(verify)Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa) Infobox references Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. This colourless solid is the smallest peri-fused polycyclic aromatic hydrocarbon - one where the rings are fused through more than one face. Pyrene forms during incomplete combustion of organic compounds.Contents [hide]1 Occurrence and reactivity 2 Applications 3 Safety 4 References 5 External links [edit] Occurrence and reactivityPyrene was first isolated from coal tar where it occurs up to 2% by weight. As a peri-fused PAH, pyrene is much more resonance stabilized than its five-member-ring containing isomer fluoranthene. Thus, it is produced in a wide range of combustion conditions. For example, automobiles produce about 1 μg/km.Oxidation with chromate affords perinaphthenone and then naphthalene-1,4,5,8-tetracarboxylic acid. It undergoes a series of hydrogenation reactions, and is susceptible to halogenation, Diels-Alder additions, and nitration, all with varying degrees of selectivity.[edit] ApplicationsPyrene and its derivatives are used commercially to make dyes and dye precursors, for example pyranine and naphthalene-1,4,5,8-tetracarboxylic acid. Its derivatives are also valuable molecular probes via fluorescence spectroscopy, having a high quantum yield and lifetime (0.65 and 410 nanosecond, respectively, in ethanol at 293K). Its fluorescence emission spectrum is very sensitive to the solvent’s polarity, so pyrene has been used as a probe to determine solvent environments. This is due to its excited state having a different, non-planar structure than the ground state. Certain emission bands are unaffected, but others vary in intensity due to the strength of interaction with a solvent.[edit] SafetyAlthough it is not as problematic as benzopyrene, animal studies have shown pyrene is toxic to the kidneys and the liver.
英语单词词性a.ad.adv.adj.有区别么
说的这些都是表示单词词性的，adv.表示 副词adj.表示 形容词你说的及物动词和不及物动词用 vt. 和 vi 表示v. 表示 动词a. 是 adj. 的一种简略写法，也是表示 形容词ad.是 adv. 的简略写法，表示 副词。
词性标注（Part-Of-Speech tagging, POS tagging）也被称为语法标注（grammatical tagging）或词类消疑（word-category disambiguation），是语料库语言学（corpus linguistics）中将语料库内单词的词性按其含义和上下文内容进行标记的文本数据处理技术。
词性标注可以由人工或特定算法完成，使用机器学习（machine learning）方法实现词性标注是自然语言处理（Natural Language Processing, NLP）的研究内容。常见的词性标注算法包括隐马尔可夫模型（Hidden Markov Model, HMM）、条件随机场（Conditional random fields, CRFs）等。
词性标注主要被应用于文本挖掘（text mining）和NLP领域，是各类基于文本的机器学习任务，例如语义分析（semantic analysis）和指代消解（coreference resolution）的预处理步骤。
词性标注是随着语料库的建立而提出的，在其发展初期是语料库中语法分析器（parser）的组件之一，词性标注的早期工作包括宾夕法尼亚大学（University of Pennsylvania）TDAP（Transformations and Discourse Analysis Project）项目中的语法结构模型 。
1971年，Barbara B. Greene和Gerald M. Rubin以Klein and Simmons (1963)为基础开发了词性标注系统TAGGIT，并首次对大规模词库Brown Corpus进行了词性标注。
用英语介绍地震知识
。。。本来是第2个回的。回完了才想起来没把中文的发上。可是在回复中又显示不出我的回复。半天才有。。。害我等了半天才重新编辑。希望可以帮到你吧。Understood that the earthquake and the earthquake protect the general knowledge 了解地震与地震防护常识 (1) earthquake is the common natural phenomenon 地震是常见自然现象 The earthquake and daily sees the wind and rain, the thunder and lightning are the same, is one kind of more universal natural phenomenon. Statistics indicated that the world approximately has 5,000,000 times every year the earthquake, but 99% above earthquakes are the small earthquakes, the people are not easy to feel. But the intense burst characteristics earthquake often causes the human to be unexpected, thus causes the personnel casualty and the huge economic loss. 