介词语法问题More and more people live in towns instead of on farms?

第一个因为三者搭配的介词不都相同,三个名词得分别用不同的介词来连接所以不可省略: 【in】 town 【on】farm 【in】 village 而如果要是town和village搁在一起,把这三个词调一下个可就不一样了.由于town和village的介词相同,所以可用同一个in来连接: More and more people live on farms instead of in towns and(in)villages. 第二个两者搭配的介词相同所以可以省略: 【in】 a classroom 【in】 a department store classroom和department store可以用相同的介词in,所以就省略成了: How to act in a classroom,or (in) a department store? 而如果后者不是a department store 而是farm,那就不一样了: How to act in a classroom,or on a farm? 我是认真回答的.希望能对你有所帮助.,10,应该是因为第一句中的三个名词用不同的介词才可以 town , farm, village, 而第二句中的classroom, department store可以用相同的介词in 所以就省略了的原因吧。,1,第一个因为两者搭配的介词不同 所以不可省略 第二个两者搭配的介词相同所以可省 加上去也是对的,1,这是因为英语中与不同名词连用时要用不同的介词 in a town, in towns (cities) on a farm, on farms 这个比较特殊 in villages in a classroom, in a department store前面已经有了同样的in,英语中同样要避免不必要的重复,所以这里只用一个,0,介词语法问题 More and more people live in towns instead of on farms and in villages. How to act in a classroom,or a department store? 都是有两个介词词组,为什么第一句中ON 和IN都要,而第二句中就只用了一个IN呢?

高考英语阅读理解训练附答案

2017高考英语阅读理解训练附答案   2017高考英语改革后实行一年两考,可多次参加,我认为对自己有信心的.同学可以早点参加,取得理想的成绩后就可以把学习重心放到其他科目上。为了帮助大家备考,我整理了一些高考英语阅读理解,希望能帮到大家!   history   If we were asked exactly what we were doing a year ago,we should probably have to say that we could not remember But if we had kept a book and had written in it an account of what we did each day,we should be able to give an answer to the question.   It is the same in history Many things have been forgotten because we do not have any written account of them Sometimes men did keep a record of the most important happenings in their country,but often it was destroyed by fire or in a war.Sometimes there was never any written record at all because the people of that time and place did not know how to Write.For example,we know a good deal about the people who lived in China 4,000 years ago, because they could write and leave written records for those who lived after them.But we know almost nothing about the people who lived even 200 years ago in central Africa. because they had not learned to write. Sometimes.of course,even if the people cannot write,they may know something of the past.They have heard about it from older people,and often songs and dances and stories have been made about the most important happenings,and these have been sung and acted and told for many generations For most people are proud to tell what their fathers did in the past.This we may call u201fremembered historyu2019.Some of it has now been written down. It is not so exact or so valuable to us as written history is,because words are much more easily changed when used again and again in speech than when copied in writing.But where there are no written records,such spoken stories are often very helpful.   41. Which of the following ideas is not suggested in the passage?   A.“Remembered history”,compared with written history,is less reliable   B.Written records of the past play the most important role in our learning of the human history.   C.A written account of our daily activities helps US to be able to answer many questions.   D.Where there are no written records.there is no history.   42.We know very little about the central Africa 200 years ago because   A.there was nothing worth being written down at that time   B .the people there ignored the importance of keeping a record   C.the written records were perhaps destroyed by a fire   D.the people there did not know how to write   43.“Remembered history”refers to   A.history based on a personu201fs imagination   B .stories of important happenings passed down from mouth to mouth   C .songs and dances about the most important events   D .both B and C   44.“Remembered history”is regarded as valuable only when   A. it is written down   B .no written account is available   C.it proves to be time   D.people are interested in it   45 .The passage suggests that we could have learned much more about our past than we do now if the ancient people had   A.kept a written record of every past event   B. not burnt their written records in wars   C.told exact stories of the most important happenings   D.made more songs and dances   答案:DDDBA   land produces   Although the United States covers so much land and the land produces far more food than the present population needs,its people are by now almost entirely an urban society Less than a tenth of the people are engaged in agriculture and forestry(林业),and most of the rest live in or around towns,small and large.Here the traditional picture is changing:every small town may still be very like other small towns,and the typical small town may represent a widely accepted view of the country,but most Americans do not live in small towns any more.Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs、of more than a million people each—a larger proportion than in Germany or England,let alone France.The statistics(统计)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day.As the rush to live out of town continues.rural areas within reach of towns are gradually filled with houses,so that it is hard to say at what moment a piece of country becomes a suburb But more and more the typical American lives in a metropolitan rather than a small town environment.   36.If now America has 250 million people.how many of them are engaged in agriculture and forestry?   A.About 25 million.   B.More than 25 million.   C.Less than 25 million.   D. Less than 225 million   37.Which of the following four countries has the smallest proportion of people living in metropolitan areas?   A.United States.   B.Germany.   C.France.   D.England.   38.Whatu2019s the meaning of the word“metropolitan”in the middle of the passage?   A .Of a large city with its suburbs.   B.Of small and large towns.   C.Of urban areas.   D.Of rural areas.   39.According to the passage,what can we learn about small towns in the United States?   A Most small towns become gradually crowded   B.Small towns are still similar to each other.   C.As the traditional picture is changing,towns are different.   D .Small towns are turning into large cities   40.Why is it hard to say when a piece of country becomes a suburb?   A.Because they are the same.   B.Because the rush takes place too quickly   C.Because the process is gradual.   D.Because more and more Americans live in metropolitan   答案:CCABC   president   There are stories about two U.S . presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK.We donu201ft know if either story is true,but they are both interesting. The first explanation is based on the fact that President Jackson had very little education.In fact,he had difficulty reading and writing.When important papers came to Jackson,he tried to read them and then had his assistants explain what they said.If he approved of a paper.he would write“all correct”on it.The problem was that he didnu201ft know how to spell.So what he really wrote was“ol korekt”.After a while,he shortened that term to“OK”.   The second explanation is based on the place where President Van Buren was born,Kinderhook,New York.Van Bnrenu201fs friends organized a club to help him become President They caned the club the Old Kinderhook Club,and anyone who supported Van Buren was called“OK”.   31.The author   A. believes both of the stories   B.doesnu201ft believe a word of the stories   C is not sure whether the stories are true   D. is telling the stories just for fun   32. According to the passage,President Jackson   A.couldnu201ft draw up any documents at all   B. didnu201ft like to read important papers by himself   C.often had his assistants sign documents for him   D .wasnu201ft good at reading,writing or spelling   33.According to the first story, the term “OK”   A. was approved of by President Jackson   B.was the title of some Official documents   C.was first used by President Jackson   D.was an old way to spell“all correctu2019u2019   34 .According to the second story,the termu2018u2018OK”   A.was the short way to sayu2018u2018old Kinderhook Club”   B.meant the place where President Van Buren was born   C.was the name of Van Burenu201fs club   D.was used to call Van Burenu201fs supporters in the election   35.According to the second story.the term“OK”was first used   A.by Van Buren   B.in a presidential election   C.to organize the Old Kinderhook Club   D.by the members of theu2018u2018Old Kinderhook Club”   答案:CDCDB ;

