类贝塞尔脉冲光束传输中的空间诱导色散效应

利用空间诱导色散概念,从理论上研究了等束腰宽度的类贝塞尔脉冲光束在自由空间中传输性质.在一阶近似的情况下,类贝塞尔脉冲光束的空间和时间部分可以做分离变量,空间部分在传输过程中保持类贝塞尔光束传输的特性,而时间波形部分的传输遵循空间诱导色散理论.利用数值模拟方法模拟了Bessel-Gauss脉冲光束和elegant Laguerre-Gauss脉冲光束的传输.结果证实,只要传输距离小于类贝塞尔光束的无衍射距离,空间诱导群速度色散理论能够很好地描述类贝塞尔脉冲光束脉冲形状的演化过程.

On the representation of elegance in EST translation

Scientific and technical literature and information focus on scientific truth, explaining natural phenomena objectively, probing into scientific issues, communicating research achievements and summarizing the experience. The language of technical articles should be concise and accurate. High-quality technical translation should also have aesthetic value, literary grace and elegant style. Many technical translators think that faithfulness and smoothness are the primary principles in technical translation, while elegance is just an ornamental standard which values little. The author considers elegance in EST translation should be the perfect unity of faithfulness and elegance. This paper analyses the criteria for technical translation, explores the representation of elegance in technical articles, and emphasizes that the literary value should be thoroughly appreciated.

Elegant Ince-Gaussian beams in a quadratic-index medium

Elegant Ince-Gaussian beams, which are the exact solutions of the paraxial wave equation in a quadratic-index medium, are derived in elliptical coordinates. These kinds of beams are the alternative form of standard Ince-Gaussian beams and they display better symmetry between the ]nce-polynomials and the Gaussian function in mathematics. The transverse intensity distribution and the phase of the elegant Ince Gaussian beams are discussed.

Elegant Ince-Gaussian breathers in strongly nonlocal nonlinear media

A novel class of optical breathers, called elegant Ince-Gaussian breathers, are presented in this paper. They are exact analytical solutions to Snyder and Mitchell＇s mode in an elliptic coordinate system, and their transverse structures are described by Ince-polynomials with complex arguments and a Gaussian function. We provide convincing evidence for the correctness of the solutions and the existence of the breathers via comparing the analytical solutions with numerical simulation of the nonlocal nonlinear SchrSdinger equation.

From an aging person to an elegant senior:a humanistic approach to viewing older adults

The continuing growth in the number of adults aged 60-plus has raised global alertness of population restructuring.This demographic change,on the one hand,reduces productivity and increases public expenditure due to aging,resulting in prejudice,bias,misrepresentation,and discrimination against them.On the other hand,it develops a specific consumer market segment and extends the availability and accessibility of the elderly through employment,volunteering,or grandparenting.This study argues against the stigmatization of this age group from a functional perspective that damages social cohesion.It advocates a humanistic view toward seniors to eradicate marginalization and promotes the manageability of the senior population.With the aid of advanced technology and health equity,senior adults can retain everyday competence for self-care with dignity,as well as gracefully attain physical and psychological health,autonomy,and well-being in their later life.All these considerations give medical and nursing professionals insight into how to take care of the elderly.

Species limits in the Elegant Pitta (Pitta elegans) complex from Wallacea based on bioacoustic and morphometric analysis

Background:The Elegant Pitta(Pitta elegans)complex displays a remarkable diversity of morphological and bioacoustic traits across five taxa currently recognized as subspecies.They differ in plumage characteristics(such as red versus black belly patches;supercilium color and extent;and white versus black throats),in lifestyle(resident versus migratory)and in vocalizations.We investigated the morphological,bioacoustic and ecological differences across all taxa after recent studies demostrated the importance of these traits in recognizing biological species limits across pittas.Methods:Morphometric analysis was carried out by measuring tarsus,wing,tail and bill lengths of 15 specimens at the Natural History Museum,UK,and plumages were inspected across 106 unique individuals from four different repositories.Bioacoustic analysis was based on 134 range-wide sound recordings.Two types of calls,territorial calls and alarm calls,were analyzed using different sets of parameters.Principal component analysis and the Isler Criterion were applied to the measurements.Playback trials were conducted to explore the levels of response of each taxon to the call types of the other taxa.Results:The territorial call of concinna exhibits a distinct two-element motif,while elegans,maria and virginalis utter a three-element motif in which the first two elements are given in quick succession.On the other hand,vigorsii,produces both two-element and three-element motifs with longer breaks in between elements.As further corroborated by the playback trials,the three taxa elegans,virginalis and maria form a tight vocal cluster,whereas each concinna and vigorsii are distinct.The alarm call turned out to be less diagnostic even though most taxa did roughly separate into different vocal clusters.Morphometric analysis failed to produce strong differences,but plumage distinctions among multiple taxa are pronounced.Conclusions:We suggest splitting the Elegant Pitta into three biological species based on bioacoustic and—less so—plumage evidence:(1)Temminck’s Elegant Pitta P.elegans(including subspecies elegans,virginalis and maria),(2)Wallace’s Elegant Pitta P.concinna(monotypic),and(3)Banda Elegant Pitta P.vigorsii(monotypic).

Comments on E-C translation of cosmetics directions

This paper argues that the translation principle of ＂faithfulness, expressiveness and elegance＂ is good enough to evaluate translations of cosmetics directions and there is no need to refer to other translation principles. This argument is supported by revising some poor translations of cosmetics directions.

Traditional Chinese Translation Discourses in Translation of Buddhist Texts--A Case Study on the Sūrangama Sūtra

The Chinese translation of the?ūra?gama Sūtra—Dafoding rulai miyin xiuzheng liaoyi zhu pusa wanhang shoulengyan jing大佛頂如來密因修證了義諸菩薩萬行首楞嚴經—is a unique classical work that articulates a specific Buddhist worldview,its recondite principles,and ways of practice.Unsurprisingly,it has attracted the attention of almost every school of Buddhism.The first full English translation of the sūtra was published by the Buddhist Text Translation Society(BTTS)in the 1970s—a decade when a number of newly established institutions embarked on the project of translating Buddhist texts into English for the first time.By contrast,China has been translating Buddhist scriptures for more than 1,000 years,which has given rise to a variety of translation discourses.Therefore,it makes sense to utilize these discourses when analyzing the recent translation of Buddhist texts into English.From the perspective of the three traditional Chinese translation discourses—Yan Fu’s three principles of fidelity,fluency,and elegance;Sengrui’s matching term and meaning;and Xuanzang’s five guidelines for not translating a term,this paper discusses translation issues by comparing the Chinese and English versions of the?ūra?gama Sūtra.This analysis reveals that the traditional Chinese translation discourses are valuable resources that should be respected in the contemporary translation of Buddhist texts into English.

Appreciating Ancient Chinese Poetry (Chinese-English Bilingual)

The following are two poems by well known chinese poet Li Qing zhao(1084-C.1151),who lived hme SouthernSong Dynasty(11 27-1279)、The poems are translated by Chinese Canadian N.C.Doc.Li Qingzhao was a native ofZhangqiu in Qizhou(now in Shandong Province).Her early life was spent in affluence,and she and her husband,Zhao Mingcheng,devoted themselves to collecting and arranging callgraphy,painting and seals.This idyllic lifecame to an end afterjin troops had invaded the Central Plain and moved to the south of China.Her early poetrydescribes mostly her leisure life,while her late works are full of sorrow for her husband,who had died,and for hernative land in the Central Plain.She writes in a straightforward manner,and her wording is both elegant and mild.
