tibble::tibble,object of POWER data includ-ing location,dates(not including“climatology”)and requested parameters.A decorative header of metadata is included in this object.Argument details for“community”There are three valid values,one must be supplied.This will affect the units of the parameter and the temporal display of time series data.ag Provides access to the Agroclimatology Archive,which contains industry-friendly parameters formatted for input to crop models.sb Provides access to the Sustainable Buildings Archive,which contains industry-friendly param-eters for the buildings community to include parameters in multi-year monthly averages.re Provides access to the Renewable Energy Archive,which contains parameters specifically tai-lored to assist in the design of

鼻通气功能客观评价

鼻通气功能客观评价

鼻通气功能客观评价张伟;张罗【摘要】Nasal obstruction is one of the most common complaints in rhinologic practice. There are subjective and objective methods available; for the assessment of nasal patency. Currently, visual analogue scale, based on what the subjects feel, is the most widely used subjective assessment of nasal obstruction. Objective assessment of nasal patency and nasal physiology includes the use of rhinomanometry and acoustic rhinometry, which respectively provides the relationship between pressure and airflow, and a mimic topographic map of the nasal cavity. This review focuses on rhino manometry and its application in clinical practice.%鼻通气功能障碍(鼻塞)是鼻病理状态时最常见的症状之一.评价鼻塞的程度既可以采用主观评估法也可采用客观测定法.目前主观评估临床上主要采用的是视觉模拟量表评分(visual analogue scale,VAS),即以受试者的主观感受来评定鼻塞的程度.鼻阻力测定(rhinomanometry,RMM)和鼻声反射测定(acoustic rhinometry,AR)是目前临床最常用的客观评价鼻腔通气状况的方法,前者主要测定的是鼻内压力和气流,后者主要反映的是鼻腔内部解剖学改变.鼻通气功能客观评价在疾病辅助诊断、治疗方法的选择和疗效评价等方面具有广泛的应用价值.本文将着重就鼻通气功能的客观评价特别是鼻阻力的测定技术作一综述.【期刊名称】《首都医科大学学报》【年(卷),期】2012(033)006【总页数】5页(P740-744)【关键词】鼻塞;鼻阻力;鼻测量;声学【作者】张伟;张罗【作者单位】首都医科大学附属北京同仁医院耳鼻咽喉头颈外科,北京市耳鼻咽喉科研究所教育部耳鼻咽喉头颈外科重点实验室,北京,100730;首都医科大学附属北京同仁医院耳鼻咽喉头颈外科,北京市耳鼻咽喉科研究所教育部耳鼻咽喉头颈外科重点实验室,北京,100730【正文语种】中文【中图分类】R765鼻塞是鼻部病理状态时最常见的症状。

Methods From March 2018 to January 2020, 131 patients with structuralnasal obstruction who were admitted to our hospital were selected as the subjects, and the visualanalogue score was used to score the situation of nasal obstruction. According to the results, theywere divided into 36 cases of mild nasal obstruction group, 57 cases of moderate nasal obstructiongroup, 38 cases of severe nasal obstruction group, and 42 cases of physical examination at the sametime were selected as the control group. Nasal acoustic reflex and nasal resistance were measuredin each group. The results of nasal acoustic reflex and nasal resistance were compared among thegroups, and Pearson correlation analysis method was used to analyze the correlation between thetotal expiratory phase resistance, the total inspiratory phase resistance and the measurement indexof nasal structure. Results There was significant difference in the measurement of nasal acousticreflex among the groups(P<0.05); there was no significant difference in the total nasal resistancebetween the control group and the mild and the moderate nasal obstruction groups, and there wassignificant difference between the severe nasal obstruction groups; the difference of right-left nasalresistance ratio between the mild, the moderate and the heavy nasal obstruction groups was higherthan that of the control group(P<0.05), and the severe nasal obstruction group was higher than thatof the control group(尸<0.05); There was a negative correlation between the total inspiratory phaseresistance, the total expiratory phase resistance and the distance of the inferior turbinate front tonasal septum(DTNS), The minimal distance between the inferior turbinate soft tissue(MDTT) andthe minimal distance between the inferior turbinate bone(MDTB). The difference was statisticallysignificant(戶<0.05). Conclusions Nasal acoustic reflex and nasal resistance test can be used toevaluate the nasal ventilation function of patients with structural nasal ventilation disorders.