武汉的英文介绍

Wuhan, composed of the three towns of Wuchang, Hankou, and Hanyang, is the capital of Hubei Province. The three towns, separated by the Yangtze and Hanshui rivers,a re linked by bridges, and because these municipalities are so closely connected by waterways, Wuhan is also called the "city on rivers." Being the largest inland port on the middle reaches of the Yangtze River and a major stop on the Beijing-Guangzhou Railway, Wuhan is one of China‘s most important hubs of water and rail transportation and communications. Wuhan has an old history and rich cultural traditions. It began to prosper as a commercial town about two thousand years ago, when it was called Yingwuzhou (Parrot beach). From the first century to the beginning of the third century, the towns of Hanyang and Wuchang began to take shape. During the Song Dynasty (960-1279), the area became one of the most prosperous commercial centers along the Yangtze River. By the end of the Ming Dynasty (1368-1644), Hankou had become one of the four most famous cities in China. Today, Wuhan is the political, economic, and cultural center of Central China. It boasts of one of China‘s leading iron and steel complexes -- the Wuhan Iron and Steel Corporation. Wuhan is also a city with a strong revolutionary tradition. 武汉,是由三个城镇的武昌,汉口,汉阳组成,武汉是湖北省的省会。这三个城镇,长江和汉水的河流将三镇分开,并用桥梁连接起来,因为这些城市四处环湖,所以武汉也被称为“湖中之城。 ”作为世界上最大的内陆港口上中游和长江流域主要的京广铁路在此通过,武汉是中国最重要的枢纽供水和铁路运输和通讯等方面。 武汉有悠久历史和丰富的文化传统。它开始作为一个繁荣的商业城约二千年前,当它被称为Yingwuzhou (鹦鹉海滩) 。武汉最开始由汉阳和武昌区组成。在宋代( 960-1279 ) ,成为该地区最繁荣的商业中心,沿长江。到了明代( 1368年至1644年) ,汉口已成为中国4大城市之一。今天,武汉是中国政治,经济,文化中心。武汉拥有全国优秀钢铁企业-武汉钢铁公司。武汉也是一个革命传统的城市。

