2003年考研数学(三)真题答案1.【分析】当≠x 0可直接按公式求导,当x=0时要求用定义求导.【详解】当1>λ时,有,0,0,0,1sin 1cos )(21=≠⎪⎩⎪⎨⎧+='--x x xx x x x f 若若λλλ显然当2>λ时,有)0(0)(lim 0f x f x '=='→,即其导函数在x=0处连续.2. 【分析】 曲线在切点的斜率为 0,即 y = ′0 ,由此可确定切点的坐标应满足的条件,再根据在切点处纵坐标为零,即可找到2b 与a 的关系.【详解】由题设,在切点处有03322=-='a x y ,有.22a x =又在此点y 坐标为0,于是有0300230=+-=b x a x ,故.44)3(6422202202a a a x a x b =⋅=-=3. 【分析】 本题积分区域为全平面,但只有当0 ≤x ≤1,0 ≤y −x ≤1时,被积函数才不为零,因此实际上只需在满足此不等式的区域内积分即可.【详解】⎰⎰-=Ddxdy x y g x f I )()(=dxdya x y x ⎰⎰≤-≤≤≤10,102=.])1[(212112a dx x x a dy dx ax x=-+=⎰⎰⎰+4. 【分析】 这里 ααT为 n 阶矩阵,而 αT= α2a 2为数,直接通过 AB =E 进行计算并注意利用乘法的结合律即可.【详解】由题设,有)1)((T T a E E AB αααα+-==TT T T aa E αααααααα⋅-+-11=T T T Ta a E αααααααα)(11-+-=TT T a a E αααααα21-+-=E aa E T=+--+αα)121(,于是有0121=+--a a ,即0122=-+a a ,解得.1,21-==a a 由于A<0,故a=-1.5.. 【分析】 利用相关系数的计算公式即可.【详解】 因为)4.0()()]4.0([()4.0,cov(),cov(---=-=X E Y E X Y E X Y Z Y =)(4.0)()()(4.0)(Y E X E Y E Y E XY E +--=E(XY)–E(X)E(Y)=cov(X,Y),且.DX DZ =于是有cov(Y,Z)=DZDY Z Y ),cov(=.9.0),cov(==XY DYDX Y X ρ【评注】 注意以下运算公式:D (X +a ) =DX ,cov(X ,Y +a ) =cov(X ,Y ).6.. 【分析】 本题考查大数定律:一组相互独立且具有有限期望与方差的随机变量n X X X ,,,21 ,当方差一致有界时,其算术平均值依概率收敛于其数学期望的算术平均值:).(1111∞→→∑∑==n EX n X n ni i p n i i 【详解】这里22221,,,n X X X 满足大数定律的条件,且22)(i i i EX DX EX +==21)21(412=+,因此根据大数定律有∑==n i i n X n Y 121依概率收敛于.21112=∑=n i i EX n 二、选择题(本题共 6 小题,每小题 4 分,满分 24 分. 每小题给出的四个选项中,只有一项符合题目要求,把所选项前的字母填在题后的括号内)7.【分析】由题设,可推出f(0)=0,再利用在点x=0处的导数定义进行讨论即可.【详解】显然x=0为g(x)的间断点,且由f(x)为不恒等于零的奇函数知,f(0)=0.于是有)0(0)0()(lim )(lim)(lim 00f x f x f x x f xg x x x '=--==→→→存在,故x=0为可去间断点.【评注1】本题也可用反例排除,例如f(x)=x,则此时g(x)=,0,0,0,1=≠⎩⎨⎧=x x x x 可排除(A),(B),(C)三项,故应选(D).【评注2】若f(x)在0x x =处连续,则.)(,0)()(lim000A x f x f A x x x f x x ='=⇔=-→.8..【分析】可微必有偏导数存在,再根据取极值的必要条件即可得结论.【详解】可微函数f(x,y)在点),(00y x 取得极小值,根据取极值的必要条件知0),(00='y x f y ,即),(0y x f 在0y y =处的导数等于零,故应选(A).【评注1】本题考查了偏导数的定义,),(0y x f 在0y y =处的导数即),(00y x f y ';而),(0y x f 在0x x =处的导数即).,(00y x f x '【评注2】本题也可用排除法分析,取22),(y x y x f +=,在(0,0)处可微且取得极小值,并且有2),0(y y f =,可排除(B),(C),(D),故正确选项为(A).9.