屯堡方言声调系统共时历时比较

屯堡方言与周边方言声调的共时比较和历时追溯表明:屯堡方言与周边方言声调的区别特征主要体现在调值及入声的归并上.屯堡方言阴平调值是中平调33,是明代汉移民语音的底层;周边方言的高平调55,是清代汉移民语音叠置覆盖的结果;其余方言的次高平调44,则大多是中平调受到高平调影响而出现的一种过渡状态.入声归并上,屯堡方言全浊入声归阳平是填补舒声空位的结果,这与周边方言显示出很强的一致性;而其次浊声母和清声母入声字归阴平,这属于明代汉移民语音中的底层成分;周边方言乃至西南官话中这些字归阳平,则是清代汉移民语言对该方言进行重叠覆盖的结果.     

试论武平东留乡所属上四乡(六个自然村)客家话声调

上四乡指位于福建省龙岩市武平县东留乡西部的六个村子,该地所说的客家话具有区别于东留其它村庄客话的鲜明特色,这特别体现在古浊平调字大部分今读为去声,小部分读为今阳平、阴平;而少部分的今阳平字只在文读音中出现.     

基于受众心理视角下广告英语语言功能分析

依据话语的交际功能理论，结合受众的心理体验，从广告英语的语气、人称指代等角度探讨广告英语的语言特色，着重分析了广告话语中语气表达的运用和人称指代的变化与受众心理之间的互动作用，进而使受众成为潜在的消费者。同时，分析语气和人称指代的恰当使用，将有助于广告目标的实现。

An Accurate Characterization of CRT Monitor (I) Verifications of Past Studies and Clarifications of Gamma

CRT monitors are widely used to view images on the Internet. The color images on the computer graphic display can be printed out or displayed on other monitors through the Internet, and color matching between the original and the reproduction is very important. The color management systems (CMSs) are useful for the color matching. CMSs utilize device profiles, in which color characteristic information is stored, and these profiles are generated by device characterization. Thus, an accurate characterization of the monitor is essential for better color matching. CRT monitor characteristics can be described by the tone reproduction curves (TRCs) of each channel, and color additive matrix. In this paper, these characteristics were investigated from a physical point of view. Various kinds of flare and the interdependence among the channels were also investigated and verified. The definition of the term “gamma” is clarified, which is very often used to describe the TRC. Various definitions are compared and a new definition of S-γ is proposed.     

Effect of impinging plate geometry on the self-excitation of subsonic impinging jets

In the generation of discrete tones by subsonic impinging jets, there exists a difference of opinion as how the feedback is achieved, i.e., the path of the feedback acoustic waves is whether inside the jet or outside the jet? The only available model (Tam and Ahuja model) for the prediction of an average subsonic jet impingement tone frequency assumes that the upstream part of the feedback loop is closed by an upstream propagating neutral wave of the jet. But, there is no information about the plate geometry in the model. The present study aims at understanding the effect of the plate geometry (size and co-axial hole in the plate) on the self-excitation process of subsonic impinging jets and the path of the acoustic feedback to the nozzle exit. The present results show that there is no effect of plate diameter on the frequency of the self-excitation. A new type of tones is generated for plates with co-axial hole (hole diameter is equal to nozzle exit diameter) for Mach numbers 0.9 and 0.95, in addition to the axisymmetric and helical mode tones observed for plates without co-axial hole. The stability results show that the Strouhal number of the least dispersive upstream propagating neutral waves match with the average Strouhal number of the new tones observed in the present experiments. The present study extends the validity of the model of Tam and Ahuja to a plate with co-axial hole (annular plate) and by doing so, we indirectly confirmed that the major acoustic feedback path to the nozzle exit is inside the jet.     

文水方言音系结构的调整方式——以成山摄舒声字为例

介绍文水方言内部五点成山摄舒声字读音现状，并归纳其演变规律，认为其音系结构的调整是通过非平行演变和“无中生有”的方式实现的。在地域上呈现出中间慢、四周快的特点，细音字演变的速度最快，洪音中最先变化的是山摄合口字和开口见晓组字。文水方言[-n]韵尾消失，保留[-η]尾，符合北方大多数方言阳声韵韵尾脱落的顺序。
