CISM Courses and Lectures Instructions for the Preparation of Manuscripts with L ATEX 2ε

CISM Courses and Lectures:Instructions for the Preparation of Manuscriptswith L A T E X2εAdriano Pascoletti*‡and Carlo Tasso†‡*Department of Mathematics and Computer Science,University of Udine,Udine,Italy †Artiﬁcial Intelligence Laboratory,University of Udine,Udine,Italy‡CISM,International Centre for Mechanical Sciences,Udine,ItalyAbstract This document speciﬁes the formatting requirements forﬁnal manu-scripts that are to be published in the series CISM Courses and Lectures.It alsoexplains how template and styleﬁles can be used.Speciﬁc instructions for theeditor(s)of the volume are also included.1Overview of Manuscript Preparation and DeliveryCISM Lecture Notes are published by SpringerWienNewYork.The preparation of the manuscript is completely based on electronic tools.No paper has to be produced by the authors.The default text processing system to use for preparing the manuscript is L A T E X2ε.When the electronic manuscript is ready,please transform it in PDF format.Re-member to include all the fonts in your PDFﬁle and use only Type1or TrueType fonts.Please avoid the embedding of(resolution-dependent)Type3fonts.If your paper exceeds4MB,please split it into two or moreﬁles,each smaller than4Mb.Authors should send their contributions to the editor(s)of the volume.Editors should collect all the papers and prepare a two-page preface and a table of contents,both according to the templateﬁles available via the CISM web site.Please remember that each contribution should start on a right(recto)page,right pages have odd page numbers,and theﬁrst contribution should start on page1.Transform the preface and the table of contents in PDF format as well.When the whole manuscript is ready,editor(s)should use the CISM ftp server for sending the PDFﬁles to CISM.Please contact Mrs.Monica Del Pin(M.DelPin@cism.it)who will provide you a user-name,a password and the precise URL to use.CISM printing oﬃce will send to the editor(s)a draft version of the cover and of the ﬁrst pages of the volume,to be checked and approved for printing.For further questions about the use of the template and styleﬁles,problems related to PDFﬁles,etc.,you can send an e-mail to the CISM printing oﬃce(ciscud31@nettuno.it).1The templateﬁles wereﬁrst developed for he CISM sponsored conference UM971 (Jameson et al.,1997),further reﬁned for the UM99conference(Kay,1999).Authors who have access to the printed proceedings of UM97or UM99(CISM volumes no.383and407 respectively)can see how the resulting volume is to look.Alternatively,individual UM97 and UM99papers can be downloaded from the on-line proceedings(/). 2Using the Template and Style FilesIn addition to the instructions that you are now reading,templateﬁles for L A T E X2εare available via the CISM Web site.Probably all authors will be able to prepare their manuscripts using one of the templateﬁles.If you can do so,the basic strategy is to copy the templateﬁle and replace the text in it with the text for your own manuscript, using the examples of formatting given in the templateﬁles.3Following the InstructionsSome contributed volumes include individual papers that deviate visibly from the pre-scribed style.In a coherent,well-edited volume,this sort of deviation is not acceptable. In the interests of all authors and readers,the editor(s)will check eachﬁnal manuscript. In order to do this,each author should send a preliminary copy of his/her manuscript to the editor(s).If a manuscript deviates noticeably from the prescribed style,the au-thors will be asked by e-mail or fax to make the necessary adjustments and to resend their manuscript on short notice.If you anticipate any diﬃculties with this arrangement, please contact the editor soon.Font.If you like Times you may use the times package,but only in conjunction with the mathtimes package for typesetting mathematics:mixing Computern Modern Roman fonts for mathematics and Times for text produces unpleasant pages.Running heads.Running heads will be added to each page by the publisher,so please dont add them yourselves except perhaps temporarily for your own convenience during manuscript preparation.Please,use short running heads.Page numbers.The page numbers will be placed in the header by the publisher,nev-ertheless the styleﬁle inserts page numbers—starting from one—centered at the bottom of each page:they may help you and are needed by the publisher.3.1Formatting the Beginning of the ManuscriptTitle,authors,and institutes.Note that each author’s address includes only the institution,the town,the two-letter abbreviation of the state(if the address is in the U.S.),and the country.Note also that acknowledgements to colleagues and funding 1We thank Anthony Jameson from the Department of Computer Science,University of Saarbr¨u cken,Germany,for his eﬀort in preparing the original version of the templateﬁles.2agencies come in a footnote to the authors’names,not in a separate section of the text. Such a footnote is generated by\thanks{...}.As is usual in English,the major words in the title are to be capitalized.Speciﬁcally: Do not capitalize:–conjunctions(and,or,but);–articles(the,a,an);–prepositions of fewer than four letters(like of and for).Do capitalize all other words,including:–words of the above types if they come at the beginning of a heading or after a colon or a dash;–other short words,wherever they come(like Is and Not);–prepositions with four or more letters(like During and With);–words that occur as the second part of a hyphenated compound(as in Real-Time). Abstract.The length of the abstract should not exceed150words.3.2Formatting the Main TextThe package CCLAuthor provides three levels of headings correponding to the usual section,subsection and subsubsection of the article document class.First-level headings.These headings are entered by means of\CCLsection{...}or \CCLsection*{...}for unnumbered headings.Second-level headings.\CCLsubsection{...}places a numbered second-level head-ing,\CCLsubsection*{...}an unnumbered one.Third-level headings.They are entered by means of\CCLsubsubsection{...};the heading at the beginning of this paragraph is an example of this type of heading.There is no numbering and no extra capitalization of major words.The heading ends with punctuation.The subsequent text continues on the same line.3.3Other Formatting ElementsFigures.Figures must be clear and very neat,so we recommend a resolution of600 dpi at least.Center eachﬁgure horizontally,and place the caption after theﬁgure(e.g. see Figure1).Note that there is no extra capitalization of words inﬁgure captions and that each caption ends with a period.Capitalize the word Figure in all in-text references that include numbers(e.g.,“see Figure1”).Example:commands used for inserting Figure1.\begin{figure}[htbp]\centering\includegraphics{samplefig.mps}\caption{A simple...}\label{fCCL} \end{figure}3Figure1.A simple directed graph on three vertices.Tables.Center each table horizontally,and place the caption before the table(e.g.see Table1).Note that there is no extra capitalization of words in table captions and that each caption ends with a period.Capitalize the word Table in all in-text references that include numbers(e.g.,“see Table1”).Table1.Average page length for manuscripts.Category No.of pagesPapers10/lecture(average)Example:commands for Ta-ble1.\begin{table}[htbp]\centering\caption{Average...}\begin{tabular}{|r|l|}\hlineCategory&No.of pages\\\hlinePapers&10/lecture\\&(average)\\\hline\end{tabular}\label{tCCL}Lists.L A T E X2εputs a considerable amount of vertical space between consecutive list items.The CCLAuthor package removes the extra space and produces tighter lists by de-fault.One can get the standard L A T E X2εlist spacing with the command\defaultlists before the list environment.3.4References to LiteratureThe general method used is that of giving the name(s)of the author(s)and the year, using parentheses.The templateﬁle is set up for the plainnat style.Some typical usages are shown below:\citet{CG91}investigated...givesCharniak and Goldman(1991)investigated...4...is well known\citep{CG91}.givesis well known(Charniak and Goldman,1991).\citet[chap.~11]{Fagin:ea95}proved...givesFagin et al.(1995,chap.11)proved...In two influential articles,\citet{Rich79,Rich89}discussed...givesIn two inﬂuential articles,Rich(1979,1989)discussed...A recent study\citep{Fagin:ea95}suggests...givesA recent study(Fagin et al.,1995)suggests...It is claimed\citealp[see][p.2]{Fagin:ea95},and\citealp{CG91})that... givesIt is claimed(see Fagin et al.,1995,p.2,and Charniak and Goldman,1991)that...