The three towns, separated by the Yangtze and Hanshui rivers,a re linked by bridges, and because these municipalities are so closely connected by waterways, Wuhan is also called the "city on rivers." Being the largest inland port on the middle reaches of the Yangtze River and a major stop on the Beijing-Guangzhou Railway, Wuhan is one of China‘s most important hubs of water and rail transportation and communications. Wuhan has an old history and rich cultural traditions. It began to prosper as a commercial town about two thousand years ago, when it was called Yingwuzhou (Parrot beach). From the first century to the beginning of the third century, the towns of Hanyang and Wuchang began to take shape. During the Song Dynasty (960-1279), the area became one of the most prosperous commercial centers along the Yangtze River. By the end of the Ming Dynasty (1368-1644), Hankou had become one of the four most famous cities in China. Today, Wuhan is the political, economic, and cultural center of Central China. It boasts of one of China‘s leading iron and steel complexes -- the Wuhan Iron and Steel Corporation. Wuhan is also a city with a strong revolutionary tradition.

openGL 是什么软件

OpenGL三维图形标准是由AT&T公司UNIX软件实验室、IBM 、DEC、SUN、HP、Microsoft和SGI等多家公司在GL图形库标准的基础 上联合推出的开放式图形库,它使在微机上实现三维真实 感图形的生成与显示成为可能。由于OpenGL是开放的图形标 准,用户原先在UNIX下开发的OpenGL图形软件很容易移植到微 机上的WindowsNT/95上。笔者在VisualC++4.1(以下简称VC)集 成环境下,开发了基于OpenGL的三维真实感图形应用程序,现 介绍如下。 微机上的OpenGL开发环境 基于OpenGL标准开发的应用程序必须运行于32位Windows 平台下,如WindowsNT或Windows95环境;而且运行时还需有动态 链接库OpenGL32.DLL、Glu32.DLL,这两个文件在安装WindowsNT时已 自动装载到C:WINNTSYSTEM32目录下(这里假定用户将WindowsNT 安装在C盘上);而对于使用Windows95平台的用户,则需手工将 两个动态库复制到Windows95目录的SYSTEM子目录中。安装了 WindowsNT/95和VC4.1后,用户就具备了基于OpenGL开发三维图 形软件的基本条件。 OpenGL程序设计的基本步骤 1.OpenGL在WindowsNT下的运行机制 OpenGL工作在客户机/服务器模式下,当客户方(即基 于OpenGL标准开发的应用程序)向服务器(OpenGL核心机制)发出 命令时,由服务器负责解释这些命令。通常情况下,客户方 和服务器是运行在同一台微机上的。由于OpenGL的运行机制 是客户机/服务器模式,这使得用户能够十分方便地在网 络环境下使用OpenGL,OpenGL在WindowsNT上的这种实现方式通常 称为网络透明性。 OpenGL的图形库函数封装在动态链接库OpenGL32.DLL中, 客户机中的所有OpenGL函数调用,都被传送到服务器上,由 WinSrv.DLL实现功能,再将经过处理的指令发送到Win32设备驱 动接口(DDI),从而实现在计算机屏幕上产生图像。 