That means that there are really two hot blue-white stars orbiting so close that they cannot be separated in in a normal telescope, and their binary nature is discernible only through an analysis of their light.

这就意味着有两颗炙热的蓝-白星星在轨运行，它们如此的近以至于用正常的望远镜无法区分开，而且它们的双体性质只能通过对它们的光进行分析才能辨别。

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。

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。

They catch small animals as their food. Their favorite animals are deer and boars.

它们捕食小动物，而鹿和野猪又是它们的最爱。

This section will in detail explain how bots spread and how they are controlled by their masters.

本节将详细地解释僵尸工具如何扩散以及它们的主人如何控制它们。

These sea squirts, though alien in appearance, are chordates and thus close relatives to not only Homo sapiens but also about 17,000 kinds of fish; 70 or so species of dolphins, whales, seals, sea lions and otters; some 10 kinds of sea turtles; and about 80 kinds of sea snakes.

海鞘 这些海鞘虽然外观奇特，但是，它们是脊索动物，因此它们的近亲不光有智人，还有大约17000种鱼，以及约70种海豚、鲸鱼、海豹、海狮和水獭，还有约10种海龟和约80种海蛇。

Next I spoke to the devas and elementals, played them the tape, and asked them their opinion.

第二天我同提婆和元素谈话，向它们播放磁带，而征询它们的意见。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
