小波分析(wavelet analysis), 或小波变换、小波转换(wavelet transform)是指用有限长或快速衰减的、 ??为母小波(mother wavelet)的震荡波形来表示信号。该波彠被 缩放 和 平移 以匹配输入的信号。 小波一词由 Jean Morlet 和 Alex Grossman 在 1980年代 早期建立。他们用的是 法语 词ondelette - 意思就是"小波"。在英语里,后来将"o de"变为"wave"而成了wavelet。 小波变换删成两个大类: 离散小波变换 (DWT) 和 连续小波变换 (CWT)。两者的主要区别在于,连续变捠在所有可能的缩放和平移上操作,而禠散变换采用所有缩放和平移值的特定孠集。 小波理论和几个其他课题相关。 ??有小波变换可以视为 时域频域表示 的形式,所以和 调和分析 相关。所有实际有用的离散小波变换䠿用包含 有限脉冲响应 滤波器的滤波器段(filterbank)。构成CWT砄小波受 海森堡 的 测不准原理 制约,或者说,离散小波基可以在 测不准原理 的其他形式的上下文中考虑。一、高考代词考点扫描
代词是英语语法结构中的重要一环,也是高考测试的重点内容之一。纵观历年高考试题,出现频率最高的是不定代词,其次是it用法、疑问代词、反身代词以及人称代词等。本文结合高考试题,对不定代词的易考点进行归纳,以帮助同学们更好地掌握这一语法现象。
1. 名词替代词one, ones, that, those的区别
one和ones用来代替前面提到过的可数名词,one指代单数,ones指代复数,所替代的是同名异物,表示泛指,可有前置定语或后置定语,也可单独使用。特指时必须加定冠词the。
that用来代替前面提到过的单数可数名词或不可数名词,不能和冠词连用,其后常有修饰语。代替可数名词的复数时,用代词those。
【原题再现】
We needed a new cupboard for the kitchen. So Peter made ________ from some wood we had.
A. it B. one C. himself D. another
【解析】 one替代上文中的cupboard,表示泛指意义;it则用于指代上文提到的原事原物。答案为B。
2. all, both, either, neither, each, none的用法比较
both, either和neither都表示两者,可作主语、宾语和定语。both还可作同位语。neither表示两者否定;either表示两者中任何一个,强调个体;both表示"两者都"。
all和none表示三者或三者以上。all表示全部肯定,而none表示全部否定。all可作主语、宾语、表语、定语和同位语;none可作主语、宾语和同位语,但不能作定语。all作主语时,指人时看作复数,指事物时看作单数;none作主语,看作单复数皆可。both, all, each, none作主语同位语时,通常放在行为动词的前面,be动词、助动词和情态动词的后面。all和both与not连用表示部分否定。
【原题再现】
① I invited Joe and Linda to dinner, but ________ of them came.
A. neither B. either C. none D. both
【解析】由but可知,第二句话表示否定意思,对两者的否定用neither。答案为A。
② I had to buy ________ these books because I didn't know which one was the best.
A. both B. none C. neither D. all
【解析】 best是最高级形式,表示三者以上。根据句意"因为不知道哪一本最好,我只好把这些书全买下来"可知,答案为D。
③-Do you want tea or coffee?
-________. I really don't mind.
A. Both B. None C. Either D. Neither
【解析】 问话中使用了or,表示让对方选择茶或咖啡,根据答句: I really don't mind.可知答案应选C。
3. other, the other, another, others的用法比较
指代单数时,若是泛指,用another;若是特指,则用the other。
指代复数时,若是泛指,用other修饰名词的复数形式;若是特指,用the other修饰名词的复数形式。
others不能作定语,表示复数意义,相当于"other+复数名词";the others相当于"the other+复数名词"。
another一般表示单数,其后接可数名词的单数形式。但若其后有数词或few时,则可接复数名词。
【原题再现】
① One of the sides of the board should be painted yellow, and ________.
A. the other is white B. another white C. the other white D. another is white
【解析】 根据常识,板子有两个面,不能用another;这是一个省略句,在the other和white之间省略了should be painted。选项A具有很大的干扰性,the other is white的意思是"另一面是白色的",而不是"漆成白色的"。故答案为C。
② I have done much of the work. Could you please finish________in two days?
A. the rest B. the other C. another D. the others
【解析】 work是不可数名词,不能用the others代替;the rest既可指代可数名词,也可指代不可数名词。故答案为A。
4. some, any及其相应复合不定代词的辨析
some多用于肯定句,any多用于否定句、疑问句。在下列情况下常用some:
1) some后接单数可数名词,意为"某一"时,相当于"a certain + 单数可数名词"。
2) 在表示请求或邀请的句子中,当期望对方给予一个肯定的答复时,通常用some,不用any。
在下列肯定句中常用any:
1) 用于陈述句或祈使句中,意为"任何;无论哪一个",后接可数名词单数形式。如:
Any book will do-I just want something to read on the train.
2) 用于肯定的条件句中,意为"什么;一个(些)";if any是固定词组,意为"若有的话"。如:
He asked me if I had any books in my desk.
some, any, every常与-one, -body, -thing构成复合不定代词,其基本用法与some, any, every用法相当。
【原题再现】
①-When shall we meet again?
-Make it ________ day you like; it's all the same to me.
A. one B. any C. another D. some
答案为B。
② I agree with most of what you said, but I don't agree with ________.
A. everything B. anything C. something D. nothing
【解析】not...everything是部分否定。
答案为A。
