Chemical analyses of 43 brine samples for 9 brine-bearing aquifers or aquifer groups at 12 localities in the basin are presented in Table 19. 2. The localities sampled are also show n in Figure 19. 2，w hich are Anren，Moxi，Penglai，Longnu，Bajiaochang，Langjiang，Suinan， Laoguanmiao，Youguanding，Luojiaping，Dengguan，and Weiyuan. The aquifers or aquifer groups under consideration include sandstone w ith gypsum in the Guankou Formation of the Upper Cretaceous ( K2g or Guankou aquifer) ，sandstone in the Low er Jurassic ( Jlor Ziliujing aquifer) ，sandstone of the sixth，fourth，and second formation of the Xujiahe Formation of the Upper Triassic ( T3xj or Xujiahe aquifer) ，limestone of the Leikoupo Formation of the Middle Triassic ( T2l or Leikoupo aquifer ) ，limestone of the Jialingjiang Formation of the Low er Triassic ( T1j or Jialingjiang aquifer ) ，and limestone of the Upper Sinian ( Z2or Sinian aquifer) . Chemical analyses for brines from aquifers of Permian，Carboniferous，Devonian， Ordovician，and Cambrian Systems，are not important quantitatively，and are not presented here. Brines of Guankou aquifer are only found in Anren，and brines of Sinian aquifer，only in Weiyuan. Brines from Dengguan are a mixture of those from Leikoupo and Jialingjiang aquifers.Table19.2 Chemical compositions of subsurface brines in the Sichuan Basin (mg/L)continuedNmbersoflocationssampled:1—Anren;2—Moxi;3—Penglai;4—Longnu;5—Bajiaochang;6—Langjiang;7—Suinan;8—Laoguanmiao;9—Youguanding;10—Luojiaping;11—Dengguan; 12—Weiyuan. K2g—GuankouoftheUpperCretaceousSeries;J1—ZiliujingintheLowerJurassicSeries;T3xj— XujiaheGroupoftheUpperTriassic;T2l—LeikoupoGroupoftheMiddleTriassic;T1j—JialingjiangGroupoftheLower Triassic;Z2—theUpperSinian.The Sichuan Basin brines have between 70 g / L and 345 g / L total dissolved solids ( TDS) . Second，hydrochemical characteristics are connected with specific formations and are noteworthy. The TDS of the brines from Leikoupo and Jialingjiang carbonate aquifers in the central basin are the highest. Dissolved chloride ranges from 45 g / L to 202 g / L and constitutes more than 95% equivalent of the anions in all the brines. Sodium varies between 15 g / L and 120 g / L and accounts for more than 50 percent of the cations. Calcium is generally the second major cation in the brines. Calcium is commonly high in brines from Xujiahe and Ziliujing clastic aquifers. Dissolved strontium and barium concentrations are higher in brines from Xujiahe and Ziliujing clastic aquifers than those from carbonate aquifers of older age. Barium has not been detected in brines from Leikoupo and Jialingjiang carbonate aquifers. Dissolved sulfate and bicarbonate are generally low. Brines from Xujiahe and Ziliujing clastic aquifers have no sulfate，and sulfate content is high in brines from the Guankou aquifer. Bromide and iodide are usually high in the brines，with higher values in the Xujiahe and Ziliujing clastic aquifer brines. The bromide content in Guankou brines，however，is low. Brines from Xujiahe and Ziliujing clastic aquifers，where no evaporites have been found，are characterized by high concentrations of Ca，Sr，Ba，Br and I and lack of SO4. Brines from Leikoupo and Jialingjiang carbonate aquifers are characterized by low concentrations of Ca，Sr，Br，I and SO4，and lack of Ba. Brines in the Guankou aquifer have low concentration of Br. Brines in the Sinian aquifer have relatively high proportion of Li.Figure 19. 2 M ap show ing locations sampled and anticlines in the Sichuan Basin 1—Anren; 2—Moxi; 3—Penglai; 4—Longnu; 5—Bajiaochang; 6—Langjiang; 7—Suinan; 8—Laoguanmiao; 9—Youguanding; 10—Luojiaping; 11—Dengguan; 12—WeiyuanFigure 19. 3 is a Piper diagram based on all available data. The cation ternary shows a linear trend，form sodium dominated brines， to brines with higher relative proportions of calcium. The brines fall in two major clusters，one containing Na-Cl type brines from Leikoupo and Jialingjiang carbonate aquifers，the other containing Na·Ca-Cl type brines from Xujiahe and Ziliujing clastic aquifers. Brines from Guankou and Sinian aquifers also fall in the first cluster， indicating that they are of Na-Cl type.Figure 19. 3 Piper diagram show ing mole percentage of major ions in the Sichuan Basin brinesTo identify the possible origin and evolution of subsurface brines，Carpenter in 1978 demonstrated how TDS and chemical compositions of brines can be compared to those of evaporatively concentrated sea water Fisher and kreitler in 1987. used log-log plots of individual component concentrations versus Br of evapo-concentrated sea water to identify the origin of brines in the Palo Duro Basin and the Michigan Basin in the USA. Log-log plots of Br versus Cl and Na during evaporative concentration of sea water are thought to be the most useful. The log-log plots of Br versus Cl and Na for brines in the Sichuan Basin are shown in Figure 19. 4，with the sea-water evaporation trajectories. The brines from Leikoupo and Jialingjiang carbonate aquifers have Cl and Na compositions that fall near the sea-water evaporation trajectories. Marine evaporate conditions of deposition for Leikoupo and Jialingjiang are suggested by anhydrite and halite crystals; sea water was the original fluid for the Leikoupo and Jialingjiang brines. Brines from Sinian aquifer also originated from sea water. Although brines from Xujiahe and Ziliujing fall near or a bit below the trajectories ( Figure 19. 4) ，suggesting that the brines have been concentrated beyond the onset of halite precipitation，we cannot draw the conclusion that the Xujiahe and Ziliujing brines originated from evaporated sea water. The strata of Xujiahe and Ziliujing consist of continental sediments and contain no evaporites. Thus，the brines from Xuijahe and Ziliujing aquifers are not sea water in origin. Figure 19. 4 also shows that the brines from the Guankou aquifer were derived typically from subsurface dissolution of salt-bearing formations.

