烷烃:1.溴水:分层,上层有颜色2.高锰酸钾溶液:分层,下层有颜色
烯炔烃:1.溴水:褪色2.高锰酸钾溶液:褪色.
苯:1.溴水:分层,上层有颜色2.高锰酸钾溶液:分层,下层有颜色 (与烷烃一致难鉴别)
甲苯:使高锰酸钾容易褪色.(带有α氢的芳香烃都能使高锰酸钾褪色)
醇:加热下能使酸性高锰酸钾溶液褪色
醛:与氢氧化银氨溶液生成银沉淀(银镜反应).还有个你知道的用新制氢氧化铜鉴定醛.溴水和高锰酸钾都能褪色
酸:酸指示剂就行,也可以用碳酸盐等.
酯:性质较稳定.酸碱性条件下都能水解成酸和醇.不具还原性,所以溴水和高锰酸钾都不能褪色.一般酯的密度都比水小.不溶于水,溶于有机溶剂.

对称轴x=-(4a+1)/4b=-1/4
设直线x-y=0,满足x-y>=-1/4的部分在直线上半部,又x,y属于[0,1]
满足条件的区域是直线x-y=0与y=1,y轴的相交区域
这个区域面积容易算得是1/2*3/4*3/4=9/32
全部的面积是1,所以概率是9/32

证法一:先证明个引理
f(x)在点x0可导的充要条件是在x0的某领域U(x0)内,存在一个在点x0连续的函数H(x),使f(x)-f(x0)=H(x)(x-x0)从而f'(x0)=H(x0)
证明:设f(x)在x0可导,令 H(x)=[f(x)-f(x0)]/(x-x0),x∈U'(x0)(x0去心领域);H(x)=f'(x0),x=x0
因lim(x->x0)H(x)=lim(x->x0)[f(x)-f(x0)]/(x-x0)=f'(x0)=H(x0)
所以H(x)在点x0连续,且f(x)-f(x0)=H(x)(x-x0),x∈U(x0)
反之,设存在H(x),x∈U(x0),它在点x0连续,且f(x)-f(x0)=H(x)(x-x0),x∈U(x0)
因存在极限lim(x->x0)H(x)=lim(x->x0)[f(x)-f(x0)]/(x-x0)=lim(x->x0)f(x)=H(x0)
所以f(x)在点x0可导,且f'(x0)=H(x0)
引理证毕.
设u=φ(x)在点u0可导,y=f(u)在点u0=φ(x0)可导,则复合函数F(x)=f(φ(x))在x0可导,且F'(x0)=f'(u0)φ'(x0)=f'(φ(x0))φ'(x0)
证明:由f(u)在u0可导,由引理必要性,存在一个在点u0连续的函数H(u),使f'(u0)=H(u0),且f(u)-f(u0)=H(u)(u-u0)
又由u=φ(x)在x0可导,同理存在一个在点x0连续函数G(x),使φ'(x0)=G(x0),且φ(x)-φ(x0)=G(x)(x-x0)
于是就有,f(φ(x))-f(φ(x0))=H(φ(x))(φ(x)-φ(x0))=H(φ(x))G(x)(x-x0)
因为φ,G在x0连续,H在u0=φ(x0)连续,因此H(φ(x))G(x)在x0连续,再由引理的充分性可知F(x)在x0可导,且
F'(x0)=f'(u0)φ'(x0)=f'(φ(x0))φ'(x0)
证法二:y=f(u)在点u可导,u=g(x)在点x可导,则复合函数y=f(g(x))在点x0可导,且dy/dx=(dy/du)*(du/dx)
证明:因为y=f(u)在u可导,则lim(Δu->0)Δy/Δu=f'(u)或Δy/Δu=f'(u)+α(lim(Δu->0)α=0)
当Δu≠0,用Δu乘等式两边得,Δy=f'(u)Δu+αΔu
但当Δu=0时,Δy=f(u+Δu)-f(u)=0,故上等式还是成立.
又因为Δx≠0,用Δx除以等式两边,且求Δx->0的极限,得
dy/dx=lim(Δx->0)Δy/Δx=lim(Δx->0)[f'(u)Δu+αΔu]/Δx=f'(u)lim(Δx->0)Δy/Δx+lim(Δx->0)αΔu/Δx
又g(x)在x处连续(因为它可导),故当Δx->0时,有Δu=g(x+Δx)-g(x)->0
则lim(Δx->0)α=0
最终有dy/dx=(dy/du)*(du/dx)

1、因为x∈A,所以x=0或1; y∈B,故y=2或3
当x=0时,z=0,
当x=1,y=2时,z=6;当x=1,y=3时,z=12,所以A⊙B={0,6,12},选答案D
2、P+Q={a+b|a∈P,b∈Q},即P+Q中的元素是a+b的所有的值,a=0,2,5;b=1,2,6
a=0时,分别令b=1,2,6得a+b=1,2,6
a=2时,分别令b=1,2,6得a+b=3,4,8
a=5时,分别令b=1,2,6得a+b=6,7,11
综上,a+b=1,2,6,3,4,8,7,11
所以P+Q={1,2,6,3,4,8,7,11}共8个元素

通入硫化氢气体使之达到饱和
即当Cu2+完全反应生成0.2mol/L H+ 后,溶液中硫化氢气体还饱和,则溶液中硫化氢浓度为0.1 mol/L (这是分析化学常识)

