大空间建筑侧下送风热环境的实验研究

针对大空间建筑室内空调气流组织采用侧下送风的情况,研究了不同空气送风量和不同室外气象参数等条件下室内热环境的特性.实验结果表明,各工况下室内垂直温度分布具有良好的相似性,实验范围内最大垂直温差可达20℃,且该值随综合空气温度呈线性变化.室内上部、中部、下部3个区域的垂直温度梯度各不相同,空气送风量和室外综合温度对上部和下部区域垂直温度梯度的影响较大,对中部区域影响较小.此外,因风速较低,各工况下人员活动区域舒适性预期评价略偏高,人体头足垂直温差一般超过3℃.     

Extraction of color-intensity feature towards image authentication

A color-intensity feature extraction method is proposed aimed at supplementing conventional image hashing algorithms that only consider intensity of the image. An image is mapped to a set of blocks represented by their dominant colors and average intensities. The dominant color is defined by hue and saturation with the hue value adjusted to make the principal colors more uniformly distributed. The average intensity is extracted from the Y component in the YCbCr space. By quantizing the color and intensity components, a feature vector is formed in a cylindrical coordinate system for each image block, which may be used to generate an intermediate hash. Euclidean distance is modified and a similarity metric introduced to measure the degree of similarity between images in terms of the color-intensity features. This is used to validate effectiveness of the proposed feature vector. Experiments show that the color-intensity feature is robust to normal image processing while sensitive to malicious alteration, in particular, color modification.     

Notes of k-smoothness in Orlicz sequence spaces

The criterion for k-smooth points of the Orlicz sequence space endowed with the Orlicz norm is proved. The necessary and sufficient conditions of k-smoothness of l M and l （M ） are obtained, respectively. Finally, we give the counterexamples which show that previous results are not true.     

柳永慢词中的时空关系

慢词因其体制较长而有了比小令更多的抒情空间。柳永是我国第一位大力创作慢词的专业词人,柳词的情感往往在时空频频转换中一波三折。他表示时间推演的方式有白描直写、自然风物、常识推断、心理活动动词、隐晦典故等;表示空间挪移的则有相关名物、标志符号、＂介词＋名词＂、动作暗示、转换口吻、词意分析等方式。这些模式套路对后世词人创作慢词大有借鉴意义。     

论豫南皖西杠天神仪式展演的空间基础——以河南省新蔡县余围子乡吕胡刘村吕庄的杠天神仪式为例

豫南皖西杠天神仪式是在一个特殊的文化空间中进行的一种特殊的民间信仰活动。近些年来,随着杠天神仪式的复苏,直接影响到豫南皖西农村组织结构和信仰结构的回归。文章以河南省新蔡县余围子乡吕胡刘村吕庄的杠天神仪式为案例,从社会空间、文化空间和演仪空间三个方面来探讨以传统农耕文化为核心姓氏村落,在自给自足生产方式和生活习惯的主导下,构成家族式的社会结构群体,因而实现了信仰家族化的社会理解。

“与其p,不如q”句式在语篇中的信息传递功能

在同一话题的语篇中,＂与其p,不如q＂句式在信息传递方面起着＂承上启下＂的作用。这种＂承上启下＂的信息传递功能具体体现在＂原因1→观点→原因2＂模式、＂原因→观点＂模式、＂观点→原因＂模式、＂原因→观点→行为＂模式和＂原因→观点→目的＂模式中。

Bilateral shear strength of rectangular frame column based on simplified space truss-arch model

To investigate the bilateral shear strength of rectangular frame column subjected to oblique horizontal load, we presented a simplified space truss-arch model developed from unilateral truss-arch model. Main parameters in the new model were the cross-sectional area, transverse reinforcement raito, axial load, and material strength of the column. The reduction coefficient of concrete sterength owing to the severe cracking of column was also introduced in the model. Finally, 14 specimens under oblique horizontal load were tested to verified the feasibility and applicability of the space truss-arch model.