Claude A Debussy was one of the modern composers representing France.Influenced by the impressionism artists and symbolic poetry, he became the first ancestor of impressionism music by creating a unique musical grammar by himself. This Article aims at the research on the musical characteristic and the unique composition technique of Claude A Debussy by the analysis of presentation skills in the composition of pour le piano, and putting forward the theoretical direction while performing his category, so as to help the performers present the composition intention successfully.

在我的作文中，我总是想造一些复杂的，包含不同类型结构的句子，通常我会以为我将得到一个高分。然而，结果是分数低于我平均水平3-4分 。此外，我的书写相当好。我真的不知道是何原因。或许我的策略错了。你能给我一条捷径让我得到高分吗？ 我觉得英语作文要力求简洁，符合西方人的思维，不应一味求复杂，直截了当才是王道。我们的情况相似，我也曾吃过亏，希望你能改正，并快速提高！ If you have interest ,we can be English partners ! QQ ；1113123033

relative clause是指的是关系从句。关系从句的理解与翻译人们习惯称由关系代词that，which，who，whom，whose和关系副词when，where等引导的从句为“定语从句”，认为这种从句的功能同汉语定语相当，只不过英语的定语从句后置，汉语的定语前置罢了。但随着对语言认识的不断深入，人们发现很多这样的从句不能用定语来翻译。让我们先看一例：1. Kennedy was rushed to a hospital where he died immediately.若拘泥于“简短的定语从句可译为汉语前置定语”的观点，该句子就可能会被译为：肯尼迪被急忙送到一家他很快就死的医院。译文听上去荒谬可笑，仿佛送医院的目的是为了“很快就死”，这显然有悖原意。这里“where”起过渡连接的作用，相当于“and there”，在语义上属另一新层次，绝无修饰，更无限制“怎样的医院”之意。从句中“died”这一动作发生于主句中“was rushed”的动作之后，进一步交待了事情发展的结果。可见，这种结构难用“定语从句”来解释。所以，例1应译为：肯尼迪被急忙送到一家医院，在那里他很快就死了。让我们再多看几个例子：2. When he was still a little boy, Jack London wrote some compositions which were praised by his teachers.杰克·伦敦还是小孩时，他写的一些作文就受到老师的赞赏。(不宜译为：……他就写受到老师赞扬的作文。)3. I met the boatman who then took me across the ferry.我遇到了那位船夫，他将我渡到对岸。(不宜译为：我遇到那位将我渡到对岸的船夫。)

热心网友The advantages of writing compositions by computerNowadays, an increasing number of students, especially university students use personal computer to write compositions. Whether it is beneficial to us? The opinions vary from person to person. I hold the aspect that writing compositions by computer brings a lot of advantages to us.Firstly, it is more efficient than writing by hand. According to the present data, the fastest speed of typing is over 500 words per minute, while the highest speed of handwriting is only 90 words per minute. Secondly, it brings a lot of convenience while writing by computer. For example, we can avoid some original mistakes, such as the spelling, punctuation, and some grammar mistakes. Besides, we can e-mail our compositions to teachers, so teachers can check our compositions instantly. In addition, it is easier for us to save our compositions in files. Last but not least, it saves many resources like paper and ink. If we want to write a good composition, we have to correct it again and again. For example, we are writing a TEM4 composition by hand. we make many kinds of mistakes, so we have to waste a lot of paper while consummating it. However, if we write it by computer, we only need to revise it on a computer, without wasting any paper. Writing compositions by computer not only helps us search information, but also does good to thinking visually. Computer is really an excellent writing tool for us, which can help us explore our further writing.