若使用OpenGL图形加速卡,则上述机制中将添加两个 驱动器:OpenGL可装载客户模块(OpenGLICD)将安装在客户端;硬 件指定DDI将安装在服务器端,与WinDDI同一级别。 2.OpenGL的库函数 开发基于OpenGL的应用程序,必须先了解OpenGL的库函 数。OpenGL函数命令方式十分有规律,每个库函数均有前缀gl 、glu、aux,分别表示该函数属于OpenGL基本库、实用库或辅助 库。WindowsNT下的OpenGL包含了100多个核心函数,均以gl作为前 缀,同时还支持另外四类函数: OpenGL实用库函数:43个,以glu作为前缀; OpenGL辅助库函数:31个,以aux作为前缀; Windows专用库函数(WGL):6个,以wgl作为前缀; Win32API函数(WGL):5个,无前缀。 OpenGL的115个核心函数提供了最基本的功能,可以实 现三维建模、建立光照模型、反走样、纹理映射等;OpenGL实 用库函数在核心函数的上一层,这类函数提供了简单的调 用方法,其实质是调用核心函数,目的是减轻开发者的编程 工作量;OpenGL辅助库函数是一些特殊的函数,可以供初学者 熟悉OpenGL的编程机制,然而使用辅助库函数的应用程序只 能在Win32环境中使用,可移植性较差,所以开发者应尽量避 免使用辅助库函数;Windows专用库函数(WGL)主要针对WindowsNT /95环境的OpenGL函数调用;Win32API函数用于处理像素存储格 式、双缓存等函数调用。 3.VC环境下基于OpenGL的编程步骤 下面介绍在VC环境中建立基于Opeetting菜单选项,在Link栏的Lib输入域中 添加openg132.lib、glu32.lib,若需使用OpenGL的辅助库函数,则还 需添加glaux.lib。 (3)选择View/ClassWizard菜单选项,打开MFC对话框,在 ClassName栏中选择CMyTestView类,进行以下操作: 选择WM_CREATE消息,鼠标单击EditCode,将OpenGL初始化代码 添加到OnCreate()函数中: /*定义像素存储格式*/ PIXELFORMATDESCRIPTORpfd= { sizeof(PIXELFORMATDESCRIPTOR), 1, PFD_DRAW_TO_WINDOW|PFD_SUPPORT_OPENGL, PFD_TYPE_RGBA, 24, 0,0,0,0,0,0, 0,0,0,0,0,0,0 32, 0,0, PFD_MAIN_PLANE, 0, 0,0,0, } CCLientdc(this); intpixelFormat=ChoosePixelFormat(dc.m_hDC,&pfd); BOOLsuccess=SetPixelFormat(dc.m_hDC,pixelFormat,&pfd); m_hRC=wglCreateContext(dc.m_hDC); 选择WM_DESTORY消息,在OnDestory()中添加以下代码: wglDeleteContext(m_hRC); 在MyTestView.cpp中,将以下代码添加到PreCreateWindows()函数中: cs.style|=WS_CLIPCHILDREN|WS_CLIPSIBLINGS; OpenGL只对WS_CLIPCHILDREN|WS_CLIPSIBLINGS类型窗口有效; 在MyTestView.cpp中,将以下代码添加到OnDraw()函数中: wglMakeCurrent(pDC->m_hDC,m_hRC); DrawScene();//用户自定义函数,用于绘制三维场景; wglMakeCurrent(pDC->m_hDC,NULL); 在MyTestView.cpp中,添加成员函数DrawScene(): voidCMyTestView::DrawScene() {/*绘制三维场景*/} (4)在MyTestView.h中包含以下头文件并添加类成员说明: #include #include #include 在CTestView类中的protected:段中添加成员变量声明: HGLRCm_hRC; 同时添加成员函数声明: DrawScene(); 这样,一个基于OpenGL标准的程序框架已经构造好,用 户只需在DrawScene()函数中添加程序代码即可。 建立三维实体模型 三维实体建模是整个图形学的基础,要生成高逼真 度的图像,首先要生成高质量的三维实体模型。 OpenGL中提供了十几个生成三维实体模型的辅助库函 数,这些函数均以aux作为函数名的前缀。简单的模型,如球 体、立方体、圆柱等可以使用这些辅助函数来实现,如 auxWireSphere(GLdoubleradius)(绘制一半径为radius的网状球体)。 但是这些函数难以满足建立复杂三维实体的需要,所以用 户可以通过其它建模工具(如3DS等)来辅助建立三维实体模 型数据库。