алые паруса的先例分析

"先例现象"是语言文化学研究的关键概念之一。алыепаруса(红帆)这一典型的民族先例现象承载着丰富的民族文化内涵。它来源于俄罗斯浪漫主义作家格林的中篇小说《红帆》(Алыепаруса)。本文以先例理论为依托,通过分析алыепаруса不同形式的复现,揭示了它作为先例现象所体现出的称名功能、情感表现力功能、取信功能和象征功能,力求化抽象为具体,将先例理论更加全面、合理地运用于言语实践分析,构建分析具体先例现象的模型

Анализ диффузности языка в русском рекламном тексте

模糊性是自然语言的本质属性。模糊语在言语交际中有着广泛的运用，在俄语的广告语中也不例外，主要表现在语音、词汇和语句三个层面。广告最重要的目的在于吸引消费者并引起消费者的购买欲望。因此，广告文本的设计就显得尤为重要，而在广告文本中模糊语的运用对吸引消费者的注意并传达一定的信息有着重要作用。本文以模糊语言学与模糊修辞学为主要理论基础，深入分析了模糊语在广告文本中的运用，对俄语广告语的模糊性特点、作用、表现方式、修辞效果及负效应等做出了详细的论述和举例，以求对俄语学习者和相关工作者正确、全面地理解俄语广告语有所帮助。 本文主要分为三个部分：序言、正文和结论。 序言中主要介绍了本文的语料来源、研究...Диффузность – одно из универсальных свойств языковых явлений.

Effects of wall temperature on boundary layer stability over a blunt cone at Mach 7.99

Effects of wall temperature on stabilities of hypersonic boundary layer over a 7-degree half-cone-angle blunt cone are studied by using both direct numerical simulation (DNS) and linear stability theory (LST) analysis. Four isothermal wall cases with Tw/T0= 0.5, 0.7, 0.8 and 0.9, as well as an adiabatic wall case are considered. Results of both DNS and LST indicate that wall temperature has significant effects on the growth of disturbance waves. Cooling the surface accelerates unstable Mack II mode waves and decelerates the first mode (Tollmien–Schlichting mode) waves. LST results show that growth rate of the most unstable Mack II mode waves for the cases of cold wall Tw/T0=0.5 and 0.7 are about 45% and 25% larger than that for the adiabatic wall, respectively. Numerical results show that surface cooling modifies the profiles of rdut/dyn and temperature in the boundary layers, and thus changes the stability haracteristic of the boundary layers, and then effects on the growth of unstable waves. The results of DNS indicate that the disturbances with the frequency range from about 119.4 to 179.1 kHz, including the most unstable Mack modes, produce strong mode competition in the downstream region from about 11 to 100 nose radii. And adiabatic wall enhances the amplitudes of disturbance according to the results of DNS, although the LST indicates that the growth rate of the disturbance of cold wall is larger. That because the growth of the disturbance does not only depend on the development of the second unstable mode

A New High Order Accurate Shock Capture Method with Wave Booster

A new kind of shock capturing method is developed. Before applying the high order accurate traditional scheme which is called as base scheme in this paper the fluid parameters are preconditioned in order to control the group velocity. The newly constructed scheme is high order accurate, simple, has high resolution of the shock, and less computer time consumed

Direct numerical simulation of hypersonic boundary layer transition over a blunt cone with a small angle of attack

The direct numerical simulation of boundary layer transition over a 5° half-cone-angle blunt cone is performed. The free-stream Mach number is 6 and the angle of attack is 1°. Random wall blow-and-suction perturbations are used to trigger the transition. Different from the authors’ previous work [Li et al., AIAA J. 46, 2899(2008)], the whole boundary layer flow over the cone is simulated (while in the author’s previous work, only two 45° regions around the leeward and the windward sections are simulated). The transition location on the cone surface is determined through the rapid increase in skin fraction coefficient (Cf). The transition line on the cone surface shows a nonmonotonic curve and the transition is delayed in the range of 0° ≤ θ ≤ 30° (θ = 0° is the leeward section). The mechanism of the delayed transition is studied by using joint frequency spectrum analysis and linear stability theory (LST). It is shown that the growth rates of unstable waves of the second mode are suppressed in the range of 20° ≤ θ ≤ 30°, which leads to the delayed transition location. Very low frequency waves VLFWs� are found in the time series recorded just before the transition location, and the periodic times of VLFWs are about one order larger than those of ordinary Mack second mode waves. Band-pass filter is used to analyze the low frequency waves, and they are deemed as the effect of large scale nonlinear perturbations triggered by LST waves when they are strong enough.The direct numerical simulation of boundary layer transition over a 5° half-cone-angle blunt cone is performed.
