在另外两根上，他挂上了一条蓝色大鲹鱼和一条黄色金银鱼，它们已被使用过，但依然完好，而且还有出色的沙丁鱼给它们添上香味和吸引力。

I loved them. Their black body betrayed that they had experiences a lot of springs and autumns.

我爱它们。它们那黑黝黝的外表向我们揭示了它们经历的那曾经沧桑的岁月。

Not only we must pay attention observe their itself the basic significance, must pay attention their meaning deep and broad symbol significance, because their symbolic significance often has the different characteristic in the different national language, some characteristics even constituted the people to extend, the figurative meaning later color avocations and the taboo to the process.

我们不仅要注意观察它们本身的基本意义，更要留心它们含义深广的象征意义，因为它们的象征意义在不同民族语言中往往有不同的特点，有些特点甚至构成了人们对经过引伸、转义以后颜色的崇尚和禁忌。

It also has two sets of barbels (whisker-like organs) on the upper and lower jaw, which help the fish hunt its prey in the murky waters of large lakes and slow-flowing rivers across Europe.

它们的上下颌上各长着一套触须，帮助它们在混沌的水域中捕捉猎物，因此它们的身影遍布欧洲的大湖以及水流不急的河流。

"These metals are similar chemically because their atomic structures are generally similar; all form compounds in which they have valence 3, including stable oxide s, carbides, and borides."

这些金属的化学性质十分相似，因为它们的原子结构通常相似；它们都可以与其它元素形成化合物，包括稳定的氧化物、碳化物、硼化物，它们在其中的原子价为3价。

The cactuses have long roots and they take their roots deep into the earth so that they can get the water from deeper,soil.

它们一般开小而白的花。尽管它们在沙漠里被忽视，但是它们从不放弃开花并且默默地点缀着沙漠。

From Mini Coopers to Beetles to Smarts, the difference is not just in the size but also the story behind them: Here's a brief history of these beauties

从Mini Coopers到Beetles再到Smarts，它们的区别不仅仅在于车身的大小，还包括它们背后的故事。接下来我们来分享一些它们的历史

In parallel to PN, chapter 4 defines a series of concepts for timed PNs with weak firing rules , gives generative approaches for state reachable graph and state coverable graph, and proves that WTPN is equivalent to its underlying net about liveness, boundedness and reversibility.

第三章除简介PN的基本知识，还分析了现有的四种确定性时间约束PN与其基网系统之间关系，指出了它们用于定性分析和性能评估时出现的一些问题及其产生的原因，比较了它们的异同并指出了一些现存关于它们的模糊认识以及由此产生的不妥结论，基于此提出并初步探讨了四种LDTCPN模型与其基网系统的关系。

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
