高三化学选修6课件：第3章 物质的检验
（一）几种常见仪器精确度
1、量筒属粗量器，不需估读,其精确度≥0.1ml 。量筒的精确度 是指我们量液体时的最小区分度，不同量程的量筒有着不同的精 确度，量程越小其对应的精确度也就越高，具体精确度就是量筒 刻度线上的最小格。若量程为5mL的量筒的最小刻度为0.1mL， 其精确度为0.1mL；若量程为10mL的量筒的最小刻度为0.2mL， 其精确度为0.2mL；量程为50mL的量筒的最小刻度为1mL，其 精确度为1mL等等。常见的较精确的量筒只能记录到小数点后一 位有效数值，如7.2mL。
3.计算结果的精度问题 由上述演算得到以下结论： a）对于加减法，控制精度的方法采用大家熟悉的
保留小数点后几位的办法是正确的。 b）对于乘除法，必需采用有效位数的概念，这样
才能得到相对准确的结果。
（2）光电比色法是在光电比色计上测量一系列标准 溶液的吸光度，将吸光度对浓度作图，绘制工作曲线， 然后根据待测组分溶液的吸光度在工作曲线上查得其 浓度或含量。
（二）有效数字
1、有效位数的确定 有效位数一般是从第一个非零数字到最后一个数
字的长度。如3.14是三位有效数字。0.0050是两位有 效数字。5是精确数字，而5.0是两位有效数字。这里 要注意：0.5和0.50是不同的，0.5的小数点后第一位 是近似值（可能是0.45也可能是0.54通过舍入得到 的），而0.50的小数点后第二位是近似值（可能是 0.495也可能是0.504通过舍入得到的）。
对物质进行定性检测的基本方法主要有以下几种：
质谱
核磁共振波谱
（二）常见物质检验的一般程序与思路
1、固态物质的检验
待检物质
观察固体颜色初步区分
加水溶解看溶解性
根据特征反应检验
2、溶液的检验 待检溶液
高中历史人教版选修6 第三单元 第1课 雅典卫城和奥林匹亚遗址 【名师课件—集体备课】
差异：古奥运会的参赛者有种种限制，古代奥 林匹亚竞技会只允许成年男子参加和观看，是少数 人垄断的体育比赛；除基本竞赛项目外，还有模拟 战争的竞赛，如双轮马车赛，主要为战争做准备， 所以古今奥运会的比赛项目有许多的不同；古代奥 林匹亚竞技会项目很少。今天的比赛项目比古代比 赛项目有了更完善的竞赛规则和适当的保护措施， 所以竞赛的危险性大大减少。古奥运会的参赛者抱 着“或得桂冠，或舍生命”的信念，对名誉和成功 的热切追求是十分强烈的，这与今天的奥运名言 “重在参与”是完全相反的理念。

三、奥林匹亚遗址
体育源于 竞技。古希腊 最著名的竞技 会是古奥林匹 亚竞技会。
卫城： 古希腊人为了防御外敌，通常围绕
一座易守难攻的山冈建城，山顶筑有城 墙和庙宇，作为城市的最后一道防御屏 障和国家的宗教祭祀中心。这样的城中 城被古希腊人称为“卫城”。
雅典卫城复原图
此建筑是 由一座山门和 三座神庙(雅 典娜胜利神庙、 帕特农的雅典 娜神庙、伊瑞 克提翁神庙) 组成。
它兼有祭祀庆典、防卫御敌、宗 教文化及公民议政等功能。
1896年，经 顾拜旦（左图） 等有识之士倡导， 在雅典举办了第 一届现代奥林匹 克运动会。此后， 四年一届的奥运 会成为世界瞩目 的盛典。
奥林匹克的会旗
奥林匹克的会旗为白色，中间印有五个相 互套连的圆环，即我们所说的奥林匹克环。五 个环的颜色自左至右依次排列为蓝、黄、黑、 绿、红。会旗的图案是根据顾拜旦的构思设计 的。圆环的五种颜色被解释为象征五大洲：欧 洲——天蓝色，亚洲——黄色，非洲——黑色， 澳洲——草绿色，美洲——红色。