儿童下鼻甲肥大诊断标准

儿童下鼻甲肥大诊断标准

儿童下鼻甲肥大诊断标准英文回答:Diagnosis criteria for adenoid hypertrophy in children include:1. Nasal obstruction: Children with adenoid hypertrophy often present with nasal congestion, difficulty breathing through the nose, and snoring during sleep.2.

The NASA Astrophysics Data System Obsolescence of Reads and Cites

The NASA Astrophysics Data System Obsolescence of Reads and Cites

Library and Information Services in Astronomy IVJuly2-5,2002,Prague,Czech RepublicB.Corbin,E.Bryson,and M.Wolf(eds)The NASA Astrophysics Data System:Obsolescence ofReads and CitesMichael J.Kurtz,Guenther Eichhorn,Alberto Accomazzi,Carolyn S.Grant,Donna M.Thompson,Elizabeth H.Bohlen,and Stephen S.MurrayHarvard-Smithsonian Center for Astrophysics,Cambridge,MA02138USAkurtz@Abstract.The obsolescence of an article,how its use declines as it ages,has long been a central element of bibliometric studies.Normally this is de-termined using the citations to an article.We determine this function using the reads an article receives and then compare this with the func-tion determined from a citation study.There are both similarities and differences.The similarities are strong enough that the normative theory of citations must be true in the mean.1.Readership as a function of ageBecause the use of the Astrophysics Data System(ADS)is now the dominant means by which astronomers access the technical literature the ADS usage logs can provide a uniquely powerful view of the way an entire discipline(astronomy) uses the technical literature.Here we will examine the obsolescence(e.g.White and McCain(1989),Line and Sandison(1975))of the technical literature of astronomy as a function of article age based on the actual readership of an article.This is an extension and reexamination of the work done in Kurtz et al.(2000).We use,as our basic data source,the log of all article“reads”using the ADS between Januaryfirst and August20th,2001.We define a“read”as every time a user,who has access to a list of articles,their dates,journal names,titles and authors,chooses to view more information about an article.Currently50% of these“reads”are of the abstract,38%are of one of the forms of whole text, 8%are of the citation list,and the rest are distributed amongst the ten other options.There are more than4.2million“reads”in this log.For this study we extracted those for any of the three major U.S.astronomy journals The Astrophysical Journal,The Astronomical Journal,and The Pub-lications of the Astronomical Society of the Pacific.All three of these journals have been stable over the past century,are currently among the most important astronomy journals,and have had their full text versions beginning with their first issues available on-line through ADS since well before the beginning of the223224M.Kurtz et al.190019201940196019802000110100publication yearHCI 19751980198519901995200010100publication year H C IFigure 1.LEFT:The average number of reads per article per year for three U.S.astronomy journals.The thin line represents the actual data,the thick line is the model in the text,and the three dotted lines represent the three components of the model.RIGHT:An expanded view showing the most recent 25years.Note that the model fits the actual data very well.reporting period.These journals accounted for slightly more than 1.8million reads in the first 7.66months of 2001.1.1.The obsolescence model for readsFigure 1—LEFT shows the average number of reads per article per year for these three journals as a function of publication year.This shows more than a full century from the first issue of The Publications of the Astronomical Society of the Pacific in 1889through 2000.Figure 1—RIGHT shows an expanded view of the last 25years of data from figure 1—LEFT.The dotted lines show the relevant three components of the four component readership model of Kurtz et al.(2000),as modified here.In this model research article readership (R)is parameterized by the sum of four exponential functions with very different time constants;we associate these four functions with four different modes of readership:Historical (R H ),Interesting (R I ),Current (R C )and New (R N ).The New (R N )mode,which corresponds to the newly arrived (either on-line or in the mail)issue,cannot be parameterized by the data in figures 1—LEFT and 1—RIGHT.The Historical (R H )mode we actually parameterize as a constant,H 0.We leave the exponential form in equation C (with k H =0)because other combinations of multiplicative and time constants can also be found which fit the data well,including some combinations with k H =0.R =R H +R I +R C +R N(C )whereR H =H 0e −k H TNASA ADS:Obsolescence of Reads and Cites225R I=I0e−k I TR C=C0e−k C TR N=N0e−k N TandH0=1.5;k H=0I0=45;k I=0.065C0=110;k C=0.4N0=1600;k N=16The three longer term functions,R H,R I,and R C are parameterized to fit the data shown infigures1—LEFT and1—RIGHT.The R N function is included for completeness;k N is taken from Kurtz et al.(2000).N0is obtained by assuming k N is correct,and ascribing all readership of the Astrophysical Journal electronic edition which does not originate with ADS to the N mode. This is a very crude approximation,but the three component(R H,R I,and R C) model for archival readership is not effected by the N mode usage,which fades very rapidly following publication.The three mode model is not unique but does provide a very goodfit to the existing data,asfigures1—LEFT and1—RIGHT show.No model consisting of only two exponential functions canfit both the recent and historical data,as comparing the twofigures makes clear.Most studies of obsolescencefind that the use of the literature declines exponentially with age,and parameterize this with a single number,often called the“half-life,”which is related to the coefficient in the exponent by half-life= log e(2)/k,the point where the use of an article drops to half the use of a newly published article.There are several other definitions of half-life in the literature, we use this one.Thus the Historical(R H)component of equation C does not have a half-life;the half-life of the Interesting(R I)component is10.7years; the half-life of the Current(R C)component is1.7years.Kurtz et al.