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneLike most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving-away makes life so much more exciting. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addresed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. “Wasn’t it you that wrote us that letter a year ago bout delivering a special delivery to your home?” I said it was. “Well, you certainly are going to have a box in this post officeif we have to make one for you. You don’t know what a letter like that means to us. We usually get nothing but complaints.”61. At first the author looked upon life as a process of getting. He formed this view of lifebecause _________A. other people were selfish.B. he thought it exciting to get from others.C. of his early education.D. of his character62. The author wrote a note of appreciation to the post office because _________.A. he knew what such a note would mean to the post officeB. he had discovered giving-away made life more excitingC. he believed he would get something back by doing soD. the postman delivered an important letter in time63. When the author needed a post-office box _________.A. many had applied for post-office boxes before himB. he asked to put his name on a waiting listC. he tried to see the postmasterD. he wrote the postmaster a note of appreciation64. The postmaster promised ________.A. to make a new post-office box for the authorB. to let the author have a post-office boxC. to include the author’s name on the listD. to deliver the author’s mail to his home65. The postmaster interfered because __________A. he overheard their conversation.B. he had received a lot of complaints for lack of boxes.C. he was thankful for the letter the author had written.D. he was proud of their good service.Questions 66 to 70 are based on the following passage:Passage TwoPeople living on parts of the south coast of England face a serious problem. In 1993, the owners of large hotel and several houses discovered, to their horror, that their gardens had disappeared overnight. While experts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea.Erosion of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be abandoned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be swallowed up by the hungry sea.Angry owners have called on the Government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland area of hard rock which will not be eaten as limestone is. Meanwhile, if you want to buy a cheap house with an uncertain future, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for knockdown price but it may turn out to be a knockdown home.66. What is the cause of the problem that people living on parts of the south coast ofEngland face?A. The disappearance of hotels, houses, and gardens.B. The experts’ lack of knowledge.C. The rising of the sea level.D. The washing-away of limestone cliffs.67. The erosion of the white cliffs in the south of England ______.A. will soon become a problem for people living in central EnglandB. has now become a threat to the local residentsC. is quickly changing the map of EnglandD. can be stopped if proper measures are taken68. The experts’ study on the problem of erosion can_________.A. lead to its eventual solutinoB. provide an effective way to slow it downC. help to prevent it from worseningD. warn people whose homes are in danger69. It is not feasible to build sea defenses to protect against erosion because _________.A. it is too costly and will endanger neighbouring areasB. the government is too slow in taking actionC. they will be easily knocked down by waves and currentsD. house agents along the coast do not support the idea.70. According to the author, when buying a house along the south coast of England,people should ________.A. be aware of the potential danger involvedB. guard against being cheated by the house agentC. take the quality of the house into considerationD. examine the house carefully before making a decisionPart IV. Translate following 5 sentences into Chinese ( 5 points)71. A friend of mine named Paul received an automobile from his brother as a Christmaspresent.72. The government has just begun their annual campaign to stop drunken driving.73. In some countries traditional methods of farming have survived to the present day.74. Psychologists often use a method called “behavior therapy” to help individuals solvetheir personality problems.75. In this big department store, staff get 20% discount on all goods during Christmasseasons.Part V.