【分析】根据绝对收敛与条件收敛的关系以及收敛级数的运算性质即可找出答案.【详解】若∑∞=1n na绝对收敛,即∑∞=1n na收敛,当然也有级数∑∞=1n na收敛,再根据nn n a a p +=,nn n a a q -=及收敛级数的运算性质知,∑∞=1n np与∑∞=1n nq都收敛,故应选(B).10.. 【分析】 A 的伴随矩阵的秩为 1, 说明 A 的秩为 2,由此可确定 a,b 应满足的条件.【详解】 根据A 与其伴随矩阵 A*秩之间的关系知,秩(A)=2,故有0))(2(2=-+=b a b a ab b b a b bb a ,即有02=+b a 或a=b.但当a=b 时,显然秩(A)2≠,故必有a ≠b 且a+2b=0.应选(C).【评注】n (n )2≥阶矩阵A 与其伴随矩阵A*的秩之间有下列关系:.1)(,1)(,)(,0,1,*)(-<-==⎪⎩⎪⎨⎧=n A r n A r n A r n A r 11..【分析】本题涉及到线性相关、线性无关概念的理解,以及线性相关、线性无关的等价表现形式.应注意是寻找不正确的命题.【详解】(A):若对于任意一组不全为零的数s k k k ,,,21 ,都有02211≠+++s s k k k ααα ,则s ααα,,,21 必线性无关,因为若s ααα,,,21 线性相关,则存在一组不全为零的数s k k k ,,,21 ,使得02211=+++s s k k k ααα ,矛盾.可见(A )成立.(B):若s ααα,,,21 线性相关,则存在一组,而不是对任意一组不全为零的数s k k k ,,,21 ,都有.02211=+++s s k k k ααα (B)不成立.(C)s ααα,,,21 线性无关,则此向量组的秩为s ;反过来,若向量组s ααα,,,21 的秩为s ,则s ααα,,,21 线性无关,因此(C)成立.(D)s ααα,,,21 线性无关,则其任一部分组线性无关,当然其中任意两个向量线性无关,可见(D)也成立.综上所述,应选(B).【评注】原命题与其逆否命题是等价的.例如,原命题:若存在一组不全为零的数s k k k ,,,21 ,使得02211=+++s s k k k ααα 成立,则s ααα,,,21 线性相关.其逆否命题为:若对于任意一组不全为零的数s k k k ,,,21 ,都有02211≠+++s s k k k ααα ,则s ααα,,,21 线性无关.在平时的学习过程中,应经常注意这种原命题与其逆否命题的等价性.12.. 【分析】按照相互独立与两两独立的定义进行验算即可,注意应先检查两两独立,若成立,再检验是否相互独立.【详解】因为21)(1=A P ,21)(2=A P ,21)(3=A P ,41)(4=A P ,且41)(21=A A P ,41)(31=A A P ,41)(32=A A P ,41)(42=A A P 0)(321=A A A P ,可见有)()()(2121A P A P A A P =,)()()(3131A P A P A A P =,)()()(3232A P A P A A P =,)()()()(321321A P A P A P A A A P ≠,)()()(4242A P A P A A P ≠.故321,,A A A 两两独立但不相互独立;432,,A A A 不两两独立更不相互独立,应选(C).【评注】本题严格地说应假定硬币是均匀的,否则结论不一定成立.13..【分析】只需求出极限)(lim 1x f x -→,然后定义f(1)为此极限值即可.【详解】因为)(lim 1x f x -→=)1(1sin 11[lim 1x x x x --+-→πππ=xx xx x πππππsin )1(sin )1(lim 111---+-→=xx x xx ππππππππcos )1(sin cos lim 111-+---+-→=xx x x xx ππππππππππsin )1(cos cos sin lim11221----+-→=.1π由于f(x)在)1,21[上连续,因此定义π1)1(=f ,使f(x)在]1,21[上连续.【评注】 本题实质上是一求极限问题,但以这种形式表现出来,还考查了连续的概念.在计算过程中,也可先作变量代换 y=1-x ,转化为求 y →0 +的极限,可以适当简化.14..【分析】本题是典型的复合函数求偏导问题:),(v u f g =,)(21,22y x v xy u -==,直接利用复合函数求偏导公式即可,注意利用.22uv f v u f ∂∂∂=∂∂∂【详解】vfx u f y x g