地震和日常所见的风雨、雷电一样，是一种较为普遍的自然现象。据统计，全世界每年约发生500万次地震，不过99％以上的地震是微小地震，人们不容易感觉到。但强烈的突发性地震往往使人猝不及防，从而造成人员伤亡和巨大的经济损失。 (二) earthquake’s origin 地震的成因 The earth interior material does not stop the movement, will have an function in the rock layer tremendous strength. When this strength accumulates to the certain extent, may cause some crag the level to have, the distortion curving. Once the rock layer cannot withstand this kind changed, will have the sudden breakage, moving out of place, caused the intense vibration, this kind of vibration was the earthquake which we usually said. The earth interior has earthquake’s place to call the center of origin, the ground to be apart from the center of origin recent place to be called the epicenter earthquake’s size to be possible to use the magnitude and the earthquake intensity weighs. When magnitude expression earthquake emit energy size; The intensity expressed that earthquake degree which destroys to the ground. 地球内部物质不停运动，会产生一股作用于岩层的巨大力量。当这股力量积累到一定程度时，可使一些岩层发生弯曲、变形。一旦岩层承受不了这种变化的时候，就会发生急剧的破裂、错动，引起强烈振动，这种振动就是我们平时所说的地震。 地球内部发生地震的地方叫震源，地面距震源最近的地方叫震中地震的大小可以用地震震级和地震烈度来衡量。震级表示地震时释放能量的大小；烈度表示地震对地面破坏的程度。(三) Earthquake’s type 地震的种类(1) Tectonic earthquake 构造地震The tectonic earthquake is the earthquake which the earth structure movement causes. When the composition earth’s crust’s rock layer under the crustal stress function, has the incline or the bending strain, the local stress continues to strengthen, accumulates to surpasses the limit which the rock layer can withstand, along rock layer structure weak place. Has the break or the dislocation suddenly, causes the energy which accumulates for a long time to release suddenly, and to all around disseminates by the earthquake wave form causes the ground vibration. 构造地震是地球构造运动引起的地震。组成地壳的岩层在地应力作用下，发生倾斜或弯曲变形， 当地应力继续增强，积累到超过岩层所能承受的限度时，沿着岩层构造薄弱的地方。突然发生断裂或错位，使长期积累起来的能量急剧地释放出来，并以地震波的形式向四周传播而引起地面的振动。 (2) Volcanic earthquake 火山地震The volcanic earthquake is causes by the volcanic eruption. The volcanic earthquake mainly has two kinds: One kind when is volcanic eruption, because the rock magma impact earth’s crust or causes the earthquake which the local area rock layer occurs distorts and dislodges causes. After another kind is volcanic eruption, because the massive rock magma lose, the subsurface pressure reduces or the underground deep place supplies is inferior to, to present the cavity, thus causes the earthquake which the above cover’s rock layer break or the collapse produce. 火山地震是由火山爆发而引起的。火山地震主要有两种：一种是火山爆发时， 由于岩浆冲击地壳或使局部地区岩层发生变形和变位而引起的地震。另一种是火山爆发后，由于大量岩浆损失，地下压力减小或地下深处补给不及， 出现空洞，从而引起上面覆盖的岩层断裂或塌陷而产生的地震。 (3) The depression earthquake depression earthquake is the local earthquake which causes as a result of the underground limestone cave or the mine worked-out section’s downcast. 陷落地震陷落地震是由于地下溶洞或矿山采空区的陷落而引起的局部地震。China earthquake intensity 中国地震烈度 Ⅰ 1.9 Does not have the feeling, only the instrument can record 无感，仅仪器能记录到 Ⅱ 2.5 The individual sensitive person in completely static has the feeling 个别敏感的人在完全静止中有感 Ⅲ 3.1 The indoor small number of people have the feeling in the static, the suspension swings slightly Ⅳ 3.7Indoor most people, the outdoor small number of people have the feeling, suspension swinging. Not the steady household utensils make noise Ⅴ 4.3Outdoor most people have the feeling, the domestic animal do not go home, the windows and doors make noise, the