Lab 2

Lab 2VelocityOverviewIn this lab, we will explore the relationship between the position function and the velocity function of a moving object. In the lectures, we have seen that the velocity function v(t) is the derivative of the position function s(t) (and therefore s(t) is an antiderivative ofv(t)). We will be examining these statements in this lab by using a motion detector to measure the velocity and position of a person walking.Vocabulary used in this lab•Distance: This is the distance an object is from the motion detector. The words distance and position will be used interchangeably in this lab.•Displacement: This is “change of position,” that is, the difference between the initial and terminal coordinates the object. Displacement can be either positive or negative. (Think about what the difference between positive and negativedisplacement is.)•Velocity and speed: The important thing to note here is that velocity can be either positive or negative, depending on whether motion is in the positive ornegative direction. But speed = |v(t)| is never negative: it is the absolute value of the velocity. For example, a car’s speedometer is measuring speed and alwaysreads positive, regardless of the direction you’re traveling.•Total distance traveled: Perhaps this is best illustrated by an example. If you walk 2 meters forward and then 2 meters backward then your displacement willzero (the initial and terminal positions are the same so therefore the difference of coordinates is zero). But, you actually traveled 4 meters. In this case, the totaldistance traveled would be 4 meters. The “total distance traveled” is nevernegative.Mathematics for this labThe mathematics that we will need is the relationship between displacement and velocity: •Displacement is equal to the definite integral of velocity v(t) over a time interval.•Total distance traveled is equal to the definite integral of speed |v(t)|over a time interval.These ideas are discussed in the textbook on pages 374-375.Materials•Computer with Vernier computer interface.•Vernier motion detector. This will plug into the LoggerPro computer interface.•Separate “Lab Report 2” sheet. This is what you will turn in. It is due one week after your scheduled lab day, by 4:30 pm, in the Mathematics Office (Cupples I,room 100).Comments on the Motion DetectorThe motion detector works by emitting short bursts of ultrasonic sound waves. You will hear a clicking sound when the detector is operating. The detector “listens” for the ech o of these ultrasonic waves returning to it. The motion detector measures the time it takes for the sound waves to make the trip from the detector to the object and back to the detector. Knowing the speed of sound, the detector is then able to calculate the distance to the object.The specifications on the detector state that it has a minimum range of 0.4 m. and a maximum range of 6.0 m. The detector seems to work best if there is a smooth flat surface for the sound waves to bounce off of.Practically speaking, this means that as you collect data•Your motion needs to be parallel to the sensor and not perpendicular to it (i.e., you will need to walk either away from or towards the sensor, or both).•You will probably want to be holding a book or piece of cardboard in the sensor’s “line of sight” while you walk.•If neighboring lab teams are moving while you are collecting data, your motion detector might pick up their motion as well. You will have to cooperate with your neighboring teams so that your motion detector is only picking up data from your walking.•It is very important that the motion detector does not move. (What would the motion detector measure if it was moving?)ProcedureThe first thing to do is get the computer and motion detector ready.Connect the motion detector to the Dig/Sonic 2 port of the Lab Pro. Make sure the Lab Pro is connected to the USB port of the computer. (It is likely that these have already been done for you.)•Set the detector upright on the edge of the desk, facing out in a direction in which you have a clear path at least 2 m. long.•Open the LoggerPro program. You will want to select “Lab Pro USB” for the port in the Setup Interface. It is possible (hopefully not likely) that LoggerProwill not recognize the hardware. If this happens, unplugging the Lab Pro andplugging it back in should take care of the problem.•Open the experiment file for this lab. (Click on the “Open” button and open the file labeled “lab2_velocity.” (It is possible that LoggerPro will complain aboutthis file – just ignore any complaint and click “OK.”)•At this point, you should be able to collect distance and velocity data. Try playing around with the motion detector by pressing the “collect button” on thetoolbar. (For example: turn the sensor to face the nearest wall and collect data—what happens? Turn the sensor around and collect data by moving your handback-and-forth in front of it.) When you start collecting data, notice that velocity and distance data is graphed and the actual data appears in a table to the right ofthe graphs. Notice also that each time you start collecting new data, the data from the previous run is cleared. (Another way to clear recently collected data is toselect Data, Delete Run from the menu.)You are now ready to start collecting data that you will analyze.•Decide who will monitor the computer (and hit the collect button) and who will be the “mover”—the mover will create distance and velocity data bywalking back and forth in front of the motion detector.•Your goal is to generate a data set that exhibits both positive and negative velocity during the five seconds of movement.•There is a limited amount of free space in the lab for straight-line movement, so you will have to coordinate your data collection with your neighbors.Make sure you have a clear path before you start collecting your data.