+=+=-【评注】本题属常规题型,明显地应该选用极坐标进行计算,在将二重积分化为定积分后,再通过换元与分步积分(均为最基础的要求),即可得出结果,综合考查了二重积分、换元积分与分步积分等多个基础知识点.16..【分析】先通过逐项求导后求和,再积分即可得和函数,注意当x=0时和为1.求出和函数后,再按通常方法求极值.【详解】.1)1()(1212∑∞=-+-=-='n n n xx x x f

求和函数一般都是先通过逐项求导、逐项积分等转化为可直接求和的几何级数情形,然后再通过逐项积分、逐项求导等逆运算最终确定和函数.17.. 【分析】 F(x)所满足的微分方程自然应含有其导函数,提示应先对 F(x)求导,并将其余部分转化为用 F(x)表示,导出相应的微分方程,然后再求解相应的微分方程.【详解】(1)由)()()()()(x g x f x g x f x F '+'='=)()(22x

【评注】介值定理、微分中值定理与积分中值定理都是常考知识点,且一般是两两结合起来考.本题是典型的结合介值定理与微分中值定理的情形.19..【分析】方程的个数与未知量的个数相同,问题转化为系数矩阵行列式是否为零,而系数行列式的计算具有明显的特征:所有列对应元素相加后相等.可先将所有列对应元素相加,然后提出公因式,再将第一行的(-1)倍加到其余各行,即可计算出行列式的值.【详解】方程组的系数行列式ba

2004全国统一考试英语B卷解析[原创]

2004年普通高等学校招生全国统一考试英语B卷试题答案与解析第一部分:听力部分1--5 ABCBA 6--10 CBCAC 11--15 ACABB 16--20 CBAAB解析(略)第二部分第一节:单项填空答案21-25 DBADC 26-30 BDACA 31-35 CDBAC解析21.本题考查交际英语的有关知识。

D选项Take your time译为“不急”“慢慢来”符合上文语境。

22.本题考查非谓语动词的用法。

题干中的语意是: 产品首次投放市场时,即获得成功。

产品是被引进市场的,强调的是被动语意,选项A introducing和选项C introduce 不表示被动,可排除;选项D being introduced表示“正在被引进”和题干语意不符;选项B introduced 表示“被引进”符合题意。

补充:连词+分词(短语)有时为使分词短语与主句关系更清楚,可在分词前加连词。

连词有:when,while,if though,after, before, as.但分词的主语和主句的主语必须为同一个。

例如:While waiting there, he saw two pretty girls come out of thebuilding.等在那儿时,他看见两个靓妹走出大楼。

(waiting 和saw 的主语相同)23.本题考查定语从句的用法。

题干中定语从句缺少表示地点的关系副词,A选项中where作为关系副词引导定语从句,指代“在裤子上”.符合题意要求。

补充:判断关系代词与关系副词方法一:用关系代词,还是关系副词完全取决于从句中的谓语动及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要用关系副词。

例如:This is the mountain village where I stayed last year. 这是我去年呆过的山村。

I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。

人工智能试题参考答案(2004年)一、单项选择题1、(C)2、(C)3、(D)4、(A)5、(D)二、用线性归结法证明子句集为:A3:(1)¬ H(x) ∨¬G(x)¬B:(2)¬ E(x) ∨¬G(x)A2:(3) D(a)(4) G(a)(5)¬F(a, y)∨ G(y)A1:(6)¬D(x) ∨E(x) ∨F(x, f(x))(7)¬D(x) ∨E(x) ∨H(f(x))顶子句可以有多种选择,如果选择(2)作为顶子句,可以归结如下:(8)¬ E(a) (2)(4)(9)¬D(a) ∨H(f(a)) (8)(7)(10) H(f(a)) (9)(3)(11)¬G(f(a)) (10)(1)(12)¬F(a, f(a)) (11)(5)(13)¬D(a) ∨E(a) (12)(6)(14)E(a) (13)(4)(15) (14)(8)归结顺序可能有更好的,这里只是做参考。