(2000) estimate the half-life of the New(R N)component at16days.Several studies(e.g.Egghe(1993)and references therein)decompose the exponential decay in use into the product of an intrinsic decay and the general growth of the literature.The results presented here are for the mean current use per article published as a function of time since the present,thus we measure directly the intrinsic decay.Kurtz et al.(2000)show the growth of the astro-nomy literature has been3.7%per year,measured in terms of number of papers published over the past22years.The total number of papers read over time in each mode is just the integral of the function from zero to infinity,which for a negative exponent is just the ratio of the two constants:H0/k H=∞reads(one and a half reads per year forever);I0/k I=818reads;C0/k C=275reads;N0/k N=100reads.This assumes no growth in the number of reads,If the number of reads per year increases long term at the3.7%at which the number of publications is now increasing the constants in the exponents would all be increased by0.037;this would have very little effect on the integrals of the R N and R C functions,but would more than triple the articles read in the R I mode;and the R H mode would grow apace with the growth in the number of reads.226M.Kurtz et al.1.2.DiscussionBeginning with Burton and Kebler(1960)there have been a number of studies (see White and McCain(1989)for a review)which suggest that the obsolescence function consists of the sum of two exponentials,which Burton and Kebler(1960) attribute to“classic”and“ephemeral”papers;parameterizations(e.g.Price (1965))tend to be similar to our R H+R I functions.If we ignore the R N component,which neither this study,nor any of the other studies of obsolescence could see,we still very clearlyfind three separate components to the obsolescence function.Why have these three components not been seen til now?We suggest that the data available to previous studies has not been adequate to see these subtle effects.Most studies have used citation data to determine the obsolescence function.Because it takes time after a paper is published for it to be cited(e.g.section2)the peak in the R C mode is obscured in citation data. Also citation studies have substantial problems accounting for the growth of the literature,which has not been at all constant over the past century.Related to this is the determination of the size of the sample universe(the number of relevant papers to the study)at past times.There are certainly other possibilities,perhaps the obsolescence function is different for reads and cites,and perhaps the very existence of the ADS has changed the way the literature is used.We will explore these questions further in section2.The reason why readership studies have not seen the three component nature of archival readership which we see,we suggest,is that the data available in such studies has been too sparse.The largest astronomy library,the Cen-ter for Astrophysics Library,has a reshelve rate of about1000/month(Coletti (1999)),which is less than0.2%of the rate of reads in ADS.Additionally many astronomers keep(and use)their own paper copies of recent journals,which would suppress the R C mode in library use.2.The relationship between reads and citesCentral to bibliometrics is the study of citations(Garfield(1979)),and central to the study of citations is the so called normative assumption(Liu(1993)) that“the number of times a document is cited...reflects how much it has been used...”(White and McCain(1989)).There have been many articles suggesting problems with citations studies(e.g.MacRoberts and MacRoberts(1989)),and many articles defending them(e.g.Small(1987)).White(2001)and Phelan (1999)discuss these issues.The readership data discussed in section1provide a totally independent, direct new measure of“how much(an article)is used.”Comparing the read-ership statistics with citation measures will show exactly the similarities and differences between citations,which are an indirect measure of use,but,some would argue,a direct measure of usefulness and reads,which are a direct meas-ure of use,but perhaps an indirect measure of usefulness.Here we expand considerably on the comparison presented in Kurtz et al.(2000).NASA ADS:Obsolescence of Reads and Cites2272.1.The mean relationship between reads and citesWhile there have been many dozens of studies on obsolescence using citations, and many dozen more using readership as determined by using library circulation statistics(see White and McCain(1989)for review),there are very few studies comparing the two methodologies over the same data.Tsay(1998)compared the readership obsolescence function(obtained by reshelving statistics)for a number of medical journals with the citation obsolescence function for the same journals. He found the half-life of the readership function was significantly shorter than the half-life of the citation function.Tsay(1998)reviewed the literature and found only one previous comparable study:Guitard,in1985(discussed in Line (1993)),using photocopy requests as the use proxy,found the citation half-life shorter than the readership half-life.We have only found two other studies.Cooper and McGregor(1994),also using photocopy data,find citation half-life substantially longer than the use half life;also theyfind“no correlation between obsolescence measured by pho-tocopy demand and obsolescence measured by citation frequency.”Satariano (1978)used the questionnaire method tofind“citation patterns reflect a cross-disciplinary focus that is not found in the journals most often read.”We believe Kurtz et al.(2000)contains thefirst study using a data-set large enough to show the similarities and differences between the two obsolescence functions.Here we use a substantially improved data-set;a complete discussion will be published in Kurtz et al.(2003).Synchronous relation Kurtz et al.