•The mover should take an initial position standing in front of the motion detector, holding a book or a piece of cardboard in the detector’s “line ofsight.” This will help to make a smoother velocity graph as you collect thedata.Before beginning, note the mover’s initial position. When the datacollection stops, the mover should remain in position while his/her partnernotes the terminal position. (An acceptable method to note these positionsis to put a marker, like a pen, on the floor where the mover’s feet start.)Measure and write down these positions (number of meters in front of thesensor); you’ll need this information later. (There will be a tape measurein the lab for you to measure the distances. You’re not looking for greataccuracy—just something in the right ballpark. Remember that 1 meter isapproximately 3.28 feet.).•Click on the “Collect” button and gather the data. When the mover hears the motion detector making the clicking sound, s/he should start moving along astraight line in front of the motion detector. Remember your goal to createdata with positive and negative velocity.After collecting your distance and velocity data, you should make sure your data looks “reasonable”: for example,•Is the graph of the velocity reasonably smooth?•Does the distance data in the table look like what you were expecting? Do the distances more-or-less match up with what you noted for the initial and finalpositions?•Is the velocity positive and negative when you were expecting it to be positive and negative?•If your data looks questionable, collect another set of data. (The good news is that it doesn’t take much time to collect another data set if necessary.) •If your data looks good, save it so that you can finish your report after the lab period if necessary. (If you didn’t bring a diskette, you could e-mail the datato yourself.)At this point, you are ready to analyze your data.•You should have two graphs –position (labeled “Distance vs. Time”) and velocity (labeled “Velocity vs. Time). You should print both of these graphs and also the table: activate each graph or table window before you print (so that youget a nice printout of each one separately).•Click on the “Examine” button (Analyze – Examine in the menu). This should allow you to more easily read both the graph and the data (watch what happenswhen you move the mouse to the graphs and the data table). Using this, answer#1-3 on Lab Report 2.DisplacementWe want to calculate the displacement of the mover after 5 seconds. We can do this in three different ways:a) by having LoggerPro estimate the integral of the velocityfunction v(t) for 0 <= t <= 5b) by using our data and the Fundamental Theorem of Calculus (Part II) to evaluate the same integralc) by using the measurements we made “by hand” during the data collection process.In detail:a) Using LoggerPro to estimate the integral of the velocity:•Click on the left-hand side of the velocity graph (Time=0) and drag the black line across to the right-hand side of the graph. While you are doing this, the values in the table window should be highlighted. Make sure you actually click on thegraph on not outside the graph (otherwise you will see the pop-up box asking you about the y-axis and y-scale).•Click the Integral button or choose Analyze – Integrate from the menu. A floating box with LoggerPro’s estimate of the value of the integral appears in the Veloci ty graph window. Note the units in this box: m/s * s, which is just meters (theseconds cancel out); don’t misread the units as “m/sec2” !! Print a copy of thegraph with the box. Record this value in #4a on the Lab Report.b) According the Fundamental Theorem of Calculus (Part II), we can compute the integral of v(t) over the time interval [0,5] using an antiderivative. In this situation, the numeric result can be worked out using subtracting two numbers taken from your data tables. In the Lab Report #4b state what numbers you are using and give the resulting value for the integral.c) Finally, calculate the displacement using the distances from the sensor that you measured during the data collection process. Record the result of the calculation in Lab Report #4c.In Lab Report #4d, you are asked to offer some reasons why the results in a), b) and c) are (probably) not equal.Total Distance TraveledTo find the total distance traveled, we need to integrate the speed |v(t)| during our 5 second time interval. To have LoggerPro do this,we need the speed data—so we create it in a new column:•Activate the velocity graph window by clicking on the velocity graph. Select View – Graph Options from the menu.•Modify the Graph Title by typing “Speed/” before Velocity. It should now read Speed/Velocity vs. Time. Click Apply, then click OK.•Select Data - New Column, Formula from the Data menu. The New Column window will appear.•Under the Options tab, in the Labels section, type “Speed” for Long Name, “sp”for Short Name and “m/s” for Units.•Click the Definition tab. In the Equation box, enter the formula(abs(“Velocity”)). You can (and should) do this by selecting “abs()” from the Functions list followed by selecting “Velocity” from the Variables list.•Click Try New Column. If it new data looks as it should (how should it look?), then click “OK”.•Notice that the new graph (Speed) coincides with the original velocity graph when the velocity is positive. How do these graphs compare when velocity is negative? •Click on the left-hand side of the speed/velocity graph (Time = 0) and drag the black line across to the right-hand side of the graph. All of the values in the table window should be highlighted.•Click the Integrate button. An Integral Selection window appears. Remove the check next to Velocity by clicking in its box. Make sure that Speed is checked.Click OK.• A floating box with LoggerPro’s estimate of the value of the integral appears in the Speed/Velocity graph window. Print a copy of the graph with the box. Report the total distance traveled on Lab Report, #5.Answer #6 and #7 on the Lab Report sheet.。

