Phonetics of Chinese Dialects: An Instrumental Survey

為了解決Approximants的問題,作者Lee, Wai Sum 這樣論述:

This comprehensive study of the phonetic properties of the sounds of Chinese dialects is based on instrumental data on the articulatory, acoustic, and physiological properties of these sounds. It covers a range of topics, including the sound categories of plosives, fricatives, affricates, nasals, ap

proximants, vowels, diphthongs, triphthongs, and tones. The dialects covered are the representative members of the Chinese dialect groups, namely Guanhua (or Northern Chinese), Xiang, Gan, Wu, Min, Kejia (Hakka), and Yue. While many sounds are also found in other languages, there are those which are

unique to Chinese dialects or rarely occur in other languages. In some instances, Chinese dialect sounds and those of other languages may share the same IPA transcription but differ in articulatory and acoustic characteristics. Teachers, researchers, and students of linguistics, language studies, s

peech pathology, and speech science are expected to find this book informative and useful..

在高排斥力嵌段共聚物/均聚物混參系統之Frank-Kasper相及其形成機制之研究

為了解決Approximants的問題,作者穆斯塔法‧侯賽因 這樣論述:

嵌段共聚物自組裝可利用調整排斥力強度及組成的方式提供我們得到不同規則排列的奈米結構之方法。然而,在wet brush的條件下,將一個能均勻混到其中一微相結構中的均聚物混摻至嵌段共聚物中是一個能有效調控自組裝結構的方式。在高度不對稱的組成中,嵌段共聚物會形成微胞,這些微胞會進而排列成一個三維向度的結構,而這些立體結構中以體心立方結構最為對稱。近年的理論研究發現,當構型高度不對稱且主成分鏈鍛的Kuhn length較小時,若嵌段共聚物系統可形成微胞,則這些微胞會趨向形成Frank-Kasper相。此時,為了減少冠狀區域的高分子鏈鍛產生packing frustration,微胞中的球核區與冠狀區

域之介面會形變成Voronoi cell的形狀。在此研究中,我們利用強排斥力嵌段共聚物:聚苯乙烯-共-聚二甲基矽氧烷混摻聚苯乙烯均聚物,將系統調控在組成不對稱的區域來系統性的探討其自組裝結構及相行為。從先前文獻的結果得知,聚苯乙烯-共-聚二甲基矽氧烷屬於構型對稱的系統,此系統不應形成Frank-Kasper相。然而,聚苯乙烯與聚二甲基矽氧烷之間有極大的排斥力,因此趨向形成微胞來降低介面自由能。然而,我們發現即使在高度組成不對稱的情況下,由於純的嵌段共聚物擁有較強的排斥力,使得介面自由能主導整體自組裝行為,而形成六方堆積柱狀結構。若混摻一種比共聚物之聚苯乙烯鏈鍛還小分子量的聚苯乙烯均聚物,此時系

統會形成微胞結構,代表聚苯乙烯均聚物與共聚物之聚苯乙烯在冠狀區域中相互混合。於此系統中,聚二甲基矽氧烷所形成之球核主要會以體心立方結構的方式排列。有趣的是,在靠近六方堆積柱狀結構的附近,我們發現當均聚物分子量較小時,微胞將排列成Frank-Kasper σ 相。在升溫過程中,由於lattice fluctuation的緣故,使得微胞從近似準晶結構轉變成體心立方結構。此研究說明,即便在構型對稱的系統中,仍可利用混摻均聚物的方式來得到Frank-Kasper σ 相。

Progress in Approximation Theory and Applicable Complex Analysis: In Memory of Q.I. Rahman

為了解決Approximants的問題,作者Govil, Narendra Kumar (EDT)/ Mohapatra, Ram (EDT)/ Qazi, Mohamme 這樣論述:

Current and historical research methods in approximation theory are presented in this book beginning with the 1800s and following the evolution of approximation theory via the refinement and extension of classical methods and ending with recent techniques and methodologies. Graduate students, postdo

cs, and researchers in mathematics, specifically those working in the theory of functions, approximation theory, geometric function theory, and optimization will find new insights as well as a guide to advanced topics.The chapters in this book are grouped into four themes; the first, polynomials (Ch

apters 1 -8), includes inequalities for polynomials and rational functions, orthogonal polynomials, and location of zeros. The second, inequalities and extremal problems are discussed in Chapters 9 -13. The third, approximation of functions, involves the approximants being polynomials, rational func

tions, and other types of functions and are covered in Chapters 14 -19. The last theme, quadrature, cubature and applications, comprises the final three chapters and includes an article coauthored by Rahman.This volume serves as a memorial volume to commemorate the distinguished career of Qazi Ibadu

r Rahman (1934-2013) of the Universit de Montr al. Rahman was considered by his peers as one of the prominent experts in analytic theory of polynomials and entire functions. The novelty of his work lies in his profound abilities and skills in applying techniques from other areas of mathematics, suc

h as optimization theory and variational principles, to obtain final answers to countless open problems.

中文學習者在不同習得年齡對英文母音感知與發音之探討

為了解決Approximants的問題,作者高子涵 這樣論述:

本研究採用語音學實證研究方式,探討中文學習者在不同習得年齡對英文母音之感知與發音表現,並分析中英兩個語言共同的母音、母音空間面積、區辨與發音能力間的關聯性等影響表現的可能因素。研究對象共分為四組,小學生依英文習得年齡分為早期學習組與晚期學習組,成人依其母語分為英文母語組及中文母語組,每組皆為15人。實驗方法為中英文區辨能力測驗及中英文發音能力測驗,早期及晚期學習組完整參與四個測驗,成人只參與其母語之區辨及發音能力測驗。研究發現,早期學習者在區辨英文母音的能力上優於晚期學習者,但兩個語言共同的母音並非影響或促進他們區辨能力的關鍵因素。早期與晚期學習者表現上的差異也呈現在英文母音的發音測驗中,晚

期學習者呈現與英文母人士不同的母音空間面積,且在發音上受到母語的影響。然而,縱然早期與晚期學習者擁有不同的英文母音表現,他們的區辨能力與發音能力間都存在正相關,換言之,發音能力皆奠基在辨識能力之上。綜合以上實驗結果,英文習得年齡是影響中文學習者英文習得能力及是否接近母語人士表現的重要因素。