三、1、基于范例的推理系统与基于规则的专家系统做一比较答:传统的专家系统一般采用的是基于规则的推理,即RBR(Rule-based Reasoning),它是通过前因后果链(如规则链)演绎出结论的过程。

对于易于表示成启发式规则形式的问题来说RBR方法比较合适,如分类问题和诊断问题。

但是当人们遇到一个新的问题的时候,一般先是回忆,从记忆中找到一个与新的问题相似的案例(case),然后把该案例的有关信息和知识复用到新问题的求解之中。

这种问题求解策略成为基于范例的推理CBR。

CBR和RBR是不同的:在CBR中,求解一个问题的结论不同通过链式推理产生,而是从记忆里或范例库中找到与当前问题最相关的范例。

然后对该范例做必要的改动以适应当前的问题。

因此,CBR通过联想(或类比),从过去的经验出发,把过去的案例和当前面临的问题相比较做出决策的过程。

By the time Jane brought her son home, her mother was sitting in her chair, dressed and ready to welcome the baby. For two weeks, Mother clucked, smiled and held the new-born baby. Then she quietly became unconscious and, after visits from all her children, was finally free of the pain. For Jane, memories of her son’s birth will always be bittersweet, but it was at this time that she learned an important truth about living. While both joy and sorrow pass quickly, and often come together at the same time, love has the power to overcome both. And love can last forever. (371 words)

2004高教社杯全国大学生数学建模竞赛B题评阅要点

2004高教社杯全国大学生数学建模竞赛B题评阅要点

2004高教社杯全国大学生数学建模竞赛B题评阅要点[说明] 根据各赛区的建议,从2004年起全国组委会不再提供赛题参考解答,只给评阅要点。

本要点仅供参考,各赛区评阅组应根据对题目的理解及学生的解答,自主地进行评阅。

一. 理解题目应注意以下几点:1. 每条线路上的有功潮流是各发电机组出力的函数,于是有6个函数,每个函数有8个相同的自变量。

函数关系可由表1和表2近似确定。

2. 输电阻塞的定义是某条线路上的有功潮流的绝对值超出限值(表6),当出现输电阻塞时按照以下顺序依次优先处理:调整各机组出力消除输电阻塞;使用线路安全裕度(表6),但要使每条线路上潮流的绝对值超过限值的百分比尽量小;在用电侧拉闸限电。

3. 电力市场交易结果(调度计划)的制订规则和步骤:1)各机组的出力分配预案及清算价(最高段价)由三个条件决定:a)各机组的出力之和等于下一时段的负荷预报(题目中的982.4MW或1052.8MW)。

b)各机组的出力位于两个区间的交集内。

一个是从当前出力(表1方案0)出发,按照出力改变速率(表5),在15分钟时间内所能达到的范围,另一个是0与段容量之和构成的区间(如机组1当前出力是120,改变速率是2.2,于是下一时段能达到的范围是120±2.2⨯15=153/87,段容量之和为190)。

c)各机组的出力小于或等于段价(表4)不超过清算价的段容量(表3)之和,小于情况可由两种原因引起:一是由于b)中给出的约束导致选取段容量的部分;二是由于a)中给出的约束导致只能选取清算价对应的段容量的部分。

2)计算当执行上面得到的分配预案时各线路上的有功潮流,检查是否会出现输电阻塞。

如果不出现,接受该预案;否则,按照2中的步骤进行(仍需考虑机组爬坡速率和段价)。

3)当改变上述预案时,要计算阻塞费用。

需设计简明、合理的计算阻塞费用的规则,要求公平地对待序内容量不能出力的部分和报价高于清算价的序外容量出力的部分。
