从术语学论"韵"和"韵部"的定义

术语学要求各门学科的术语统一，内涵确定，层级、序列合理。目前汉语音韵学的“韵”和“韵部”不符合这一要求，给学习和研究增加困难。汉语音韵学韵母方面的音韵单位可由“韵类”、“韵”、“韵部”、“韵组”、“韵摄”分为五级，从小到大形成术语系列。     

Glare Generation Based on Wave Optics

This paper proposes a novel and general method of glare generation based on wave optics. A glare image is regarded as a result of Fraunhofer diffraction, which is equivalent to a 2D Fourier transform of the image of given apertures or obstacles. In conventional methods, the shapes of glare images are categorized according to their source apertures, such as pupils and eyelashes and their basic shapes (e.g. halos, coronas, or radial streaks) are manually generated as templates, mainly based on statistical observation. Realistic variations of these basic shapes often depend on the use of random numbers. Our proposed method computes glare images fully automatically from aperture images and can be applied universally to all kinds of apertures, including camera diaphragms. It can handle dynamic changes in the position of the aperture relative to the light source, which enables subtle movement or rotation of glare streaks. Spectra can also be simulated in the glare, since the intensity of diffraction depends on the wavelength of light. The resulting glare image is superimposed onto a given computer‐generated image containing high‐intensity light sources or reflections, aligning the center of the glare image to the high‐intensity areas. Our method is implemented as a multipass rendering software. By precomputing the dynamic glare image set and putting it into texture memory, the software runs at an interactive rate.     

论单音节字词测试项对普通话水平测试信度的影响

由于受到各种条件的限制,普通话水平测试内容本身对其信度有一定的负面影响.就单音节字词测试项而言,存在以下几个方面的问题：在选字上存在难和偏的问题;单音节形式及排列方式与认读习惯不一致;声调分布不均衡,且上声调值常受动态调值的影响;容易造成应试人心理压力等.为了提高测试信度,我们建议针对不同的测试对象,采用不同类型的测试试题.     

论诸葛亮的悲剧

本分析了《三国演义》中诸葛亮形象的悲剧表现，悲剧根源及所蕴藏的化意义，认为理想与现实的矛盾、孤独的境遇、性格心态的蜕变，使诸葛亮的命运具有强烈悲剧性特征，要全面正确地认识和评价诸葛亮，不能仅仅着眼于其才智与结局的反差，应全面把握分析其悲剧表现。     

IP电话系统中语音芯片的DSP实现

介绍了一种具有G．723．1语音编解码、自适应回声抵消DTMF编解码功能的语音芯片，以满足IP电话系统中低速率语音通信的需要。根据DSP内核的特点，对G．723．1算法进行了优化，降低了算法 复杂度；回声抵消部分使用归一化最小二乘（NL MS）自适应滤波器实现,采用Goertzel算法实现DTMF的检测。使用较少的资源,在一块TMS320C5402芯片上集成了以上全部功能。

多媒体钢琴标准音发声器

提出了一种利用多媒体计算机组成的钢琴标准音发生器,利用声卡可产生对应于钢琴１－８８键基音的标准音,而显示器则显示相应的界面,通过鼠标或外接脚踏开关可对发生器进行控制和操作。该发生器可用于钢琴的音准调整。     

VoIP技术与Wi-Fi结合的未来探讨

随着宽带通信和Wi-Fi接入点的日益增多,以及VoIP的日益普及,两种技术的融合已成趋势。IP语音传输(VoIP)提供了以低成本在网上打电话的方案,而Wi-Fi(一种无线传输的规范)扔掉了连线。如果两者相结合(现在这对组合已被称为VoFi),就可以通过任何能够访问的Wi-Fi连接,以低成本拨打无线电话。文中通过介绍VoFi相关工作原理以及VoFi目前还面临着音质的问题进行了深入地分析,对未来的发展提出了展望。

色阶重建技术已应用于高动态范围图像的处理中.应用色调映射技术和局部亮度适应性原理,提出了彩色图像增强的算法来改善彩色图像的可视性.使用一个参数自适应的可变基的对数函数对亮度图像进行变换,采用双边滤波技术来计算每一像素的局部适应亮度,再对彩色图像的对比度进行调整.实验结果显示,图像的暗区部分获得了较好的可视性和细节,同时对比度获得改善.     

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians.

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.
