Preprint submitted to Acta Phys.Hung.A 22/1(2005)000–000HEA VY ION PHYSICS Hubble-like ?ows in relativistic heavy-ion collisions Mikolaj Chojnacki Institute of Nuclear Physics,Polish Academy of Sciences,31-342Krak′o w,Poland Received 31October 2005Abstract.We study the dynamical appearance of scaling solutions in rela-tivistic hydrodynamics.The phase transition e?ects are included through the temperature dependent sound velocity.If a pre-equilibrium transverse ?ow is included in the initial conditions,then it may reach the form of the asymptotic Hubble ?ow,r/t ,in short evolution times,7-15fm.The numerical solutions are found to support to the freeze-out models (Blast-Wave,Buda-Lund,Cracow).Keywords:ultra-relativistic heavy-ion collisions,relativistic hydrodynamics PACS:25.75.Dw,21.65.+f,14.40.-n 1.Introduction This article is a contribution to the Quark Matter 2005poster proceedings,prepared with W.Florkowski and T.Cs¨o rg?o ,and based on our recent paper [1].The successful parameterizations [2,3,4]of the freeze-out process at RHIC indicate that the system formed in Au+Au collisions is highly thermalized and exhibits strong longitudinal and transverse expansion that may be characterized by the Hubble law,v =H r .Such form of expansion is used in cosmology,with H
being a function of time (in spite of the time dependence,H is commonly called the Hubble constant).The analogy between the Hubble law used in cosmology and in relativistic hydrodynamics is related to the dependence of the four-velocity u μon the space-time position of the ?uid element x μ,
u μ=x μτ 1,x t ,

?x 2?y 2?z 2is the invariant time.The form of the four-velocity displayed by Eq.(1)is known as the scaling solution .In many cases it represents the asymptotic solution of the hydrodynamic equations [5,6,7].In our approach we assume that the elementary parton-parton collisions that lead to thermalization of the system also lead to collective behavior,i.e.,to the development of the pre-equilibrium transverse ?ow.This type of the ?ow has to be included in the initial

In our numerical calculations we consider two forms of the sound velocity.The?rst one is obtained from the QCD lattice calculations[9]and extrapolated to lower temperatures,while the second one is the analytic parameterization of these points. The latter form allowed us to calculate functionsΦT and TΦanalytically.
2.2.Initial conditions
We use the same method for constructing initial conditions as in[8],i.e.,a single function a(r)is used to determine the initial forms of the functions a+and a?, namely a+(t=t0,r)=a(r),a?(t=t0,r)=a(?r).Such procedure insures that a cylindrically symmetrical system has vanishing velocity?eld at r=0.In addition, we assume that the initial temperature pro?le is connected with the thickness func-tion T A(r).We assume that the initially produced entropy density is proportional to the number of nucleons participating in the collision at the distance r from the collision center,σ(r)～T A(r),and at high temperature our system may be consid-ered as a system of massless particles.Since the entropy density of a massless gas is proportional to T3we?nd

《剑桥小学英语Join In ——Book 3 下学期》教材教法分析2012-03-12 18:50:43| 分类：JOIN IN 教案| 标签：|字号大中小订阅. 一、学情分析： 作为毕业班的学生，六年级的孩子在英语学习上具有非常显著的特点： 1、因为教材的编排体系和课时不足，某些知识学生已遗忘，知识回生的现象很突出。 2、有的学生因受学习习惯及学习能力的制约，有些知识掌握较差，学生学习个体的差异性，学习情况参差不齐、两级分化的情况明显，对英语感兴趣的孩子很喜欢英语，不喜欢英语的孩子很难学进去了。 3、六年级的孩子已经进入青春前期，他们跟三、四、五年级的孩子相比已经有了很大的不同。他们自尊心强，好胜心强，集体荣誉感也强，有自己的评判标准和思想，对知识的学习趋于理性化，更有自主学习的欲望和探索的要求。 六年级学生在英语学习上的两极分化已经给教师的教学带来很大的挑战，在教学中教师要注意引导学生调整学习方式： 1、注重培养学生自主学习的态度 如何抓住学习课堂上的学习注意力，吸引他们的视线，保持他们高涨的学习激情，注重过程的趣味化和学习内容的简易化。 2、给予学生独立思考的空间。 3、鼓励学生坚持课前预习、课后复习的好习惯。 六年级教材中的单词、句子量比较多，难点也比较多，学生课前回家预习，不懂的地方查英汉词典或者其它资料，上课可以达到事半功倍的效果，课后复习也可以很好的消化课堂上的内容。 4、注意培养学生合作学习的习惯。 5、重在培养学生探究的能力：学习内容以问题的方式呈现、留给学生更多的发展空间。 二、教材分析： （一）.教材特点： 1．以学生为主体，全面提高学生的素质。