计算溶液剩余的Cu2+可由下式直接求
Cu2+ + H2S= CuS ↓ + 2H+
X 0.1 mol/L 0.2 mol/L
(0.2)^2 /[0.1*X]=(Ka1*Ka2 )/Ksp-----(1)

正极:фCuS/Cu= ф0Cu2+/Cu+ 0.0591/2*lg[Cu2+] -----(2)
负极: фZn2+/Zn=-0.763 V
则:0.760 V=фCuS/Cu-(-0.763V)
фCuS/Cu=-0.003V 然后代入(2)式
解得:[Cu2+]=2.45*10^-12mol/L
再代入(1)式得
Ksp=5.7*10^-33
(没有按有效数字规则计算)

--------------------
当然也可由电池计算[Cu2+]
正极:фCuS/Cu= ф0Cu2+/Cu+ 0.0591/2*lg[Cu2+] -----(2)
负极: фZn2+/Zn=0.763
则:0.760 V=фCuS/Cu-(-0.763V)
фCuS/Cu=-0.003V 然后代入(2)式
解得:[Cu2+]=2.45*10^-12mol/L

然后再分布系数计算[S2-]
[S2-]=c(H2S)* Ka1*Ka2 /{[H+]^2 +[H+]*Ka1+ Ka1*Ka2 }
=0.1mol/L * [ (1.3*10^-7)*(7.1*10^-15) ] / { (0.2)^2 + 0.2*(1.3*10^-7) + (1.3*10^-7)*(7.1*10^-15)}=2.31*10^-20mol/L
Ksp(CuS)=[Cu2+]*[S2-]=(2.45*10^-12)*(2.31*10^-20)=5.7*10^-33

自己画图,经过第一个磁场后速度角与X轴53度,这用(R-h)^2+(2h)^2=R^2可得.

底面周长为2πr,扇形弧长为nπl/180
二者相等,则有2πr=nπl/180
r/l=n/360
简单总结为:半径是母线的几分之几,那么扇形圆心角就是360的几分之几
因此第一题:∠BOC也是360度的1/2,所以是180度
(2)l=3r,r=l/3,n=360/3=120;l=4r,n=90
(3)l=nr,圆心角=360/n

For three years, a new TV program appeared in China, the game Aquatic with foam modules. It includes physical activities which already existing such as rock climbing, diving, swimming, running, jumping ... All these activities constitute the obstacle course, but what makes it special and innovative is that these activities are performed on the water. This TV program won a great success in China with a large public. Many Chinese TV stations have opened similar programs to motify the courses and rules. This program is novel and has brought a new form of sport. Originally the idea is very simply to encourage people to exercise in the context of the Beijing Olympic Games in 2008, and it has achieved a tremendous success by the telecast, the game is now considered a sport in China with its own règles. Our micro project is inspired by this new concept, and we wish to westernize it, like a modern intercity and innovative. We want to build our company which offer the sports courses adjustables on the water. Our goal is to create a new hobby that is based on the creation of a sports service aquafun named: Aquamoov
This is to set up our foamy course on top of lakes, ponds, sea. The goal is to offer several courses sportives and recreationals. The course consist of competitive barriers which is built by obstacles worthy of Olympic disciplines: the hedges, the horizontal bar, the swimming ... Our goal is to play sports while increasing pleasure. Why do sports? To have fun, keep fit, lose weight, manage stress ... Indeed, studies show that pleasure is the primary motivation among young people for sport. So our customers are particularly young people, what are the benefits of our business. The course consists normally 5 to 7 Barriers. Each obstacle has its own name, the participants fall into the water as punishment.

Love a person is very bitter.Why I can't stop pay!
You PinTing gracefuls and the charm of the,delicate and charming pretty appearance,dignified and good manners,elegant and generous manner of speaking,start impressing me.
I think in five years later,I must still like now love you.
Everyday I see you,and power is talk with you.
No one can understand now of I,like every poet's repeated roads in general.
Really want to be with you,even his own life,and the fire of the upcoming extinguished regretless without shake.
Because of my volunteer is with you together to fly to the distant horizon
I really cannot bear,although I face hangs senseless smile,but my heart was very sad,really,many of the night I asked myself as I do wrong?
If today's every day,thoughts and love thought has dominated my thoughts,I want to control,but I can't,drizzle of the heart-to-heart lasting acquaintanceship teahouse but my love will never change!

你相信一见钟情吗?以前我总是不相信,可是当我遇见了你,我才知道一见钟情原来是那么地美好.
爱一个人是很苦的事.为什么我却不能停止付出!
你娉婷婉约的风姿,娇艳俏丽的容貌,端庄得体的举止,优雅大方的谈吐,一开始就令我刮目相看.
我想在五十年之后,我一定还是像现在一样爱你.
每天我的动力就是见到你,并和你说说话.
无人能理解现在的我,就象每个诗人的反复咏叹一般.
好想和你在一起,即使自己的生命之火即将熄灭,也无悔无撼.
因为我的志愿是和你一同飞向遥远的天边
我真的是承受不了,虽然我脸上挂着无谓的笑容,但是我内心十分难过,真的,多日的黑夜我问我自己是我做错了什么?
如今天的每一天,思念与爱念已占据了我的思想,我想控制,可是我没办法,细雨中的相识茶座中的谈心海枯石烂但我的爱永不变!
