如图为电子射线管,阴极发射电子
1.eU1=½mv0² v0=√(2eU1/m)
2.L=V0t a=F/m=eU2/md 设v⊥=v1
tanθ=v1/v0 v1=at =eU2L/mdv0
tanθ=eU2L/mdv0/v0=eU2L/mdv0²=½eU2L/½mdv0²=U2L/2dU1 (½mdv0²=Ek1=eU1)
画出速度的合成图 v2²=v0²+v1²=v0²【1+tan²θ】=eU1+(eU2²L²/4d²U1)
3.又知任意时刻,速度矢量的反向延长线必过水平位移的中点
附证明:
∴tanθ=y/(½L+R)
∴y=(½L+R)×U2L/2dU1

6关于语音的几个概念:
Phonics 是一种(方法), 是教育学习者从字母排列中去拼读出单个字来.
AHD表示美语发音,The American Heritage Dictionary of the English Language(简称AHD)
KK音标是一套(注音符号系统),是由John Samuel Kenyon 和 John Albert Knott两位美国学者共同编著的发音词典A Pronouncing Dictionary of American1956中用于标注美式发音的符号系统, 这是一套最常用的也是最权威的注音法,从此人们把美语标准发音惯称为KK音标。
DJ是根据英国学者Daniel Jones编的英语发音字典 (English Pronouncing Dictionary, 1963)中的标音而来.
英式读音根据的是English Pronouncing Dictionary 《英语正音辞典》。它们代表了被称为“Received Pronuciation”(RP)(标准读音)的读音,这在受过教育的英国人尤其是南部英格兰人中通用。
1888年国际语音协会 (International Phonetic Association) 的语言学家便制定出一套可国际通用的语音符号叫国际音标符号 (IPA—International Phonetic Alphabet),希望以一个符号代表一音,并避免各人使用一套自己的符号所产生的不便。
国内的英文字典里最常见的音标为英式发音的国际音标 (DJ) 和美式发音的KK音标,前者乃根据Daniel Jones编的英语发音字典 (English Pronouncing Dictionary, 1963),后者则是根据John S. Kenyon Thomas A. Knott二氏的美语发音字典 (A Pronouncing Dictionary of American English, 1956)。值得一提的是,KK音标所使用的符号均从前面提到的国际音标符号 (IPA) 而来,Kenyon Knott二氏仅将其中适用于美式英语的符号截取出来。
音素: 音的最小单位,英语中有48个音素.
音节: 由元音和辅音构成的发音单位.
元音: 发音响亮,是乐音,口腔中气流不受阻碍,是音节的主要组成部分.英语中有20个元音. 辅音: 发音不响亮,是噪音,口腔中气流受到阻碍,不是音节的重要组成部分,英语中有28个辅音.
开音节: 1)辅音+元音+辅音+不发音e kite cake name bike make take home plane shine
2)辅音+元音 he hi go no do be tree three hello
闭音节: 1)辅音+元音+辅音 sit bed bad bag hot hop let mad map head
2)元音+辅音 it is of in on up out ant
重读音节词尾的字母组合oo发音素[u:]的音。如:too(太;也),zoo(动物园),room(房间)等
; II. 在辅音字母f, l, m, n, s前的字母组合oo也发音素[u:]的音。如:roof(屋顶),sch
ool(学校),soon(不久),goose(鹅)等.有一个特例词要特别注意,它就是:wool[u](羊毛);
III. 在字母t前的字母组合oo发音素[u:]的音。如:boot(靴子),tooth(牙齿),特例词:foot[
u](脚); IV. 字母组合oo在字母d和k前发音素[u]的音。如:good(好),book(书),look(看)
,特例词:food[u:](食物); V. 在复合词的非重读音节中的字母组合oo发音素[u]的音。如
:bedroom(卧室),classroom(教室)等; VI. 在字母l和d之间的字母组合oo发音素[]的音。
如:blood(血),flood(洪水)等. [笨笨猪]谢谢你讲得这么详细,你能为我归纳出一个巧记
方法吗? [聪明猴]Let me try!(我试试看!)可以这样记: oo读长还是短,记住口诀就简
单。 d, k之前读短[u],food一词是特例; t前读长[u:],foot需要特殊记; 复合词中
要读短,其余多数读长[u:]; l, s, d间读作[],例外还要特殊记