(2000)found that the instantaneous obsol-escence function for articles from the recent technical astronomy literature as measured by citations is simply equal to a proportionality constant times the function measured by reads times an exponential ramp-up to account for the time delay from when an article isfirst published to when an article which cites that article is published:C=cR(1−e−k D T)(D) wherec≈0.05;k D=0.7The proportionality constant,c,represents the number of reads per citation. This changes with the(always incomplete)citation databases and with time,as the ADS use increases.Currently we estimate that the average paper is read about twenty times using ADS for every time it is cited.In comparing the citation and reads obsolescence functions we have adjusted c to provide the best fit to the samples.Figure2—LEFT compares the reads and cites obsolescence functions for re-cent articles.The readership data is for articles from The Astrophysical Journal, The Astronomical Journal,The Publications of the Astronomical Society of the Pacific,and The Monthly Notices of the Royal Astronomical Society which were read between1January2001and20August2001.The citation data are taken from those four journals and both Astronomy&Astrophysics and Nature,where the publication date was also between1January2001and20August2001.Only citations to one of the four journals in the readership sample were taken;the data contain45,000citations.228M.Kurtz et al.1975198019851990199520000.40.50.60.70.80.9123publication year 1900192019401960198020000.010.11publication year HCIFigure 2.LEFT:A comparison of the C =cR (1−e −k D T )model with the actual citations for papers from the 2001sample for the most recent 25years.The thick line shows the actual citations,the thin line is the model,using the actual reads,and the dotted line is the model using the reads model,equation C.RIGHT:A comparison of the C =cR (1−e −k D T )model with the actual citations for papers from the six year sample for the last 111years.The thick line shows the actual citations,the thin line is the model,using the actual reads,and the dotted lines are the modified reads model from equation C and its components.As can be seen from figure 2—LEFT the citation function follows the reads function very closely.In particular the R C function clearly has an analog in the citation data;despite the suppression of the steep increase compared with the raw reads due to the exponential ramp-up.The change in slope in the citation function seen beginning about 1994is exactly what is predicted from the reads function;the number of citations in 1998and 1999are more than 40%above that expected by an extrapolation of the exponential decay seen between 1975and 1990,a decay which corresponds very closely to the R I function.We suggest this shows that the citation derived obsolescence function has two components with exactly the same parameters as the two mid-range (in time)readership functions.To examine the obsolescence function over a longer time period we use a different dataset of citations.We take all citations to the four journals in the readership sample from articles published between 1January 1995and 20August 2001in the ADS database.The data contain 625,000citations.We continue to use as our comparison the 2001reads sample.Clearly papers published in 1995could not have cited papers published in 2000,so comparison with recent obsolescence is impossible.This comparison is in figure 2—LEFT.We use these data exclusively to examine the long term behavior of the obsolescence function.Figure 2—RIGHT shows the long term obsolescence function obtained from citation data compared with the readership function.They clearly are notNASA ADS:Obsolescence of Reads and Cites229 the same.The citation function follows the R I function but not the R H+R I function.This is not a statisticalfluke based on having a small number of citations;the number of citations in the period from1889to1940which are “missing”from the citation function exceed5,000.In the year1900,for example, there were18citations in the six year sample,about150would be expected, were the R H mode to produce citations at the same amplitude as the R I mode.We are therefore driven to the conclusion that:C=c(R C+R I)(1−e−k D T)(E) wherec≈0.05;k D=0.7for research articles in the astronomy literature.There are a number of possible reasons for the citation obsolescence function to be different from the reads function.There are also a number of possible reasons why the citation obsolescence function measured here does not show the R H component,whereas this component is seen in other citation based obsolescence functions,beginning with Price(1965).We see no clear candidate explanation which accounts for both differences,however.Discussion We have shown that the citation rate as a function of time is equal to a constant times the sum of two modes of the readership function.There is no a priori reason why the constant c in equation E should not actually be a function of time;why should the number of citations per read(about0.05)be constant,independent of the age of the article?Examiningfigures2—LEFT and2—RIGHT we see that if c is a function of time it cannot change by more than about1%per year.This is an extraordinary result,it says that within the(small)measurement error the C function and the R C+R I function must be measuring exactly the same thing,the mean usefulness of journal articles as a function of time.Because the private act of reading an article entails none of the various sociological influences as the public act of citing an article(Seglen(1997)lists several of these factors)this suggests that in the mean these factors do not influence the citation rate.Unless the sum of all the various sociological influences as a function of time is exactly the same as the usefulness of articles as a function of time the existence of these influences would cause c not to be constant.That c is constant means that at every age the total effect of these various influences is zero.We therefore assert that we have proven that the normative theory of citing (Liu(1993))is true in the mean.ReferencesBurton,R.E.and

