环境监测知识点概括

实验室内部质量控制常用的方法:空白试验;校准曲线核查;仪器设备的定期标定;平行样分析;加标样分析;密码样品分析;编制质量控制图。 实验室外部质量控制常用的方法:常用的方法有分析标准样品以进行实验室之间的评价和分析测量系统的现场评价等。 由以上可知,误差和偏差具有不同的含义:

误差以真值为标准,而偏差以多次测定值的算术平均值为标准。但在实际分析中,真值所以,并不强调误差和偏差的严格区别,而往往将两者一般地称为“误差。 一个工业区布置9个空气采样点,某天测得各点上TSP 日平均浓度为:1.85,1.86, 1.93, 2.01,2.03,2.05,2.07,2.12,2.15mg/m3。当α=0.01时,求该区那天TSP 浓度变化的置信区间(设已知该地TSP 浓度呈正态分布)。 解:

自由度 f = n-1 = 8 显著性水平 α = 0.01 = 1% 查表得 t0.01,(8)= 3.36 将数据代入公式,得置信区间为 [1.89,2.31] 则 1.89≤μ ≤ 2.31 也即,有99%的把握推断该地区那天的 TSP 浓度变化范围在1.89至2.13之间。 某种方法经过改进,其精密度是否有变化; 相同试样由不同的分析人员或不同分析方法所测得均数是否有差异; 对标准样的实际测定均值与其保证值之间的差异,到底是由抽样误差引起的,还是确实存在本质的差别; 以上问题,均可用“t 检验”,即“显著性检验”来加以检验。 [例] 某含铁标准物质,已知铁的保证值为1.05%,对其10次测定的平均值为1.054%,标准偏差为0.009。检验测定结果与保证值之间有无显著性差异。 解] [ (1) =-2.11 (2)给定 α =0.05, =9, 查得 = 2.26 1-=n f ) 9(05.0t

高考英语动词时态和语态讲解与专项练习题

动词时态语态 汉语的时态大多是通过副词来表达的,而英语的时态是靠动词的变化和时间状语来表达的。英语中常考的或较常用的有10种,而且重点测试完成时态。要掌握英语的时态和语态,必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。 1、一般现在时;主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语;表示客观规律和永恒真理;按照计划安排好了将要发生的动作(一般指时刻表)等。 He usua lly goes to work at 7 o’clock every morning. She has a brother who lives in New York. The earth goes around the sun. Guangzhou is situated in the south of China. 考点一:表示永恒的真理,即使出现在过去的语境中,仍用一般现在时。如:I learned that the earth goes around the sun when I was in primary school. 考点二:在时间和条件状语从句中,代替一般将来时;常用的引导词有:时间:when, until, after, before, as soon as, once, the moment/the minute, the day; 条件:if, unless, provided. If he accepts the job, he will get more money soon. 考点三:在make sure (certain), see to it, mind, care, matter +宾语从句,从句用一般现在时代替一般将来时。 So long as he works hard, I don’t mind when he finishes the experiment. 只要他努力工作,我不介意他什么时候做完试验。 考点四:在the more… the more … (越……越……) 句型中, 若主句是一般将来时, 从句用一般现在时。 The harder you study, the better results you will get. 2、现在进行时 表说话时或目前一段时间正在进行的活动:或表感情色彩,加强语气。与频率副词,如always,constantly,continually,again等连用表示说话人的某种感情色彩(赞叹、厌烦、埋怨等)。 We are having English class. The house is being built these days. The little boy is always making trouble. 考点一:在时间状语或条件状语从句中表示将来正在进行的动作。Look out when you are crossing the street. Don't wake him up if he is still sleeping at 7 tomorrow morning. 考点二:表示在最近按计划或安排要进行的动作(这时多有表示将来的时间状语)。 Marry is leaving on Friday. 3、现在完成时 表示动作发生在过去,完成在过去,但强调与现在情况仍有联系,其结果或影响仍存在。现在完成时有一些标志性的时间状语: (1)非延续动作:动作发生在过去,对现在有影响。(2)延续性动作:动作和状态的持续。现在完成时有一些标志性的时间状语: 考点一:for + 时间段;since + 时间点 They have lived in Beijing for five years. They have lived in Beijing since 1995. 考点二:常见的不确定的时间状语:lately; recently, just, already, yet, up to now; till now; so far, these days, Has it stopped raining yet ? 考点三:在表示“最近几世纪/ 年/ 月以来……”时间状语中,谓语动词用现在完成时。