笔者在三维实体的建模过程中采用3DS提供的2D Shape、3DLofter和3DEditor进行模型的编辑,最后通过将模型数 据以DXF文件格式输出存储供应用程序使用。 真实感图形的绘制 1.定义光照模型和材质 (1)光源。OpenGL提供了一系列建立光照模型的库函 数,使用户可以十分方便地在三维场景中建立所需的光照 模型。OpenGL中的光照模型由环境光(AmbientLight)、漫射光 (DiffuseLight)、镜面反射光(SpecularLight)等组成,同时还可设 置光线衰减因子来模拟真实的光源效果。 例如,定义一个黄色光源如下: GlfloatLight_position[]={1.0,1.0,1.0,0.0,}; GlfloatLight_diffuse[]={1.0,1.0,0.0,1.0,}; glLightfv(GL_LIGHT0,GL_POSTTION,light_position);//定义光源位置 glLightfv(GL_LIGHT0,GL_DIFFUSE,light_diffuse);//定义光源漫射光 光源必须经过启动后才会影响三维场景中的实体,可以通过以下指令使光源有效:< glEnable(LIGHTING);//启动光照模型; glEnable(GL_LIGHT0);//使光源GL_LIGHT0有效; OpenGL中一共可以定义GL_LIGHT0~GL_LIGHT7八个光源。 (2)材质。OpenGL中的材质是指构成三维实体的材料在 光照模型中对于红、绿、蓝三原色的反射率。与光源的定义 类似,材质的定义分为环境、漫射、镜面反射成分,另外还 有镜面高光指数、辐射成分等。通过对三维实体的材质定义 可以大大提高应用程序所绘制的三维场景的逼真程度。例 如: /*设置材质的反射成分*/ GLfloatmat_ambient[]={0.8,0.8,0.8,1.0}; GLfloatmat_diffuse[]={0.8,0.0,0.8,1.0};/*紫色*/ GLfloatmat_specular[]={1.0,0.0,1.0,1.0};/*镜面高光亮紫色*/ GLfloatmat_shiness[]={100.0};/*高光指数*/ glMaterialfv(GL_FRONT,GL_AMBIENT,mat_ambient);/*定义环境光反射率*/ glMaterialfv(GL_FRONT,GL_DIFFUSE,mat_diffuse);/*定义漫射光反射率*/ glMaterialfv(GL_FRONT,GL_SPECULAR,mat_specular);/*定义镜面光反射率*/ glMaterialfv(GL_FRONT,GL_SHINESS,mat_shiness);/*定义高光指数*/ (3)材质RGB值与光源RGB值的关系。OpenGL中材质的颜色 与光照模型中光源的颜色含义略有不同。对于光源,R、G、B 值表示三原色在光源中所占有的比率;而对于材质定义,R、 G、B的值表示具有这种材质属性的物体对于三原色的反射 比率,场景中物体所呈现的颜色与光照模型、材质定义都相 关。例如,若定义的光源颜色是(Lr,Lg,Lb)=(1.0,1.0,1.0)(白光), 物体的材质颜色定义为(Mr,Mg,Mb)=(0.0,0.0,0.8),则最终到达人 眼的物体颜色应当是(Lr*Mr,Lg*Mg,Lb*Mb)=(0.0,0.0,0.8)(蓝色)。 2.读取三维模型数据 为了绘制三维实体,我们首先必须将预先生成的三 维实体模型从三维实体模型库中读出。下图描述了读取三 维实体模型的流程。 3.三维实体绘制 由于3DS的DXF文件中对于三维实体的描述是采用三角 形面片逼近的方法,而在OpenGL函数库中,提供了绘制三角形 面片的方法,所以为三维实体的绘制提供了方便。以下提供 了绘制三角形面片的方法: glBegin(TRANGLES);//定义三角形绘制开始 glVertexf((GLfloat)x1,(GLfloat)y1,(GLfloat)z1);//第一个顶点 glVertexf((GLfloat)x2,(GLfloat)y2,(GLfloat)z2);//第二个顶点 glVertexf((GLfloat)x3,(GLfloat)y3,(GLfloat)z3);//第三个顶点 glEnd();//绘制结束 为了提高三维实时动画的显示速度,我们利用了 OpenGL库中的显示列表(DisplayList)的功能,将三维场景中的实 体分别定义为单独的显示列表,预先生成三维实体。在图形 显示时,只需调用所需的显示列表即可显示相应的三维实 体,而不需要重新计算实体在场景中的坐标,避免了大量的 浮点运算。在调用显示列表前所作的旋转、平移、光照、材 质的设定都将影响显示列表中的三维实体的显示效果。具 体实现算法如下: for(ObjectNo=0;ObjectNo<实体个数;ObjectNo++) { glNewList(ObjectNo,GL_COMPILE);//创建第ObjectNo个实体的显示列表 for(Fac