①the study of the physical properties and of the transmission of speech sounds is called acoustic phonetics.研究语音的物理性质和传播的被称为声学语音学。

②the study of the way hearers perceive these sounds is called auditory phonetics.研究听者理解这些声音的方式的叫做听觉语音学。

③the study of how speech organs produce the sounds is called articulatory phonetics.研究发音器官如何发声的学科被称为发音语音学。

3. Characterize any discharge as unilateral or bilateral. Very focal disease such as an inhaled foreign body, dental abscess, or oronasal fistula is most likely to cause a unilateral discharge. Progressive disorders such as fungal rhinitis and neoplasia may cause a nasal discharge that is initially unilateral but progresses to bilateral. Systemic or diffuse disorders such as allergic rhinitis and lymphoplasmacytic rhinitis typically cause bilateral discharge.

(5 points)7.Try to understand the following two paragraphs, and describe and comment whattwo contrasting approaches or perspectives of language studies each of the quotes represent. (5 points)a) A human language is a system of remarkable complexity. To come to know ahuman language would be an extraordinary intellectual achievement for a creature not specifically designed to accomplish this task. A normal child acquires this knowledge on relatively slight exposure and without specific training. Thus language is a mirror of mind in a deep and significant sense. It is a product of human intelligence, created anew in each individual by operations that lie far beyond the reach of will or consciousness. ( Chomsky )b)It is fairly obvious that language is used to serve a variety of different needs, butuntil we examine its grammar there is no clear reason for classifying its uses in any particular way. This enables use to give an account of the different functions of language that is relevant to the general understanding of linguistic structure than to any particular psychological or sociological investigation.