Received date :2004-04-12.Corresponding author :Prof.WAN G Fengyun.E -mail :wangfywater @yahoo 1com 1cn本文通过连续测定体系电导率的变化,制备了Span 802Tween 80/液体石蜡/AM 2H 2O 体系的反相微乳液,并研究正丁醇、NaCl 和NaAc 对体系的影响,为下一步反相微乳液聚合制备聚丙烯酰胺奠定了基础.1　实验部分111　药品与仪器药品:液体石蜡,Span 80,Tween 80,丙烯酰胺(AM ),正丁醇,氯化钠(NaCl )和乙酸钠(NaAc)均为分析纯;蒸馏水,自制.仪器:磁力搅拌器(7821型),电导仪(DDS2 11型),微量进样器(100μl),超级恒温装置. 112　实验[12]将一定质量比(HLB值)的Span80和Tween80溶解在液体石蜡中,形成油相;按一定浓度将AM溶解在蒸馏水中,形成水相[14].在100ml的烧杯中加入50ml的油相,置于磁力搅拌器中,恒温,搅拌.用微量进样器加入水相,形成反相(W/O型)微乳液.观察体系的导电情况,待体系的电导率稳定后,记录电导率[13,14].2　结果与讨论211　H LB值对反相微乳液体系的影响反相微乳液的稳定性主要依赖于吸附在油相表面上的非离子乳化剂分子的空间位阻效应.用于反相微乳液聚合的乳化剂按照亲水2亲油平衡(HLB)值的原则,一般应选择HLB=3～6.文献表明,将2种乳化剂复配使用的效果要比使用单一乳化剂好[15].本文根据不同Span80和Tween80的质量比配制具有不同HLB值的乳化体系,并研究了HLB值对微乳液形成时电导率的影响,见图1.Fig11　Influence of HLB value on reversemicroemulsion system(Because t here are more data examined,and some data are overlaped,so it is shown as t hicker line in Fig11.A similar phenomenon is shown in Figs12～41) HLB:◆15;■1319;▲1017;×917;●715;+413　由图1可知,随着HLB值的增大,体系增溶同样的水相时,电导率相应增大.当HLB值为715时,体系电导率的变化较小,而且体系的稳定性较好,有利于后续反相微乳液聚合稳定的进行.因此,本文以HLB值为715的微乳液体系作为下一步的研究对象.212　正丁醇对反相微乳液体系的影响图2为正丁醇对微乳液体系的影响.Fig12　Influence of n2butanol onreverse microemulsion systemn2butanol/(mass):◆0;■215;▲510;×10由图2可以看出,随着正丁醇含量的增大,体系的电导率的变化逐渐变小.因为中、长链的醇(如丁醇),也可视为助乳化剂.在2种乳化剂分子交替吸附于微乳液滴的表面上,丁醇的加入相当于在非离子型乳化剂之间又　入了另一种乳化剂分子,因此可以增强微乳液体系的稳定性[16].10% (质量)的正丁醇的电导率几乎没有变化,此时所形成的微乳液体系非常稳定,而且所增溶的水相也比较高,对后续的微乳液聚合而言,可以提高聚合物的固含量.213　电解质对体系的影响Holtzscherer等[17]的研究结果表明,具有盐析效应的电解质可以增加微乳液体系的稳定性.因此本文对NaCl、NaAc在微乳液形成过程中的作用进行了初步探讨.试验结果见图3、图4.Fig13　Influence of NaCl on reversemicroemulsion systemNaCl/%(mass):◆0;■215;▲510;×10由图3、图4可知,对Span802Tween80/液体石蜡/AM2H2O反相微乳液体系而言,加入・963・　第2期王风贺等:Span802Tween80/液体石蜡/AM2H2O反相微乳液体系Fig14　Influence of NaAc on