如何设置魔兽争霸opengl模式

在你的桌面上的魔兽快捷方式上单击右键,选属性,进入属性单击快捷方式选项卡,在目标一栏的配置符最后加" -opengl"(不包括引号),注意在"-"之前一定要加上一个英文状态下的空格,不然是连游戏也进不去的。最后点应用,确定.在桌面上刷新两次进游戏。扩展资料:高级功能OpenGL被设计为只有输出的,所以它只提供渲染功能。核心API没有窗口系统、音频、打印、键盘/鼠标或其它输入设备的概念。虽然这一开始看起来像是一种限制,但它允许进行渲染的代码完全独立于他运行的操作系统,允许跨平台开发。然而,有些整合于原生窗口系统的东西需要允许和宿主系统交互。这通过下列附加API实现:GLX - X11(包括透明的网络)WGL - Microsoft WindowsAGL - Apple MacOS另外,GLUT库能够以可移植的方式提供基本的窗口功能。参考资料:OpenGL—百度百科

核外电子的排布规律

1、基本规律  1、泡利不相容原理:每个轨道最多只能容纳两个电子,且自旋相反配对  2、能量最低原理:电子尽可能占据能量最低的轨道  3、Hund规则:简并轨道(能级相同的轨道)只有被电子逐一自旋平行地占据后,才能容纳第二个电子  另外:等价轨道在全充满、半充满或全空的状态是比较稳定的,亦即下列电子结构是比较稳定的:  全充满---p6或d10 或f14  半充满----p3或d5或f7  全空-----p0 或d0或 f0  还有少数元素(如某些原子序数较大的过渡元素和镧系、锕系中的某些元素)的电子排布更为复杂,既不符合鲍林能级图的排布顺序,也不符合全充满、半充满及全空的规律。而这些元素的核外电子排布是由光谱实验结构得出的,我们应该尊重光谱实验事实。  对于核外电子排布规律,只要掌握一般的规律,注意少数例外即可。  处于稳定状态的原子,核外电子将尽可能地按能量最低原理排布,另外,由于电子不可能都挤在一起,它们还要遵守保里不相容原理和洪特规则,一般而言,在这三条规则的指导下,可以推导出元素原子的核外电子排布情况,在中学阶段要求的前36号元素里,没有例外的情况发生。2、最低能量原理  电子在原子核外排布时,要尽可能使电子的能量最低。怎样才能使电子的能量最低呢?比方说,我们站在地面上,不会觉得有什么危险;如果我们站在20层楼的顶上,再往下看时我们心理感到害怕。这是因为物体在越高处具有的势能越高,物体总有从高处往低处的一种趋势,就像自由落体一样,我们从来没有见过物体会自动从地面上升到空中,物体要从地面到空中,必须要有外加力的作用。电子本身就是一种物质,也具有同样的性质,即它在一般情况下总想处于一种较为安全(或稳定)的一种状态(基态),也就是能量最低时的状态。当有外加作用时,电子也是可以吸收能量到能量较高的状态(激发态),但是它总有时时刻刻想回到基态的趋势。一般来说,离核较近的电子具有较低的能量,随着电子层数的增加,电子的能量越来越大;同一层中,各亚层的能量是按s、p、d、f的次序增高的。这两种作用的总结果可以得出电子在原子核外排布时遵守下列次序:1s、2s、2p、3s、3p、3d、4s、4p……3、最低能量原理  电子在原子核外排布时,要尽可能使电子的能量最低。怎样才能使电子的能量最低呢?比方说,我们站在地面上,不会觉得有什么危险;如果我们站在20层楼的顶上,再往下看时我们心理感到害怕。这是因为物体在越高处具有的势能越高,物体总有从高处往低处的一种趋势,就像自由落体一样,我们从来没有见过物体会自动从地面上升到空中,物体要从地面到空中,必须要有外加力的作用。电子本身就是一种物质,也具有同样的性质,即它在一般情况下总想处于一种较为安全(或稳定)的一种状态(基态),也就是能量最低时的状态。当有外加作用时,电子也是可以吸收能量到能量较高的状态(激发态),但是它总有时时刻刻想回到基态的趋势。一般来说,离核较近的电子具有较低的能量,随着电子层数的增加,电子的能量越来越大;同一层中,各亚层的能量是按s、p、d、f的次序增高的。这两种作用的总结果可以得出电子在原子核外排布时遵守下列次序:1s、2s、2p、3s、3p、3d、4s、4p……4、洪特规则  从光谱实验结果总结出来的洪特规则有两方面的含义:一是电子在原子核外排布时,将尽可能分占不同的轨道,且自旋平行;洪特规则的第二个含义是对于同一个电子亚层,当电子排布处于  全满(s2、p6、d10、f14)  半满(s1、p3、d5、f7)  全空(s0、p0、d0、f0)时比较稳定。这类似于我们坐电梯的情况中,要么电梯是空的,要么电梯里都有一个人,要么电梯里都挤满了两个人,大家都觉得比较均等,谁也不抱怨谁;如果有的电梯里挤满了两个人,而有的电梯里只有一个人,或有的电梯里有一个人,而有的电梯里没有人,则必然有人产生抱怨情绪,我们称之为不稳定状态。  例如,第24号元素铬Cr,如果按照各能级填充规则,其核外电子排布式应为1s22s22p63s23p63d44s2 但是,依据洪特规则可知3d能级填充5个电子时较稳定,所以其核外电子排布式为1s22s22p63s23p63d54s1  同理,第29号元素铜Cu的核外电子排布式应为1s22s22p63s23p63d104s1。5、核外电子排布的方法  对于某元素原子的核外电子排布情况,先确定该原子的核外电子数(即原子序数、质子数、核电荷数),如24号元素铬,其原子核外总共有24个电子,然后将这24个电子从能量最低的1s亚层依次往能量较高的亚层上排布,只有前面的亚层填满后,才去填充后面的亚层,每一个亚层上最多能够排布的电子数为:s亚层2个,p亚层6个,d亚层10个,f亚层14个。最外层电子到底怎样排布,还要参考洪特规则,如24号元素铬的24个核外电子依次排列为  1s22s22p63s23p64s23d4  根据洪特规则,d亚层处于半充满时较为稳定,故其排布式应为:  1s22s22p63s23p64s13d5  最后,按照人们的习惯“每一个电子层不分隔开来”,改写成  1s22s22p63s23p63d54s1  即可。

