摘要：This research studies the features of chest and abdominal breathing in Zhuang *** participants were recruited to record 30 news articles of Zhuang *** chest and abdominal breathing signals as well as speech signal were recorded simultaneously. Programs for breathing analysis have been written to extract parameters such as breathing reset amplitude, time of inhale phase, and slope of exhale phase. The results show that the times of inhale and exhale reset of abdominal breathing are earlier than chest breathing, the breathing reset is related to prosodic boundaries

摘要：This paper analyses the chanting of 21 five-syllable modem-style poems, which is Chinese traditional style of poem reciting with cadence and pleasant melody, in order to fmd out the prosodic hierarchy according to pause duration, and probe the phonetic features and methods of chanting. Results reveal that pause exists after ＂level-level＂ tonal combinations, which is a kind of metrical pattern of Chinese poetry. The duration of syllables doubles in sentence final position. An exclamation is added when the sentence ends with a checked syllable. The pitch of syllables with level tone is lower than that of syllables with oblique tones, alternation of level and oblique tones forms the chanting melody. Sentences and poems with same metrical pattern have the same chanting melody.

摘要：目的通过正交设计结合层次分析法与加权综合评分法优选当归烟熏工艺。方法以当归药材的醇溶性浸出物含量,挥发油提取率,阿魏酸,Z-藁本内酯,正丁基苯酞,正丁烯基苯酞为指标,测定烟熏当归药材各个指标后,采用层次分析法确定各指标权重,得到综合评分。结果烟熏的温度、时间和发烟材料的量对烟熏当归的质量均具有显著性影响。最终确定的烟熏工艺条件为烟熏温度50℃,时间8h,发烟材料3kg。结论采用AHP与综合评分法可以用来优选当归烟熏工艺,可以节省劳动力,提高中药加工效率,为当归生产的产业化和标准化生产提供了理论依据。

摘要：为了有效解决无线多媒体传感器网络中多视角视频监控传输数据量大以及网络能量、资源受限的问题,提出了一种基于分布式压缩感知的高压缩率多视角视频编解码方法。对多视角视频序列进行分组处理,并将图像组分为关键帧和非关键帧;对关键帧采用基于压缩感知(compressed sensing,CS)的编解码方法进行处理;而在非关键帧的编码端采用联合稀疏表示方法对残差图像稀疏表示,解码端利用帧间时间相关性和多视角空间相关性预测生成当前视频帧,并借助差异补偿方法进一步提高预测准确性,同时提高了重构效果。实验结果表明,该方法取得较高的压缩率,重构出的图像质量比参考方法更高,且PSNR值得到了较大的提高。

摘要：A 1 550 nm long-wavelength vertical cavity surface emitting laser （VCSEL） on InP substrate is designed and fabri- cated. The transfer matrix is used to compute reflectivity spectrum of the designed epitaxial layers. The epitaxial layers mainly consist of 40 pairs of n-AlxGayIn（l-x-y）As/InP, and 6 strain compensated AlxGayln（l-x-y）As/InP quantum wells on n-InP substrate, respectively. The top distributed Bragg reflection （DBR） mirror system has been formed by fabricat- ing 4.5 pairs of SiO2/Si. The designed cavity mode is around 1 536 nm. The dip of the fabricated cavity mode is around 1 530 nm. The threshold current is 30 mA and the maximum output power is around 270 μW under CW opera- tion at room temperature.

摘要：以斗杆结构强度为基准,采用结构优化的方法,设计了大型液压挖掘机正铲工作装置斗杆新结构。采用离散元方法,构建矿山岩石模型,获得铲斗挖掘阻力;采用多体动力学方法,搭建大型液压挖掘机正铲工作装置刚柔耦合动力学模型,获得挖掘机斗杆挖掘工况斗杆动态载荷,并对斗杆进行动态结构强度分析;采用SIMP插值函数的变密度拓扑优化方法,在有限元中对斗杆结构进行拓扑优化设计,获得大型液压挖掘机正铲工作装置新型斗杆结构;对新型斗杆结构进行动态结构强度分析,斗杆结构强度保持原有水平。研究结果表明,通过拓扑优化后得到的新型斗杆,结构强度与类比设计一致,但质量减小。

摘要：玄关是现代住宅中的重要组成空间,承担着组织流线、换鞋更衣、储物等多样的功能。通过对玄关内必要家具尺度和各类活动所需人体操作空间的分析,提出了玄关空间的最小净尺寸;对开放式、"一"字型及"L"型布局玄关的特征进行分析,并提出了相应的空间设计方法。

摘要：明清两代是女性文学颇为繁兴的时期,仅以词名家者便指不胜屈,满族女词人顾太清就是其中特为杰出的一位。太清作品颇丰,现存词三百多首,集中涉及怀人、咏物、题画、交游、节序、游览、哲理、咏史、写怀、述景等多个方面,体现了她开阔多变的创作视野。而从艺术风格来说,太清词一反大多数女性词的柔婉纤丽,重视气格的峻拔与境界的高浑,展示出深稳沉着的大家风范。由太清的诗词诸作可以看出,她虽是女子,个性里却带着古代女性少有的俊爽洒脱,交游广阔又阅历丰富。尽管平生遭际坎坷,然始终不改其坚强豁达的本性,而这些也都一一反映在她的词作中,形成了与众不同的艺术风貌。
