Acoustics testing and simulation analysis of waiting hall in the line-side high-speed railway station

Integrated the flow density changes of the waiting hall in a line-side high-speed railway station, an on-site measurement of noise environment is carried out. The characteristics of the acoustic environment are discussed in this study. Furthermore, combining the measured data of the background noise, acoustic computer simulation program ODEON calculates the reverberation time and speech transmission index of public broadcasting system. The results indicate that the reverberation time exceeds 5 s and the speech intelligibility of the south waiting room and dining area in second floor is lower than 0.4. Against the existing problems, various scenarios for upgrading the acoustic environment of waiting room are presented and proved to be efficient. Moreover, from the optimization process, it is certificated that the requirement of speech intelligibility can be also satisfied when appropriately relaxing the reverberation time limits specified in the regulation.

Analysis of Chinese urban skyline night view's design elements

With the deepening process of Chinese urbanization, it becomes a worthy research topic how to get a night urban skyline view with good effects through design means. The main purpose of this article is to provide some references and ideas for night skyline planning and design by analyzing urban night skylines design elements.

Research on the hardware system of measurement on urban residential areas night light

The article refer to the problems in which measurement about urban residential areas lighting, on the basis of collecting related data and results in the field, and adopt the methods of intersecting architecture, urban planning, automation, computers, developing a suit of “measurement hardware system of urban residential areas lighting based on a platform for remote control vehicle”. The system can exactly and efficiently detect parameters such as illumination and brightness, at the same time, it can comprehensive and objective detect luminous environment, and supply technology endorsement on discovery for developing lighting standards of urban residential.

Evaluation system of aesthetics on nightscape lighting of classical Chinese garden

The article refers to the lack of evaluation system of aesthetics on nightscape lighting on classic garden, which can not supervise design of nightscape lighting on classic garden. The article serves Summer Palace as sample, establish impact factor and evaluation system of aesthetics on nightscape lighting of Summer Palace by adopting analytic hierarchy process, which provides easy to use evaluation and control tools of aesthetics on nightscape lighting of classic garden.

Study on chromatic light reappeared digital technology in architectural lighting environment

With using digital image technology, and in standardizing chromatic display device, the paper framed a mathematical conversion model based on computers and televisions. It put forward a quantitative restituting method of chromatic light for the research work on architectural lighting environment and design in practice. It made lighting scene and designing effect as true as possible restitute in the laboratory, so it can better apply to urban landscape illumination and design even more.

A quantitative study on color emotions for double chromatic light in landscape illumination

For the results of early quantitative studies on color emotions can not be used in large-scale light environment, the quantificational method of color emotions for the large-scale landscape illumination environment was put forward. In a psychophysical experiment, 21 large-scale double chromatic stimuli on 20 chromatic-light emotional scales were assessed. The factor analysis identified two double chromatic-light emotional factors: activity and evaluation. The paper predicted double chromatic-light emotions by monochromatic-light emotions values in arithmetic mean way, and figured out that the successfully predicted emotions factors are all from activity factor. The paper discussed the factors of double chromatic light emotions to build a scientific and efficient method of predicting chromatic light emotions quantitatively.

Notice of Retraction Digital research on standard of color about colored drawing of Summer Palace

For protectively mending colored drawing and assuring authenticity of world heritage, the article quantitatively research standard of color about colored drawing of Summer Palace, by adopting the method of testing colored drawing with Scientific Instruments in Site and analyzing data with software in laboratory, and reference traditional technology of colored drawing, ascertains digital standard of color and make standard color card about colored drawing of Summer Palace, which provides scientific foundation. for protectively mending colored drawing and assuring authenticity of world heritage.