化学,SnCl2中,Sn的外层电子为啥有六个电子就足够了?为啥各个Cl不能额外再给Sn一个电子?

化学元素的活泼性,是指元素与其他物质反应的难易程度。越易和别的物质反应,元素越活泼。越难与其他物质反应,元素越不活泼,即越稳定。 氮气不如氧气活泼,这是单质(或者说是分子)的活泼性,而不是元素的活泼性。化学中要注意区分这些概念。因为,元素活泼性和分子活泼性的成因是完全不同的。 对于氮气和氧气,氮气的活泼型低于氧气的活泼性,本质是每个氮气分子中有三个氮氮键,加起来键能很高,所以氮分子中的氮原子结合得很牢固,其间的化学键不易断裂,导致不易发生原子重组(化学反应是原子重新组合的过程),所以不易反应,活泼性低。而氧分子中只有两个氧氧键,加起来键能比较低,所以易反应。当然,这也与氧元素的易得电子的性质有关联。但是,分子的活泼性,主要是看键能大小。(到了大学,也可以用分子轨道理论来解释,通过比较键级,从而比较分子的稳定性) 对于元素的活泼性,我们就主要考虑元素原子的最外层电子的排布情况。在这里,我也曾有过误区,现在明白了。原子最外层电子数不超过八(除第一周期外),最外层电子少于四(尤其是只有一个或两个电子时),易失电子,活泼;最外层电子大于四(尤其是有六个或七个电子),易得电子,同样活泼;而最外层电子为四或接近四时,不易得失电子,不活泼;最外层电子为八(第一周期,最外层电子为2)的元素,最稳定,组成惰性气体一族,因为不易一下失掉八个电子,也不易再得电子(因为得的电子填充到下一层,整体能量将增高,而物质要稳定是趋向于能量最低的状态,即能量最低原理)。 这样解释,你应该就可以了然了。 1.钾(K) 2.钙(Ca) 3.钠(Na) 4.镁(Mg) 5.铝(Al) 6.锌(Zn) 7.铁(Fe) 8.锡(Sn) 9.铅(Pb) 10.氢(H) 11.铜(Cu) 12.汞(Hg) 13.银(Ag) 14.铂(Pt) 15.金(Au) K(钾) Ca(钙) Na(钠) Mg(镁) Al(铝) Zn(锌) Fe(铁) Sn(锡) Pb(铅) (H)(氢) Cu(铜) Hg(汞) Ag(银) Pt(铂) Au(金)这是由活泼到不活泼排列的,K(钾) Ca(钙) Na(钠) Mg(镁) Al(铝) Zn(锌) Fe(铁) Sn(锡) Pb(铅)都是较活泼的,可以在酸性溶液中置换出H2(氢气),而Cu(铜) Hg(汞) Ag(银) Pt(铂) Au(金)则是较不活泼的,在酸性溶液中不能置换出H2(氢气). 在非金属之间也有同样的情况,例如:F(氟) Cl(氯) Br(溴) I(碘)等非金属也可以发生置换反应!~ 还有稀有气体则是氦 氖 氩 氪 氙 氡是很不活泼的,一般情况下不与其他物质反应!

