Particle-based derivations of the Fresnel equations appear not to exist. Approach: The objective of this work was to derive the basic optical laws from first principles from a particle basis. The particle model used was the Cordus theory, a type of non-local hidden-variable (NLHV) theory that predicts specific substructures to the photon and other particles. Findings: The theory explains the origin of the orthogonal electrostatic and magnetic fields, and re-derives the refraction and reflection laws including Snell’s law and critical angle, and the Fresnel equations for s and p-polarisation. These formulations are identical to those produced by electromagnetic wave theory. Contribution: The work provides a comprehensive derivation and physical explanation of the basic optical laws, which appears not to have previously been shown from a particle basis. Implications: The primary implications are for suggesting routes for the theoretical advancement of fundamental physics. The Cordus NLHV particle theory explains optical phenomena, yet it also explains other physical phenomena including some otherwise only accessible through quantum mechanics (such as the electron spin g-factor) and general relativity (including the Lorentz and relativistic Doppler). It also provides solutions for phenomena of unknown causation, such as asymmetrical baryogenesis, unification of the interactions, and reasons for nuclide stability/instability. Consequently, the implication is that NLHV theories have the potential to represent a deeper physics that may underpin and unify quantum mechanics, general relativity, and wave theory.展开更多

文摘In the campus greening design,the shrub height is generally consistent with people’s horizontal line of sight,which plays a significant role in people’s visual focus.From the perspective of ornamental characteristics of plants,the application of shrub landscape is explored in a campus environment.Based on the analysis of the selection,arrangement and maintenance of shrub plants in campus gardens,the application of shrub landscape on campus was evaluated comprehensively from the theoretical analysis of plant ornamental characteristics and campus shrub landscape.Based on the research background of the problems existing in the application of shrub landscape on campus,this paper first collected and sorted out the relevant theories extensively,and then conducted in-depth research on the relevant theories by using analysis methods such as literature data,field investigation and questionnaire survey.The results will provide a theoretical guidance and practical advocacy for campus garden planning and design,and help to create a livable and comfortable campus environment.It is hoped that the results will have some references for future campus shrub landscape and play a certain promoting role.
文摘As urban construction enters the era of stock development,the overall spatial environment of the main campus of North China University of Technology also needs to be updated.In this paper,the traffic network in the campus is extracted to draw the axis map,and the space syntax theory of Depth Map software is used to quantitatively analyze the integration and intelligence degree of the main campus of North China University of Technology.It is found that the overall spatial integration and intelligence degree of the campus are high,but the local space shows poor accessibility and insufficient space carrying capacity.Specific spatial optimization measures are proposed for the corresponding problems.The study compares and analyzes the experience information obtained from actual research with the quantitative index data,integrates the respective advantages of qualitative and quantitative analysis,and hopes to provide a certain theoretical basis for the construction of related campus space.

文摘Due to the differences in disciplines and regional cultural spirits,the campus landscape of Chinese universities has varying cultural connotations.Campus landscape is not only a reflection of regional school history and culture,but also a potential factor affecting students'ideology and values.At present,some colleges and universities in China only concern and consider the visual impact effect of campus landscape construction,while others take landscape planning and construction as an accessory of the main building,which seriously affects the soul guiding role of campus culture in campus landscape.The internal and external landscape pattern of Henan University of Science and Technology with landscape road and water system as the framework,as well as core scenic spots with rich cultural connotations,such as“Peony Dinghu map”,“Yueqin Lake”,embody the university history and culture,the characteristics of western Henan architecture and the specific campus culture positioning,providing a stark example for landscape planning and design of other colleges and universities in the future.

文摘A good sound environment is essential in creating a harmonious and peaceful campus,improving students’learning outcomes,promoting physical and mental health,and creating a green and healthy campus.This study investigated the impact of new buildings on existing ones by optimizing the spacing between new buildings and the sound insulation structure of building enclosures.The results indicated that building 4 was affected by the noise from new building 1 and its surroundings,with a maximum outdoor daytime noise level reaching 69 dB,and the indoor background noise level in the least favorable classroom was 43.73 dB,less than 45 dB,which was within the acceptable range.It is recommended that the sound insulation design be improved in the planning of new teaching buildings.Besides,the surrounding traffic conditions should be improved,and the usage time of sports facilities should be scheduled appropriately to prevent the noise from sporting activities from affecting the classroom activities.The findings of this study provide valuable references for future architectural acoustics design and campus planning,contributing to the creation of peaceful and comfortable campus environments.

文摘The major phytoplankton was investigated and analyzed in landscape water of six campuses in Nanjing Xianlin University Town,and water quality was evaluated by single factor assessment method and comprehensive weighted evaluation method.The result showed that the major phytoplankton groups were Cyanophyta,Chlorophyta and Bacillariophyta.Besides,each evaluation indicator showed that waterbodies in four campuses were eutrophicated and result of single factor evaluation showed water quality all belonged to poor category V.The result of comprehensive weighted assessment showed that waters in Nanjing Normal University and Nanjing University of Posts and Telecommunications were seriously polluted,cyanobacterial bloom appearing.Waters in Nanjing University of Chinese Medicine and Nanjing Forest Police College hadn't been eutrophicated.