It could mean "Above and across from one end or side to the other" and also "Completely through, from beginning to end".b) The IC analysis of the sequence "naughty boys and girls" could be illustrated like this:(naughty(boys and girls)) ((naughty boys)and girls)This makes the sentence interpreted differently as: "I dislike naughty boys and naughty girls "and "I dislike girls and naughty boys".In terms of semantics, the semantic feature of "and" results in the ambiguity of the sentence. It could combine individual words like "boys" and "girls", and also phrases like "naughty boys" and "naughty girls".c) According to Generative Grammar, the sentence can have two different deep structures.d) The verb "see" is semantically polysemous in that it could refer to "to perceive with eyes" and also "to understand". Similarly, the phrase "a piece of wood" could also be interpreted as the actual wood and the metaphorical meaning "a part of the whole thing". Thus, the sentence could be interpreted as "He saw with his eyes a piece of wood" as its literal meaning and "He understood only a small part of the whole" as the metaphorical meaning.e) The ambiguity results in the polysemous words ―drill‖ and ―bore‖ in the sentence. The word ―drill‖ could refer to an implement or a kind of training; and ―bore‖ means ―to make a hole with a drill‖ or ―to make weary by being dull‖. Therefore, the senten ce may probably mean ―She found that the drill was digging‖ and ―She found that the training was tedious‖.f) The polysemous characteristic of word ―lie‖ contributes to the ambiguity of the sentence. Generally speaking, this verb could refer to either ―to be or place oneself at rest in a flat, horizontal, or recumbent position‖ or ―to present false information with the intention of deceiving‖. Thus, the sentence could be interpreted as ―They are not telling the truth on the grass‖.g) The word ―match‖ could be interpreted in different ways: ―A pair, each one of which resembles or harmonizes with the other‖, or ―A game or context‖, or ―A narrow piece, usually of wood or cardboard, coated on one end with a compound that ignites when scratched against a rough o r chemically treated surface.‖ Therefore, the meaning if the sentence is correspondingly ambiguous.h) ―On the train‖ could be interpreted differently due to the nature of ―on‖. One is to interpret this phrase referring to location, and the other is to tak e it ―relating to the train, concerned with the train‖. Correspondingly, the sentence has two different meanings: ―The place he decided was on the train‖ and ―He made a decision about the train‖.i) The ambiguity results in different ways to treat the sequ ence ―Mary and Jack or Bill‖.To illustrated in IC analysis would be like this:(Mary and (Jack and Bill)) ((Mary and Jack) or Bill)In terms of semantics, the semantic feature of ―or‖ results in the ambiguity of the sentence.It could combin e individual words like ―Jack‖ and ―Bill‖, and also phrases like ―Mary and Jack‖ and ―Bill‖.j) The sentence could be interpreted differently in respect of the deep structure.The identicalness of the possessive adjective case and the objective case of the pronoun ―she‖ contributes to the ambiguity of the sentence. When ―her‖ is regarded as the objective case, it would be taken as the indirect object of the verb ―fed‖; when ―her‘ is seen as the possessive adjective case, it then would be take as the modif ier of the noun ―dog‖.Section Foura)The candidate repeated the answer.b)His solution was as good as hers.c)He made a number of clear expressions much to the audience‘s delight.d)The exam was very challenging, and I kept trying to finish on time withoutmaking too many errors.e)Many students profit from the research people.f)Her gossip was of a sordid character.g)In spite that she is lazy, I like her.h)Speed is also important.i)He glanced at her suspiciously.j)She seldom talks on any controversial subjects.Section Five1.English employs four kinds of juncture for differentiating words and phrases.There is close juncture for intra-syllabic segments, syllable juncture between syllable, rhythm juncture between words, and pause juncture. Different junctures reflect different levels in the prosodic structure hierarchy in continuous speech.For example, as to the word ―bird‖ [bə:d], the juncture between [b] and [ə:] makes them realized distinctly and so is the transition from [b] to [ə:]. And the diphthong [iə] reveals the intra-syllabic juncture of the wor d ―here‖[hiə]. Juncture words cause such differences in sound as that created by the pronunciation of blackbird (one word) and black bird (two words).2. A morph is the phonetic realization of a morpheme. In some sense it correspondsto a wordform. A morpheme is manifested as one or more morphs (surface forms) in different environments. These morphs are called allomorphs. Anallomorph is a morph that has a unique set of grammatical or lexical features. For example, /z/ in ―dogs, beds‖; /s/ in ―cats‖; /iz/ in ―garages‖ , all these three morphs are different representations of the same morpheme of plurality. Because they belong to the same morpheme, they are also called allomorphs.3.undesirable gentlemanly replacements4.a)A b) B c) A d) B e) B f) A g) B5.There are certain structural differences between poetic language and standardlanguage. These violations or de-automatizations or foregroundings or differences are called deviations. Leech has classified nine types of deviation.(1) Lexical deviation. Neologism refers to the invention of new words, but we call some new words nonce-formations if they are made up ―for the nonce‖, that is , for a single occasion only, rather than as serious attempts to augment the English word-stock for some new need. For example, in Hopkins‘ poem The Wretch of the Deutschland, ―The widow-making unchilding unfathering deeps.”(2)Grammatical deviation. An example of this type of deviation is illustrated in the repetition of generative construction. ―Our hearts‘ clarity‘s health‘s fire, our thoughts‘chivalry‘s throng‘s Lord.‖(Hopkins, The Wretch of the Deutschland)(3) Phonological deviation.(4) Graphological deviation.(5) Semantic deviation. It is reasonable to translate semantic deviation mentally into ―nonsense‖or ―absurdity‖, so long as we realize that ―sense‖is used in strictly liter-minded way. For example, ―The child is the father of the man‖(a line from Wordsworth.)(6) Dialectal deviation. Dialectism is the borrowing of features of regionally defined dialects. It is quite often used by storytellers and humorists. For example, in The Shepherd‘s Calendar, Spencer uses homely provincial words like ―heydeguys‖ (a type of dance), ―rontes‖ (young bullock), and so on..(7) Deviation of register.(8) Deviation of historical period.(9) The use of foreign language. The use of foreign language may suggest the speaker‘s high education or an attempt to catch fashion. It is often found in literature. For example, many Chinese people use some foreign languages while speaking in Chinese ―见面说hello,来是come,去是go‖.6. 参见北京师范大学2003年“英语语言学”题Ⅴ答案。

