| 1 | Optimization of Soundscape in Theme Park Based on Soundscape Comfortable Degree——A Case Study of China Dinosaur Land in Changzhou显示文摘Tourism soundscape is a new field of tourism landscape research, soundscape designs offer new concepts for the landscape research and development. Taking China Dinosaur Land in Changzhou City for example, visitors' perception about soundscape comfort in theme parks was studied. The researches found that acoustic comfort was infl uenced by objective parameters of sound and subjective perception of visitors, and when the soundscape volume stayed at a certain threshold value, visitors would gain the most satisfi ed acoustic comfort experience, and they were most sensitive to sound elements that able to convey cultural connotations of the theme park. On this basis, this paper adopted positive design, negative design, and zero design, and proposed the concepts of optimizing theme park soundscapes. | WANG Fang QIU Mengyuan SHA Run QIN Jingwen | 2014 | Journal of Landscape Research2014，6，2： | 1 |
| 2 | Topology-optimized thermal metamaterials traversing full-parameter anisotropic space显示文摘It is widely adopted in thermal metamaterials that mixing different materials could conveniently result in effective thermal conductivities(ETCs)beyond naturally-occurring materials.When multiple materials are isotropically mixed,the ETC is a direct average governed by their filling fractions and given bulk conductivities.That could lead to an inhomogeneous and anisotropic value within the maximal and minimal thermal conductivities of constituent materials.Usually thermal metadevices rely on anisotropic thermal conductivity tensor,whose tensorial elements are frequently inter-dependent and confined within a limited parametric space.It is thus nontrivial to establish a design recipe for advanced thermal metamaterials whose ETCs could cover full-parameter anisotropic space.We demonstrate topological functional cells(TFCs)with copper and polydimethylsiloxane,and show that the anisotropic ETCs traverse their full-parameter space.Such robust scheme based on topology-optimized TFCs unlocks unexplored opportunities for functional thermal metadevices whose parameters may not be reached in previous mixing approaches.This study also sheds light on the developments in emerging acoustic,mechanical and electromagnetic composite materials. | Wei Sha Run Hu Mi Xiao Sheng Chu Zhan Zhu Cheng-Wei Qiu Liang Gao | 2022 | npj Computational Materials2022，，1： | 0 |