历史第二讲：儒家文明基督教文明主讲人：刘庆刚新课标老师提醒您：本讲课程概要和讲课思路：因为基本知识点同学平时有所学习，我们不作重点介绍，我们主要讲知识脉络，帮助同学理解和把握历史知识。

而且，由于考纲对伊斯兰教文明不作要求，因此我们本次课程只着重讲述两大文明：儒家文明与基督教文明。

为了使同学们更好地理解儒家文明和基督教文明，本讲以两种文明的起源与发展历程为主线，不仅着眼文明本身的纵向比较，而且着重对它们在政治、法律制度、经济、社会生活等诸多方面进行横向对比，并通过图表的形式再现这两种文明的魅力与特色。

儒家文明区域并非仅仅是指中国，而是指以中国为中心，包括周边国家和地区，其文化也深受儒家文化影响的儒家文化圈。

基督教文明区域以基督教为中心的，包括欧洲为中心的文明区域。

当然，核心是儒家文化和基督教文化，并不排除还有其他文化的存在。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程1、春秋末期，孔子创立儒家学派。

时代背景：春秋末期战国初期，中国正处于社会大变革时期,旧的事物趋近于消亡，新的事物不断兴起，各家思想流派的创始人或思想集大成者，纷纷著书立学说、广招学徒而形成百家争鸣的局面，儒家文化就是在这种百家争鸣的大背景下诞生的。

仁者爱人“仁”统治者实行德政已所不欲，勿施与人一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程1、春秋末期，孔子创立儒家学派。

（1）主要观点：以“仁”作为人们的最高道德准则，以“礼”来规范人们的言行。

（1）主要观点：以“仁”作为人们的最高道德准则，以“礼”来规范人们的言行。

孔子所说的“礼”指的是西周时期形成的一整套等级制度。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程1、春秋末期，孔子创立儒家学派。

（1）主要观点：以“仁”作为人们的最高道德准则，以“礼”来规范人们的言行。

（2）特点：重伦理，重人事，重实践，重教育。

重伦理：君臣之间，臣要对君忠；父子之间，子要对父孝；此外还有夫妻之间；朋友之间；主仆之间等。

重人事：加强个人自身修养，即所谓修身齐家治国平天下。

重实践：学而时习（实践）之。

重教育：开私学；有教无类；学而时习之；因材施教；孟子主张以民为本，施行仁政民为贵，社稷次之，君为轻。

人性本善所以统治者要以民为本，施行仁政人格规范，作为大丈夫的标准：贫贱不能移、威武不能屈、富贵不能淫。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程2、战国时期，孟子和荀子发展了儒家学说。

（1）孟子：儒家的重要代表人物（2）荀子：发展了儒家学说，并提出了新的观点。

荀子主张民心向背是成败的关键同孟子的主张相同人性本恶同孟子的主张相异一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程3、西汉时期，儒家思想开始成为官方哲学。