• 1. 2. • Stratified squamous epithelium: nasal orifice. locus of the nasal hairs (vibrissae). Pseudostratified columnar respiratory (ciliated) epithelium: 1. the remainder of the nasal vault. 2. paranasal sinuses.
Innervation of the nasal mucosa
• Nasal airflow: 1. trigeminal nerve: tactile, thermal, and possibly chemical sensation. 2. nervous reflexive airflow monitoring: nasal vestibule (tactile hair, Iggo dome, Pacinian, and Meissner receptors)
Histology
Respiratory epithelium: Goblet cells (g). Ciliated cells (c). Intermediate cell (l). Basal cells (b). Basement membrane (bm).
Histology
• Goblet cells produce a protective mucous layer(salts, glycoproteins, polysaccharides, and lysozymes). • The mucous layer can entrap inspired bacteria or viruses, particulate matter, and toxins. • Mucosal cilia can remove wastes for digestion and excretion.
Vascularization of nasal mucosa
• Artery: 1. ECA maxillary and facial branches. 2. ICA ophthalmic branch ethmoid arteries. • Vein: 1. anterior facial vein, sphenopalatine vein, ethmoid vein. 2. sphenopalatine and ethmoid vein cavernous sinus.
Functions of the nose
Chemosensation Olfactory sensation detects irritants, chemicals, and temperature abnormalities of inspired air Nasal reflex Nasal sensation may be linked to lower respiratory and vascular reflexes Olfactory identification of major proteins may be used in mate selection for production of off spring with more heterogenous HLA types
History
• • • • Time of onset. Duration of symptoms. Obstruction (unilateral or bilateral). Duration of the obstruction (recurrent or chronic). • Contributing factors in the patient’s environment.

Innervation of the nasal mucosa
• Sensory innervation: 1. olfactory nerve , trigeminal nerve (V1, V2). 2. olfaction, reflexes (sneezing, laryngeal constriction, bronchoconstriction, and cardiovascular responses). • Autonomic nervous: 1. vascular tone, turbinate congestion, nasal secretions. 2. parasympathetic: vasodilator, secretomotor activity. 3. sympathetic: vasoconstrictive.