With the booming information technology, more and more people begin to use computers. Computers are becoming one of the most important parts of our life. There are many arguments for and against the use of computers in everyday life. Some people say that computer make our life more convenient. While others say that they are bad for our health and waste our time. Firstly, Computers make our life easier. People can store a lot of files in the computers, such as documents, photos, even books. This saves our space at home and makes people easy to manage their documents. Also people can buy or know anything they want without going out on the internet through computers. In addition, many computers software benefit us a lot. For example, the Microsoft Word Processer makes you write an article much easier than you write with your hand. Secondly, computers entertain our life in many different ways. There are many entertainments we can do on the computers. Such as playing computer games, chatting with friends, E-mailing others, and so on. These entertainments all enrich our life. However, not all of the uses of computers are positive. Using a computer for a long time will be harmful for our health, especially for our eyes. The radiation of the computer screen hurt our eyes a lot. In addition, computers are bad for the growth of teenagers sometimes. Many teenagers lose themselves in the computer games or the internet. All these affect their daily study and waste their time. Some students play computer games overnight or for several days, this not only affect their study, but also their body health. To sum up, Computers make our life much easier and entertains us in many different ways, but long time use of the computers may affect our health and daily life. So it"s better to control the time of using computers and have a rest after use computer for several hours. .

虽然贝多芬可以很容易的坐下来谱曲，但是他的作曲都来之不易。他往往花费了很大的工夫但是还是不满意自己的曲子。在他28岁的时候他发现耳朵有点变化，而且越来越遭，他便去看医生，得知自己将要耳聋。这是作曲家最怕听到的消息。他绝望了，觉得自己快要死了。他去乡下给他弟弟写了一封很长的遗书。他告诉他渐渐的耳聋带给自己多大的伤心和孤独。他想死，对死神说，“来吧，我回勇敢的迎接你。”事实上他作了比死更勇敢的事情，他骨气勇气，继续作曲。我们所传诵的他谱写的最好的曲子也来自于他耳聋以后。而且不同于他以往的创作。兴奋的音乐使我们记住他的面对困难时勇气。他完全聋的时候，查出了比以往都要好的音乐，虽然听不见，但是他的心里却听的见。他也经常不开心，经常孤单。但是除次而外，他就写音乐。最后交响曲和第九交响曲。因为他的勇气和坚定的意志，他的音乐给无数的人们带来快乐和鼓励

" I am glad to receive your letter. Certainly I am pleased to offer you some advice on learning the English language. It is vital that you do not lose interest easily.Many students find it hard in learning the language, especially in writing good compositions. In my opinion, if you want to improve your writen English, you should learn by heart as much expressions and styles as possible, and then apply them in your compositions. Memorizing the grammar alone is not enough. You must read and write a lot to be an effective learner/writer. To achieve this goal, the most important step you should take is to write every day without giving up."

a year has passed, I will be a student in grade 7. In order to summarize my acdemic achievements, I have made a collection of English compositions. My English teacher told us to read more, write more and listen more. So everytime when I wrote compositions, I was very serious. I believe my level of English would be better and better.手打的哈。。。

A very simple w ay of producing a brine is to take a halite-saturated solution and mix it w ith fresh w ater. The end result w ill be a fluid having a TDS of approximately 150 g / L or so. The ultimate source of chloride，of course，w as the original halite-saturated solution，but the end result of mixing is to produce a much larger volume of hypersaline fluids. This may seem like a trivial w ord game，but it is not. Most fluids in sedimentary basins probably represent blends of various endmembers，and it is likely that the mixing w hich occurs as a result of physical intermingling of fluids as they flow through the complex pore system of a pile of sediments is one of the single most important controls on the salinity and chemical composition of subsurface pore fluids. Waters in direct contact w ith salt are presumably saturated w ith respect to halite and have salinities of 300 g / L or more. As a result of fluid migration and mixing，how ever，a much larger volume of sediment around the dome is filled w ith brine.It is believed that it is more than coincidence that the average salinities of pore fluids in the zone of active halite dissolution in the south Louisiana Gulf Coast are in the range of 125 － 150 g / L. This is roughly a 50∶ 50 mix of halite-saturated brine and fresh w ater. A case can be made for the entire upper few kilometer of this part of the Gulf Coast sedimentary basin being a large and complex mixing zone.While w e are talking about mixing，it w ould be useful to introduce the concepts of conservative and non-conservative behavior during mixing. If during mixing of tw o or more endmember w ater compositions，there are no processes other than physical mixing that affect the concentration of a particular dissolved species， then that species is said to behave in a conservative manner. If，how ever，such processes as precipitation or dissolution or biological uptake also affect the concentration of the dissolved species during mixing，then the species is said to behave in a non-conservative manner. One w ay to test for conservative behavior is to plot the concentration of the species of interest against a know n conservative property of the mixture of solutions. Tw o conservative properties w ill produce a linear plot. Non-linearity can be taken as evidence for non-conservative behavior. Dissolved chloride is often chosen as the conservative reference parameter because in many halite-free environments few processes other than mixing affect its concentration.