从西汉时期开始，儒家学说地位提升，逐渐成为封建社会的正统思想、封建文化的主流和核心。

时代背景：西汉初年，社会经济凋敝、国力有限，统治者实行道家无为而治的思想,主张黄老学说。

此后，经过几十年的修养生息政策，至汉武帝时期，经济复苏，国力强盛。

而同时西汉面临内忧（地方王国专权）外患（北方匈奴侵扰），这些因素都迫使最高统治者——汉武帝不得不调整统治政策。

为了实现这种转变必须首先改变统治思想，由“无为”到“有为”。

显然，儒家思想符合这一要求。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程3、西汉时期，儒家思想开始成为官方哲学。

过程：公元前134年，汉武帝下诏书，举贤良，求治国方略。

董仲舒于是在“举贤良对策”中，提出“天人感应、君权神授”的政治主张，渗透“神”的概念，维护了君权的至高无上。

为了实现思想上的大一统，之后他又提出“罢黜百家、独尊儒术”的统治思想，改变了“礼”制的界定，“罢黜百家、独尊儒术”，适应了大一统的趋势，深得汉武帝的赏识和重用。

当然，董仲舒思想与孔子、孟子的思想有很大的不同，比如他把孔子的“礼”改变成适应封建统治者的等级制度，获得封建统治者的认可并大力推行。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程4、宋朝时期理学的形成。

时代背景：三国两晋南北朝时期，宗教开始发展起来，儒家思想作为封建统治者的正统思想遭到冲击而削弱。

●政治上：国家分裂、政权林立，战争频繁、政局动荡；●思想上：道教发展，佛教盛行，宗教的传播大大冲击了儒学的主导地位，遂出现“三教并行”的局面。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程4、宋朝时期理学的形成。

朱熹把宗教的思想加以改造，并融入到儒家思想的体系中，从而形成了理学，南宋朱熹将儒学推向到一个高峰。

新课标为您补充：理学概况：北宋二程（程颢、程颐）兄弟开始创立理学，南宋朱熹集理学大成；理学在南宋后期开始为统治阶级所接受和推崇，经元到明清正式成为国家的统治思想。

朱熹对儒学的发展理是万物之源对理学的界定；存天理灭人欲吸取宗教观念；对四书五经的批注极大弘扬理学。

新课标为您补充：朱熹的格物致知论（知之愈明，则行之愈笃，则知之益明）和美学思想对我们当代也有重要的借鉴意义。

（一）儒家文明的演变历程4、宋朝时期理学的形成。

一、儒家文明和基督教文明的演变历程时代背景：外部原因：西方思想在很多方面都与儒家思想截然相反，也就使得西方思想的进入从外部上洞穿了儒家思想的堡垒。

内部原因：激进的新文化运动发起人提出“打到孔家店”的口号，新文化运动的兴起从内部上摧毁了儒家思想的体系。

（一）儒家文明的演变历程5、新儒学一、儒家文明和基督教文明的演变历程新文化运动——儒学遭到了前所未有的冲击一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程5、新儒学也有很多学者认为儒学有其封建糟粕的东西，也有其精华，需要继承与吸收；于是，他们对儒学进行了改造，比如梁漱溟等人。

这就是儒学发展的第五个阶段——新儒学，也是儒学与现代化的冲突和融合阶段。

新课标为您补充：新中国儒家思想的发展：“文化大革命”时期遭到毁灭性的打击，成为无产阶级专政的对象之一。

新时期改革开放以来，儒家思想地位有所提升，成为进行传统文化和道德教育的主要阵地。

国家领导人出访他国，提出国与国关系“和而不同”，使儒家思想大放异彩，国际上掀起一股学习“儒学”与“孔学”的热潮。

一、儒家文明和基督教文明的演变历程（一）儒家文明的演变历程一、儒家文明和基督教文明的演变历程（二）基督教文明的演变历程1、基督教文明的产生基督教发源于公元1世纪巴勒斯坦地区，创始人为耶稣(Jesus)相传，公元初年，在巴勒斯坦地区，耶稣创立基督教，并在下层民众中传播，他宣扬信仰上帝，主张“爱人如己”。

后因当时罗马帝国的迫害和门徒犹大的告密，被钉在十字架上而死，但其信徒却始终矢志不渝，继续宣扬基督教义并从以色列传向希腊罗马文化区域。

一、儒家文明和基督教文明的演变历程（二）基督教文明的演变历程2、基督教成为国教313年，君士坦丁大帝颁布米兰赦令，基督教成为罗马帝国所允许的宗教；392年，罗马皇帝狄奥多西一世宣布它为国教。