wall surface presents the crack 室外大多数人有感， 家畜不回家， 门窗作响，墙壁表面出现裂纹 Ⅵ 4.9The human stands not steadily, the domestic animal escapes, the household utensils turn fall, crude shed lodging damage, steep ridge landslide 人站立不稳，家畜外逃，器皿翻落， 简陋棚舍损坏，陡坎滑坡 Ⅶ 5.5 The house slight damage, the memorial arch, the chimney damage, the surface presents the crack and spurts Sha Maoshui 房屋轻微损坏，牌坊、烟囱损坏，地表出现裂缝及喷沙冒水 Ⅷ 6.1The house has the damage, minority roadbed landslide, underground duct breakage 房屋多有损坏，少数路基塌方，地下管道破裂 Ⅸ 6.7 The house majority destructions, minority fall, avalanches and so on memorial arch, chimney, the railway rail is curving 房屋大多数破坏，少数倾倒，牌坊、烟囱等崩塌，铁轨弯曲 Ⅹ 7.3 The house falls, the path destruction, the mountain stone massive avalanches, the water surface very rough seas throw the shore 房屋倾倒，道路毁坏，山石大量崩塌，水面大浪扑岸 Ⅺ 7.9 The house collapses massively, roadbed dike big Duan Benghui, the surface has the very sweeping change 房屋大量倒塌，路基堤岸大段崩毁，地表产生很大变化 Ⅻ 8.5 All building universal destruction, the terrain changes fiercely, the zoology and botany suffers destroys 一切建筑物普遍毁坏，地形剧烈变化，动植物遭毁灭(四) Earthquake’s destruction 地震的破坏 When earthquake, because ground succession large scale vibration, thus has the huge destructive effect, causes buildings and so on house, bridge, railroad, road, reservoir to suffer the degree different destruction. 地震时，由于地面连续发生大幅度的振动，从而产生巨大的破坏作用，造成房屋、桥梁、铁路、公路、水库等建筑物遭受程度不同的破坏。 (五) Earthquake omen 地震前兆 The earthquake, before specially the violent earthquake occurs, the general meeting appears…`abnormal phenomena. The people observe - to occur with the earthquake have the close contacting abnormal phenomenon to be called the earthquake omen. 地震，特别是强地震发生之前，总会出现…‘些异常现象。人们把观察到的—些与地震发生有密切联系的异常现象称为地震前兆。 (1) The ground water is unusual 地下水异常 (2)The animal is unusual 动物异常 (3) Flashes of light preceding an earthquake and earthquake sounds 地光和地声The flashes of light preceding an earthquake and the earthquake sounds are the earthquake eve either when the earthquake makes luminous and the sound from underground or the ground, is important near shakes the omen. Before shaking, the flash, the sound production, shines, sees this sentiment, suitable decisive, fast motion, few dangers. 地光和地声是地震前夕或地震时从地下或地面发出的光亮及声音，是重要的临震预兆。临震前，一瞬间，地发声，又发光，见此情，宜果断，速行动，少危险。 (六) Earthquake prediction issue 地震预报的发布The country practices the unification issue system to the earthquake prediction. The earthquake short-term forecast and near shakes the predict that by the province, the autonomous region, the municipality people’s government the procedure issue which stipulated according to the State Council. Other any unit and individual has no right to issue the earthquake prediction news. 国家对地震预报实行统一发布制度。地震短期预报和临震预报，由省、自治区、直辖市人民政府按照国务院规定的程序发布。其他任何单位和个人都无权发布地震预报消息。 (七) Before how to prepare for earthquake’s 怎样做好地震前的准备 1 .Understands the earthquake knowledge, grasps the quakeproof emergency procedures了解地震知识，掌握防震应急措施。 2. Believes the science, opposes to blindly believe, does not readily believe the earthquake rumor相信科学，反对迷信，不轻信地震谣言。 3.

海洛英为什么和英雄一个词
其实英雄和海洛英并非同一个词，hero 英雄heroine 女英雄heroin 海洛英英美国家有语言读物专门提过这个问题，提醒人们不要混淆，并明确指出海洛英与英雄的拼写虽然近似，但毫无关系。以下是一段该说明的摘录：This article is about the type of person known as a “hero“. For other meanings of this term, see hero (disambiguation). “Heroine“, the feminine form of “hero“, should not be confused with heroin, the drug.海洛英的学名是Diacetylmorphine，heroin是后来大街上的毒贩起的名字，因广泛流传而成为现在的通用称呼，它实在与英雄无关。