化学电子排布式规律

化学电子排布式规律应遵循能量最低原理、Hund(洪特)规则和Pauli(泡利)不相容原理。1、能量最低原理。能量最低原理是指通过对基态原子的核外电子进行排布,使整个原子的能量处于最低状态,而非是使电子尽可能地排布在能量最低的原子轨道。2、Pauli(泡利)不相容原理。Pauli不相容原理是指每个轨道(原子轨道中的轨道)最多只能容纳2个电子,且自旋方向相反(↑↓)。3、Hund(洪特)规则。Hund规则是指在能量相等的简并轨道上,电子优先以自旋方向相同的方式分别占据不同的简并轨道,使原子的总能量最低。

婴儿中药退热贴的配方

  婴儿由于刚出生时年龄不大,对外界的病菌抵抗能力也比较弱,所以容易收到一些病菌的侵扰。从而导致一些发烧发热的情况,有的家长可能会用婴儿中药退热贴来去给婴儿退烧。都是家长也是有一个疑问,婴儿中药退热贴的配方是什么? 婴儿中药退热贴的配方是什么   一种中药小儿退热贴剂的制作方法本发明公开了一种中药小儿退热贴剂,属于药物组合物的发明。该贴剂包括麻黄、桂枝、生石膏、冰片、氮酮、医用压敏胶,经粉碎、混合、搅拌成药胶乳液,进入盘旋式药膜涂布机,涂布后剪裁制成。本发明小儿退热贴剂的配伍较市面上的同类型产品药物简单,药物种类少,但药效不减。外形剪裁成两条边为两个弧度不同的圆弧,即为月牙形,符合人体耳后的构造,防脱落的同时还可以提高散热效率。   特别是一种中药小儿退热贴剂。小儿发热是小儿感染性疾病中常见的病理过程,不仅影响的孩子的发育,还可能带来其它并发症。如果小儿持续高热,就可能影响大脑的发育,所以我们在照顾发热的小儿时,首先就是控制体温,不能烧的太高。世界卫生组织建议2个月以内的婴儿禁止使用任何退热药品。除了药物退热,运用一些物理降温方法也可以帮助发热的孩子退热,其中最简单快捷的办法就是用退热贴为孩子进行物理降温。小儿退热贴是一种新型的物理降温用品。   现有的小儿退热贴存在着如下一些问题。首先,在药物组分上,很多同类型的产品多采用大组方,大配方,药物种类众多;第二,大多退烧贴采用物理退热辅以西药,而本发明采用纯天然中药材成分,副作用小,中药成分还能有效的配合物理方式增强退热功效。   本发明公开了一种中药小儿退热贴剂,属于药物组合物的发明。该贴剂包括麻黄、桂枝、生石膏、冰片、氮酮、医用压敏胶,经粉碎、混合、搅拌成药胶乳液,进入盘旋式药膜涂布机,涂布后剪裁制成。本发明小儿退热贴剂的配伍较市面上的同类型产品药物简单,药物种类少,但药效不减。外形剪裁成两条边为两个弧度不同的圆弧,即为月牙形,符合人体耳后的构造,防脱落的同时还可以提高散热效率。 婴儿退热贴用法   退热贴是通过水汽化吸热的物理变化达到迅速降温的效果。它具有高烧应急、安全退热、快速降温、保护大脑等特点,属于常用物理降温用品,所以被广泛运用于小儿感冒发烧。代表的有降落伞退热贴、冰护士退热贴等。   小儿退热贴是有用的,有一定的治疗效果,主要是通过物理降温的方式缓解小儿发热。其原理是通过凝胶中水份汽化挥发,带走体内过多的热量,从而达到降低体温的效果。小儿退热贴多数是非药物的,临床上退热的同时建议辅助其他的药物治疗,效果会更好些。退热贴的持续作用在6小时左右,贴于宝宝的额头、脐部或者其他部位,家长要注意及时更换,以免长时间刺激宝宝皮肤。   小儿退热贴使用的是物理降温原理,可以起到一定的退烧作用,有利于体温尽快恢复正常,并且可以帮助缓解因发烧出现的头疼头晕症状。但是退热贴并不能从根本上治疗发烧,只能辅助改善和控制病情,患者在发烧严重时就需要及时服用扑热息痛、安乃近等退烧药物,还要注意对身体的护理,最好大量饮用白开水,不要让自身受凉受寒,定时测量一下体温度数。