476年，西罗马帝国在外族的入侵下灭亡，而外族在征服过程中却又被西罗马帝国的宗教所征服，比较早皈依基督教的是法兰克王洛维。

以后基督教均被定为“国教”。

一、儒家文明和基督教文明的演变历程（二）基督教文明的演变历程3、基督教的分裂（1）原因：直接原因：东西罗马帝国的分裂，传教教义、礼仪和语言上的差异；根本原因：对教权的争夺。

（2）过程：在1054年，东部教会和西部教会互相宣布把对方宗主教驱逐出教，标志着罗马天主教（以罗马为中心）和东正教（以拜占庭为中心）正式分道扬镳，称为基督教大分裂（第一次分裂）。

一、儒家文明和基督教文明的演变历程（二）基督教文明的演变历程4、基督教的改革（1）背景：（2）导火线（3）表现：鉴于上述背景，15、16世纪，产生出脱离天主教会的不满情绪，成立很多新教教会，如德国的马丁·路德教、瑞士的加尔文教，英国的国教等（总称新教）。

路德提出“因信称义”；1525年，亨利八世自称为英国国教的宗教首领，这些宗教改革被称为是基督教的第二次分裂。

一、儒家文明和基督教文明的演变历程新课标为您总结：儒家文明和基督教文明演变相同点和不同点相同点：很大程度上都走向与政治的融合，得到统治者认同和推行。

不同点：儒家学说与封建统治者没有产生冲突，被改造成适合封建统治的思想工具；而基督教文明与王权的关系紧张，教权与王权互相利用、互相斗争。

二、两种文明在政治上的比较（一）儒家文明在政治上的表现最明显的特征是建立起一整套至上而下的中央集权制度。

中央集权，如果没有任何界定词，这是个中性词，指的是独立统一的政府代表国家，地方听从中央，这样的国家体制都可以称之为中央集权制度，比如现在的中国、美国、法国等；而如果加上界定词，中国封建社会的中央集权，指的是权力集中到皇帝手中，拥有最高决策权。

二、两种文明在政治上的比较（一）儒家文明在政治上的表现最明显的特征是建立起一整套至上而下的中央集权制度，集中表现在以下三个方面：1、中央官制——不断加强皇权2、地方行政——逐渐加强对地方的控制3、选拔人才和官员——加强对臣民思想的控制二、两种文明在政治上的比较（一）儒家文明在政治上的表现1、中央官制的变化——不断加强皇权西周：分封制分封诸侯在其各自的领土上拥有很大权利，诸侯自觉履行对周天子的义务。

权利：周天子将土地分封给诸侯，诸侯是地方最高的行政、司法和军事长官，拥有地方最高权力。

义务：受封诸侯要自觉履行对周天子的义务，比如定期述职，开疆阔土，“勤王”等。

二、两种文明在政治上的比较（一）儒家文明在政治上的表现1、中央官制的变化——不断加强皇权西周：分封制分封诸侯在其各自的领土上拥有很大权利，诸侯自觉履行对周天子的义务。

秦朝：在中央设置三公九卿制丞相：最高行政长官，协助皇帝处理国家政事；御史大夫：监察百官（相当于副相）；太尉：掌管军事三公九卿：指九个具体的行政部门，隶属于丞相管理。

二、两种文明在政治上的比较（一）儒家文明在政治上的表现1、中央官制的变化——不断加强皇权汉朝：汉承秦制，至汉武帝时期开始加强皇权削弱相权隋唐：创立（隋）和完善（唐）了三省六部制，分散和削弱了相权，使中央官制机构之间互为牵制，从而皇权加强。

中书省：负责为皇帝起草政令；门下省：负责审核政令，有权利驳回政令；尚书省：负责执行政令；三省“三省”使得宰相权力一分为三，而三省之间又各司其职、互为牵制，从而大大达到了削弱相权加强皇权的目的。

二、两种文明在政治上的比较（一）儒家文明在政治上的表现1、中央官制的变化——不断加强皇权六部尚书省部：负责官员的考核；部：掌管天下土地、户籍、赋税、财政收支等；部：负责国家典章法制、礼仪、科举、接待外宾等；部：负责武将选用、兵藉军械等各项军政事务；部：负责山川、天地、水利、交通等各项工程；刑部：掌管法律、刑狱事务二、两种文明在政治上的比较（一）儒家文明在政治上的表现1、中央官制的变化——不断加强皇权元朝：中央设置了中书省作为全国的最高行政机构，引领百官，行政首脑丞相直接听命于皇帝。