人教版英语选修6第三单元课文原文及翻译Unit 3 A healthy life 第三单元健康生活ReadingADVICE FROM GRANDADDear James,It is a beautiful day here and I am sitting under the big tree at the end of the garden. I have just returned from a long bike ride to an old castle. It seems amazing that at my age I am still fit enough to cycle 20 kilometres in an afternoon. It's my birthday in two weeks time and I'll be 82 years old! I think my long and active life must be due to the healthy life I live.This brings me to the real reason for my letter, my dear grandson. Your mother tells me that you started smoking some time ago and now you are finding it difficult to give it up. Believe me, I know how easy it is to begin smoking and how tough it is to stop. You see, during adolescence I also smoked and became addicted to cigarettes.By the way, did you know that this is because you become addicted in three different ways? First, you can become physically addicted to nicotine, which is one of the hundreds of chemicals in cigarettes. This means that after a while your body becomes accustomed to having nicotine in it. So when the drug leaves your body, you get withdrawal symptoms. I remember feeling bad-tempered and sometimes even in pain. Secondly, you become addicted through habit. As you know, if you do the same thing over and over again, you begin to do it automatically. Lastly, you can become mentally addicted. I believed I was happier and more relaxed after having a cigarette, so I began to think that I could only feel good when I smoked. I was addicted in all three ways, so it was very difficult to quit. But I did finally manage.When I was young, I didn't know much about the harmful effects of smoking. I didn't know, for example, that it could do terrible damage to your heart and lungs or that it was more difficult for smoking couples to become pregnant. I certainly didn't know their babies may have a smaller birth weight or even be abnormal in some way. Neither did I know that my cigarette smoke could affect the health of non-smokers. However, what I did know was that my girlfriend thought I smelt terrible. She said my breath and clothes smelt, and that the ends of my fingers were turning yellow. She told me that she wouldn't go out with me again unless I stopped! I also noticed that I became breathless quickly, and that I wasn't enjoying sport as much. When I was taken off the school football team because I was unfit, I knew it was time to quit smoking.I am sending you some advice I found on the Internet. It might help you to stop and strengthen your resolve. I do hope so because I want you to live as long and healthy a life as I have.Love fromGrandadHow can you stop smoking?It is not easy to stop smoking, but millions have managed to quit and so can you. Here are a few suggestions.Prapare youself. Decide on a day to quit. Don’t choose a day that you know is going to be stressful, such as the day of an exam. Make a list of all the benefits you will get from stopping smoking. Then throw away your last packet of cigarettes.Be determined. Every time you fell like smoking a cigarette, remind yourself that you are a non-smoker. Reread the list of benefits you wrote earlier.Break the habit. Instead of smoking a cigarette, do something else. Go for a walk, clean your teeth, frink some water, clean the house; in fact, do anything to keep ypur mind and especially your hands busy.Relax. If you start to feel nervous or stressed, do not raech for a cigarette. Try some deep breathing instead. Do some relaxationg exercises every time you feel stressed.Get help if you need it. Arrange to stop smoking with a friend so you can talk about your problems,or join a stop-smoking group. If you feel desperate , you might like to talk to a doctor or chemist about something to help you, like nicotine chewing gum.Keep trying. Don’t be disappointed if you have to try several times before you finally stop smoking. If you weaken and have a cigarette,do not feel ashamed. Just try again. You will succeed finally.爷爷的忠告亲爱的詹姆士：今天，这儿天气晴朗。

ADVICE FROM GRANDAD爷爷的忠告Dear James,亲爱的James，It is a beautiful day here and I am sitting under the big tree at the end of the garden. I have just returned from a long bike ride to an old castle. It seems amazing that at my age I am still fit enough to cycle 20 kilometers in an afternoon. It’s my birthday in two weeks time and I’ll be 82 years old! I think my long and active life must be due to the healthy life I live.我现在正坐在花园尽头的大树下享受着今天的好天气。
我骑了很久的自行车一直到古堡，刚刚才返回来。
像我这个年纪还能一个下午骑20公里的自行车，很令人惊讶吧。
两周后可就是我82岁的生日了！我觉得我可以如此积极的生活且长寿，必须归功于我健康的生活。

晨 醒
有学着认为：“‘度’字生动，含有飞动
炼字 意，足以唤起人活泼之意象。”你同意
这种说法吗？谈谈你的理解。
“度”即飘度，飘拂，纷披，形容头发蓬乱， 丝丝袅袅，半掩着面容，如飞飘之状。在词人 的联想中，“云”字乃从“鬓”字生出，“度”字又 从“云”字生出。词人再于“度”字前添一“欲”字， 就把无生命的“鬓云”写活了，生动地展现了女 子晨醒时鬓发散乱、面容俏丽的慵懒娇弱模样。
晨 醒
清晨，刚刚睡 醒的女子有意 无意间将头轻 轻一动，那蓬 松散乱的长长 鬓发像乌云一 样，将要拂过 那香扑扑的雪 白脸颊……
把握意象
蛾眉：即娥眉，指女子细而弯的秀眉，鲍照诗 有：“始见西南楼，纤纤如玉钩，未映东北墀， 娟娟似娥眉。”娥眉系古诗文传统意象，以对 女子眉毛美好形状的形象刻画，来代指美女的 整体气质， 常有美丽、美女、美德之意蕴。
