Jianzhu Gangjiegou Jinzhan, 2012 分析钢结构温度效应和确定施工合拢温度关键在于确定温度场的分布。在日照下,由于钢构件的温度场分布非常复杂和不均匀,而难以确定。基于ASHRAE晴空模型,采用ANSYS的APDL语言对箱型钢构件在夏至日日间的温度场进行了数值模拟,模拟中考虑了太阳辐射强度、对流换热系数、构件表面太阳辐射吸收系数等对构件温度场的影响。结果表明:夏至日构件最高温度高达78.411℃,最大升温高达44.803℃;太阳辐射强度、对流换热系数和构件表面太阳辐射吸收系数对日照下的箱型钢构件温度场的影响起主导作用。

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...

Zhejiang Daxue xuebao. Lixue ban, 2014 利用1960~2004年NCEP/NCAR全球再分析资料、SMIP2海温资料和我国160站逐月降水和气温观测资料，考虑到大气在从低纬到中高纬地区的能量传播的桥梁作用，首先对冬季印度洋海温距平场与同期北半球500 hPa位势高度距平场进行奇异值分解(SVD)，然后分析印度洋海温异常与我国冬季气温和降水的关系.研究结果表明，冬季印度洋海温距平场第1奇异向量(SVD1)是全区一致的单极型分布形势，与我国冬季气温和东南地区降水的相关性非常显著.当冬季印度洋海温距平场第1奇异向量处于正位相时，印度洋海温异常偏暖 ...

Research of Resonator-sound-generator Atomizing Nozzle [PDF]
, 2015 喷嘴技术的应用范围几乎包含所有工业领域、农业生产、交通运输以及人们的日常生活。作为必备组件在燃烧装置上的应用尤为重要。以往对于新型的流体动力式超声波雾化喷嘴研究表明：这类喷嘴的雾化粒径小（小于50μm）且分布均匀性好，对实现低氧燃烧、减少烟气中烟尘和氮氧污染物的排放有实质性的意义。因此本文以谐振腔式声能雾化喷嘴为研究对象，通过设计结构，利用FLUENT软件对其流场、声场以及雾化性能进行多参数的数值模拟，通过雾化性能的变化规律分析了其雾化机理。 研究首先基于哈特曼发声哨的原理设计了谐振腔式声能雾化喷嘴 ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
